GPT-4o is a language model developed by OpenAI. It's particularly well-suited for analyzing images, screenshots, and visual content, orchestrating tool-using agents that call APIs and external services, grounding responses in real-time web search results, producing structured outputs for reliable data extraction 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 16K tokens in a single response.
As of Nov 4, 2026, GPT-4o costs $0.223 per 1M input tokens and $0.893 per 1M output tokens on Qubax, versus $2.50 / $10.00 on OpenRouter (91% less on input). A typical 1,000 chat requests (2K tokens in, 500 out) come to about $0.89. Measured availability over the last 7 days: 100.0%. 237 independent compute providers currently serve it, so requests fail over automatically. It handled 2,060 requests on Qubax in the last 24 hours.
