Anthropic Accelerates AI Race with Claude Opus 4.5 Launch Following $350B Valuation

Anthropic has unveiled Claude Opus 4.5 just weeks after releasing its Sonnet and Haiku models, demonstrating breakneck development pace as competitors scramble to match its progress. The AI firm, founded by OpenAI alumni, achieved a staggering $350 billion valuation after fresh investments from Microsoft and Nvidia.

The new model specifically targets knowledge workers and developers, boasting superior performance in spreadsheet analysis, presentation creation, and deep research tasks. Product chief Scott WHITE emphasized the company's rapid iteration cycle, stating the release cadence generates valuable market feedback loops.

Claude Opus 4.5 establishes new benchmarks in agentic coding, outperforming both Google's recently announced Gemini 3 Pro and OpenAI's GPT-5.1. The accelerated rollout schedule—following August's 4.1 release—signals Anthropic's determination to maintain technological leadership in the intensifying AI arms race.
