OpenAI also release the GPT4-O API this time. Here are what's changed in gpt4o comparing with gpt4-Turbo.

High intelligenceGPT-4 Turbo-level performance on text, reasoning, and coding intelligence, setting new high watermarks on multilingual, audio, and vision capabilities.
2x fasterGPT-4o is 2x faster at generating tokens than GPT-4 Turbo.
50% cheaper pricingGPT-4o is 50% cheaper than GPT-4 Turbo, costing $5 per million input tokens and $15 per million output tokens.
5x higher rate limitsGPT-4o has 5x the rate limits of GPT-4 Turbo, up to 10 million tokens per minute. Rate limits will ramp up to this level for high usage developers in the coming weeks.
Improved visionGPT-4o has enhanced vision capabilities across the majority of tasks.
Improved non-English language capabilitiesGPT-4o uses a new tokenizer for more efficient non-English text tokenization and has improved capabilities in non-English languages.
Context window and knowledge cut-offGPT-4o has a 128K context window and a knowledge cut-off date of October 2023.
Video understanding in APIGPT-4o supports understanding video (without audio) via vision capabilities by converting videos to frames (2-4 frames per second) for input.
Audio support in APIGPT-4o in the API does not yet support audio but aims to bring this modality to trusted testers in the coming weeks.
Image generation support in APIGPT-4o in the API does not support generating images. DALL-E 3 API is recommended for this purpose.
Recommendation for usersUsers of GPT-4 or GPT-4 Turbo are recommended to evaluate switching to GPT-4o. API documentation and Playground support for vision and comparing output across models are available.

This table summarizes the key features and improvements of GPT-4o, highlighting its enhanced performance, cost-effectiveness, and capabilities in vision and multilingual support.


The launch of ChatGPT-4O marks a monumental step forward in the evolution of conversational AI.
