References to “gpt-5-reasoning-alpha-2025-07-13” have already been spotted on X, with code displaying “reasoning_effort: excessive” within the mannequin configuration. These sightings recommend the mannequin has entered remaining testing phases, with testers getting their fingers on the code and safety specialists doing purple teaming on the mannequin to check vulnerabilities.
Unifying OpenAI’s mannequin lineup
The brand new mannequin represents OpenAI’s try to simplify its more and more advanced product lineup. As Altman explained in February, GPT-5 could combine options from each the corporate’s typical GPT fashions and its reasoning-focused o-series fashions right into a single system.

Based on The Information, GPT-5 is anticipated to be higher at coding and extra highly effective total, combining attributes of each conventional fashions and SR fashions reminiscent of o3.
Earlier than GPT-5 arrives, OpenAI nonetheless plans to launch its first open-weights mannequin since GPT-2 in 2019, which suggests others with the correct {hardware} will be capable to obtain and run the AI mannequin on their very own machines. The Verge describes this mannequin as “much like o3 mini” with reasoning capabilities. Nevertheless, Altman announced on July 11 that the open mannequin wants further security testing, saying, “We’re not but certain how lengthy it should take us.”
