Opus 5.5 details leak: pricing, context window and a win over Sol
A post says Opus 5.5 is in stealth testing, is stronger at 3D and frontend work, costs about 20% less than Opus 5.1, and beats GPT-6 Sol.
Opus 5.5 Coming This Tuesday - Opus 5.5 is in stealth testing under the codename claude-wafer-eap. It was previously to be Opus 5.2, but now they have changed their plan to Opus 5.5. - I think they changed it because Opus 5.5 has significant changes compared with Opus 5.1. - Its around the level of Astra and Fable 5.1, and in some areas can perform even better. - Its quite good at 3D and frontend work, with better attention to small details and more polished outputs. - Pricing: $4 input / $20 output per 1M tokens, $0.20 cache read / $5 cache write. Context window: 872K down from 936K. - This makes it around 20% cheaper than Opus 5.1. And this time, Opus 5.5 > GPT-6 Sol. Anthropic gonna be back.
