OpenAI Introduces GPT-4.1, a Successor to the GPT-4o Multimodal AI Model
GPT-4.1 is a successor to the GPT-4o multimodal AI model launched by OpenAI last year. During a livestream on Monday, OpenAI announced that GPT-4.1 has an even larger context window and is better than GPT-4o in “just about every dimension,” with significant improvements to coding and instruction following.
Main Features of GPT-4.1
GPT-4.1 is now available to developers, along with two smaller model versions: GPT-4.1 Mini and GPT-4.1 Nano. GPT-4.1 Mini is more affordable for developers to experiment with, while GPT-4.1 Nano is the smallest, fastest, and cheapest model yet.
Improved Context Window
All three models can process up to one million tokens of context – the text, images, or videos included in a prompt. This is a significant improvement over GPT-4o’s 128,000-token limit. OpenAI claims that GPT-4.1 is trained to reliably attend to information across the full 1 million context length and is more reliable at noticing relevant text and ignoring distractors across long and short context lengths.
Phase-out of GPT-4 and GPT-4.5
OpenAI plans to phase out its two-year-old GPT-4 model from ChatGPT on April 30th, as recent upgrades to GPT-4o make it a “natural successor” to replace it. The company also plans to deprecate the GPT-4.5 preview in the API on July 14th, as GPT-4.1 offers improved or similar performance on many key capabilities at much lower cost and latency.
Reasoning Models
OpenAI is also set to debut the full version of its o3 reasoning model and an o4 mini reasoning model any day now. References to these models have already been spotted in the latest ChatGPT web release by AI engineer Tibor Blaho.
Conclusion
GPT-4.1 is a significant improvement over its predecessor, with a larger context window and better performance on coding and instruction following. The launch comes as OpenAI plans to phase out older models and focus on newer, more powerful technology.
