OpenAI Releases GPT-4.1 Series

Home AI News OpenAI Releases GPT-4.1 Series

On April 15, OpenAI announced the launch of the GPT-4.1 model family, including GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano. These models are currently available exclusively via API, targeting developers rather than general users.

According to OpenAI, the GPT-4.1 series significantly outperforms its predecessors, GPT-4o and GPT-4o mini, in several key areas—such as code generation, instruction following, and long-context comprehension. One of the standout features is the expanded context window, which can now handle up to 1 million tokens, enabling the models to process much longer and more complex inputs. Additionally, the models’ knowledge has been updated through June 2024, making them more accurate and relevant for current real-world applications.

Performance improvements are especially notable in programming tasks. Compared to GPT-4o, GPT-4.1 achieves a 40% increase in code generation speed while reducing the cost of user input queries by 80%. These upgrades are expected to benefit developers building AI-powered applications, from writing assistants to automation tools.

At this stage, GPT-4.1 models are not yet integrated into the public ChatGPT interface, meaning regular users won’t be able to try them out directly. However, OpenAI may roll out broader access in the future as part of its product roadmap.

The release of the mini and nano versions also indicates OpenAI’s ongoing effort to offer more efficient, lightweight models—suitable for a wider range of deployment environments, including mobile and edge devices.
