OpenAI Releases GPT-5.6 Sol

The GPT-5.6 family, led by the Sol model, was released following a delay caused by a White House review of cybersecurity risks.

OpenAI CEO Sam Altman said the new models are cheaper and more efficient than previous versions, addressing customer concerns about AI costs.

The launch comes as competition with Anthropic intensifies and as OpenAI prepares for a potential IPO. The company also introduced a 'super app' and a ChatGPT for Work feature to embed AI agents in the workplace.
