Anthropic's Claude Opus 4.5 is Live in Cline

Claude Opus 4.5, now available through the Cline provider, showcases significant improvements in performance and efficiency over previous models, achieving high scores on SWE-bench and Terminal-bench 2.0. This model uses up to 65% fewer tokens for comparable tasks and is priced at $5 per million input tokens and $15 per million output tokens with a 200K context window. While Sonnet 4.5 remains suitable for straightforward tasks, Opus 4.5 is recommended for complex, multi-step problems that require advanced reasoning and less guidance. Internal testing by Anthropic indicates that Opus 4.5 handles intricate multi-system bugs effectively, surpassing Sonnet 4.5 in SWE-bench scores while utilizing significantly fewer tokens. The model's efficiency in long Cline sessions results in more work accomplished per dollar spent, and users are encouraged to share their experiences with complex tasks on platforms like Reddit or Discord.
