Summary

Anthropic and OpenAI have achieved product-market fit for their coding and general-purpose agent products, Claude Code/Cowork and Codex, evidenced by aggressive enterprise pricing shifts and surging revenue. As of April 2026, both companies transitioned enterprise plans to API token usage pricing, eliminating previous deep discounts. Anthropic's plan now costs \$20/seat/month plus API usage (reported April 14, 2026, effective November 2025), while OpenAI made similar changes on April 2 and April 23, 2026. New frontier models like GPT-5.5 (2x GPT-5.4) and Opus 4.7 (~1.4x Opus 4.6) also launched in April with higher API costs. This strategy is driving significant revenue, with Anthropic rumored to hit \$10.9 billion in Q2 and potentially achieve its first profitable quarter. The labs are expanding enterprise sales teams, and even "AI-failure" stories, like Uber maxing out its 2026 AI budget, are interpreted as signs of strong demand, further supported by Anthropic's \$1.25 billion per month deal with SpaceX for compute capacity.

Key takeaway

For Directors of AI/ML evaluating LLM investments, recognize that frontier models like Claude Code and Codex now command premium enterprise pricing, reflecting their proven utility in professional workflows. Your teams' usage will likely incur API token costs, not discounted rates, as of April 2026. Budget for this increased spend, and rigorously quantify productivity gains from agent adoption to justify the higher expenditure. Be prepared for significant LLM bills, as these indicate successful integration and value creation.
