TL;DR

GPT 5.6 Sol works best for tasks that need several steps, clear decisions, and a strong first result. It costs more than Terra and Luna, so it suits important work better than simple drafts.

The five tests covered slide design, lead research, website building, PDF form completion, and a multi-model review. Sol handled each task with little guidance and made useful choices during the process.

The outputs still needed checks. Lead data required verification, form alignment needed review, and project rules had to match the code, tests, and documentation.

Key points

  • Important fact: Sol cost about $0.90 in the presentation test, compared with $0.37 for Terra and $0.29 for Luna.

  • Common mistake: Don’t use Sol’s output without checking facts, files, and formatting.

  • Practical takeaway: Use Sol for multi-step work and cheaper models for quick tasks.
