OPENAI Announced today that it publishes a new family of artificial intelligence models optimized to excel in coding, because it increases efforts to push the increasingly rigid competition of companies like Google and Anthropic. The models are available for developers via the OPENAI (API) application programming interface.
OPENAI publishes three model sizes: GPT 4.1, GPT 4.1 Mini and GPT 4.1 NANO. Kevin Weil, product manager at Openai, said on a live flow that the new models are better than the most used model of Openai, GPT-4O and better than his largest and powerful model, GPT-4.5, in some respects.
GPT-4.1 marked 55% on Swe-Bench, a widely used reference to assess the prowess of coding models. The score is of several percentage points above that of other Openai models. The new models are “excellent in coding, they are excellent in the complex education that follows, they are fantastic for the construction of agents,” said Weil.
The capacity of AI models to write and modify the code has improved considerably in recent months, allowing more automated software prototyping means and improving the capacities of so-called AI agents. In recent months, rivals like Anthropic and Google have both introduced models that are particularly good for writing code.
The arrival of GPT-4.1 has been largely rumor in recent weeks. Openai apparently tested the model on certain popular rankings under the pseudonym Alpha Quasar, according to sources. Some users of the “stealth” model reported Impressive coding capacities. “Quasar has solved all the open problems that I had with another code managed [sic] Via the LLM which were incomplete, “wrote a person on Reddit.
“The developers care a lot about coding and we have improved the ability of our model to write functional code,” said Michelle Pokrass, who works in post-training in Openai, during the Lunday Livestream. “We have worked to have it followed different formats and better explore references, perform unit tests and write compilation code.”
Over the past two years, Openai has aroused feverish interest in Chatgpt, a remarkable chatbot unveiled for the end of 2022, in an increasing company, selling access to more advanced chatbots and AI models. In a TED interview last week, Altman said that Optai had 500 million weekly active users and that the use “increased very quickly”.
OPENAI now offers a smorgasbord of different models of models with different capacities and different prices. The most important and powerful model of the company, called GPT-4.5, was launched in February, although Openai described the launch of “research preview” because the product is still experimental.
The company also offers models called O1 and O3 which are capable of performing a type of simulated reasoning, decomposing a problem in parts in order to solve it. These models also take more time to respond to requests and are more expensive for users.
Chatgpt’s success has inspired an army of imitators, and Rival AI players have accelerated their investments in research with the aim of catching OPENAI in recent years. A report on the state of the AI published by the University of Stanford this month has revealed that the models of Google and Deepseek now have capacities similar to the Openai models. He also showed a herd of other companies, notably anthropic, meta and the French company Mistral in the pursuit.
