    "Review of GPT-5.6 Sol"

    5 out of 5 stars Posted 2026-07-09

    Pros: GPT-5.6 Sol feels like the model I would reach for when the task is actually hard. As a developer, I like that it is built for deeper reasoning, coding, long-horizon planning, and agentic workflows instead of just quick prompt-and-response work.

    It is especially appealing for complex debugging, multi-step code changes, research-heavy engineering tasks, and agents that need to coordinate tools without losing the plot. The fact that OpenAI is positioning Sol as the most capable model in the GPT-5.6 family makes sense, because this is the one I would want for serious engineering work.

    Cons: The main downside is that Sol is the premium option, so I would not use it for every single task. OpenAI lists Sol at a higher token price than Terra or Luna, which means developers will still need to be smart about routing simple jobs to cheaper models.

    Overall: Five stars from me. GPT-5.6 Sol looks like the best fit for developers building advanced coding agents, automation systems, and serious software engineering workflows. It is the model I would use when quality, reasoning, and reliability matter more than shaving every cent off the run.
