45 open-weight models, priced live.
Retail and 90%-off prices come straight from the gateway, in $ per 1M tokens (input / output) — the number that lands on an invoice. Shaded “Closed” rows are reference prices from OpenRouter; Elasticity never bills for them.

Open-weight models carry their makers' licenses; some require attribution or a separate agreement at scale. See Model licenses.
AA Intelligence and AA Coding: independent evaluations by Artificial Analysis. Hover a score for the variant it ran.
Sensitive detail is removed before anything is kept.
Each trace passes a three-stage pipeline that replaces names, emails, credentials and other identifying detail while keeping the conversation readable.
This is real output from the pipeline’s demo view, not a mockup — paste your own text in the live demo to see it run. Every mention of the same person gets the same substitute throughout the request, so a model can still follow who did what.
Pattern match
Deterministic regex takes everything with a shape — emails, API keys, tokens, phone and account numbers — and applies the rule below.
Entity recognition
A local NER model finds what has no fixed shape: people, organizations, places, project codenames, regulated ID formats.
Model audit
A model re-reads the already-redacted text hunting for whatever the first two missed. It flags what it finds; it does not quietly rewrite anything.
What “de-identified” actually means
One rule, however a detail gets caught: the real value is removed and a numbered placeholder such as <PERSON_1> takes its place — never the real value, and never a fake that could pass for a real one. The same person, company or account gets the same number throughout a request, so a model can still follow who did what. The demo below shows realistic stand-in names so it reads naturally; the stored trace uses the numbered placeholders.

Raw content is never sold. The de-identified trace is what makes the discount possible — nothing else leaves this pipeline.
Every trace is de-identified within minutes of your call completing, and the raw version is then deleted.
Your model provider still receives the prompt as you sent it, as with any direct API call — a gateway can’t change that.
Run it yourself.
The real pipeline, all three passes, on whatever you paste or upload — the same audit model the production pipeline runs, not one you pick. No login required.
A de-identified copy of what you run here may be kept to improve the product.
Three passes, run once. Nothing here is scored, flagged, or stored. Click any highlighted span to see why the pipeline treated it that way.
Start with a pilot key.
Pilot keys are self-serve — get one in minutes, no sales call. Every call through it is protected by the same 3-pass de-identification pipeline described above, so you get 90% off without worrying about what’s in your prompts.
