Anthropic releases Sonnet 5.5, which it calls a significantly cheaper, faster work partner
techcrunch ·
Anthropic has released Sonnet 5.5, the latest iteration of its mid-tier AI model, positioning it as a faster and more cost-effective work partner than its predecessor. The company highlights that this new version is 30 percent faster and exhibits a significantly slower rate of token burn compared to Sonnet 5. While less powerful than the Opus model in general hierarchy, Sonnet 5.5 demonstrates superior performance in agentic coding tasks by efficiently spawning multiple agents without exceeding cost limits. Additionally, the model possesses cyber capabilities comparable to Opus 5, making it the first Sonnet model to undergo the same rigorous cyber safeguards applied to higher-tier models. Anthropic also announced upcoming plans to release a new version of its smallest model, Haiku, within the coming weeks. This release continues the intense competition among major AI labs, following recent announcements from competitors like OpenAI and Meta. The update underscores Anthropic's focus on agility and efficiency for everyday tasks such as coding and document creation.
