Unlimited AI API — predictable cost, unlimited usage

Most AI APIs charge per token, which means your bill scales with usage. That's fine for prototyping, but at production scale it becomes unpredictable. A single bad prompt loop can spike your bill 10x overnight.

Plugsky's self-serve plans are unlimited on every model in your tier, billed by the month. You commit to the price, we commit to unlimited usage.

Why unlimited matters

• Predictability: you know the bill before you ship. No meter, no surprises.
• No "free tier that throttles at peak." Real production traffic, not toy demos.
• Encourages innovation: when every call is metered, teams avoid experimentation. When calls are unlimited, teams iterate faster.
• Better unit economics at scale: once you're past ~20M tokens/month, flat pricing is cheaper than per-token on every public AI vendor.

What's included in each tier

Every plan is truly unlimited monthly usage — no token meter, no throttling, no surprise bills. The only cap is the requests-per-minute rate limit, which scales with the plan.

Plan	Monthly	Models in tier	Token usage / month	Rate limit (req/min)
Starter	$20	micro → pro	Unlimited	60
Builder	$60	+ max, vision	Unlimited	300
Scale	$120	+ frontier, reasoning	Unlimited	1,000

What's "unlimited"? Use as many tokens as you want per month — the only cap is the requests-per-minute rate. What's the rate limit? How many API calls you can make in one minute (returns 429 with Retry-After if you hit it). Embeddings, RAG queries, and agent runs all share the same unlimited pool — no add-ons, no per-feature pricing.

When per-token is better

Per-token pricing beats flat pricing only at very low usage. If you're under ~5M tokens/month, you're probably better off on plugsky-micro (free) or the $20 Starter plan with the same effective economics.

Past 50M tokens/month, flat pricing on Plugsky Builder ($60) saves you 60-90% vs. OpenAI gpt-4o for the same workload. Use the calculator for your exact numbers.

Frequently asked questions

Is there really no per-token meter?

Correct. On self-serve plans (Starter, Builder, Scale), you can call the API as much as you want. The only cap is the rate limit (60, 300, 1000 req/min).

What about embeddings and RAG?

Same — unlimited on every plan. Embeddings, RAG queries, agent runs, and tool calls all share the same flat pricing.

What if I exceed the rate limit?

You get a 429 with a Retry-After header. Upgrade to the next tier for higher rate limits, or contact sales for custom limits.

Is there a fair-use policy?

Yes — self-serve plans have a fair-use rate limit (no abuse, no scraping). The rate limit per tier is the only cap. Enterprise contracts have custom limits.
