Pressure on Anthropic to make a big leap with next iteration of all of their models. Fable is too expensive for most tasks, and Opus 5 is a bust. GPT models are better and faster than their Anthropic equivalents. Open weights models with Opus level performance at 1/100th ramps up the pressure.

like GLM 5.3 Flash is currently >200x cheaper than Opus 4.8, until 9 September, which it matches and exceeds in some areas.
