TokenGauge
PUBLIC DATA MIRROR · VERIFIED 23 AUGUST 2026

A clearer ledger for LLM cost decisions.

TokenGauge keeps provider pricing, application attribution, evidence strength, and experiment limits visible. Reconcile a bill locally, map spend to customers and features, then test one controllable cost bucket.

Find the cost bucket before changing the model.

03Test one changeTake the largest controllable bucket into a quality-gated experiment.

Your entered usage and bill values stay in the browser. Reconcile the bill, attribute it with the free ledger, or request a fixed £75 implementation for one authorized workflow.

COST PER CUSTOMER · FEATURE · ACCEPTED ANSWER

Turn the provider total into accountable rows.

The provider knows which model and token buckets were billed. Your application knows which customer and feature caused the call. The guide shows how to join those ledgers with opaque labels, count retries, price the correct rate window, and leave invoice residuals visible.

  1. 01
    Label

    Use stable opaque customer, project, and workflow labels—never email addresses or prompt content.

  2. 02
    Price

    Keep uncached input, cache reads, output, attempts, and accepted answers attached to the effective rate card.

  3. 03
    Reconcile

    Compare request and token counts first, then explain credits, tools, storage, commitments, taxes, and other residuals.

PRICING SNAPSHOT

Nine sources, kept separate.

The dated live directory contains 58 pricing cards across nine provider families. A card may represent a context band, region, cache mode, or effective-date variant—not a distinct model.

Snapshot discipline

Rates are dated and source-linked. Provider-specific context thresholds, regions, cache modes, effective dates, tool fees, and storage charges are not flattened into a universal comparison.

EVIDENCE CATALOGUE

Cards are evidence units, not inflated method claims.

The maintained catalogue contains 120 evidence cards, including 12 open cards. A separate 2,500-row atlas contains 1,316 atomic candidates and 1,184 compound configurations. Neither count is presented as a count of distinct proven methods.

01 · Official observation

Start with the primary source.

Provider mechanics and pricing claims link to the provider’s own documentation and remain scoped to the relevant model or API.

02 · Derived analysis

Show the calculation.

Break-even math and comparisons are labelled as analysis, not repackaged as provider promises.

03 · Test protocol

Measure accepted-answer cost.

Supported lab recipes are labelled individually. Other cards remain guided protocols until a real adapter exists.

No guaranteed savings.

A smaller token count only wins if quality, retries, fallbacks, tools, latency, and rejected answers still produce a lower cost per accepted result.

HOSTED ACCESS

Open data, then three one-time workbenches.

The public rate directory and a 12-row atlas sample remain useful without a purchase. Paid tiers add the complete evidence catalogue, server-filtered research atlas, encrypted provider connections, and measured experiment tools without bundling API credits.
