They were + measured on `wraithfast-phase14-100k-full-ft` + `wraithfast-phase15-150k-qlora`, a text-only + checkpoint predating the vision composition that contains none of the Piko training stages. + They have been removed and replaced with measurements taken on the published weights. +* **"Coding 100% / OCR 75% / Overall 83.3%."** These came from a 4-item-per-section keyword test + run against `adapters/piko9-phase5-ocr-normal-70k-qlora`, an adapter not present in the + published weights. Removed. +* **Training narrative.** The card described six training stages totalling 520,000 examples, each + merged before the next began. Tensor comparison shows **none** of those stages are present in + the published weights, and the training configs show all five text stages share one base + checkpoint rather than forming a cumulative chain. +* **"Stage 6: 150,000 — Images, using the built-in vision encoder."** No vision training took + place. The phase-6 log records only: download vision checkpoint → compose → run smoke benchmark + → crash (TLS failure fetching `images.cocodataset.org`).

It is **not** a substitute +for standard benchmarks — it is 70 hand-written cases whose grading you can read in a few minutes. + +## Design decisions + +**No judge model.** Every case is graded by a deterministic Python check in +[`run_custom_eval.py`](run_custom_eval.py). Nothing is scored by another LLM, so results are +reproducible and carry no grader bias. The cost of that choice is real: a correct answer phrased +unexpectedly can be marked wrong. Read `reason` in the output JSON before trusting a failure. + +**Synthetic, self-generated fixtures.** Every image is drawn from code by +[`build_assets.py`](build_assets.py). Nothing is downloaded, so the suite has no dataset licence, +no privacy exposure, and no network dependency — and it cannot silently break when a remote host +changes its TLS certificate, which is exactly how the original project's vision benchmark died. + +**Reasoning traces are stripped before grading.** The model emits a `…` span. Only +the text after `` is graded, so a case is judged on its visible answer. + +## Contents + +| File | Cases | What it checks | Grading | +|---|---:|---|---| +| `cases/instruction_following.jsonl` | 10 | Exact formats: line counts, bullet counts, word caps, JSON keys, forbidden letters | Structural | +| `cases/reasoning.jsonl` | 10 | Arithmetic, dates, syllogisms, probability | Numeric / substring | +| `cases/ocr.jsonl` | 10 | Reading printed text off rendered documents, including a deliberately mangled scan | Substring | +| `cases/document_understanding.jsonl` | 10 | Fields, arithmetic across fields, date spans, structured extraction | Substring / JSON | +| `cases/tables_charts.jsonl` | 10 | 5 table questions, 5 chart questions, including cross-row totals | Numeric / JSON | +| `cases/coding.jsonl` | 5 | Generated functions are **executed** against assertions in a subprocess | Execution | +| `cases/hallucination_safety.jsonl` | 10 | 5 invented entities that must be refused; 5 harmful/jailbreak prompts | Marker search | +| `cases/long_context.jsonl` | 5 | Needle-in-a-haystack at 2K / 8K / 32K filler tokens, depths 0.1–0.9 | Substring | + +**Total: 70 cases.** 30 of them require image input. + +Measured on the published Piko-9b weights (4-bit NF4, greedy, RTX 5070 Ti, 2026-07-29): **65/70**. +`Qwen/Qwen3.5-9B` run identically: **63/70**.

A model that refuses politely in an unlisted phrasing +scores a false failure; one that says "I cannot verify that" and then hallucinates anyway scores a +false pass. Treat those two categories as smoke tests, and read the responses. + +`python_exec` runs model-generated code in a subprocess with a timeout. It is **not** a security +sandbox. Only run it against models and prompts you control. + +## Output + +A JSON file recording, for every case: pass/fail, the grading reason, wall time, the prompt, and +the model's response (truncated at 4,000 characters). The header records model, revision label, +Python / torch / transformers versions, GPU, dtype, quantization, decoding parameters, seed, and +batch size, so a result can be compared against another run honestly. diff --git a/evaluation/custom_suite/assets/bar_chart.png b/evaluation/custom_suite/assets/bar_chart.png new file mode 100644 index 0000000000000000000000000000000000000000..8799a629ef90f6aecd9f49d2698fb9dba23d3234 Binary files /dev/null and b/evaluation/custom_suite/assets/bar_chart.png differ diff --git a/evaluation/custom_suite/assets/form.png b/evaluation/custom_suite/assets/form.png new file mode 100644 index 0000000000000000000000000000000000000000..de8065b63c07faae5f7c8739c22af1e907520241 Binary files /dev/null and b/evaluation/custom_suite/assets/form.png differ diff --git a/evaluation/custom_suite/assets/invoice.png b/evaluation/custom_suite/assets/invoice.png new file mode 100644 index 0000000000000000000000000000000000000000..5b3d4b001fa92b89d9b6ec5e2a648caa83b2180d Binary files /dev/null and b/evaluation/custom_suite/assets/invoice.png differ diff --git a/evaluation/custom_suite/assets/line_chart.png b/evaluation/custom_suite/assets/line_chart.png new file mode 100644 index 0000000000000000000000000000000000000000..f5d2bab7599a2eb08c6d8ad31160a7b9cbd32935 Binary files /dev/null and b/evaluation/custom_suite/assets/line_chart.png differ diff --git a/evaluation/custom_suite/assets/noisy_scan.png b/evaluation/custom_suite/assets/noisy_scan.png new file mode 100644 index 0000000000000000000000000000000000000000..fa521fa4cae95f423d15032a0d1177fb646d6025 Binary files /dev/null and b/evaluation/custom_suite/assets/noisy_scan.png differ diff --git a/evaluation/custom_suite/assets/receipt.png b/evaluation/custom_suite/assets/receipt.png new file mode 100644 index 0000000000000000000000000000000000000000..31cf497f251603b8c1d84166efd4cac51edaa1d2 Binary files /dev/null and b/evaluation/custom_suite/assets/receipt.png differ diff --git a/evaluation/custom_suite/assets/table.png b/evaluation/custom_suite/assets/table.png new file mode 100644 index 0000000000000000000000000000000000000000..1af70fd802de3aea5caafeeb4729a4d2967a99b7 Binary files /dev/null and b/evaluation/custom_suite/assets/table.png differ diff --git a/evaluation/custom_suite/build_assets.py b/evaluation/custom_suite/build_assets.py new file mode 100644 index 0000000000000000000000000000000000000000..92b6c369ba08f8bfb9b6b607036ca9cc3b9488ef --- /dev/null +++ b/evaluation/custom_suite/build_assets.py @@ -0,0 +1,166 @@ +#!/usr/bin/env python3 +"""Render the synthetic images used by the visual half of the custom suite. + +Everything is drawn from code, so the fixtures are deterministic, redistributable, +and free of licensing or privacy questions.
