OpenAI and Anthropic have significantly reduced the prices of their large language models over a few months in 2026. This trend began with OpenAI's GPT-5.6 Luna and Sol, followed by Anthropic's Claude Sonnet 5 and Opus 5. Both companies introduced new models and adjusted pricing, with notable reductions in cache read costs, which are critical for agentic coding applications. The price cuts, some as steep as 80%, have made using these advanced LLMs considerably cheaper without apparent compromises in output quality. AI
