GPT-5 arrived in August 2025 with a question attached
OpenAI gave its new model to every ChatGPT user at once. Early reviewers found a smaller leap than before, and investors asked what the spending would return.

This is a look back at an event from . We wrote it on November 11, 2026, from the sources listed at the end.
What to know
- OpenAI released GPT-5 on August 7, 2025, to all of ChatGPT's roughly 700 million users.
- The model decides for itself when a question needs extra reasoning time, a feature the general public had not had before.
- Two early reviewers told Reuters the improvement over GPT-4 was smaller than earlier generational jumps.
OpenAI released GPT-5 on August 7, 2025, and made it available to everyone using ChatGPT, about 700 million people at the time according to Reuters. GPT-4 had gone to paying subscribers first.
What was new
OpenAI said the model was strongest at writing software, and better at writing, health questions and finance. The structural change was routing. GPT-5 judges each request and gives harder ones more processing time to reason before answering. Free users had not had access to that kind of extended reasoning before.
The reception
Two people who tested the model early told Reuters that the step up from GPT-4 looked smaller than OpenAI's previous upgrades, though they were impressed by its coding and its handling of science and math problems.
That mattered because of the money involved. Reuters noted that Alphabet, Meta, Amazon and Microsoft expected to spend close to $400 billion that fiscal year, most of it on AI data centers, and that OpenAI was in early talks about an employee share sale valuing it at $500 billion. Spending on that scale assumes each generation of models is good enough to win paying business customers.
How it reads now
The question raised that week did not go away. It is the same one behind the AI selloff of November 2026, when investors marked down the companies building data centers. A model release in August 2025 was the first time many people outside the industry asked it out loud: are the gains keeping up with the bills?
For the limit that shapes how these models handle long conversations, see what a context window is.
