Frontier AI keeps racing despite calls to slow down
Anthropic and OpenAI debut Opus 5.5 and GPT-6 Sol and Luna
Despite calls from AI employees to slow down the pace of development, major model releases continue at a rapid rate. This week, Anthropic and OpenAI each unveiled new versions of their Claude and GPT models. Anthropic's Opus 5.5 and OpenAI's GPT-6 Sol and Luna arrived just 19 days apart. Anthropic's CEO Dario Amodei, echoing the concerns of AI staff, emphasized the need to pace the advancement of AI capabilities.
Opus 5.5, Anthropic's latest model, is touted as the strongest-performing model tested, with a notable improvement in software tasks and reduced costs. It is also cheaper than its predecessor, with lower input and output token prices. OpenAI's GPT-6 Sol and Luna, while more expensive in promotional pricing, offer significant cost savings through improved caching and inference.
Both companies claim their models improve alignment and safety, though Anthropic's defenses are partly aimed at protecting its business from competitors.
