The decision, in plain words

For a solo builder at 50 H100-class GPU-hours/month and a $50.00/mo budget for the GPU cloud slot, Modal leads at 50% fit and $197.50/mo. The two rules doing the work: batteries included (Bundles per-second billing, recurring free credits — fewer services to glue at team size 1); scale-to-zero (Serverless — you pay busy time only, idle costs nothing).

RunPod Serverless runs close (46% fit, $227.50/mo). It takes the lead if serverless — you pay busy time only, idle costs nothing matters more to you than the current weights assume.

Honest weak spot of the pick: ~$197.5/mo is 395% of your $50/mo budget — over it.

Generated from the calculation above — every number traces to the sourced data; nothing here is written by an AI making things up.

Why Modal scores 50%

Budget fit (weight 30, our estimate) — ~$197.5/mo is 395% of your $50/mo budget — over it-30
Batteries included (weight 12, our estimate) — Bundles per-second billing, recurring free credits — fewer services to glue at team size 1+12
Exit cost (weight 4, our estimate) — Standard containers move easily, but queueing/autoscale config is platform-specific+0.4
Ecosystem maturity (weight 8, our estimate) — established — our estimate from ecosystem age, docs and hiring pool+8
Scale-to-zero (weight 10, our estimate) — Serverless — you pay busy time only, idle costs nothing+10
Total (lines sum exactly)0.4
Possible range −64…+64 (sum of active rule weights) · fit % = (total + max) / (2 × max)(0.4 + 64) / 128 = 50%
