OpenAI is set to host a private, invite-only event in San Francisco on May 5 tied to GPT-5.5, according to an official event listing and a social media post by chief executive Sam Altman on Thursday.
The event, titled “GPT-5.5 on 5/5,” will take place from 5:55 p.m. to 8:55 p.m. PDT. Attendance requires prior registration and company approval; the exact venue will only be disclosed to confirmed participants.
The listing indicates the gathering will bring together a select group of developers and members of the OpenAI team for what is described as a “low-key meetup.”
Altman said in a post on X that the event's timing was chosen to align with the GPT-5.5 name. He added that responses to the invitation will help determine attendees, with internal systems assisting in the selection process.
OpenAI rolled out GPT 5.5 on April 24. The company described it as a “new class of intelligence for real work and powering agents.” It highlighted improvements in areas such as agentic coding, computer-based tasks, knowledge work, and early-stage scientific research.
The event branding and timing suggest the company may be preparing to showcase or preview an update to its GPT-5 model line, though it remains unclear whether any broader release will coincide with the gathering.
GPT-5.5 was rolled out to Plus, Pro, Business, and Enterprise users in ChatGPT and Codex, and GPT-5.5 Pro is rolling out to Pro, Business, and Enterprise users in ChatGPT.
OpenAI has continued to pair major product developments with a steady cadence of developer and policy-focused events, including recent OpenAI Forum sessions on AI in newsrooms, infrastructure, and real-world applications, alongside its flagship DevDay programming aimed at showcasing new tools and models.
The latest development follows a series of recent moves by the company, including the integration of its AI models and Codex agent into Amazon Bedrock, a generative AI service offered by Amazon Web Services, the cloud computing arm of Amazon.
The integration came shortly after the ChatGPT maker moved to loosen aspects of its long-standing relationship with Microsoft.
The timing also coincides with an ongoing legal dispute between OpenAI leadership and cofounder Elon Musk, with proceedings underway in a California court.
