gpt-oss-120b has a context window of 128K tokens, with a maximum output of 33K tokens per response. That's roughly 171 words of input you can fit in a single prompt.
How does gpt-oss-120b perform on benchmarks?
gpt-oss-120b scores 93.4% on Math Index, 93.4% on AIME 2025, 87.8% on LiveCodeBench. See the full benchmark chart above for results across MMLU Pro, GPQA Diamond, SWE-Bench Verified, HumanEval, MATH, AIME, MMMU, and LiveBench.
What can gpt-oss-120b do?
gpt-oss-120b is a text-generation model you can call through any OpenAI-compatible client by pointing base_url to Requesty.
How do I use gpt-oss-120b with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "scaleway/gpt-oss-120b". The Quickstart above shows Python, JavaScript and cURL snippets.
Can I run gpt-oss-120b through Requesty?
Yes. gpt-oss-120b runs through Requesty's OpenAI-compatible API, served from Scaleway SAS. You do not host the model yourself: point base_url at Requesty, set the model to "scaleway/gpt-oss-120b", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
