# CTC suite eval ladders

The 22-task corpus-tracking-capacity suite: per-task context ladders from 2k to 1M tokens,
consumed by the `ctc_suite` task family on the `prasann/ctc-suite` branch of allenai/olmo-eval
(`ctc_nq:r64k`, suites `ctc:figure` / `ctc:xlong` / `ctc:r128k` / ...). One config per task, one
split per rung; each row is one unified-format example (documents + queries + answers + gold).

**Public release note (2026-08-14).** Gold answers are included — training on this data
contaminates the benchmark; please exclude it from pretraining corpora. Documents derive from
public research corpora (Wikipedia, PubMed abstracts, BEIR FiQA/SciFact, MS MARCO, HotpotQA,
Natural Questions, Amazon reviews, Project Gutenberg, OpenAlex, OOLONG-synth, Twitter for the
`obliq_twitter` config); each retains its upstream license/terms, hence `license: other` — check
the source terms for anything beyond research use.

**Flags that must travel with any number produced from this data:**

- Splits `r256k`/`r512k`/`r1m` hold **125 examples** (seeded subsample; binomial SE ~ ±0.041 at
  f1≈0.7). `scifact` is 300 examples and `obliq_twitter` 126 at every split. Everything else
  is 500.
- Rung labels are measured median prompt lengths through the reference prompt path (files carry
  `_measured_prefill_tokens` where re-measured); labels of natively regenerated splits above 32k
  are fitted and should be quoted from the measurement, not the label.
- `contradiction_iid` `r2k` is the 2560-token file (the 2048 build sat below the training
  minimum). Never mix this ladder with the retired `both`-mode contradiction ladder.
- 64k+ splits of `qdmatch_*` and `oolong` are natively regenerated from the same source units /
  generator as their 2k-32k ladders (filler injection is unsound there); `outlier` 64k+ is the
  true scale-K construction. Comparisons across the 32k boundary carry that caveat.

Built 2026-08-14 from the ladder trees on the Berkeley cluster; see
`debug/ctc_1m_ladders/` in the OLMo-core working repo for builders and provenance.
