OpenAI has made a major advancement in artificial intelligence with the launch of its GPT-4.1 model family. Available since April 2025 for developers and since May 15 for ChatGPT users, this new generation brings substantial improvements in performance and efficiency.
The New Model Family
The GPT-4.1 series includes three variants designed for different needs:
- GPT-4.1: The main model with enhanced capabilities
- GPT-4.1 mini: A lighter version that matches or surpasses GPT-4o at 83% lower cost
- GPT-4.1 nano: The most compact and fastest version, ideal for simple tasks
“This model diversification responds to a growing trend in the market: the need for AI solutions tailored to different use cases and budgets,” says Guillermo Reynoso, director of BIG Hacks, a consultancy specializing in AI solutions for businesses.
Notable Improvements
Some of the most significant advancements include:
- Improved coding capabilities, reducing unnecessary edits from 9% to 2%
- Higher accuracy with complex instructions
- Maintenance of a 1 million token context window
- Integration as the default model in GitHub Copilot since May 8
The Race for Leadership in Generative AI
The arrival of GPT-4.1 intensifies competition in the generative AI space, where Google Gemini, Anthropic Claude, and Meta Llama are also striving for dominance. For businesses working with an SEO agency, these tools offer new opportunities to optimize content and digital strategies.
OpenAI’s initial focus on the API rather than the user interface reflects its priority to meet developers’ needs first, solidifying its position as a platform for building AI-powered applications.
Key Changes
OpenAI has also announced:
- The discontinuation of GPT-4.5 Preview as of July 14, 2025
- Price reductions: GPT-4.1 is approximately 26% cheaper than GPT-4o
- Removal of additional charges for extended context usage
These changes, along with the recent $3 billion acquisition of Windsurf, indicate a strong commitment to AI-assisted coding tools.
Looking Ahead
Despite criticism over the lack of safety documentation, OpenAI has established a Safety Evaluations Center and committed to publishing results more regularly.
How will businesses leverage these new capabilities to stay competitive in an environment where AI is constantly rewriting the rules?
