OpenAI and Anthropic Release New Models
Anthropic and OpenAI both dropped new models, and the interesting part isn’t just that they’re better — they’re getting a lot cheaper too. Anthropic’s Claude Opus 5.5 is aimed heavily at coding, enterprise work, finance and other complex agentic tasks.Anthropic says it beats GPT-6 Astra on some coding benchmarks and follows instructions more reliably. It’s also cheaper than the previous Opus generation at $4/M input tokens and $20/M output.
OpenAI launched GPT-6 Sol and GPT-6 Luna, using similar training techniques to GPT-6 Astra. Sol costs $2/M input and $10/M output, while Luna is dramatically cheaper at $0.10/$0.50. OpenAI says Sol produces about half as many factual errors as its predecessor. It also claims coding performance around Claude Fable 5.1 levels while costing less.
Feels like the next big AI race is going to be who can deliver near-frontier intelligence at commodity prices.
