Anthropic has launched Claude Opus 4.5, their latest AI model optimized for coding, enterprise applications, and complex tasks. This release, following Claude Sonnet and Haiku 4.5, marks Anthropic’s rapid innovation in the competitive AI field. Opus 4.5 reportedly outperforms rivals in agentic coding and excels in data analysis and problem-solving. It is available across Anthropic’s subscription tiers. The company also introduced updates to its ecosystem, including Chrome and Excel integrations, and expanded Claude Code. These enhancements focus on cross-platform accessibility and developer empowerment.

DeepSeek R1-0528 surpassed Claude Opus 4 in web programming, showcasing strong coding capabilities, especially with detailed prompts. Though performing well in web app development, it faltered with a Tetris game. R1 is also the top-performing open-source text model but has been recently surpassed by Kimi-Dev in open-source code.

DeepSeek unexpectedly updated its R1 model, rather than releasing R2. This trial upgrade, accessible via their website and apps, maintains the existing API. Early tests of the open-source R1 (0528) version show significant improvements, especially in programming, now rivaling international standards. The updated model excels in varied tasks from web design to text processing, sometimes outperforming other models like Claude 4.
