Things to consider when picking between GPT for Gmail and Stable Beluga 2

  1. Year-one cost, not month-one cost. Multiply by 12 and add any usage-based fees. Vendors often quote a low entry tier; the realistic cost at your usage level can be 3-5× higher.
  2. Where does the data live? If your inputs are sensitive — client work, regulated industries, personal data — check each vendor's data handling, training-on-customer-data defaults, and where the actual servers are hosted.
  3. Integrations with the tools you already use. "Has an API" is the floor, not the ceiling. Look for native integrations with your CRM, IDE, ticketing system — whatever you actually live in day to day.
  4. Lock-in cost. How much work to export your data and move on? Even paid tools can be cheap to leave if exports are clean; some "free" tools are expensive to exit because everything is locked in their format.
  5. Support quality. Read the last few months of the vendor's community forum or support replies. Speed and clarity of support is what you'll lean on when something goes wrong at 2am.

No tool wins on every axis. The right pick is the one whose strengths align with your two most painful constraints.
