Model Information

Display Name: GPT-5 Mini

API Model ID: openai/gpt-5-mini

Category: Image To Text

Description: GPT-5 Mini is a compact version of GPT-5 for lighter-weight reasoning tasks. It keeps GPT-5's instruction following and safety tuning with lower latency and cost, over a 400K-token context window. **Key Features:** - 400,000-token context window - Up to 128K output tokens - Multimodal input: text and image - Function/tool calling and structured outputs (JSON schema) - Reasoning with adjustable effort - Prompt caching for cheaper repeated context **Best For:** - High-volume chat and assistant workloads - Everyday reasoning at low cost - Instruction-following and structured extraction - Long-document question answering

Context Window: 400,000 tokens

Max Output: 128,000 tokens
