Qubax uses an OpenAI-compatible API format. If you're using Anthropic's SDK directly, you can switch to the OpenAI SDK pointing at api.qubax.ai/v1, or use any OpenAI-compatible client. Claude model names remain the same.
Claude Opus 5 costs $6.40/1M input and $32.00/1M output on Qubax, compared to $10.00/$50.00 direct from Anthropic. That's 36% off — and the savings scale with usage.
