GPT-6 Luna landed two weeks ago at $0.10 / $0.50 per million tokens. Anthropic matched that price exactly, then came in with better numbers. Haiku 4.5: $1 input / $5 output per million tokens Haiku 5.5: $0.10 input / $0.50 output (prompts up to 100k) GPT-6 Luna: $0.10 input / $0.50 output Same price as GPT-6 Luna but: – Terminal-Bench 4.0: 39.2% vs 16.4% – FrontierCode: 46.4% vs 42.4% I love the small model race more than the frontier now!
