Azure OpenAI Service
Pros
- + Global Standard per-token prices match OpenAI's own rates exactly — I verified GPT-5 at $1.25/$10.00 per 1M in my billing
- + Deployment taxonomy (Global, Data Zone, Regional, Batch, Flex, Priority, PTU) lets me buy latency and residency deliberately instead of by accident
- + Batch deployments halve token costs for offline workloads; cached input on GPT-5 at $0.125/1M cut my retrieval pipeline input spend sharply
- + Entra ID, Private Link, customer-managed keys and configurable content filters satisfied a security review that a direct API key never would
- + Microsoft states prompts and completions are not used to train OpenAI models, which closed a procurement question early
Cons
- - No free tier on the pricing page; newer models can require an access application with expected volumes before any deployment
- - Data Zone and Regional deployments price above Global Standard, so residency is a real cost line, not a checkbox
- - The Azure portal is unforgiving: deployment quotas, region availability and RBAC misconfiguration cost me hours in a locked-down tenant
- - Higher median latency on Regional deployments in my parallel tests versus Global Standard at the same model
- - Model naming and rollout cadence (GPT-5.6-sol/terra variants, GPT-6.x trackers) make it easy to budget against the wrong SKU
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
