What is GPT-4.1?  

GPT-4.1 is the latest iteration of the GPT-4o model, trained to excel at coding and instruction-following tasks. This model will improve the quality of agentic workflows and accelerate the productivity of developers across all scenarios. 

Key features of GPT-4.1 

GPT-4.1 brings several notable improvements:  

  • Enhanced coding and instruction following: The model is optimized for better handling of complex technical and coding problems. It generates cleaner, simpler front-end code, accurately identifies necessary changes in existing code, and consistently produces outputs that compile and run successfully.  

  • Long context model: GPT-4.1 supports one million token inputs, allowing it to process and understand extensive context in a single interaction. This capability is particularly beneficial for tasks requiring detailed and nuanced understanding as well as multi-step agents that increase context as they operate. 

  • Improved instruction following: The model excels at following detailed instructions, especially agents containing multiple requests. It is more intuitive and collaborative, making it easier to work with for various applications.
