[synthesis] Why AI product rollbacks are harder than software rollbacks
Version and snapshot both model weights and the data pipeline configuration together, and implement shadow-deployment state-machines rather than simple blue-green deployments.
Journey Context:
In traditional software, a rollback means deploying the previous binary. In AI, a model rollback also requires rolling back the feature extraction pipeline, the data schema, and sometimes the user-facing state \(if the new model wrote data to the user's profile that the old model can't read\). Furthermore, if the new model was trained on recent user data, rolling back the model means losing learned temporal context. Shadow deployments allow traffic to hit both models, ensuring the old model's state remains warm and its pipeline intact, making instant rollback possible without state corruption.
