Model Information
Display Name: GPT-5.6 Terra
API Model ID: openai/gpt-5.6-terra
Category: Image To Text
Description: GPT-5.6 Terra is the middle tier of OpenAI's GPT-5.6 line: the same 1.05M-token context window and reasoning controls as Sol at a fraction of the price, aimed at everyday production workloads. **Key Features:** - 1,050,000-token context window - Up to 128K output tokens - Multimodal input: text, image and file - Function/tool calling and structured outputs (JSON schema) - Reasoning with adjustable effort, including fully disabled - Prompt caching for cheaper repeated context **Best For:** - General production reasoning at a moderate price - Long-document and long-conversation workloads - Tool-driven assistants and extraction pipelines **Note:** prompts above 272K tokens are billed by OpenAI at double the base rate. Our price is flat and already accounts for it.
Context Window: 1,050,000 tokens
Max Output: 128,000 tokens
