What is GPT-4.1 in the API?
A new series of GPT models featuring major improvements on coding, instruction following, and long context—plus our first-ever nano model.
Problem
Users previously relied on older GPT models (e.g., GPT-4) for AI-driven tasks, facing challenges with coding accuracy, instruction adherence, and handling long contexts, leading to inefficiencies in development and application performance.
Solution
An API offering GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano models, enabling developers to integrate enhanced AI capabilities for coding, instruction-following, and long-context tasks (e.g., generating code snippets or processing lengthy documents).
Customers
Developers, data scientists, and AI engineers building applications requiring advanced NLP and coding support.
Unique Features
First nano model for lightweight efficiency, major improvements in coding and instruction-following, and extended context handling up to 128k tokens.
