The short version

Grok 4.7: xAI's latest update keeps the same price as 4.6. It's a capable general model, but it falls well behind the leaders on agentic coding.

GPT-6 Sol: OpenAI's everyday workhorse. Sol brings Astra-style improvements to a much cheaper tier, and OpenAI says it makes about half as many mistakes as GPT-5.6 Sol.
