Amazon Bedrock
Pros
- + Widest model catalogue I track: Anthropic, Meta, Mistral, Nova, Gemma, MiniMax, Moonshot, GLM, Grok and OpenAI variants behind one API
- + Flex tier at 50% off standard and batch inference at 50% off let me halve a summarisation bill without changing models
- + Standard/Priority/Flex tiering is a bigger cost lever than model choice in the workloads I costed
- + Guardrails blocked the obvious injection and harmful-content probes in my red-team pass
- + Inherits IAM, VPC endpoints, KMS and AWS compliance scope, so security review is a conversation about configuration, not a new vendor
Cons
- - Pricing is a provider-by-region-by-tier matrix; Nova Micro alone ranges $0.035 to $0.040 input across regions and GLM 5 $1.00 to $1.55
- - No free tier documented on the pricing page — experiments bill from the first token
- - Guardrails missed a subtle document-embedded instruction attempt in my testing; they are a filter, not a policy engine
- - AgentCore-style services meter by hour and operation, so idle agents with warm state accrue cost (corroborated by an AWS Builder Center analysis)
- - Regional model availability is uneven; several newer model families serve only a few regions
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
