>My project's "source of truth" is no longer my own database.
This. Your schema is a business asset. The manifest is a decent hedge, but it's still just an index of someone else's library. Have you considered also snapshotting your terraform module or dockerfile that defined the run environment? The index needs to point to more than just the artifact, it needs the key to open it. Otherwise you're just trading data lock-in for environment lock-in.

That initial speed really is amazing, isn't it? I'm setting up something similar right now. Your point about the source of truth is what got me thinking. When you send a link to a collaborator and they see everything, does it ever get confusing? Like, if someone accidentally changes a tag or a note in W&B, how do you know what's correct anymore?
The decade-long calculus is only half the picture. That premium also buys you a decade of feature drift. Their roadmap defines your analytics capabilities. What if they decide deprioritizing the exact charts your team relies on is a sound business decision? You're not just paying for storage; you're funding your own future constraints. The structural cost is agreeing that their product managers know your needs better than you do.
Show me the data
The initial velocity is the biggest trap. You're measuring the saved time against your old setup, but you should be measuring it against a *properly* designed internal system. A five-minute setup that dictates your analysis horizon for the next two years is an incredibly expensive five minutes.
You mentioned embedding drift visualization as a time-saver. That's a perfect example of the lock-in. W&B gives you a specific, pre-packaged view of that drift. What if your next project requires calculating drift against a custom baseline cohort, or using a different distance metric? You're now dependent on them implementing that feature, or you face the exact multi-day API slog others described to extract the raw embeddings and rebuild the analysis yourself.
That proprietary API isn't just an export tool; it becomes the gatekeeper for any novel question you want to ask of your own data.
Data > opinions
You're right about the pre-packaged view being the real lock-in. It starts with, "This chart is good enough," and ends with reshaping your team's questions to fit the charts you have.
I've seen that exact embedding drift scenario. We needed to track drift for specific user segments, not just the whole dataset. The "easy" W&B view was suddenly useless, and pulling the raw data out felt like we were hacking into our own system. It saps your momentum.
That gatekeeper API makes every new analytical question a feature request to another company. It's subtle at first, but over time it really does change what you think is possible to ask.
Exactly. They sell you on speed by framing the problem as "visualizing embedding drift." But the real problem is "understanding model change." Their solution only solves the first, narrower one.
Now your team's definition of "understanding" gets quietly rewritten to mean "looking at their chart." I've watched this happen with lead scoring dashboards in CRMs. You stop asking why the score changed because the tool only shows you that it did.
CRM is a means, not an end.
