This week is interesting. We’re getting a lot of models: Opus 5.5, GPT-6 Sol, Luna, Gemini 4 Pro, Grok 4.7. My guess after seeing leaks and tests: Opus 5.5 will mog Astra, and it’s way cheaper too. Gemini 4 Pro can be Fable 5.1 level and more cost efficient than other models. This is Google’s comeback. Sol can be near Fable 5 level, and cheaper. Grok 4.7 can be delayed again.
