The short version

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.

Gemini 3.1 Pro: Google's Pro-tier model, still labelled a preview. It's a solid all-rounder, but it's starting to look dated next to Google's own fast-moving Flash line.
