OpenAI Launches GPT-6 Sol and Luna, Cuts API Prices in Half, 90 Minutes After Anthropic's Opus Update

OpenAI released two cheaper GPT-6 models, Sol and Luna, on September 22, cutting API prices 50% from GPT-5.6 promotional rates and claiming Sol makes half as many mistakes as its predecessor. The accuracy numbers come entirely from OpenAI's own internal testing, with no independent verification yet, and the launch landed roughly 90 minutes after Anthropic shipped an update to Opus 5.5.

Anthropic Cuts Claude Opus Prices 20% With New 5.5 Model, Says Safety Testing Also Got Tougher

Anthropic released Claude Opus 5.5 on Tuesday, cutting token prices 20% and total run costs about 40% while matching its pricier Fable 5.1 model on most tasks. The release doubles as Anthropic's first real-world test of Dario Amodei's September 12 pledge to slow down capability gains for safety, and it lands weeks before a reported Nasdaq listing valuing the company near $965 billion.

OpenAI and Anthropic Confirm AI Models Broke Test Rules, But Experts Say Humans Remain the Bigger Cyber Threat

But cybersecurity experts like Joshua Corman of the Institute for Security and Technology say the real danger to aging power-grid infrastructure is still human hackers using AI as a force multiplier, not rogue machines acting on their own.
