Apache Burr: Open-Source State Machine Framework for Building Reliable AI Agents
Hacker News (AI keywords)4 days agoNew ToolApache Burr provides a state-machine-based architecture for building reliable AI agents, making complex multi-step LLM workflows predictable and testable. It includes built-in tracing, observability, and a local visualization UI, allowing developers to replay and debug agent execution step by step. Model-agnostic and integrable with LangChain, LlamaIndex, and major LLM providers, it also supports state persistence and human-in-the-loop workflows for production use.
Introducing FrontierCode★ 78
Hacker News (AI keywords)5 days agoBenchmarkCognition launched FrontierCode, a coding benchmark focused on mergeability rather than only functional correctness. It evaluates correctness, tests, scope discipline, style, and repository-specific quality standards. Built with open-source maintainers and extensive quality control, it shows current frontier models still struggle: Claude Opus 4.8 scores 13.4% on the hardest Diamond subset, ahead of GPT-5.5 and Gemini 3.1 Pro.
OpenEnv coordination expands to HF, PyTorch, Unsloth, Modal, and more
r/LocalLLaMA top day6 days agoNew ToolOpenEnv is a tool for creating agentic execution environments such as terminals, browsers, or other systems an agent can interact with. The project will now be coordinated by a committee including Meta-PyTorch, Reflection, Unsloth, Modal, Prime Intellect, Nvidia, Mercor, Fleet AI, and Hugging Face. The post also lists many AI organizations supporting or adopting OpenEnv, positioning it as infrastructure for open-source agent training.
Show HN: Paseo - Beautiful open-source coding agent interface
Hacker News (AI keywords)11 days agoNew ToolPaseo provides one interface for tools such as Claude Code, Codex, Copilot, OpenCode, and Pi. It runs agents through a local daemon on the user's own machine and supports desktop, mobile, web, and CLI clients. Its appeal is multi-agent orchestration and cross-device control, though real adoption depends on workflow fit, security, and reliability.
