A leaked post says GPT-6 will miss an August launch because OpenAI wasn’t happy with its performance and is now targeting early September.
It also claims Anthropic is in the final testing stage for Fable 5.1, with a launch possibly as early as the second week of August. The source is explicitly informal and unverified.
