OpenAI, Anthropic cut AI model costs as price-performance race intensifies
50% price cut on GPT-6 Sol and Luna. Anthropic drops Claude Opus 5.5 costs 40%. The frontier labs are now competing on inference efficiency, not raw capability — and it changes the calculus for every enterprise AI budget.
Why it matters
