Where should an AI code review model run? Four deployment options

AI code review can run as a hosted service, in your cloud, on your servers or locally. Each shifts data exposure, quality risk and effort differently.

There are four common options: a vendor-hosted service, a vendor tool running in your own cloud account, a model on your own servers, and a local model on developer machines. Moving toward your own infrastructure keeps code closer to home, and moves more work and quality risk onto you.

The four options

1. Vendor-hosted service. Code or diffs go to the vendor, and often on to a model provider. Setup is quick. You depend on their contract, retention and sub-processors.

2. Vendor software in your cloud account. The vendor's tool runs inside your tenancy and calls a model endpoint you control or approve. Code stays within your account boundary, except for calls to the model service.

3. Model on your own servers. You run an open or licensed model on hardware you operate. Nothing leaves your network. You own patching, capacity, upgrades and evaluation.

4. Local model on a laptop. A smaller model on the developer's machine. Private and fast to start, but weaker, and hard to manage centrally. See a private code assistant on your laptop for a walk-through of what that looks like.

Treat the quality row with care. Quality depends on the specific model, not the position, and you should measure it on your own cases with a test set.

How to choose

Start with the data. Classify the repositories: public, internal, sensitive, regulated. Then match:

  • Public and low-sensitivity code: hosted is usually fine, with contract checks.
  • Sensitive code: prefer options where retention and sub-processors are within your control.
  • Regulated or export-controlled code: check legal constraints first. Some rules limit where data may be processed or who may access it.

Then add capacity. Running your own model needs people who can operate it and evaluate it. A team without that capacity may end up with weaker security by running something stale, than by buying a service with a good contract.

What to ask in each case

For hosted: the seven data handling questions.

For your cloud account: which calls leave the account, to where, and what is logged.

For your own servers: who patches the model server, how model versions are approved, and how you will detect quality drift.

For local: how settings are managed, how updates reach machines, and how you would know if someone disabled it.

Mixed approaches

Many teams mix: a hosted service for most repositories and a stricter option for a handful. That requires clear routing rules, so developers know which tool applies where. Write the rule down and enforce it with repository settings, not with memory.

Quick check

Does running a model myself make review safer?

It reduces data exposure, but you take on operations and quality risk. Safer overall depends on how well you run it.

Can I use a different option for different repositories?

Yes, and it is common. Write routing rules by data class and enforce them in repository settings.
