Free Tier Pricing & Limits

Rate Limit

Requests per minute

5 Requests per minute per account on most *-free routes

Daily Quota

Requests per day

100 requests/day and 1 000 000 tokens/day per account (500 Requests per day on somee.g. glm-4.7-flash-freecoding-minimax-m3-free)

Use Cases

Free coding-agent backend (Claude Code or Codex through the gateway)

trying several frontier open models with one key

Limitations & Considerations

Strict per-account caps (5 RPM, 100 RPD, 1M tokens/day)

free routes come and go (e.g. qwen3.6-plus-preview-free has been removed)

the ":free" Llama/Mistral ids are not zero-priced (0.02 ratio), so use the "-free" suffixed ids
