Anthropic and OpenAI reportedly cut costs with new AI models
A post claims 40% lower running costs for Anthropic's Opus 5.5 versus the prior generation. Its author argues that cheaper AI sits uneasily with the companies' warnings about its risks.
TLDR
A September 23, 2026 post claims Anthropic introduced Opus 5.5 and OpenAI released GPT-6 Sol and Luna the previous day. It lists input/output prices per million tokens of $4/$20 for Opus 5.5, $2/$10 for Sol and $0.10/$0.50 for Luna, saying Sol's prices are half its predecessor's. The author argues that competition from Chinese open-weight models and pressure to grow help explain the pricing push, and questions the tension between calls to slow AI development and efforts to sell it more widely.
