  • Hermes Agent: The Self-Improving AI Agent That Learns From Every Conversation

    Hermes Agent: The Self-Improving AI Agent That Learns From Every Conversation

    Artificial intelligence agents are everywhere these days, but most of them share a fundamental limitation: they don’t really learn from their experiences. You have the same conversation with them repeatedly, and they never get better. Nous Research aims to change that with Hermes Agent, a new open-source project that bills itself as “the agent that grows with you.”

    A Memory That Actually Remembers

    Traditional AI assistants treat every conversation as a clean slate. Hermes takes a fundamentally different approach. It maintains persistent memory across sessions, creating skills from experience and improving them during use. The agent nudges itself to retain knowledge, searches through past conversations, and builds a deepening model of who you are over time.

    “The only agent with a built-in learning loop,” as the project describes itself, goes beyond simple context windows. While conventional agents can only work with what you tell them in the current session, Hermes actively works to preserve and apply knowledge from previous interactions. That customer you mentioned last week? Hermes remembers. That preference you expressed months ago? It’s still there.

    Works Everywhere You Do

    One of Hermes’s standout features is its multi-platform support. You can interact with it through Telegram, Discord, Slack, WhatsApp, Signal, or traditional CLI鈥攁ll from a single gateway process. Voice memo transcription and cross-platform conversation continuity mean you can start a conversation on your phone and continue it on your desktop without missing a beat.

    The agent runs on a VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. With Daytona and Modal, the agent’s environment hibernates when idle and wakes on demand. This means you get persistent assistance without persistent costs.

    Model Flexibility Without Lock-In

    Hermes doesn’t force you into a single AI provider. You can use Nous Portal, OpenRouter (with access to 200+ models), z.ai/GLM, Kimi/Moonshot, MiniMax, OpenAI, or your own endpoint. Switching models is as simple as running the model command鈥攏o code changes, no lock-in.

    This flexibility is particularly valuable for developers who want to experiment with different models for different tasks, or organizations that need to balance cost and performance across use cases.

    The Skills System

    Hermes includes a sophisticated skills system that allows the agent to create procedural memories and improve them autonomously. After completing complex tasks, the agent can create new skills that encapsulate what it learned. These skills then self-improve during subsequent use.

    The system uses FTS5 session search with LLM summarization for cross-session recall, and is compatible with the agentskills.io open standard. There’s also a Skills Hub where users can share and discover community-created skills.

    Research-Ready Architecture

    For AI researchers, Hermes offers batch trajectory generation, Atropos RL environments, and trajectory compression for training the next generation of tool-calling models. The project was built by Nous Research, the team behind several notable open-source AI projects.

    The installation process is straightforward鈥攔un a single curl command and you’re chatting with your new AI assistant in minutes. Windows users need WSL2, but Linux and macOS are supported natively.

    Migration from OpenClaw

    Interesting twist: Hermes can automatically import settings from OpenClaw, including persona files, memories, skills, API keys, and messaging configurations. If you’re already running an AI assistant setup, moving to Hermes is designed to be painless.

    With over 12,000 stars on GitHub, Hermes represents an interesting evolution in the AI agent space. Instead of just providing a static set of capabilities, it attempts to create a genuinely learning system鈥攐ne that gets better at helping you specifically, over time.

    The MIT-licensed project welcomes contributions and has an active Discord community for support and discussion. Whether you’re an individual looking for a more personal AI assistant or an enterprise exploring agentic workflows, Hermes offers a compelling combination of memory, flexibility, and self-improvement that sets it apart from the crowded agent space.

  • MoneyPrinterV2: The Open-Source AI Tool That’s Automating Online Income (And Sparking Debate)

    MoneyPrinterV2: The Open-Source AI Tool That’s Automating Online Income (And Sparking Debate)

    It has nearly 25,000 GitHub stars and has earned over 2,900 stars in a single day. Love it or question it, MoneyPrinterV2 is impossible to ignore. The project, officially described as “an application that automates the process of making money online,” is one of the most talked-about open-source AI tools on GitHub right now.

    Created by developer FujiwaraChoki, MoneyPrinterV2 is a complete rewrite of the original MoneyPrinter project, built with a modular architecture and a much wider feature set. It leverages AI models — including gpt4free for text generation and KittenTTS for voice synthesis — to automate the creation and distribution of online content at scale.

    What MoneyPrinterV2 Actually Does

    The core capabilities of MoneyPrinterV2 break down into several automated workflows:

    • Twitter Bot with CRON Scheduling: Automatically generates and posts tweets on a schedule using AI. Configure your topics, tone, and posting frequency, and the bot handles content creation and publication independently.
    • YouTube Shorts Automater: Takes a text prompt or article, generates a script using AI, creates a voiceover with KittenTTS, pairs it with relevant video clips or generated visuals, and exports a formatted short video ready for YouTube Shorts. CRON job support means you can queue batches for automatic upload.
    • Affiliate Marketing Module: Connects to Amazon’s affiliate program and Twitter to identify products, generate promotional content, and post affiliate links automatically.
    • Local Business Outreach: Finds local businesses and generates cold outreach campaigns — all AI-powered.

    Under the Hood

    MoneyPrinterV2 requires Python 3.12 and is designed for straightforward installation:

    git clone https://github.com/FujiwaraChoki/MoneyPrinterV2.git
    cd MoneyPrinterV2
    cp config.example.json config.json
    # Fill out your API keys and configuration in config.json
    python -m venv venv && source venv/bin/activate
    pip install -r requirements.txt
    python src/main.py

    Advanced users can also leverage shell scripts in the /scripts directory for direct CLI access to core functionality without the web interface.

    The Controversy

    MoneyPrinterV2 exists in a gray area that the open-source AI community has not fully grappled with. On one hand, it is a genuinely impressive piece of engineering — automating video creation, content scheduling, and affiliate linking using free AI models is technically non-trivial. On the other hand, it is explicitly designed to generate scale content for commercial purposes with minimal human oversight.

    The project’s own disclaimer states:

    “This project is for educational purposes only. The author will not be responsible for any misuse of the information provided.”

    This is the same boilerplate language used by most AI tools that could theoretically be misused — and like most such disclaimers, it raises more questions than it answers. The question of whether an automated content factory at this scale is “educational” is one the community will continue to debate.

    The Community Fork: MoneyPrinterTurbo

    One sign of MoneyPrinterV2’s popularity is the emergence of community forks. The most notable is MoneyPrinterTurbo, a Chinese-language version that has also gained significant traction. The proliferation of forks in multiple languages underscores the global demand for AI-powered content automation tools.

    What the Numbers Tell Us

    With nearly 25,000 stars in what appears to be a relatively short timeframe, MoneyPrinterV2 is among the fastest-growing open-source AI projects on GitHub. The combination of AI video generation, social media automation, and affiliate marketing in a single modular application addresses a real pain point for indie creators, digital marketers, and anyone looking to generate passive income through content — even if the ethics of that automation remain debatable.

    Whether you view it as a productivity breakthrough or a warning sign about AI-generated content flooding the internet, MoneyPrinterV2 is a project worth understanding. The code is open, the features are real, and its growth trajectory suggests it is filling a genuine market demand.

  • Project N.O.M.A.D: The Offline AI Survival Computer That’s Quietly Winning GitHub

    Project N.O.M.A.D: The Offline AI Survival Computer That’s Quietly Winning GitHub

    Imagine a computer that works without the internet — no cloud, no servers, no connectivity required — and is packed with everything you need to survive, learn, and make decisions when civilization’s digital infrastructure goes dark. That is exactly what Project N.O.M.A.D (Novel Offline Machine for Autonomous Defense) delivers, and it is turning heads on GitHub with over 14,800 stars and climbing fast.

    Developed by Crosstalk Solutions, N.O.M.A.D is a self-contained, offline-first knowledge and AI server that runs on any Debian-based system. It orchestrates a suite of containerized tools via Docker, and its crown jewel is a fully local AI chat powered by Ollama with semantic search capabilities through Qdrant — meaning your AI assistant never phones home.

    What N.O.M.A.D Actually Does

    Think of N.O.M.A.D as the ultimate digital survival kit. Once installed, it provides:

    • AI Chat with a Private Knowledge Base: Powered by Ollama and Qdrant, with document upload and RAG (Retrieval-Augmented Generation) support. Upload your own PDFs, manuals, or reference docs and query them conversationally — entirely offline.
    • Information Library: Offline Wikipedia, medical references, survival guides, and ebooks via Kiwix. This is essentially a compressed, searchable archive of human knowledge on your hard drive.
    • Education Platform: Kolibri delivers Khan Academy courses with full progress tracking and multi-user support. Perfect for classrooms in remote areas or anyone preparing for when the grid is down.
    • Offline Maps: Downloadable regional maps via ProtoMaps, searchable and navigable without a data connection.
    • Data Tools: Encryption, encoding, hashing, and analysis tools through CyberChef — all running locally.
    • Local Note-Taking: FlatNotes provides markdown-based note capture with full offline support.
    • Hardware Benchmarking: A built-in system benchmark with a community leaderboard so you can score your hardware against other N.O.M.A.D users.

    One Command to Rule Them All

    Installation is refreshingly simple. On any Ubuntu or Debian system:

    sudo apt-get update && sudo apt-get install -y curl && curl -fsSL https://raw.githubusercontent.com/Crosstalk-Solutions/project-nomad/refs/heads/main/install/install_nomad.sh -o install_nomad.sh && sudo bash install_nomad.sh

    Once running, access the Command Center at http://localhost:8080 from any browser. No desktop environment required — it is designed to run headless as a server.

    Why This Matters More Than You Think

    In an era of increasing digital centralization, N.O.M.A.D is a quiet act of resistance. It says: what if you could have the power of modern AI — language models, semantic search, curated knowledge — without surrendering your data to a third party? The AI chat does not route through OpenAI, Anthropic, or Google. It runs entirely on your hardware using Ollama, which supports a growing library of open-weight models like Llama 3, Mistral, and Phi.

    For journalists operating in repressive regimes, researchers in remote field locations, or simply privacy-conscious users who want a powerful AI assistant without the surveillance economy, N.O.M.A.D is a compelling answer. The project is actively maintained, has a Discord community, and the team has built a community benchmark site at benchmark.projectnomad.us.

    Hardware Requirements

    The core management application runs on modest hardware. But if you want the AI features — and most users will — the project recommends a GPU-backed machine to get the most out of Ollama. A modern laptop with 16GB RAM and an NVIDIA GPU will deliver a genuinely useful local AI experience, while a dedicated server with a powerful GPU becomes a formidable offline intelligence hub.

    The Bigger Picture

    What makes N.O.M.A.D genuinely interesting is not any single feature but the combination: it is one of the first projects that treats offline capability not as a limitation but as a design philosophy. Most “AI offline” tools are just stripped-down versions of their online counterparts. N.O.M.A.D is built from the ground up for disconnected operation, treating the absence of internet as a feature rather than a bug.

    With over 2,450 stars earned in a single day, the GitHub community is clearly paying attention. Whether you are preparing for the next natural disaster, building educational infrastructure in underserved areas, or simply want a privacy-respecting AI that never sleeps, Project N.O.M.A.D deserves a spot on your radar.

  • WiFi as a Sensor: How RuView Is Reinventing Human Sensing Without Cameras

    WiFi as a Sensor: How RuView Is Reinventing Human Sensing Without Cameras

    Imagine a technology that can detect human pose, monitor breathing rates, and sense heartbeats — all without a single camera, wearable device, or internet connection. That’s the promise of RuView, an open-source project built on Rust that’s turning commodity WiFi signals into a powerful real-time sensing platform.

    Developed by ruvnet and built on top of the RuVector library, RuView implements what researchers call “WiFi DensePose” — a technique that reconstructs human body position and movement by analyzing disturbances in WiFi Channel State Information (CSI) signals. The project has garnered over 41,000 GitHub stars, with more than 1,000 stars earned in a single day.

    How WiFi DensePose Works

    The technology exploits a fundamental physical property: human bodies disturb WiFi signals as they move through a space. When you walk through a room, your body absorbs, reflects, and scatters WiFi radio waves. By analyzing the Channel State Information — specifically the per-subcarrier amplitude and phase data — it’s possible to reconstruct where a person is standing, how they’re moving, and even physiological signals like breathing and heartbeat.

    Unlike research systems that rely on synchronized cameras for training data, RuView is designed to operate entirely from radio signals and self-learned embeddings at the edge. The system learns in proximity to the signals it observes, continuously improving its local model without requiring cameras, labeled datasets, or cloud infrastructure.

    Capabilities That Go Beyond Pose Estimation

    RuView’s capabilities are impressive and wide-ranging:

    • Pose Estimation: CSI subcarrier amplitude and phase data is processed into DensePose UV maps at speeds of up to 54,000 frames per second in pure Rust.
    • Breathing Detection: A bandpass filter (0.1–0.5 Hz) combined with FFT analysis detects breathing rates in the 6–30 breaths-per-minute range.
    • Heart Rate Monitoring: A bandpass filter (0.8–2.0 Hz) enables heart rate detection in the 40–120 BPM range — all without wearables.
    • Presence Sensing: RSSI variance combined with motion band power provides sub-millisecond latency presence detection.
    • Through-Wall Sensing: Using Fresnel zone geometry and multipath modeling, RuView can detect human presence up to 5 meters through walls.

    Runs on $1 Hardware

    Perhaps most remarkably, RuView runs entirely on inexpensive hardware. An ESP32 sensor mesh — with nodes costing as little as approximately $1 each — can be deployed to give any environment spatial awareness. These small programmable edge modules analyze signals locally and learn the RF signature of a room over time.

    The entire processing pipeline is built in Rust for maximum performance and memory safety. Docker images are available for quick deployment, and the project integrates with the Rust ecosystem via crates.io.

    Privacy by Design

    In an era of growing concerns about surveillance capitalism and camera proliferation, RuView offers a fundamentally different approach. No cameras means no pixel data. No internet means no cloud dependency. No wearables means nothing needs to be worn or charged. The system observes the physical world through the signals that already exist in any WiFi-equipped environment.

    This makes RuView particularly compelling for applications in elder care monitoring, baby monitors, smart building energy management, security systems, and healthcare settings where camera-based monitoring would be inappropriate or impractical.

    Getting Started

    To run RuView, you’ll need CSI-capable hardware — either an ESP32-S3 development board or a research-grade WiFi network interface card. Standard consumer WiFi adapters only provide RSSI data, which enables presence detection but not full pose estimation. The project documentation provides detailed hardware requirements and setup instructions.

    Docker deployment is straightforward:

    docker pull ruvnet/wifi-densepose:latest
    docker run -p 3000:3000 ruvnet/wifi-densepose:latest
    # Open http://localhost:3000

    RuView represents a fascinating convergence of machine learning, signal processing, and edge computing — all in an open-source package that’s changing what’s possible with commodity wireless hardware.

  • DeerFlow 2.0: ByteDance’s Open-Source SuperAgent Framework Takes GitHub by Storm

    DeerFlow 2.0: ByteDance’s Open-Source SuperAgent Framework Takes GitHub by Storm

    ByteDance, the Chinese tech giant best known for TikTok, has released what may be one of the most ambitious open-source AI agent frameworks to date: DeerFlow 2.0. Since its launch, the project has accumulated over 42,000 stars on GitHub, with more than 4,300 stars earned in a single day — a growth trajectory that has the entire machine learning community buzzing.

    DeerFlow 2.0 is described as an “open-source SuperAgent harness.” But what does that actually mean? In practical terms, it’s a framework that orchestrates multiple AI sub-agents working together in sandboxes to autonomously complete complex, multi-hour tasks — from deep research reports to functional web pages to AI-generated videos.

    From Deep Research to Full-Stack Super Agent

    The original DeerFlow launched in May 2025 as a focused deep-research framework. Version 2.0 is a ground-up rewrite on LangGraph 1.0 and LangChain that shares no code with its predecessor. ByteDance explicitly framed the release as a transition “from a Deep Research agent into a full-stack Super Agent.”

    The key architectural difference is that DeerFlow is not just a thin wrapper around a large language model. While many AI tools give a model access to a search API and call it an agent, DeerFlow 2.0 gives its agents an actual isolated computer environment: a Docker sandbox with a persistent, mountable filesystem.

    The system maintains both short- and long-term memory that builds user profiles across sessions. It loads modular “skills” — discrete workflows — on demand to keep context windows manageable. And when a task is too large for one agent, a lead agent decomposes it, spawns parallel sub-agents with isolated contexts, executes code and bash commands safely, and synthesizes the results into a finished deliverable.

    Key Features That Set DeerFlow 2.0 Apart

    DeerFlow 2.0 ships with a remarkable set of capabilities:

    • Docker-based AIO Sandbox: Every agent runs inside an isolated container with its own browser, shell, and persistent filesystem. This ensures that the agent’s operations remain strictly contained, even when executing bash commands or manipulating files.
    • Model-Agnostic Design: The framework works with any OpenAI-compatible API. While many users opt for cloud-based inference via OpenAI or Anthropic APIs, DeerFlow supports fully localized setups through Ollama, making it ideal for organizations with strict data sovereignty requirements.
    • Progressive Skill Loading: Modular skills are loaded on demand to keep context windows manageable, allowing the system to handle long-horizon tasks without performance degradation.
    • Kubernetes Support: For enterprise deployments, DeerFlow supports distributed execution across a private Kubernetes cluster.
    • IM Channel Integration: The framework can connect to external messaging platforms like Slack or Telegram without requiring a public IP.

    Real-World Capabilities

    Demos on the project’s official website (deerflow.tech) showcase real outputs: agent-generated trend forecast reports, videos generated from literary prompts, comics explaining machine learning concepts, data analysis notebooks, and podcast summaries. The framework is designed for tasks that take minutes to hours to complete — the kind of work that currently requires a human analyst or a paid subscription to a specialized AI service.

    ByteDance specifically recommends using Doubao-Seed-2.0-Code, DeepSeek v3.2, and Kimi 2.5 to run DeerFlow, though the model-agnostic design means enterprises aren’t locked into any particular provider.

    Enterprise Readiness and the Safety Question

    One of the most pressing questions for enterprise adoption is safety and readiness. While the MIT license is enterprise-friendly, organizations need to evaluate whether DeerFlow 2.0 is production-ready for their specific use cases. The Docker sandbox provides functional isolation, but organizations with strict compliance requirements should carefully evaluate the deployment architecture.

    ByteDance offers a bifurcated deployment strategy: the core harness can run directly on a local machine, across a private Kubernetes cluster, or connect to external messaging platforms — all without requiring a public IP. This flexibility allows organizations to tailor the system to their specific security posture.

    The Open Source AI Agent Race

    DeerFlow 2.0 enters an increasingly crowded field. Its approach of combining sandboxed execution, memory management, and multi-agent orchestration is similar to what NanoClaw (an OpenClaw variant) is pursuing with its Docker-based enterprise sandbox offering. But DeerFlow’s permissive MIT license and the backing of a major tech company give it a unique position in the market.

    The framework’s rapid adoption — over 39,000 stars within a month of launch and 4,600 forks — signals strong community interest in production-grade open-source agent frameworks. For developers and enterprises looking to build sophisticated AI workflows without vendor lock-in, DeerFlow 2.0 is definitely worth watching.

    The project is available now on GitHub under the MIT License.

  • Nvidia’s Nemotron-Cascade 2: How a 3B Parameter Model Wins Gold Medals in Math and Coding

    Nvidia’s Nemotron-Cascade 2: How a 3B Parameter Model Wins Gold Medals in Math and Coding

    The prevailing assumption in AI development has been straightforward: larger models trained on more data produce better results. Nvidia’s latest release directly challenges that orthodoxy鈥攁nd the training recipe behind it may matter more to enterprise AI teams than the model itself.

    Nemotron-Cascade 2 is an open-weight 30B Mixture-of-Experts model that activates only 3B parameters at inference time. Despite this compact footprint, it achieved gold medal-level performance on three of the world’s most demanding competitions: the 2025 International Mathematical Olympiad, the International Olympiad in Informatics, and the ICPC World Finals. It is only the second open model to reach this tier, after DeepSeek-V3.2-Speciale鈥攁 model with 20 times more parameters.

    Nvidia Nemotron-Cascade 2 Performance

    The Post-Training Revolution

    Pre-training a large language model from scratch is enormously expensive鈥攐n the order of tens to possibly hundreds of millions of dollars for frontier models. Nemotron-Cascade 2 starts from the same base model as Nvidia’s existing Nemotron-3-Nano鈥攜et it outperforms that model on nearly every benchmark, often surpassing Nvidia’s own Nemotron-3-Super, a model with four times the active parameters.

    The difference is entirely in the post-training recipe. This is the strategic insight for enterprise teams: you don’t necessarily need a bigger or more expensive base model. You may need a better training pipeline on top of the one you already have.

    Cascade RL: Sequential Domain Training

    Reinforcement learning has become the dominant technique for teaching LLMs to reason. The challenge is that training a model on multiple domains simultaneously鈥攎ath, code, instruction-following, agentic tasks鈥攐ften causes interference. Improving performance in one domain degrades it in another, a phenomenon known as catastrophic forgetting.

    Cascade RL addresses this by training RL stages sequentially, one domain at a time, rather than mixing everything together. Nemotron-Cascade 2 follows a specific ordering: first instruction-following RL, then multi-domain RL, then on-policy distillation, then RLHF for human preference alignment, then long-context RL, then code RL, and finally software engineering RL.

    MOPD: Reusing Your Own Training Checkpoints

    Even with careful sequential ordering, some performance drift is inevitable as the model passes through many RL stages. Nvidia’s solution is Multi-Domain On-Policy Distillation鈥攁 technique that selects the best intermediate checkpoint for each domain and uses it as a “teacher” to distill knowledge back into the student model.

    Critically, these teachers come from the same training run, sharing the same tokenizer and architecture. This eliminates distribution mismatch problems that arise when distilling from a completely different model family. According to Nvidia’s technical report, MOPD recovered teacher-level performance within 30 optimization steps on the AIME 2025 math benchmark, while standard GRPO required more steps to achieve a lower score.

    What Enterprise Teams Can Apply

    Several design patterns from this work are directly applicable to enterprise post-training efforts. The sequential domain ordering in Cascade RL means teams can add new capabilities without rebuilding the entire pipeline鈥攁 critical property for organizations that need to iterate quickly. MOPD’s approach of using intermediate checkpoints as domain-specific teachers eliminates the need for expensive external teacher models.

    Nemotron-Cascade 2 is part of a broader trend toward “intelligence density”鈥攅xtracting maximum capability per active parameter. For enterprise deployment, this matters enormously. A model with 3B active parameters can be served at a fraction of the cost and latency of a dense 70B model. Nvidia’s results suggest that post-training techniques can close the performance gap on targeted domains, giving organizations a path to deploy strong reasoning capabilities without frontier-level infrastructure costs.

    For teams building systems that need deep reasoning on structured problems鈥攆inancial modeling, scientific computing, software engineering, compliance analysis鈥擭vidia’s technical report offers one of the more detailed post-training methodologies published to date. The model and its training recipe are now available for download, giving enterprise AI teams a concrete foundation for building domain-specific reasoning systems without starting from scratch.
