Stable Horde
Pros
- + Completely free with no paywall and anonymous access via the ten-zero API key — in my queue testing, requests completed without an account or a card
- + The kudos economy refuses commodification: priority is earned by contributing compute, cannot be bought, and never expires, which keeps the service open to people with nothing to give back
- + Three worker tiers including Alchemists that run post-processing on CPUs or 2GB VRAM, so hardware-poor users can still earn priority
- + Requests are anonymized before dispatch and workers only make outbound connections — a privacy posture better than most hosted generators
- + Open REST API plus mature open-source clients (ArtBot, horde-worker-reGen, KoboldCpp/Aphrodite bridges) with live status, queue-depth, and throughput stats published
Cons
- - No latency contract: under load, requests time out and the project's own guidance is to retry with different parameters
- - Output quality varies with the volunteer pool and their checkpoints; the trust system polices abuse but not taste
- - No support desk, no SLA, and no paid fast lane even when you would happily pay for one
- - Commercial rights to outputs depend on each underlying model's license, which the service does not settle for you
- - Text generation is limited to whatever models volunteer Scribes happen to serve, a narrower and less predictable catalogue than hosted LLM subscriptions
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
