What it is

tokenpath.ai, as visitors see it

TokenPath is an API that traces AI-generated answers back to their exact sources by measuring attention directly from the model's computation. You send a document, question, and answer; the API returns which spans of the answer came from which spans of the document with confidence scores. It works with any model including GPT, Claude, Gemini, and Llama, requires no access to model weights or internals, and can run on-premise in your own VPC. TokenPath achieves frontier-grade citation quality without the frontier cost, scoring 0.815 F1 on LongBench-Cite while being approximately 7 times cheaper and 5-6 times faster than comparable solutions.

What it is built with

  • Token-level attribution with confidence scores
  • Works with any AI model without access to weights or internals
  • Processes documents up to 1 million tokens
  • Returns results in under 2 seconds for 20,000-token documents
  • On-premise and air-gapped deployment options
  • PDF support with character-level mapping
  • Supports 23+ languages including Indian languages
  • Chrome browser extension for page and PDF tracing
  • Raw token-by-token heatmaps available via API
  • No data logging or training on request content

Pricing

Pricing model: Freemium

Free tier for small requests with no API key required; 10 million free tokens to start; $1 per million tokens for pay-as-you-go, with discounts available at volume or with annual commitments; failed requests are never charged.

Questions from the bench

What exactly is the TokenPath API?
One HTTP endpoint where you send a document, question, and answer already produced by your model. You get back which spans of the answer came from which spans of the document with confidence scores. TokenPath generates nothing, rewrites no prompts, and operates after the answer exists as a pure measurement.
Does it work with my model?
Yes, all of them. Attribution runs after generation and needs only text, not access to model weights, logprobs, or internals. GPT, Claude, Gemini, Llama, custom fine-tunes, or final answers from multi-step agents all work identically by reading the attention of TokenPath's attribution model over your document and answer.
Can we run TokenPath on-premise, or in our own VPC?
Yes. Attribution runs on open-weight models on GPUs operated by TokenPath with no OpenAI, Anthropic, or Google in the path, and nothing that phones home. The entire system can run inside your network air-gapped if required, though it is not self-serve and requires discussion with sales to size properly.
What does it cost?
Small requests are free with no API key. Beyond that, $1 per million tokens pay-as-you-go, counted across document, question, and answer. This is the on-demand list price, with substantial discounts available at volume or with annual commitments. Start with 10 million free tokens and no card required.
How fast is it, and how long can the document be?
A 20,000-token document (roughly 30 pages) returns in under two seconds. Longer source text up to 1 million tokens is automatically split into overlapping model-sized windows, with a result returned only once every window succeeds.
