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
Claude
Pros
- + Long-document analysis with section-level citations; declined to resolve ambiguous clauses instead of guessing in my 140-page test
- + Claude Code on every paid plan turns Max into a real developer tool purchase — multi-file refactors with test iteration
- + Editing behaviour preserves specific facts and asks before cutting clauses; the most trustworthy writing partner I test against
- + 1M-token context on current models (per Anthropic's support docs) removes chunking workflows for large cases
- + Plan ladder (Free/Pro/Max/Team/Enterprise) gives individuals and 2-150 person teams real choices without overbuying
Cons
- - No image generation and no meaningful voice output — a real gap versus ChatGPT
- - Pro usage windows (5-hour sessions with weekly caps) gate exactly the heavy users who benefit most
- - Team requires 2 seats minimum, card-only payment, prorated mid-term adds and no annual prepay refunds
- - Enterprise's $20/seat + API-rate usage model makes bills scale unpredictably without spend caps
- - Model and plan names change often; plan-to-feature mapping needs rechecking at renewal
