AI inference deals
Hosted model APIs, recurring free capacity, and inference credits. These stay first because limits and model availability change quickly.
Free Tier
Hetzner
Verified
Free experimental OpenAI-compatible inference
Hetzner's no-cost experimental OpenAI-compatible inference API now documents Qwen3.8-27B alongside Qwen/Qwen3.6-35B-A3B-FP8. This is a meaningful model-catalog expansion to the already-known Hetzner experiment; availability is not guaranteed and the service should not be used for production.
Value
Free hosted inference during experimental status; two documented vision-capable models with 262,144-token context
Who qualifies
Hetzner customers with access to the Experiments platform who create an inference API token
Expiry
not stated; free while the Inference API remains experimental

Free-model router and zero-cost model variants
OpenRouter publishes a `openrouter/free` router that automatically picks a random free model from those matching the request's capabilities, giving zero-cost inference with one model string.
Value
Free router (`openrouter/free`) auto-selects from 20+ zero-cost models; no API key charges, no credit card; typical free-model limits around 20 requests/minute and 200 requests/day (per OpenRouter docs/community listings).
