Anthropic unveils Claude Opus 5.5 with big cost cuts — Anthropic launched Claude Opus 5.5, the first release in its 5.5 lineup, saying it performs similarly to Claude Fable 5.1 on most tasks while costing roughly 40% less to operate than Opus 5. Anthropic calls it the top scorer yet on its internal alignment audit and notes external groups, including Frontier Design and METR, tested the model before release. Anthropic ↗
My takeaway: What a surprise release! Artificial Analysis ranks Claude Opus 5.5 first on its Intelligence Index at maximum effort. It also outperforms Fable 5.1 on several evaluations, including the Coding Agent Index. The most impressive part for me is the cost. Its API token prices are lower than Fable 5.1's, and Anthropic estimates that typical workloads cost roughly 40% less to run than on Opus 5 at default settings. Time to put it through our own evals!
OpenAI rolls out GPT-6 Sol and Luna — OpenAI introduced two lower-cost GPT-6 models for everyday work, with API prices roughly halved compared with their GPT-5.6 promotional pricing. The company reports improved factual accuracy for both models and says Sol approaches Astra’s performance on its internal factuality evaluation. OpenAI ↗
My takeaway: More good news from OpenAI. Like Anthropic with Opus 5.5, OpenAI has released its new models with price cuts. GPT-6 Sol looks particularly promising: at maximum effort, it matches Muse Spark 1.3 on Artificial Analysis's Intelligence Index, with a lower measured cost per task. I have a few use cases for GPT-5.6 Terra, and I think GPT-6 Sol could replace it if it performs well in my evals.
