On November 24, 2025, Anthropic launched its advanced language model, Claude Opus 4.5, aimed at dominating enterprise integration, coding, and agent control. Unlike previous iterations, this model features an “Effort Parameter” that allows developers to customize computing effort for optimal response quality, slashing costs significantly—from $15 to $5 for input tokens and from $75 to $25 for output tokens. Targeting competitors like OpenAI’s GPT-5.1 and Google’s Gemini 3 Pro, Opus 4.5 excels in real-world coding benchmarks, establishing itself as a robust, specialized tool for automation and software development. With a generous 200,000 token context window, the model facilitates longer conversations and workflows, though it raises security concerns like prompt injections. Instead of competing for flashy features, Claude Opus 4.5 focuses on efficiency and reliability for knowledge workers, positioning itself as a formidable choice for enterprises seeking stable, scalable AI solutions.
