OpenAI Unveils GPT-6 'Sol' and 'Luna' With API Prices Halved

In one line: OpenAI has reportedly released two new GPT-6 models, Sol and Luna, and cut API pricing to about half that of the prior generation.

Key points

• OpenAI is said to have introduced two models — 'Sol' and 'Luna' — under the GPT-6 line.
• The headline change is API pricing, reportedly down roughly 50% versus the previous generation.
• Both models were reportedly published alongside benchmark performance figures.

Why it matters

If the price cut holds up, inference costs for services built on GPT models drop by half overnight, changing the economics of high-volume and agent workloads that were previously shelved over cost. It signals a shift in the model race from raw capability toward unit price.
