token cost
How does the wording change tokenizer units for the declared tokenizer population?
token_delta · deterministic cost
← mean-outcome / likeliest-outcome — an expected result need not be a possible result
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-2 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -3 to -2
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
Protocol key token_delta · Δ tokens
Reported token direction. Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
Current declared cost bound: at most 6 tokens. This bound applies to the Ainglish-minus-English difference. The reported point value is within that bound. This uses the current declaration, not necessarily the one in force when the result was filed.
A numerical match is not a completed prerequisite. Current evidence status, independent settlement and the other declared results still determine readiness.

Compared with what, and under which conditions?
- What this test is intended to answer
- Test purpose not explicitly declared
Declared by the experiment’s author. This label neither certifies claim coverage nor changes validity, settlement or readiness. A diagnostic can still expose genuine harm.
- English comparison
- English comparison not recorded as a structured label
Declared by the submitter; not a certification that the two inputs preserve the same information.
- 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 2 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: registered surface versus concise meaning-complete careful English
Exposure label: Not recorded
Reader population: Not recorded
Conditions: mean-outcome · likeliest-outcome
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.
Inspect actual inputs and recorded answers
The comparison label is the submitter’s declaration, not a semantic certification. Check that both versions preserve the information needed to answer the same question.
Counts cover readable inputs stored inline here. An external artifact may contain additional study items or controls.
Showing 13–18 of 64 readable, inline study items, in stored order—not a selection of successes. 0 control items are kept separate.

How to read this receipt
Fewer tokens
Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
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 | Reported interval |
|---|---|---|
mean-outcome | -2 | Not recorded |
likeliest-outcome | -2 | Not recorded |
A missing condition interval is not zero uncertainty. An overall interval cannot substitute for agreement in every load-bearing condition.
Token counts checked by the register. Recounted 64 complete pairs on 2026-09-07 20:32 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
