About
Hetzner's experimental inference API is one of the most generous free inference endpoints anywhere: OpenAI-compatible, serving Qwen3.6-35B with a 262k context window and vision support, with limits of 500M input and 5M output tokens per day. It is free while experimental with just a Hetzner account (no credit card), but there is no SLA and it is not for production. Perfect for prototyping agents and running free-tier coding agents at real scale.
