Anthropic and OpenAI Release Cheaper AI Models in First Launches Since Call for Slowdown
OpenAI introduced GPT-6 Sol and GPT-6 Luna, while Anthropic unveiled Claude Opus 5.5, marking both companies' first major model releases since recent calls to slow AI development.

Anthropic and OpenAI have each released new, lower-cost artificial intelligence models, marking their first major launches since earlier calls within the industry for a slowdown in AI development.
OpenAI introduced two new models, named GPT-6 Sol and GPT-6 Luna, while Anthropic unveiled Claude Opus 5.5. Both releases are positioned as more affordable options compared with the companies' previous flagship models.
The launches come amid continued competition among leading AI developers to offer more accessible tools while managing the substantial computing costs associated with training and running large language models.
The releases follow a period in which some figures in the AI industry had called for a more cautious pace of development, citing concerns about safety and the broader societal effects of rapidly advancing AI systems.
Specific pricing, capabilities and availability details for the new models were not fully outlined in initial reporting on the releases.
