Kingy AI Take

GPT-6 Sol merits a workload-specific trial when Astra costs more than the task warrants. Kingy's September 22 comparison finds lower cost per task on OpenAI's reported tests, while noting that Sol's top scores trail GPT-5.6 Sol on DeepSWE and OSWorld 2.0. Those scores are vendor-reported, not Kingy hands-on results.

Who it is for

Developers

What feels promising

The model gives developers another price and capability point for sustained coding and agent tasks. Its value depends on the workload and reasoning effort; vendor evaluations do not establish a universal winner.

What feels unproven

OpenAI's launch-day benchmark figures are vendor-reported and may differ from production ChatGPT output. GPT-6 Sol is not the highest-scoring model on every reported task. Availability may vary during the gradual rollout.
