OpenAI adds GPT-4.1 models to ChatGPT

OpenAI is introducing two new AI models, GPT-4.1 and GPT-4.1 mini, to ChatGPT. The GPT-4.1 model will be available to paying subscribers on the ChatGPT Plus, Pro, and Team plans. The GPT-4.1 mini model, meanwhile, will be made available free of charge to all ChatGPT service users.

With the introduction of the new models, OpenAI is phasing out the existing GPT-4.o mini model in ChatGPT, it said a post on X.

The new models are coming at a time when interest in AI tools to support programming is growing. The GPT-4.1 model offers more help to developers creating applications: Compared to the earlier GPT-4o mini model, the GPT-4.1 model offers higher performance in terms of coding and command execution.

The GPT-4.1 and GPT-4.1 mini models debuted in April of this year and were heavily criticized at the time for the lack of a report discussing their security level. Responding to this charge, OpenAI argued that the models do not support new modes of interaction, so their security requirements are different from those of the most advanced models and thus the criticism is unjustified.

The vendor also said it will publish the results of internal security assessments of both models more frequently. The data will be available on the company’s newly launched Safety Evaluations Hub, which shows safety evaluation results for OpenAI’s models in four categories: harmful content, jailbreaks, hallucinations, and adherence to instructions hierarchy.
