Weights & Biases
Pros
- + Instrumenting a PyTorch loop took about ten lines and gave me usable loss curves, system metrics and sweeps within minutes
- + Free tier genuinely works for personal projects: 5 seats, 5 GB storage, and experiment tracking plus Weave tracing at $0
- + One account covers classic training runs and LLM tracing/evaluation via Weave, so I did not need a second vendor for the eval project
- + Artifacts with lineage let me version datasets and models and reconstruct which data produced which checkpoint
- + The 30 September 2026 CoreWeave Forge sign-in migration was a non-event in my account — credentials, projects and runs carried over
Cons
- - Weave ingestion overage at $0.10/MB on Pro punishes verbose LLM logging; my evaluation project blew through the 1.5 GB/month inclusion
- - Pro plans are capped at organisations under 50 employees — a growing client was moved to an Enterprise conversation mid-project
- - Four metered dimensions at once (seats, storage, ingestion, inference) make bills hard to forecast without instrumentation
- - Enterprise is quote-based with self-serve pricing stopping at Pro, so the step-up is a sales process
- - Pre-acquisition pricing write-ups (per tracked-hour tiers) are now stale and mislead buyers comparing quotes
Hugging Face
Pros
- + Largest open model ecosystem anywhere: 2.96M public model repos and 1.44M Spaces as of the summer 2026 State of Open Models report
- + Real free tier: unlimited Hub hosting, free CPU Basic Spaces and ZeroGPU GPU quota at $0
- + Transparent, itemised pricing — GPU hours ($0.40/hr T4, $2.50/hr A100) and storage ($12/TB public) are published to the cent
- + Dedicated Inference Endpoints start at $0.033/hour with no cold starts, and the deployment quote matched the pricing table in my check
- + PRO at $9/month packs 8× ZeroGPU quota, queue priority and $2 monthly inference credits
Cons
- - Bought by NVIDIA for $12.93B (announced 2026-09-03); the multi-vendor neutrality is a promise, not a guarantee
- - Four separate meters (seats, storage, compute, inference) make real costs hard to forecast from the plan price alone
- - Free-tier inference is queue-bound on popular models exactly when a demo matters
- - Assumes git, Python and model-format fluency — no guided path for beginners
- - Enterprise gating (SSO, governance) sits at $50/user/month
