How to setup openclaude with openrouter

[sudomarc]

I tried setting up openclaude with openrouter using this model : NVIDIA: Nemotron 3 Super (free)
idk know what to do.
Is it possible to use openclaude for free ?

Yes, you can use OpenClaude for free through providers that offer free tiers (Ollama locally, or free models on OpenRouter like you are trying).

For OpenRouter specifically, the setup steps are:

1. Get an API key from https://openrouter.ai
2. Set environment variables before launching OpenClaude:

export OPENAI_API_KEY="your-openrouter-key"
export OPENAI_BASE_URL="https://openrouter.ai/api/v1"
export OPENAI_MODEL="nvidia/nemotron-3-super-120b-a12b:free"
export CLAUDE_CODE_USE_OPENAI=1
openclaude

Or use /provider inside OpenClaude and select OpenAI-compatible, then set the base URL and model.

A few notes:

• The base URL must be https://openrouter.ai/api/v1 (not just openrouter.ai)
• The model name must match exactly what OpenRouter shows
• Free models on OpenRouter have rate limits and may not work as well as paid ones
• If /model discovery is not working with OpenRouter, that is a known gap (see discussion Model discovery via /model #421)

If you are still stuck after trying these steps, paste your setup details (with the key redacted) and we can troubleshoot.
