OpenAI is not planning to ship GPT-6 this year, but that doesn't necessarily mean the company will not release new models. OpenAI currently has several models in GPT-5. The default is GPT-5 Auto, which automatically switches between regular and reasoning models. OpenAI models Reasoning models can think longer to craft better answers. On the other hand, GPT-5-instant is based on a non-reasoning model and can answer questions faster. GPT-5's auto mode acts as a switch between the models, and it's triggered only when the system believes reasoning models can answer the query better. OpenAI has updated GPT-5 multiple times since its release, but what about GPT-6? Is it coming sooner rather than later? OpenAI denies GPT-6 rumours While speaking to CNBC, Evercore ISI's Mark Mahaney, who is an analyst, claimed that GPT-6 is coming by the end of the year with step improvements. This claim immediately went viral on X, but OpenAI officials have denied the reports. Roon (the pseudonymous X account @tszzl), who is recognized as an OpenAI employee, denied the reports. This means GPT-6 is not happening in 2025, but we might see other model updates, such as GPT-5.5, perhaps?
