See how long AI-agent context can affect cost.
Pick a context shape and a model price tier. This simulator shows the before/after token path, estimated input-cost savings, context-handling notes, and added Zerix latency with transparent illustrative math.
Illustrated request path
Direct call vs. Zerix-prepared request
Zerix prepares only what is safe to compress.
Code and must-keep evidence are preserved; noisy prose is condensed into grounded context.
Simulator inputs
These controls never call Zerix, a provider, billing, or signup. They only run deterministic browser math.
This text stays in your browser. The simulator does not send it to Zerix or any model provider.

Higher-priced frontier tiers produce higher dollar savings from the same token reduction because every removed input token avoids a more expensive downstream model call.

Transparent math
tokens saved = input tokens - after-Zerix tokens.
cost saved = tokens saved / 1,000,000 x selected tier input price.
monthly saved = cost saved per request x monthly request total.
What stays faithful
Tool outputs, user decisions, constraints, names, dates. Zerix prepares repeated material with care while protecting material that cannot be allowed to drift.
This page processes custom text locally in your browser and makes no network request. Use the signed-in dashboard only when you want a live request receipt.
All numbers on this public playground are illustrative and simulated. They are not benchmark attestations, provider quotes, production receipts, or guarantees. Real Zerix responses expose request-specific metrics after signup: input tokens, presented tokens, tokens saved, quality score, tier used, latency, and billing receipts.
