NemoCode

NemoCode is a local relay that connects the coding agents you already run — Claude Code, Codex CLI, OpenCode, and Pi Code — to NVIDIA Nemotron and other open models on Nebius Token Factory, with live Tavily web search, short commands, and zero edits to your real tool config.

**Install once, launch anything.** One command drops `nemo` plus the short launchers `claudemo`, `codemo`, `opencodemo`, and `pimo` onto your PATH, installing Bun if you don't already have it:

```
curl -fsSL https://nemocode.org/install.sh | sh
```

`nemo configure` then asks for your Nebius Token Factory key and an optional Tavily key for live web search. Type `claudemo` or `codemo` and keep working.

**How it routes.** Each harness gets the treatment it needs: Claude Code goes through a local Anthropic-to-Nebius translation proxy, Codex CLI through a Responses-to-chat proxy with headless `exec` support and sessions that stay resumable across providers, while OpenCode and Pi Code get Nebius injected as an OpenAI-compatible provider for that run only. Nothing is written to your real agent config — close the session and your setup is exactly as it was.

**The models.** Nemotron is NVIDIA's family of open-weight models tuned for reasoning, tool use, and agentic coding, with a reasoning mode you can toggle per turn: trivial turns stay fast, hard ones go deep. Cosmos 3 Super Reasoner adds vision, so screenshots, diagrams, and spatial layouts have somewhere to go even when your primary model is text-only. The default for Claude Code and Codex is Nemotron 3 Ultra 550B, with Nemotron 3 Super and Nano available for mid-tier and cheap background turns.

The catalogue is fetched live from Nebius (`GET /v1/models?verbose=true`) at startup and cached locally, with each model's vision support read from the API rather than a hand-maintained list, so every served model is one flag away. The flag goes *before* the harness — `nemo --model nvidia/Cosmos3-Super-Reasoner codex exec "task"` — because the short aliases expand to `nemo <harness>` and a flag placed after the harness name is passed through to the agent and silently dropped.

**Also in the box:** Tavily-backed `web_search` emulation that streams real Anthropic citation blocks into the agent, per-session cost tracking metered against each model's real per-token rates and printed as a running total on exit, and a self-updating binary. Every token is served from Nebius Token Factory's SOC 2-compliant EU data centers, with zero data retention supported.
