OpenAI says GPT-6 is now available and opens developer hackathons in San Francisco and New York

OpenAI announced that GPT-6 is available and, at the same time, launched a series of hackathons aimed at developers, technical founders and product builders. The first two events will take place in San Francisco on September 8 and in New York on September 10, according to a post from the company's developer account on X.

The hackathons are structured as single-day build sessions. Participants are asked to arrive with an idea or an existing prototype, work alongside other local developers and receive hands-on support from OpenAI staff on site. The stated goal is to reach a live demo of the product or feature by the end of the day.

The events are intended specifically for developers, technical founders and product people, not the general public. Registration for the San Francisco session is open through a link included in the announcement; no separate link for New York was published in the original post.

The announcement includes no technical details about GPT-6 itself. No benchmarks, context-window size, API pricing, rate limits or general-availability date beyond the hackathons were disclosed. It also does not say whether the model is already accessible through the public API or only to event participants.
