A post relaying unconfirmed rumors about upcoming frontier model releases.
- GPT-6-Sol: said to be another significant leap forward, with a price-performance ratio versus Astra that is "surprisingly good," most likely releasing on Tuesday.
- Opus 5.5: expected this week (today or tomorrow) in response to OpenAI's move, also a significant leap; OpenAI and Anthropic are currently neck and neck, with Opus answering GPT-6-Sol.
- Bel: what's new to the poster is that "Bel" is internally referred to as AGI at OpenAI. Given the graph still showing how quickly OpenAI's models keep improving, this isn't surprising.
The poster explicitly states they cannot confirm any of this and are only hearing the rumors.
