Update
What changedOpenAI’s GPT-6 Sol and GPT-6 Luna are now available in ChatGPT Work, Codex and the API, with Luna also coming to the desktop app and Free and Go plans. Sol is aimed at complex work such as coding, while Luna targets high-volume tasks with clear outcomes, including summarisation and information extraction.
TechCrunch reports that the new models cost half as much as their GPT-5.6 predecessors for API use. OpenAI also says GPT-6 Sol makes about half as many mistakes as the earlier Sol on its internal factuality evaluation, while claiming lower coding error rates. Those performance claims come from OpenAI, not an independent benchmark, so the price change is firmer news than the alleged leap in reliability.
The practical choice for developers is now model routing: reserve Sol for harder jobs and send routine traffic to Luna, rather than paying flagship rates for every request. OpenAI says the models are already available to most paid ChatGPT accounts through Work and Codex, with a gradual rollout across the main ChatGPT app and website. The useful calculation is cost per successfully completed task, because a cheap model that needs several retries has merely found a more affordable way to waste your afternoon.
Sources and evidence- OpenAI launches GPT-6 Sol and Luna, boasting lower cost and fewer mistakes – TechCrunch: OpenAI launched GPT-6 Sol and GPT-6 Luna as cheaper models for complex and high-volume workloads, with broad availability and company-reported reliability improvements.
