GPT-4
OpenAI's most capable language model, released March 2023, with improved reasoning, coding, and multimodal abilities.
Think of it like
The leap: GPT-3 was impressive, but GPT-4 convinced everyone LLMs could think.
Example
GPT-4 passed the bar exam (top 10%), wrote code for unfamiliar libraries, and analyzed images (multimodal).
How it actually works
GPT-4 uses chain-of-thought reasoning at inference time; can solve more complex problems than GPT-3.5. Multimodal (image + text input) added later. Launched as gated release for safety. GPT-4 Turbo (2023) added 128k context and lower costs.
For product teams
Premium pricing justified by capability; used for high-stakes applications (legal, coding, research).
For engineers
Frontier model for reasoning and code; expensive but often worth it for complex tasks.
