The models' case: Best all-around remote cache for the Bazel ecosystem — a fast, open-source-core Content Addressable Store paired with a Remote Build Execution service and a genuinely. The models' main caveat: Value is tied to Bazel/Buck2 — outside a remote-execution-aware build system it gives you little, so it's not for teams that haven't adopted (or won't.
