#1 Codex Rises, Claude Meters Programmatic Usage Amidst Market Shifts
The AI landscape sees a divergence post-GPT 5.5: Anthropic's Claude gains traction with its growth and CFO, while AI engineers show increasing preference for Codex. Anthropic's shift to meter programmatic usage by linking API credits to subscription plans has drawn criticism, perceived by some as a 'rug pull'. This coincides with OpenAI's enterprise promotions and Codex adopting a more liberal approach. Concurrently, advancements in agent infrastructure and UX are noted, with Cline, LangChain, Notion, and Cursor releasing features focused on long-term state, streaming, and orchestration.
