Anthropic's Claude Sonnet 5.5 Is Out, Beats Opus 5.5 at Coding for Half the Price

Claude Sonnet 5.5 costs approximately 50% less per token than Opus 5.5, according to Anthropic's pricing structure. However, independent testing indicates Sonnet 5.5 consumes more total tokens per task, potentially offsetting per-token savings in real-world deployment scenarios.

Terminal-Bench 4.0 is an independent coding performance benchmark used to evaluate large language models. Sonnet 5.5 outperformed Opus 5.5 on this metric, making it relevant for developers and enterprises evaluating model selection for coding tasks and API integration decisions.

Lower inference costs create pricing pressure on decentralized compute providers like Render and Akash. Increased competition may compress margins on GPU infrastructure services, but broader AI adoption could increase total compute demand across blockchain networks and centralized providers.

Token burn refers to total tokens consumed by a model to complete a task. Even with lower per-token pricing, models that consume more tokens increase effective costs. Independent testing suggests Sonnet 5.5's higher token consumption may partially offset its 50% per-token price reduction.

Developers should benchmark Sonnet 5.5 on their specific workloads before deployment. While coding performance is strong, total token consumption varies by task type. Cost savings depend on actual production usage patterns rather than headline per-token pricing alone.
