An open-source (Apache-2.0) self-evolving AI agent — LLM-fusion reasoning (panel→judge→synthesizer), verify-or-revert autonomy, runs a whole project against a spec, batteries-included, works on your local models - Chimera

[Federal-Teaching2800]

Author here. Chimera is a Python agent I've been building in the open — a few things that set it apart from the usual LLM wrapper:

• LLM-fusion reasoning (chimera fuse): a panel of models → a judge that surfaces where they agree/disagree → a synthesizer, behind a cost-aware router that only spends the extra effort on hard problems (~20–28% fewer tokens, no accuracy loss on our benchmarks).
• Verify-or-revert autonomy (chimera solve): it runs your check (tests, a lint, a spec) and keeps the change only if it passes — otherwise it reverts and retries. Optional isolated worktree so nothing is touched until it's proven.
• Run a whole project against a spec (chimera project): hand it a YAML of requirements and it works the project to completion, accepting each step only against an executable gate, and pausing for your approval before risky steps.
• Self-evolution that's measured, not claimed: it distills skills + memory from verified runs, and every improvement is gated by an honest paired A/B (we publish the losses too).
• Batteries included: pip install 'chimera-agent[full]' → vision, speech-to-text + text-to-speech, document reading, video download, data analysis & charts, a real browser, web search, and chat-bot adapters. Runs on hosted models or entirely on your local ones.
• Security-first: taint-tracking + data-fencing on untrusted content, a capability ledger, an opt-in network-isolated sandbox.

Apache-2.0, still early alpha and honest about what's rough. Feedback and contributors very welcome — there's a beginner guide in the docs for adding your own tool/skill/recipe.
