Claude Opus 4.6 Sets 14.5-Hour Agentic Task Horizon; Claude Gains Wall Street Traction as Alternative to GPT

Anthropic's Claude Opus 4.6, released in February 2026, established a record 50%-time horizon of 14 hours and 30 minutes on METR benchmarks and scored higher than any human candidate on Anthropic's internal engineering benchmark. Agent team functionality is experimentally available in Claude Code for Max, Team, and Enterprise users, with community reports of agents autonomously completing a two-week Linux kernel improvement cycle. Claude is gaining significant financial services traction, with Business Insider reporting Wall Street adoption is accelerating, and developer sentiment is visibly shifting toward Claude as developers frustrated by OpenAI's model retirement churn evaluate it as a primary alternative.
