GPT-5.6 Terra is a multimodal 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, grounding responses in real-time web search results, producing structured outputs for reliable data extraction and handling large contexts of up to 1.1M tokens. Its 1.1M-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-5.6 Terra costs $0.043 per 1M input tokens and $0.259 per 1M output tokens on Qubax, versus $1.00 / $6.00 on OpenRouter (96% less on input). A typical 1,000 chat requests (2K tokens in, 500 out) come to about $0.22. Measured availability over the last 7 days: 79.0%. 121 independent compute providers currently serve it, so requests fail over automatically. It handled 7,772 requests on Qubax in the last 24 hours. Pay with USDC, USDT, BTC, ETH or 350+ other coins — no credit card required.
