Regardless of what its identify suggests, GPT-4.1 is meant to be higher and extra environment friendly.
OpenAI says GPT-4.1 is offered solely to developer’s utilizing OpenAI’s API, and is available in three sizes, GPT-4.1, GPT-4.1 mini and GPT-4.1 nano. That implies that when you will not discover it as in possibility within the public-facing ChatGPT interface, however you possibly can sometime work together with an agent that leverages the mannequin’s enhancements. GPT-4.1 is meant to be higher at coding and “lengthy context understanding,” in response to OpenAI, with assist for “as much as a million tokens of context” and data of the world as much as June 2024.
Vital to the choice to section out the GPT-4.5 Preview, GPT-4.1 can be cheaper to run. OpenAI says the mannequin is “26 % cheaper than GPT-4o for median queries.” The corporate imagines builders utilizing GPT-4.1 to construct brokers that may work in software program engineering environments, one of many extra in style makes use of for generative AI. Though GPT-4.5 will probably be ultimately faraway from OpenAI’s API, the mannequin preview will nonetheless be accessible in ChatGPT when you wan’t to play with it.
OpenAI says the GPT-4.1 household is offered to make use of immediately by way of the corporate’s API. GPT-4.5 will probably be fully-phased out in three months on July 14, 2025.
