GPT

GPT is OpenAI's model family for text, code and various multimodal tasks through an API. Check the documentation for your chosen model to confirm its inputs, outputs, tool capabilities and request parameters.

For your own application, prepare several real requests and record whether the results meet your formatting and factual requirements. Treat API usage separately from a chat product subscription when planning integration and costs.

Specific GPT-6 models

• GPT-6 Astra — For demanding reasoning, coding and professional workflows.
• GPT-6.1 Sol — Balance capability and cost; see specifications, usage and pricing.
