What you don't pay

No API token costs. Ever.

Most AI platforms pass through OpenAI or Anthropic API costs — every conversation eats into your margin. We don't. Atomic Engine runs on our own LLM, trained on our hive, served on our infrastructure. The price you see is the price you pay. Full stop.

Other platforms

Per-token billing

Subscription + per-conversation API charges + overage on busy months + token rate increases when the underlying provider raises prices. You don't know what you'll pay until the bill arrives.

Atomic Engine

Flat subscription

Your monthly tier price. That's the bill. Use it as much as you want within your conversation cap. No per-token charges. No surprise overage. No upstream provider price hikes.

Where Claude comes in

We use Anthropic's Claude for the parts where premier-grade reasoning genuinely matters — complex multi-step decisions and edge cases. The everyday vertical work runs on our own hive-trained LLM. Anthropic margin doesn't hit your invoice because we absorb it strategically only where it adds real value.

The hive opt-in discount

Your contribution
has real value.

The hive is our community-trained LLM. The more conversations contributed (anonymised, GDPR-compliant), the smarter the model becomes — which benefits every member, including you. Because your contribution genuinely matters, we share the value back: 35% off your subscription when you opt in.

Opt in

Default option · 35% off

Your agents' conversations contribute (anonymised) to the hive's training. You benefit from every other member's contributions too. Privacy controls remain — toggle off anytime, request data deletion under GDPR.

Opt out

Pay full price · no contribution

You still benefit from the hive's training (it's our LLM, baked in) but your data stays entirely yours. Some regulated industries need this. We respect it. You pay rack rate.
