Hidden Costs Breakdown

1

Serverless Inference Pricing Premium vs. API Alternatives

high addon

Vast.ai's serverless per-minute AI model inference is significantly more expensive than dedicated API pricing from providers like OpenRouter. Community users report paying $0.30/minute ($18/hour) for serverless model access, which can far exceed the cost of equivalent API-based inference for common models.

vast offers serverless per minute AI models so checking it for something like https://vast.ai/model/deepseek-v3.2-exp or even glm 3.6 basically every of these turns out to be $.30 cents/minute or 18$ per hour

2

Interruptible Instance Interruption Loss

medium overage

The lowest-cost Interruptible tier can be preempted at any time by higher-priority bids. Work that has not been checkpointed is lost, and users effectively pay for compute time that does not complete. Workloads without robust checkpointing can see significant wasted spend.
