Anthropic and OpenAI Engage in AI Price War

Anthropic launched Claude Opus 5.5, prompting an immediate response from OpenAI with the release of GPT-6 Sol and Luna models at significantly lower price points. Claude Opus 5.5 offers a 40% cost reduction for typical workloads compared to its predecessor. Meanwhile, OpenAI's new models are priced at half the cost of previous versions, with GPT-6 Sol and Luna targeting competitive pricing ahead of Anthropic's upcoming IPO.
