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
ChatGPT
Pros
- + Broadest multimodal surface in the category: text, reasoning, images, voice, video and agents in one subscription
- + Plus at $20/month is still the value anchor — my mixed weekly workload ran without visible caps
- + Deep research produced a 12-source competitive scan in about 8 minutes (two citation fixes needed, structure worth keeping)
- + GPT/connector ecosystem covers odd-shaped needs that no competitor matches
- + Business seat-type mixing (Standard + one Premium) is a sensible team pricing pattern
Cons
- - Free, Go, Plus and Pro conversations train models unless you opt out; no SOC 2 or SSO below Business
- - Caps downgrade silently to weaker models — quality drops without a warning
- - Ads now run on Free and Go in the US, including on a paid tier (Go)
- - Pro ladder ($100/$200/$500) buys capacity, not capability, with no annual discount anywhere in the lineup
- - Editing temperament drifts to confident verbosity; citations overreached sources in my deep research run
