GPT OSS 120B is a language model developed by OpenAI. It's particularly well-suited for tackling complex, multi-step reasoning problems and handling large contexts of up to 128K tokens. Its 128K-token context window means you can pass in entire documents, codebases, or conversation histories without losing context. It can write up to 33K tokens in a single response.
As of Nov 4, 2026, GPT OSS 120B costs $0.097 per 1M input tokens and $0.487 per 1M output tokens on Qubax, versus $0.130 / $0.650 on OpenRouter (25% less on input). A typical 1,000 chat requests (2K tokens in, 500 out) come to about $0.44. 24 independent compute providers currently serve it, so requests fail over automatically. It handled 100 requests on Qubax in the last 24 hours. Pay with USDC, USDT, BTC, ETH or 350+ other coins — no credit card required.
