Baseten
Pros
- + Truss packaging (weights + model.py + config.yaml) gave me a deployable endpoint I could version in git like any other service
- + Scale-to-zero is real: my idle test endpoint stopped billing entirely between requests
- + Rolling deployments kept the old replica serving during promotion — zero dropped requests in my test
- + SOC 2 Type II and HIPAA compliance included on the base tier (baseten.co/pricing)
- + Per-minute GPU pricing is published: H100 80GB at $0.10833/min, T4 from $0.63/hr at time of writing (inferencehub.org)
Cons
- - An always-on H100 replica at list computes to roughly $4,680/month — min_replica choices dominate your bill
- - Model APIs cover open-weight models only (17 as of October 2026); no GPT or Claude access
- - Dedicated compute, priority GPU access, and higher rate limits require the Pro tier
- - Self-hosting, data residency, and custom SLAs are Enterprise-only
- - No path for non-engineers: everything assumes you can package a model and reason about replicas
OpenAI API
Pros
- + Lowest false-call rate on my 250-case tool-use evaluation, including the deliberate no-call cases
- + Single account covers text, reasoning, image, audio, transcription, embeddings and agent tooling
- + Framework integrations were config-only where rival providers needed adapter code I had to maintain
- + Official pricing page documents wrinkles (residency uplifts, Fast mode rename) that others bury
- + Streaming response times were consistent enough over a week of monitoring that I stopped tracking them
Cons
- - Tool metering ($10/1k search calls, $2.50/1k tool calls) became about a fifth of my search-heavy prototype's bill
- - Entry rate limits are tight; my batch job triggered a 429 burst until spend tier rose
- - 10% uplift on regional data-residency and FedRAMP endpoints adds to an already premium price list
- - Specialised model lines (Rosalind trusted-access, cyber tier) assume institutional buyers
- - Catalogue churn makes third-party tutorials stale within months
