Matthew Berman's Hands-On With GPT-5.6: Testing OpenAI's New Flagship a Week After GA
Matthew Berman's GPT-5.6 review puts OpenAI's new Sol-led family (GA July 9) through practical coding and reasoning tasks, giving builders a concrete read on where the flagship actually improves versus the benchmark claims. It's useful as an independent, task-driven counterweight to OpenAI's own state-of-the-art framing, especially on token efficiency and everyday coding. Pair with the cross-lab comparisons to decide whether Sol, Terra, or a rival is worth switching to.
