GPT-4 by OpenAI

GPT-4o mini scores 82% on MMLU and currently outperforms GPT-4 on chat preferences. It is priced at 15¢/million input tokens and 60¢/million output tokens, an order of magnitude more affordable than previous frontier models and 60+% cheaper than GPT-3.5 Turbo.

GPT-4o (“o” for “omni”) is a step towards much more natural human-computer interaction—it accepts as input any combination of text, audio, and image and generates any combination of text, audio, and image outputs.
