OpenAI could release GPT-5.6 this month as a meaningful upgrade over its current flagship, while signaling a public listing may arrive within the next year.

Key Points:

• OpenAI is preparing GPT-5.6 for release this month, an upgrade over its April flagship, GPT-5.5.
• Chief scientist Jakub Pachocki described the model as a meaningful improvement in a message to staff.
• The company filed confidentially for an IPO and may go public within the next year.

OpenAI Readies GPT-5.6 Launch

OpenAI could push GPT-5.6 to users as soon as this month, according to a report that detailed the plans.

Chief scientist Jakub Pachocki told employees the model would mark a meaningful improvement over GPT-5.5, which the company shipped in April. The pace points to a tightening release cycle as rival labs trade flagship upgrades.

A release in the coming weeks would also line up with a broader overhaul of ChatGPT, the company's most-used product.

The company confidentially filed for an initial public offering with the SEC on Monday, and chief executive Sam Altman told staff he expects a debut within the next year, not this one. He added that several factors could shift the timing, and that filing now keeps the option to list sooner.

Altman Tempers OpenAI IPO Race

Altman struck a measured tone even as investors expect OpenAI and rival Anthropic to chase listings near $1 trillion. He cautioned that fast progress toward recursive self-improvement could give the firm reasons to stay private. That is the point where AI systems begin building and improving new AI on their own.

OpenAI counts more than 900 million weekly ChatGPT users and roughly $2 billion in monthly revenue, figures that frame talk of a debut valued near $1 trillion. Investors view the back-to-back AI filings as an early test of investor appetite for trillion-dollar listings.

Bankers cited in the report warned that huge AI offerings could pull investor money away from smaller listing candidates. Anthropic filed its own confidential paperwork on Jun. 1 and is widely expected to reach the market this year.

OpenAI, by contrast, sounds in no hurry, even while lining up a tender offer that prices staff shares at $687.69 each.

OpenAI's last private round in March valued the company near $852 billion, and it had once eyed a Wall Street debut as soon as September. The firm projected about $20 billion in annualized revenue heading into the filing, leaving GPT-5.6 as the next marker in an unusually fast year of model releases.
