UnverifiedThe improvement in agentic capabilities is accompanied by exponential growth in token consumption, and Sonnet 5's token consumption in maximum-effort mode is comparable to OPUS but with worse results.69% similarUnverifiedOutput tokens are typically more expensive than input tokens because outputs require autoregressive token-by-token generation, which has higher computational intensity and lower GPU utilization.65% similarVerifiedOpus 5.5 reaches the level of Fable 5.1 on most tasks, but with approximately 40% lower operating costs and faster speed.65% similarUnverifiedThe new Claude Sonnet released by Anthropic is more than 30% faster than the previous generation Sonnet, with costs reduced by up to 30% in most work scenarios at the same price.64% similarUnverifiedSlack's principal engineer reported that, without modifying existing prompts, Sonnet 5.5 performs better and faster, with output tokens reduced by approximately 14%.63% similar
