- Free allowance
- Free of charge while the Inference API remains in experimental status; two models, Qwen/Qwen3.6-35B-A3B-FP8 and Qwen3.8-27B, each with a 262,144-token context and text plus image input; limits per API key are 4M input tokens and 100k output tokens per 60 s and 10 requests per 60 s

| Free tier | free of charge while the Inference API remains in experimental status; two models, Qwen/Qwen3.6-35B-A3B-FP8 and Qwen3.8-27B, each with a 262,144-token context and text plus image input; limits per API key are 4M input tokens and 100k output tokens per 60 s and 10 requests per 60 s unit tokens; metered on request-count; the vendor says it will email users before the experimental status changes; the model list changes during the experiment and GET /v1/models is definitive |

| Limits | - request-rate (binding) per API key: 10 requests per 60 s, 4M input tokens per 60 s, 100k output tokens per 60 s; HTTP 429 beyond any of them source
|
|---|
| Binding | request-rate 10 requests per 60 s per key is the ceiling that decides throughput; the token windows are far above it |
|---|
| Identity | card a token is created after logging in to a Hetzner account at experiments.hetzner.com; the vendor's account sign-up needs an email address, contact information and a billing address, with a phone number optional. Whether a card or an ID check is required before a token can be created is unverified: behind a sign-up. One third-party write-up reports a credit card is required |

| Composes with | Hetzner-hosted open-weight models behind a per-key ceiling of 10 requests per minute |
|---|
| Reliability | experimental service offered as is: performance and availability are not guaranteed, no backups, and the model list can change without a fixed schedule |
|---|
| Notes | the identity requirement is the open item: the kind is recorded as card because a third-party write-up says a credit card must be added before a token can be generated, and a second third-party page says payment verification can include a card charge; the vendor's account page lists an email address, contact information and a billing address with a phone number optional, and the key-minting page was not captured |
|---|
| Evidence note | reported the rate limits and the free status are quoted from the vendor's docs page; the identity requirement is a third-party report because the key-minting page is a client-rendered application that could not be captured as text. |
