Anthropic releases Sonnet 5.5, a faster and more cost-effective AI model
Anthropic has launched the latest version of its mid-tier AI model, Sonnet 5.5, emphasizing improved speed and reduced costs compared to its predecessor, Sonnet 5. The company highlights that Sonnet 5.5 is up to 30% faster with a slower token burn rate, making it more efficient for everyday tasks like coding and document creation. Positioned below the Opus model in Anthropic’s hierarchy but noted for agility, Sonnet 5.5 outperforms Opus on agentic coding due to its ability to handle multiple agents within cost limits. Anthropic also claims that Sonnet 5.5 has comparable cybersecurity capabilities to Opus 5 and will be subject to the same cyber safeguards as higher-tier models like Fable and Opus. The release comes amid a wave of new AI model introductions from major labs, including OpenAI and Meta. Anthropic plans to roll out an updated version of its smallest Haiku model in the near future. The launch underscores ongoing competition among AI developers for efficiency, performance, and cost-effectiveness.
