# List of ChatGPT models for LLM Responses

**API:** Data API

**Endpoint:** `GET /v1/beta/dataforseo/ai_optimization/chat_gpt/llm_responses/models`

**Tags:** DataForSEO

The ChatGPT models available, each with `model_name`, `reasoning`, `web_search_supported` and `task_post_supported`. **Read it before calling** - an unlisted `model_name` is rejected with `status_code` 40501 inside an HTTP 200, and `task_post_supported` tells you whether the queued variant will work at all.

### Pricing reference

- Metering: Reported response cost.
- Reference request estimate: USD 0.012.
- Reference customer multiplier: 1.0. Do not apply it again to a settled customer amount.

Reference metadata only, not an account quote, a guaranteed price or a spending cap. Resource credits are not Felo credits. Final charges follow Felo billing records.

## Base URL
