# GPT-4o (Retired from ChatGPT, API-only)

OpenAI, released 2024-05-13

**Verdict: conditional.** GPT-4o (May 2024) has been superseded by the GPT-5.x family and delisted from OpenAI's flagship API pricing page. It remains available through the API but is no longer a current-generation model. Use only where migration to GPT-5.x is blocked; otherwise, GPT-5.5 or GPT-5.4 offer better performance at comparable cost. Last verified 2026-05-25.

## Pricing

- Input: $2.50 / 1M tokens
- Output: $10 / 1M tokens
- Context: 128K tokens

## Strengths

- Multimodal tasks (text, image, audio) with existing GPT-4o tooling
- Legacy API integrations and existing production workflows
- Function calling and tool use with mature SDK support
- New projects or greenfield applications — use GPT-5.x instead
- Tasks where GPT-5.5/5.4 outperforms at comparable cost
- ChatGPT consumer use — retired from product Feb 2026
- Projects requiring state-of-the-art reasoning or latest features
