AI agents must plan for model deprecation, not dynamic routing

The author argues that AI agents should be designed with the understanding that their underlying models will eventually be deprecated or shut down, a failure mode often underestimated by development teams. Instead of dynamically routing requests to different models, agents should be pinned to a specific, tested model to ensure consistency. A new open-source tool, modeldeprecations.dev, is introduced to track AI model lifecycles, providing crucial information on active, deprecated, and retired models, including their recommended replacements and shutdown dates, to help teams proactively manage these dependencies. AI

IMPACT Highlights the critical need for proactive dependency management in AI agents to prevent production incidents due to model deprecations.
