LOC·0724k token route ~25 GB RAM dense core LRU cache 744B experts · on disk streamed on demand

Colibrì

A pure-C, zero-dependency inference engine that runs frontier Mixture-of-Experts models — like GLM-5.2's 744B — on hardware you already own. It keeps the dense core in RAM and streams experts from disk on demand, treating VRAM, RAM and storage as one tiered memory. It even serves an Anthropic-compatible API, so Claude Code talks to it directly.

AGT·1025k lead sub sub sub steps

DeepAgents

Scaffolding for long-horizon agents that plan, spin up sub-agents, and keep working across many steps.

Built my own deep agent without LangChain, but their tutorial is a nice starting point.

Great integration into langchain ecosystem, native langsmith support. But is rather slow latency wise, therefore weak for interactive agents. Switching to omp as a coding agent for example here resulted in less scaffolding and faster runtimes of the coding agent.
AGT·154.0k agent/ instructions.mdtools/skills/channels/schedules/ run state on disk resume

Eve

A filesystem-first framework for durable agents from Vercel. You author an agent as plain files — instructions, typed tools, skills, channels, schedules — and it persists its own state to disk, so runs survive restarts and move between environments.

Nice abstraction for durable agents, and TS tool definitions with type safety make it easy for an agent to write its own tools. Downside — like a lot of Vercel's stuff — is the tight coupling to their infra.
INF·2030k your app one call LiteLLM gateway OpenAI Claude Bedrock local spend tracked

LiteLLM

One OpenAI-compatible interface to 100+ model providers. Swap or load-balance across OpenAI, Anthropic, Bedrock, Vertex, and local models without changing your code — and run it as a proxy that tracks spend, sets budgets, and manages keys.

Easy to setup, great to manage llm endpoints from different providers. Nice for first level tracing/observability (tracking costs and budget of deparments for example) or token cost optimisation via headroom as u set it up once and it works for the whole company.
AGT·25 $ omp plan mode LSPDAPmemory sub

omp (Oh My Pi)

A terminal coding agent with the IDE wired in — language-server and debugger access (LSP/DAP), subagents, plan mode, and hindsight memory, driven by a native Rust engine. Aims to give a CLI agent the context a real IDE has.

we used this instead of deepagents at a client. It is generally more efficient, faster, better compaction or context management. Generally superseeds deepagents. There are two ways to use it! Either use it as claude code as your coding harness, or call it via omp -rpc for the autonomouses mode It works with the claude subscription, but anthropics past showed that they ban people for that as its against their tos
DEV·30336 PR diff revrevrev critical important suggestion inline comments

PR-AF

An open-source agentic PR reviewer that builds a custom review strategy per pull request — spawning parallel reviewer agents, grounding every finding in the actual code via AST extraction, and challenging its own findings before posting inline comments. A deep, CI-gating alternative to CodeRabbit.

Open-source project that apparently supersedes CodeRabbit for code reviews.
