Anthropic API
Pros
- + Definition and cross-reference fidelity in a 180-page contract test beat two rival APIs I benchmarked the same prompt against
- + Schema-valid structured output in 19 of 20 ambiguous-input runs; the twentieth asked rather than guessed
- + Prompt caching cut my repeated-call costs by roughly 70% with a 40K-token cached prefix
- + Explicit long-context and US-only inference pricing tiers instead of hidden multipliers
- + Batch API halves rates again for asynchronous workloads
Cons
- - Top models run $20-$50 per million output tokens, and agent loops are output-heavy
- - No image generation endpoint at all
- - Not the latency leader — open models on fast-inference clouds are several times quicker for short prompts
- - 1M-token context is model-dependent and priced at a steep premium on the tiers that have it
- - Fast model turnover means unpinned model IDs will eventually break in production
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
