Anthropic's Claude Opus 5.5 launches with cost cuts and speed boosts · 5 sources tracked

By PulseAugur Editorial · [5 sources] ·

Anthropic has released Claude Opus 5.5, a significant update that offers a 20% cost reduction per token and a claimed 30% increase in output speed. This new version also introduces a caching mechanism that drastically reduces costs for repeated queries, with reads costing 95% less than new input. While Opus 5.5 is optimized for coding tasks, some users find its predecessor, Opus 4.6, better suited for creative brainstorming due to its more collaborative interaction style. Separately, a project called LiveNerf is tracking Opus 5.5's performance to detect any silent degradation, reporting no significant changes detected thus far. AI

IMPACT Sets new SOTA on coding benchmarks; pressures Anthropic to respond.
