OpenAI is reportedly prepping significant cuts explicitly to win developers back from Anthropic, whose Claude Code went viral and helped drive Anthropic's first profitable quarter (The Decoder). Anthropic reversed an unpopular billing overhaul; Claude Fable 5 launched June 9 at $10/$50 per million input/output tokens, double GPT-5.5's $5/$30. With both companies heading toward public listings, a price war pressures margins exactly when IPO investors are scrutinizing them. Good for builders short-term. Watch whether the cheaper tier comes with rate-limit or quality strings attached.
