OpenAI’s flagship GPT-4.1 model is now in ChatGPT

The Verge - May 15th, 2025

OpenAI has unveiled the latest versions of its GPT AI models, GPT-4.1 and GPT-4.1 mini, which are now available to all paid ChatGPT account tiers. This rollout excludes free users, but OpenAI plans to extend access to Enterprise and Edu users in the coming weeks. The new models are optimized for coding tasks and instruction following, promising better performance than their predecessors, GPT-4o and GPT-4o mini. Notably, both models support a one million context token window, a significant increase from the previous 128,000-token limit, and offer speed improvements for everyday coding tasks.

The introduction of GPT-4.1 reflects OpenAI's ongoing efforts to enhance the capabilities of its AI models. These updates are positioned to benefit developers and users requiring advanced coding functionalities. While GPT-4.1 and the more efficient GPT-4.1 mini are part of this rollout, the GPT-4.1 Nano model, noted for its speed and cost-effectiveness, is not included and its availability remains uncertain. This development underscores OpenAI's commitment to maintaining a competitive edge in AI technology, as it continues to cater to diverse user needs within the ChatGPT platform.

Fair Story

Consider it well-founded

The article provides a clear and timely update on OpenAI's rollout of the GPT-4.1 and GPT-4.1 mini models, making it a valuable read for those interested in AI advancements. It accurately reports on the availability and capabilities of the new models, although some claims, like the context token window, require further verification. The piece could benefit from more balanced coverage by including external perspectives or critiques, which would enhance its depth and credibility. While the technical nature of the content may limit its appeal to a broader audience, it remains an informative piece for tech enthusiasts and professionals. Overall, the article effectively communicates the key updates from OpenAI, though it could improve in areas such as source diversity and transparency.

Accuracy

The story is largely accurate in its depiction of OpenAI's rollout of GPT-4.1 and GPT-4.1 mini models to ChatGPT users. It accurately states that GPT-4.1 is available across all paid tiers and that free users are excluded from this rollout, which aligns with OpenAI's announcements. However, the claim about the context token window supporting a one million token limit requires further verification, as the sources do not explicitly confirm this detail. Additionally, while the story mentions speed improvements, it lacks specific comparisons to previous models, which could enhance the factual precision.

Balance

The article primarily focuses on the technical upgrades and availability of OpenAI's new models, presenting a positive view of the advancements. However, it does not include perspectives from users or experts outside of OpenAI, which could provide a more balanced view of the impact and potential drawbacks of these updates. The story could benefit from including critiques or concerns about the rollout, such as potential issues with accessibility for free users.

Clarity

The language and structure of the article are clear and straightforward, making it easy to follow the main points about the new GPT models. The article logically sequences the information, starting with the announcement and moving into specific details about the models. However, the technical jargon, such as 'context token window,' might be challenging for readers unfamiliar with AI terminology, slightly affecting overall comprehension.

Source quality

The article appears to rely heavily on OpenAI's announcements and information, which are credible sources for details about their own products. However, it lacks external sources or independent verification, which could enhance the credibility and reliability of the reporting. Including expert opinions or user feedback would provide a more comprehensive view and mitigate potential biases from relying solely on OpenAI's perspective.

Transparency

The article clearly states the rollout details and model capabilities, but it lacks transparency in terms of methodology or how the information was gathered. The absence of explicit references to sources or data collection methods limits the reader's ability to assess the basis for the claims made. Additionally, potential conflicts of interest, such as financial ties to OpenAI, are not disclosed, which could impact the perceived impartiality of the report.
