Soo, from what I see in comparison to GPT-5.5 it's: - Generally marginally more intelligent - Not as strong in coding - Best agentic model out there by a margin In terms of efficiency: - Slightly cheaper than 4.7, but still the most expensive of the frontier models by far - Quite a token guzzler compared to GPT-5.5 - Double as fast compared to GPT-5.5 in end-to-end response time See the results here: https://artificialanalysis.ai/models/claude-opus-4-8 submitted by /u/elemental-mind [link] [comments]
