GPT 5 Nano is a language model developed by OpenAI. It's particularly well-suited for analyzing images, screenshots, and visual content, tackling complex, multi-step reasoning problems, orchestrating tool-using agents that call APIs and external services, producing structured outputs for reliable data extraction and handling large contexts of up to 400K tokens. Its 400K-token context window means you can pass in entire documents, codebases, or conversation histories without losing context. It can write up to 128K tokens in a single response.
As of Nov 4, 2026, GPT 5 Nano costs $0.0088 per 1M input tokens and $0.071 per 1M output tokens on Qubax, versus $0.025 / $0.200 on OpenRouter (65% less on input). A typical 1,000 chat requests (2K tokens in, 500 out) come to about $0.05. Measured availability over the last 7 days: 100.0%. 51 independent compute providers currently serve it, so requests fail over automatically. It handled 447 requests on Qubax in the last 24 hours. Pay with USDC, USDT, BTC, ETH or 350+ other coins — no credit card required.
