Claude Opus 5.5, GPT-6 Sol, GPT-6 Luna, and a new price war
Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.
GPT-6 Luna is now priced at just $0.10/$0.50 per million tokens, making it one of the cheapest high-performance models available. This drastic cost reduction enables scalable deployment of agentic workflows and conversational applications without significant budget constraints, forcing competitors like Anthropic to lower prices to remain viable.
GPT-6 Luna just dropped to $0.10/$0.50 per million tokens—half its predecessor and roughly one-tenth of Claude Haiku 4.5—making it one of the cheapest capable models OpenAI has ever shipped, while Opus 5.5 cut prices 20% ($4/$20) and slashed cache reads 60%. If you're running high-volume app backends or long agentic loops, re-benchmark now: the cheap tier just got dramatically cheaper, cached-context agents get materially cheaper on Anthropic, and models like GPT-5.6 Terra no longer have any pricing rationale.
