Is there an response length limit for the inference API?

Hugging Face's Inference API returns only 2-3 sentences per response regardless of the model used, according to a user report. The issue may be resolved by setting the `max_new_tokens` parameter higher, ensuring the model supports long-form generation, and checking the context window limits.

Is there an response length limit for the inference API?

Hi, I am testing the Inference API with different models to rewrite texts. But no matter which model I choose, only about 2 - 3 sentences are returned as response. How can this be adjusted?

A few things to check:

Make sure you’re setting max_new_tokens

(or the equivalent generation parameter) high enough. The default value can be quite small.

Verify that the model you’re using supports long-form text generation.

Check whether your input plus output exceeds the model’s context window.

If you’re using the Inference API, inspect the full response to see if it indicates the generation stopped because it reached a token limit (finish_reason or similar).

If you can share the model name and your request payload, it will be easier to identify the cause.
