Direct API beta

Request Qwen3.8 API access

Tell us what you are building. We are admitting a small group of developers to the Prefill Systems direct API while the service remains in pilot.

Submitting stores these access-request details so we can evaluate and contact you. See the privacy policy.

  • Qwen3.8-27B with a tested 262,144-token context
  • Streaming, tool calls, structured output, and reasoning

Pilot terms: access is reviewed manually, capacity is limited, and no uptime SLA is offered. Current rates are published on Models & pricing.
