Rumor: GPT-6 Sol launches Tuesday, stronger and cheaper than Astra

A rumor circulating off X says GPT-6 Sol arrives Tuesday, that OpenAI treats an internal model called Bel as AGI, and that Anthropic moved Opus 5.5 up to Monday in response.

Rumors I’ve been hearing, not here on X. First, let’s start with OpenAI and I’ll go towards Anthropic. GPT-6 Sol is coming Tuesday. It’s both cheaper and more intelligent than 6 Astra, think of it like a 6.2 jump. The internal model “significantly more capable than Astra,” named Bel internally, helped with this release. Bel is considered “AGI” within OpenAI. They are very impressed with this model. OpenAI is growing very confident that their internal lead is so big that no other lab can catch up. Unbelievably confident. Anthropic is currently not in, let’s say, a “code red,” but is aware of OpenAI’s lead and doing everything in their power to catch up. Their new model Opus 5.5 is coming probably Monday rather than Tuesday due to OpenAI releasing on Tuesday.
