What changes the numberThe hardware budget is driven by usage patterns, not hype.
Teams often overbuy because they hear a model name before they define the workflow. In healthcare, the better approach is to size the system around concurrency, retention, uptime expectations, and where the AI sits in the real process.
Concurrency
The biggest swing factor is how many users or workflows need answers at the same time. A low-volume clinic and a large shared service desk have very different inference needs.
Model ambition
Transcription-only setups are lighter than broad document intelligence, RAG, or larger local assistants that must reason over more content.
Retention and storage
Audio retention, document archives, embeddings, logs, backups, and replication can change storage needs quickly even when inference demand stays modest.
Redundancy expectations
Some teams are comfortable with a practical single-node pilot. Others need failover, segmented environments, and stronger uptime guarantees from day one.
