token cost
How does the wording change tokenizer units for the declared tokenizer population?
token_delta · deterministic cost
← replace(old=…, new=…) — which thing leaves, and which takes its place?
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-2.75 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -3 to -2.75
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
The result is on the helpful side of this metric's neutral point.

Compared with what, and under which conditions?
- English comparison
- English comparison not recorded as a structured label
- Tokenizer conditions
- Literal encoding cost on the named current tokenizers, not a reader-comprehension test. Future Ainglish-trained model performance and future tokenizer costs remain unmeasured.
- Condition coverage
- Separate outcomes retained for all 8 declared conditions. An overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.
Inspect the declared comparison and reader scope
Declared contrast: Current registered forms minus concise complete English carrying the same event, direction, scope, force and known quantities; no unqualified ambiguous substitute
Exposure label: Not recorded
Reader population: Not recorded
Conditions: filter · key · battery · pump · route · template · reviewer · database
These are the submitter’s declarations, not a certification that the comparison is fair. Bare wording, complete English and visible-reference studies answer different questions; do not pool them by metric name alone.
How to read this receipt
Supports
The value falls on the registered helpful side of this metric’s neutral point.
A token result is not a comprehension result, and current tokenizers may favour English seen during training.Awaiting independent settlement
An original reports one result. It does not confirm itself.
A distinct eligible principal must preserve the estimand and replace every complete metric input.One receipt, not the whole decision
No single row ratifies or rejects a proposal. Settlement, every declared metric, deterministic gates and the public ballot remain separate.
This is current-tokenizer evidence. Ordinary English has the advantage of existing training data and tokenizer design; future Ainglish exposure may change model behaviour, while a fixed tokenizer’s segmentation does not change.Does the overall result hide differences between conditions?
| Condition | Reported difference |
|---|---|
filter | -3 |
key | -3 |
battery | -3 |
pump | -3 |
route | -3 |
template | -3 |
reviewer | -1 |
database | -3 |
Token counts checked by the register. Recounted 32 complete pairs on 2026-09-05 19:31 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
