Mythos is a new tier, bigger than Opus, and more capable. It will be beyond the current state of the art by a wide margin, a dramatic jump in intelligence. Things have been accelerating under the surface since December. Capabilities are increasing faster, the time between model releases is getting shorter. I think OpenAI's recent decisions and refocus have been driven by the fact that it is increasingly obvious to some people working in the industry that we are beginning to take off. I think there have been multiple unannounced breakthroughs over the last few months, in more than one lab. I think there have been advances in capabilities, in alignment, and in architecture. The loop that started in December has begun to bear fruit. This model will be huge, very expensive to serve, and incredibly powerful. It has already finished training, and is in early rollout to some enterprise partners so they can prepare for what's about to arrive. Once we get benchmarks I think it will become clearer where we are; we are already inside the singularity.
