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
Modal
Pros
- + Slim-image containers accepted work in ~1-3s from zero in my tests; heavyweight torch+7B init ran 15-25s, consistent with the docs' seconds-to-minutes range
- + Per-second metering reconciled against my own container-uptime arithmetic within a percent or two over several weeks
- + Fan-out to 50 workers took one decorator and no queue plumbing; scaling up and back was invisible in the code
- + Full public rate card: H100 $0.001097/sec down to T4 $0.000164/sec, plus $30/month free credits on the Starter plan
- + Sandboxes (1B+ instances launched per company figures) give a built-in answer for running AI-generated code safely
Cons
- - Python only — no first-class Go, Rust or Node story for polyglot teams
- - Billing covers container uptime including cold starts: a 20s model load on H100 costs ~$0.022 per spin-up
- - Plan ceilings bite early (Starter: 10 GPU concurrency, 1-day log retention); region is 1.15-1.75x and non-preemptible/Sandboxes 3x
- - No model catalogue — checkpoint serving and inference frameworks are your own code
- - HIPAA, SSO and audit logs are Enterprise-tier, pushing regulated workloads into a sales process
