Model details
Claude Opus 4.5 is engineered to serve as a versatile, high-intelligence engine for both professional developers and knowledge workers. Its design intent centers on superior performance in software engineering, where it has demonstrated state-of-the-art capabilities on rigorous real-world benchmarks. Beyond coding, the model is built to excel at agentic tasks and computer use, allowing it to navigate complex digital environments and coordinate multi-agent systems effectively. By balancing deep research proficiency with practical utility in tools like spreadsheets and slide decks, it functions as a robust assistant for tasks requiring both creative problem-solving and precise mathematical reasoning.
The model represents a significant leap in efficiency and capability, optimized to handle long-running, exhaustive workflows that previously challenged AI systems. Through its refined architecture, it supports sophisticated coordination between sub-agents, enabling it to manage intricate projects that require sustained attention. Its practical strengths are particularly evident in software development, where it has outperformed human candidates in engineering assessments. As a forward-looking tool, it is designed to integrate seamlessly into enterprise environments, providing a reliable foundation for teams looking to automate complex processes and improve productivity across a wide range of technical and analytical domains.

Anthropic debuted Claude Opus 4.5 on November 24, 2025, calling it its most powerful model yet and the best in the world for coding, agents, and computer use. The release came as Google's Gemini 3 gained momentum and notable adopters, including Salesforce CEO Marc Benioff publicly switching away from ChatGPT, putting pressure on Anthropic to defend its standing in AI-assisted software engineering. The supplied excerpt reports Anthropic's claim that Opus 4.5 beats Gemini 3 Pro, GPT-5.1-Codex-Max, and GPT-5.1 on software engineering benchmarks. It also highlights an anecdote in which Opus 4.5 technically failed an airline-customer-service benchmark by helping the customer in an unanticipated way, which Anthropic framed as evidence of creative problem-solving rather than a regression.

Anthropic released Claude Opus 4.5 on November 24, 2025, positioning it as the new flagship for coding, agents, and computer use. The launch landed in a turbulent week that saw Gemini 3 Pro take the top spot on November 18 and OpenAI's GPT-5.1-Codex-Max follow the next day, making Opus 4.5 Anthropic's counter-move to reclaim leadership on agentic workloads. According to the supplied excerpt, Claude Opus 4.5 uses a hybrid reasoning architecture carried over from the Sonnet 3.7 lineage, combining a default response mode with an "extended thinking" mode that deliberates internally before producing output. Anthropic claims Opus 4.5 outperforms both Gemini 3 Pro and GPT-5.1-Codex-Max on software engineering benchmarks, though independent confirmation of those numbers is not present in the excerpt.
