DeepInfra
Pros
- + Per-token pricing sits at the market floor: DeepSeek-V4-Flash-0731 at $0.06/M input and $0.18/M output at time of writing (deepinfra.com/pricing)
- + Cached-input discounts halve prompt-heavy costs automatically — DeepSeek V3.2 served cached prefixes at $0.13/M versus $0.26/M standard in my runs
- + Batch endpoint takes 1,000 requests per call at 50% off with 24-hour delivery, which I found ideal for classification and evaluation sweeps
- + Migration is a base-URL swap: my existing OpenAI client called DeepSeek-V3.2 on the first attempt with no adapter code
- + Financially credible for a budget provider: $107M Series B in May 2026 with NVIDIA and Samsung Next participating
Cons
- - Rate limits are enforced but not published; the 200-concurrent-request ceiling surfaced in third-party trackers, not vendor docs
- - Onboarding credit reporting conflicts across sources ($1, $5, or none) and the vendor pricing page does not settle it
- - No published SLA or managed routing on the serverless tier — model deprecations and repricing are your problem to absorb
- - Output pricing at the top of the catalog is steep (Kimi-K3 at $14.25/M output), so uncapped generation gets expensive fast
- - Catalog is overwhelmingly open-weight models; teams needing proprietary frontier models still need a second provider
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
