<h1>OpenAI Launches GPT-4.1 AI Models with Focus on Coding</h1>
OpenAI has introduced its latest family of AI models, GPT-4.1, designed to enhance coding and instruction following, and is now available through its API. The GPT-4.1 series includes three variants: GPT-4.1, GPT-4.1 Mini, and GPT-4.1 Nano, all excelling in complex software engineering tasks with an improved 1-million-token context window for handling long-context understanding.
This launch comes alongside the planned yet delayed release of GPT-5, as OpenAI addresses some integration challenges. In addition to coding, GPT-4.1’s reach extends to reasoning tasks, with new o3 and o4 reasoning models set for release in both full and mini versions. The smaller GPT-4.1 Mini and Nano versions offer more affordable and faster alternatives for developers.
OpenAI has also made GPT-4.1 available through GitHub Copilot and GitHub Models, promoting its application in coding, instruction following, and AI application enhancement. It features a refreshed knowledge cutoff of June 2024 and can be enabled by administrators through a new policy for all Copilot plans. Moreover, GitHub Codespaces has introduced an Agentic AI feature to facilitate streamlined coding from GitHub issues.
In light of the GPT-4.1 launch, OpenAI plans to phase out GPT-4.5, its largest AI model to date, by July 14 from its API, encouraging developers to shift to GPT-4.1 for similar or improved performance at a lower cost. Although GPT-4.5 will remain available in ChatGPT for paying customers, it has been noted for high running costs and failing to meet certain industry benchmarks.
The release of GPT-4.1 represents a significant milestone for OpenAI, as it continues to refine the balance between cost efficiency and performance, especially in complex coding and instruction-following applications.
