GPT-4o mini

OpenAI has introduced GPT-4o mini, a smaller, more efficient, and cheaper model replacing GPT-3.5 Turbo. This follows similar moves by Anthropic (Claude 3 Haiku) and Google (Gemini 1.5 Flash).

Key features:

• Significantly smarter than GPT-3.5 Turbo, but not as capable as GPT-4o (see benchmark).
• 60% cheaper compared to GPT-3.5 Turbo.
• It's a vision model, meaning it can interpret images.
• Context window is as big as GPT-4o (128k).

Why a "weaker" model when there is a better one? Quite simply: Not every task needs the best model.

Recommendation: For simple tasks such as summarizing texts or improving formulations, 4o-mini is perfectly sufficient. When more knowledge and complex "thinking" is required, you resort to 4o.
