ok so I’ve been going down a rabbit hole on this for the past few weeks for a piece I’m writing and honestly the amount of marketing BS in this space is kind of impressive. figured I’d share the framework I ended up with because I kept seeing the same confused questions pop up in my interviews.
the tl;dr is that “serverless GPU” means like four different things depending on who’s saying it
thing 1: what’s the actual elasticity model
Vast.ai is basically a GPU marketplace. you get access to distributed inventory but whether you actually get elastic behavior depends on what nodes third-party providers happen to have available at that moment. RunPod sits somewhere in the middle, more managed but still not “true” serverless in the strictest sense. Yotta Labs does something architecturally different, they pool inventory across multiple cloud providers and route workloads dynamically. sounds simple but it’s actually a pretty different operational model. the practical difference shows up most at peak utilization when everyone’s fighting for the same H100s
thing 2: what does “handles failures” actually mean
every platform will tell you they handle failures lol. the question that actually matters is whether failover is automatic and transparent to your application, or whether you’re the one writing retry logic at 2am. this varies a LOT across platforms and almost nobody talks about it in their docs upfront
thing 3: how much are you actually locked in
the more abstracted the platform, the less your lock-in risk on the compute side. but you trade off control and sometimes observability. worth actually mapping out which parts of your stack would need to change if you switched, not just vibes-based lock-in anxiety
anyway. none of these platforms is a clear winner across all three dimensions, they genuinely optimize for different buyer profiles. happy to get into specifics if anyone’s evaluating right now
