Frequently asked questions

How much does gpt-oss-20b cost?

gpt-oss-20b costs $0.029 per 1M input tokens and $0.140 per 1M output tokens, sourced from openrouter. Cache reads, audio tokens and >200K-context tiers (where applicable) are listed in the Pricing detail block above.

What is the context window of gpt-oss-20b?

gpt-oss-20b has a context window of 128K tokens, with a max output of 16K tokens per reply. This is the total combined size of prompt + completion.

Does gpt-oss-20b support tool calling?

Yes. gpt-oss-20b supports tool calling (function calling). This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.

Does gpt-oss-20b support structured output / JSON mode?

Yes. gpt-oss-20b supports structured output / JSON-schema-constrained decoding. This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.

Can gpt-oss-20b accept image input?

No. gpt-oss-20b only accepts text as input. If you need image input, see our /capabilities/vision list for current vision-capable models.

Is gpt-oss-20b open-weight?

No. gpt-oss-20b is a proprietary model — only OpenAI (and any approved hosting partners) can serve it. The pricing above reflects the cheapest API access.

What are the best alternatives to gpt-oss-20b?

If gpt-oss-20b doesn't fit, consider gpt-oss-120b, GPT-5.4, GPT-5.2. Each one targets the same use case — see the Related links below for direct head-to-head pages.

Where does this data come from?

All numbers are normalised into a single canonical model record and reconciled with each provider's official documentation. We re-pull daily and write any changes (price, context, capability) to the /changelog page.
