Reactions to GPT-6 Sol are very mixed so far. On the one hand, the pricing is great. No doubt about that. But there’s also quite a bit of negativity around its performance. In benchmarks and real-world coding, it seems nowhere close to Astra or Opus 5.5, despite OpenAI’s claims. Is it just a souped-up Terra model after all?
