## How do I call gpt-oss-20b?

With the OpenAI SDK, as for any OpenAI-compatible API: set the base URL to `https://llmwithcrypto.com/api/v1`, read your key from `LLMWITHCRYPTO_API_KEY`, and pass `gpt-oss-20b` as the model. Pass your API key as a Bearer token in the Authorization header, as the OpenAI SDK does.

*gpt_oss_20b.py*

```python
import os

from openai import OpenAI

client = OpenAI(
    base_url="https://llmwithcrypto.com/api/v1",
    api_key=os.environ["LLMWITHCRYPTO_API_KEY"],
)

resp = client.chat.completions.create(
    model="gpt-oss-20b",
    messages=[{"role": "user", "content": "Extract the invoice number, date and total from this email as JSON."}],
)
print(resp.choices[0].message.content)
print(resp.usage)  # prompt_tokens and completion_tokens: what the call costs

```

## What is gpt-oss-20b good for?

gpt-oss-20b is the smaller of OpenAI’s two open-weight models, Apache 2.0, with a context of about 128K tokens. Only two of the hosts we read listed it on a public price page, so its median rests on fewer prices than most.

It fits small, frequent jobs where cost and speed matter most: extraction, routing, short answers and simple tool calls. For harder reasoning, [gpt-oss-120b](https://llmwithcrypto.com/models/gpt-oss-120b/) is the larger sibling on the same key.

## What licence does gpt-oss-20b come with?

Apache 2.0 with OpenAI’s short usage policy (comply with applicable law), the same terms as gpt-oss-120b. Serving it as an API is allowed. Each model keeps its own licence and use policy (for example Meta’s Llama Acceptable Use Policy and the “Built with Llama” notice); using a model through us means accepting them.

## gpt-oss-20b questions

### Why only two hosts in the comparison?

On 23 October 2026, DeepInfra and Parasail were the only hosts we read that showed gpt-oss-20b on a public price page; the others did not list it, offered it for fine-tuning only, or had no readable price page.

### Can I switch between gpt-oss-20b and 120b?

Yes, by changing the `model` field. Both run on the same endpoint and key, and each call is charged at the price of the model it used.

### Is anything stored?

We do not store your prompts or the model’s answers: once a response is sent, its text is gone. Each call leaves one log line with the time, the account, the model and the token counts, deleted after 30 days.
