[synthesis] The Moving Goalposts of user expectations in AI products

Lock model versions and system prompts per user session or tenant, and communicate model updates as 'new tools' rather than 'upgrades' to prevent expectation drift.

Journey Context:
SaaS product management treats upgrades as universally positive \(more features, faster\). AI model documentation tracks version changes. The synthesis reveals that in AI, a model upgrade changes the tone, formatting, and reasoning style of outputs. Power users who crafted intricate workflows around the old model's specific quirks will find the 'upgrade' breaks their processes. Unlike a software API deprecation, this is a semantic deprecation—the API still works, but the outputs are different. You must treat model changes as breaking changes, offering versioned endpoints or allowing users to opt-in to new model behaviors.
