Chimera: an open-source, self-hostable agent that runs on local models (any OpenAI-compatible endpoint) and can fuse several at once
I've been building an open-source agent (Apache-2.0) and wanted to share it here because it's designed to be fully local and self-hostable: it talks to any OpenAI-compatible endpoint, so Ollama / llama.cpp / vLLM / LM Studio all work as the backend. No cloud lock-in, your keys and data stay yours.
The core idea is LLM-Fusion: for the hard steps it can run a panel of models on the same prompt, have a judge model cross-check them (consensus / contradictions / blind spots), and a synthesizer write the final answer. Locally this is fun because you can mix a few small local models and let them cross-check each other. A cost/latency-aware router keeps easy turns on a single model so you're not paying panel latency for everything.
Beyond that it's a full agent: plan -> act -> verify-or-revert (it runs your tests and treats the result as ground truth), layered memory (SQLite + FTS recall, cross-session profile, consolidation), a governance kernel, cron/proactive jobs, MCP client + OpenAPI-to-tool import, and an isolated subagent/crew layer (parallel git worktrees with per-worker verify gates). Runs on a laptop or a $5 VPS via Docker.
Honest status: it's alpha - 463 tests, mypy --strict clean, but no production mileage yet. Local reasoning quality obviously depends on the models you point it at, so I'd genuinely love to hear which local models people find good enough to actually drive an agent loop (reliable tool use + self-correction) - that's the make-or-break for going fully local.
