GPT-4.1 Mini vs GPT-4o Mini: What's the Difference?

GPT-4.1 mini vs GPT-4o mini is a key question for businesses. Here is a comparison:

GPT-4.1 mini is faster and handles longer contexts, but some users note that it is less “warm” than GPT-4o mini.

Price Comparison and Access

GPT-4.1 mini costs $0.40 per million tokens input et $1.60 exit, more expensive than GPT-4o mini, but 83% cheaper than 2023 models.

For a European startup, this means significant savings on high-volume tasks, such as chatbots.

Strengths and Limitations in Coding

Forces :

• Excellent in coding (SWE-bench 21.4%).
• Ideal for simple tasks like text classification.

limitations :

• Less efficient for complex reasoning compared to GPT-4.1 full.

Example: Perfect for automating scripts, but less so for advanced theoretical analyses.

Why GPT-4.1 Mini Domine in 2025?

Facing GPT-5 mini backlash, criticized for its latency (7-10s), GPT-4.1 mini remains a reliable choice for fast and economical tasks.

GPT-4.1 Mini vs GPT-5 Mini and Other Models

How does GPT-4.1 mini compare to GPT-5 mini and competitors like Claude Haiku or Gemini Flash?
