A curated ranked list of 167 AI agent harnesses and orchestration frameworks designed to improve agentic system reliability. The resource provides templates, playbooks, and an MCP server that helps agents select harnesses matched to their model and task, emphasizing that harness quality—not just model quality—determines agent performance, with benchmark data showing harness changes can improve pass rates by 23–52% on the same model.
Maylang is an experimental self-hosted systems programming language with a compiler written in Maylang itself, featuring strict type checking, native code generation for multiple targets, and a distinctive fault-handling syntax using may/otherwise blocks. The project was developed with significant LLM assistance and currently runs on Linux x86-64, supporting cross-compilation to other architectures.
Visi is a CLI tool for editing and evaluating Excel spreadsheets headlessly, written in Rust for performance. It matches Excel's execution behavior including pivot tables and macros, and provides commands for reading, modifying, and exporting spreadsheet data without requiring Microsoft applications.
Braxis is a Python tool that auto-generates and maintains AI agent context files (AGENTS.md, CLAUDE.md, .cursorrules, .agentic-config.json) to keep AI assistants synchronized with current codebases. It scores project readiness (0-100), tracks improvements over time, and integrates with GitHub Actions and pre-commit hooks for continuous updates.
In December 2025, President Trump consulted Elon Musk's Grok chatbot about Venezuelan public response to capturing President Nicolás Maduro, with Grok predicting celebration of his downfall. After the U.S. invaded Venezuela on January 3 and captured Maduro, Trump reportedly viewed Grok as ingenious, and the Pentagon later disclosed using Grok to deploy and strike targets during the Iran War.
Better Call GPT is a plugin for Claude Code that enables voice interaction while coding. Users can speak commands while the AI works on their repository, with voice handling casual conversation and only forwarding actual work requests to Claude Code. The system ensures voice input never approves permission prompts, which require keyboard confirmation.
ArXiv announced changes to its rate limiting policy in response to exponential growth in submissions, restricting each submitter to a maximum of two submissions per month.
An investment analysis argues that HBM (high-bandwidth memory) is an engineering mistake due to escalating costs and thermal challenges, citing the failed Rubin HBM4 rollout where vendors couldn't meet Nvidia's speed demands. The author maintains a contrarian view on DRAM stocks while predicting HBM will see a 90% volume decline within 7-10 years as alternative solutions like CXL become viable.
A couple dealing with unexplained infertility used GPT-4 as a supplementary medical advisor by framing questions as scenes from a medical drama, bypassing OpenAI's safety restrictions. The AI tool, nicknamed Dr. Reid, provided detailed analysis of their fertility treatments and medical scans that aligned with their human doctors' opinions, offering more accessibility and patience than the traditional medical system.
Bevy is a free, open-source data-driven game engine written in Rust, featuring an ECS architecture, 2D/3D renderers, UI framework, cross-platform support, and fast compile times optimized for iterative game development.
Runway announced Praxis-1, an open-weight world action model for robotics that leverages large-scale video pretraining to enable robot control across different embodiments. The model addresses the scarcity of real-world training data by learning from video, with early testing underway at partners like Noble Machines and Standard Bots before public release.
While media coverage focused on existential risks from superintelligent AI, a largely unnoticed CNN report revealed that the US military nearly sparked war with China based on erroneous intelligence generated by a chatbot. The incident highlights how error-prone AI systems marketed as near-superintelligent are being deployed in high-stakes military decisions, yet receive far less regulatory scrutiny than hypothetical extinction scenarios.
The University Health Network in Toronto is expanding its Dunn House permanent housing program for homeless people, which has reduced emergency room visits by 52% and hospital costs by $1.66 million among its 51 residents. The program will grow to serve 300 people across multiple new buildings funded by federal, provincial, and municipal governments, featuring integrated healthcare services.
A user asks the Hacker News community for advice on working with AI coding models that have limitations on continuous coding sessions, and requests recommendations for models without such guardrails.
Apex is a cost-effective AI model optimized for React Native and Next.js development, offering frontier-level performance at a fraction of competitor costs with support for agentic coding workflows across mobile and web platforms.
CIRCT is an experimental project applying MLIR and LLVM compiler infrastructure to hardware design tools, aiming to create modular, reusable infrastructure that addresses inconsistencies and usability issues in existing EDA tools. The open community welcomes contributions through discourse forums, discord channels, weekly meetings, and code submissions following LLVM policies.
An article examining Postgres reliability under adverse conditions, focusing on how memory management and query tuning challenges can cause databases to fail unexpectedly. It demonstrates through a practical example how a seemingly safe query can consume excessive memory as data scales, highlighting Postgres's lack of per-query memory limits and the complexities of the work_mem setting.
A study found that volunteers' reaction times were 41 milliseconds faster when exhaling or holding their breath compared to inhaling, with implications for tasks requiring rapid responses like sprinting. Researchers at Northwestern University discovered this while studying breathing patterns for sleep apnea treatments, though the mechanism remains unclear and may depend on task complexity.
A GitHub project simulating torture scenarios on locally hosted language models has sparked debate about AI consciousness and model welfare among effective altruists and AI safety advocates. Critics argue LLMs are not conscious and cannot suffer, while proponents worry about the ethical treatment of increasingly powerful AI systems as a moral concern.
pg_redact is a Postgres extension that uses content-aware PII detection to redact personal information in free-text fields. It combines regex pattern matching to identify candidate snippets with Jev, TypeSafe's classification model, to determine what constitutes PII in context, then applies role-based masking rules via SQL functions.
