David decided: Suspected model-routing degradation, with a PE pitch on Monday at stake
David notices Codex's answers degrade in quality and theorises he is being silently routed off the GPT-5.5x-high model he selected. He flags the stakes (presenting to a PE firm on Monday) and demands Codex defend its switch from its earlier recommendation to the Claude Agent SDK rather than acquiesce to vendor framing.
I think your model is being routed to a shitty model ... I'm presenting to a private equity firm on Monday on this product. We really need to take this seriously
