Automation platforms are selling model-swappability as the hedge against picking wrong

Zapier published two pieces on 27 July 2026 about running more than one model behind the same automation: one enumerating the models its steps can call — GPT-5.6 Sol, Gemini 3.6 Flash and Opus 5 among them — and one arguing explicitly for model flexibility as protection against lock-in. Both are vendor positioning, but the design point stands on its own: pinning a workflow to a single provider’s model is a commitment you need to be able to unwind.

What it means For a small team the automation platform, not the model, is where switching cost quietly accumulates — so "can I change the model later" is the procurement question that actually binds.
