Paid Plans
Starter, Pro, and Enterprise plans unlock all models. The only difference between paid tiers is per-service monthly call limits (see Credits & Rate Limits).
Paid-only models include: kimi-k2.5-fast (currently under maintenance), openai/gpt-5.4, openai/gpt-5.4-mini, openai/gpt-5.4-pro, openai/gpt-5.4-nano, anthropic/claude-opus-4.6, anthropic/claude-sonnet-4.6, google/gemini-3.1-pro-preview, google/gemini-3-flash-preview, google/gemini-3.1-flash-lite, google/gemini-3.1-flash-lite, x-ai/grok-4.20, qwen/qwen3.5-plus, qwen/qwen3.5-flash, and mistralai/mistral-small-2603. Note: the free-tier auto-router is exposed as auto (not openrouter/auto) and IS available on the free plan.
Error Handling
When a free-plan user calls a paid-only model, the API returns:
{
"error": {
"message": "Model 'openai/gpt-5.4' requires a paid plan. See GET /api/v1/models/access for the full list of free-plan models. Upgrade at https://app.callmissed.com/pricing",
"type": "invalid_request_error",
"code": "model_not_available"
}
}HTTP status: 403. Check the code field for model_not_available to handle this programmatically.
