Anthropic releases Sonnet 5.5, which it calls a significantly cheaper, faster work partner
Anthropic says Sonnet 5.5 is 30% faster than Sonnet 5 and burns tokens more slowly.
The company is pitching the mid-tier model as a cheaper everyday assistant for coding and office-document work. TechCrunch notes Anthropic’s benchmarks show it outperforming Opus 5.5 on agentic coding, likely because it can run multiple agents without blowing past cost limits. Anthropic also says Sonnet 5.5 has cyber capabilities comparable to Opus 5, so it will get the same cyber safeguards used for Fable and Opus. TechCrunch AI's note
