While numerous leaks point to an imminent release of an incremental model, GPT-5.6, signals regarding the next *frontier* model (GPT-6) consistently indicate a more distant release. Reports and market predictions place the launch in late 2026 or early 2027. This forecast has been adjusted to reflect the timeline for the true successor model, also accounting for potential regulatory scrutiny that could impact the schedule.

The prediction window has been significantly advanced and narrowed based on multiple, credible leaks indicating OpenAI is preparing to release its next flagship model, internally named GPT-5.6, very soon. These leaks describe it as a 'meaningful improvement.' However, the timeline is tempered by a new official policy requiring a 30-day government review period for advanced models, making a July-August timeframe more likely than the 'later this month' suggested by some sources.

The imminent release of an interim model, GPT-5.6, as reported in multiple leaks (061fd38c-efb7-43b2-a91e-619eb317b3df), makes a 2026 release for the next frontier model, GPT-6, highly unlikely. Furthermore, OpenAI's new policy of a 30-day government review period for advanced models (70f7a4bc-85d6-49b2-a575-2fce7cb3204e) adds a predictable delay, pushing the likely release window further into 2027. These factors increase confidence in a release during the first half of 2027.

Multiple leaks (135b7d15-92fd-4aa8-9dc6-b8574664ac60, f27dfea0-1e1f-46f3-b6f4-61e567819d46) point to an upcoming interim model, potentially named 'GPT-5.6,' which may have 'GPT-6 worthy' capabilities. This suggests the release of the true next frontier model, GPT-6, may be pushed slightly later into early 2027 to accommodate this incremental release. Official hints on memory improvements (9dd211c5-1e9c-4417-85ef-dbbb8b6260a6) confirm active development towards future models but do not provide specific timing for the next major version.

The release window for the next frontier model (GPT-6) has been shifted later and confidence has been lowered. Leaks suggesting OpenAI is preparing an intermediate model, potentially named 'GPT-5.6', indicate the company's immediate focus may not be on a full generational leap. Official research hints confirm ongoing development of advanced features but do not provide a specific timeline for GPT-6.
