Article Summary
Anthropic has announced the release of Claude Sonnet 4.5, the latest iteration in its ‘frontier AI’ model family, aiming to directly compete with OpenAI’s GPT-5. The model’s key selling point is its performance on coding benchmarks, achieving industry-leading results, including on the SWE-Bench Verified tests. However, Anthropic researchers emphasize that benchmarks alone don't fully capture the model’s potential, citing instances of Sonnet 4.5 autonomously building applications for up to 30 hours, handling tasks like database creation, domain registration, and SOC 2 audits. Beyond simple coding, the model demonstrates an ability to manage complex, long-horizon tasks, supported by the newly launched Claude Agent SDK. Anthropic is also releasing ‘Imagine with Claude’ as a research preview, allowing users to generate software in real-time via Max subscribers. This represents a significant push into building an ecosystem around the Claude model, leveraging its alignment and reduced tendency for deception. The launch coincides with the introduction of the Claude Agent SDK, further extending the model's utility for developers.Key Points
- Claude Sonnet 4.5 achieves state-of-the-art performance on coding benchmarks, rivaling OpenAI’s GPT-5.
- The model can autonomously handle complex tasks like building production-ready applications, managing databases, and conducting security audits.
- Anthropic is expanding its ecosystem with the Claude Agent SDK and research previews like ‘Imagine with Claude’.
