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 published fair-use limits 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 published fair-use limits 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.
