Models
Choosing a model
If you're not sure where to start, use gpt-5.4, our flagship model for complex reasoning and coding. If you're optimizing for latency and cost, choose a smaller variant like gpt-5-mini.
All latest OpenAI models support text and image input, text output, multilingual capabilities, and vision. Models are available via the Responses API and our Client SDKs.
Frontier models
Start with gpt-5.4 for complex reasoning and coding, or choose gpt-5-mini for lower latency and cost.
