xAI Grok
Pros
- + Live web plus timestamped X citations gave me source coverage on a breaking story that conventional search engines had not indexed yet
- + Cached input at $0.50/1M on grok-4.7 cut my repeated-prompt agent loop cost by roughly 70% versus uncached billing in my runs
- + The $30 Premium tier bundles SuperGrok, Cursor Pro and X Premium+ that xAI says previously cost $90 combined
- + Multi-agent mode exposes each sub-agent's reasoning chain, so the merged answer is auditable rather than a black box
- + One API covers text, images, video and voice: stills from $0.02/image and video from $0.02/second on the lightest tiers
Cons
- - Billed cost doubles past 200k input tokens on grok-4.7 ($2.00 to $4.00/1M input), a cliff I tripped with a 240k-token upload
- - X-sourced citations included two unsourced low-follower claims that Grok folded into its summary without flagging
- - Loose content policy and X corporate ownership make it a poor default for regulated or customer-facing brand work
- - Plan packaging changed on 12 October 2026 (The X Subscription), so pricing guides written before then, and some SuperGrok pages, disagree
- - No provisioned throughput or reserved capacity option; only the $100 Super tier advertises priority access at peak times
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
