Most AI API pricing is "per million tokens." That sounds fair until you realize a single bad prompt can spike your bill 10x, and you have no way to forecast cost without first building a metering layer.
Plugsky's self-serve plans are flat monthly. You pay one number, you get unlimited usage on every model in the tier. Enterprise plans are annual contracts with custom rate limits.
How Plugsky AI API pricing works
Two tiers, one decision:
- Self-serve — flat monthly, no per-token meter, cancel anytime. You commit to the price; we commit to unlimited usage on every model in your tier.
- Enterprise — annual contract, custom rate limits, dedicated capacity, SLA, on-prem options, audit export.
Self-serve plans compared
| Plan | Monthly | Annual (-20%) | Models | Rate |
|---|---|---|---|---|
| Trial | $5 / 7d | — | plugsky-micro | 60/min |
| Starter | $20 | $16 | micro → pro | 60/min |
| Builder | $60 | $48 | micro → max, vision | 300/min |
| Scale | $120 | $96 | + frontier, reasoning | 1,000/min |
Enterprise and custom contracts
For annual contracts with custom rate limits, dedicated capacity, and on-prem deployment:
- Starter Enterprise — from $15K/year, 5 seats, 99.9% SLA, DPA included
- Growth Enterprise — from $50K/year, 25 seats, Slack channel, SAML SSO, DPA + SOC 2
- Enterprise — from $150K/year, unlimited seats, named engineer, DPA + SOC 2 + HIPAA
- Sovereign AI Cloud — from $500K/year, air-gapped deployment, FedRAMP, 24/7 + dedicated CSM
Cost vs. OpenAI and Anthropic
For a team doing 50M input + 25M output tokens/month on GPT-4o, the OpenAI bill is around $500/month. On Plugsky Builder, the same workload is $60/month — and the Builder tier also gives you plugsky-max, plugsky-vision, and plugsky-reasoning included.
For very large workloads (10B+ tokens/month), the math shifts in favor of self-hosted or enterprise contracts. Use the OpenAI cost calculator to model your specific numbers.
Frequently asked questions
Is there a free tier?
We have a $5 / 7-day trial that gives you access to plugsky-micro. Beyond that, all our pricing is flat monthly — no free tier because free tiers throttle at peak.
What happens if I exceed my plan?
You don't. Self-serve plans are unlimited on the models in your tier. If you hit the rate limit, you get 429s with a Retry-After header.
Can I switch plans mid-month?
Yes. Upgrade takes effect immediately and you're charged the prorated difference. Downgrade takes effect at the next billing cycle.
Do you offer non-profit or academic pricing?
Yes — contact sales@plugsky.com with your .edu or non-profit verification.
