Updated the multimodal_doc_parser_compare_n171_report.md to include detailed code citations for preprocessing costs and retry logic. Improved clarity on the implementation of the retry mechanism and its impact on failure rates. Added a new section for a code citations index to ensure reproducibility of technical claims.
This enhances the report's transparency and allows readers to trace the source of each claim back to the codebase.
Adds the full parser_compare experiment for the multimodal_doc suite:
six arms compared on 30 PDFs / 171 questions from MMLongBench-Doc with
anthropic/claude-sonnet-4.5 across the board.
Source code:
- core/parsers/{azure_di,llamacloud,pdf_pages}.py: direct parser SDK
callers (Azure Document Intelligence prebuilt-read/layout, LlamaParse
parse_page_with_llm/parse_page_with_agent) used by the LC arms,
bypassing the SurfSense backend so each (basic/premium) extraction
is a clean A/B independent of backend ETL routing.
- suites/multimodal_doc/parser_compare/{ingest,runner,prompt}.py:
six-arm benchmark (native_pdf, azure_basic_lc, azure_premium_lc,
llamacloud_basic_lc, llamacloud_premium_lc, surfsense_agentic) with
byte-identical prompts per question, deterministic grader, Wilson
CIs, and the per-page preprocessing tariff cost overlay.
Reproducibility:
- pyproject.toml + uv.lock pin pypdf, azure-ai-documentintelligence,
llama-cloud-services as new deps.
- .env.example documents the AZURE_DI_* and LLAMA_CLOUD_API_KEY env
vars now required for parser_compare.
- 12 analysis scripts under scripts/: retry pass with exponential
backoff, post-retry accuracy merge, McNemar / latency / per-PDF
stats, context-overflow hypothesis test, etc. Each produces one
number cited by the blog report.
Citation surface:
- reports/blog/multimodal_doc_parser_compare_n171_report.md: 1219-line
technical writeup (16 sections) covering headline accuracy, per-format
accuracy, McNemar pairwise significance, latency / token / per-PDF
distributions, error analysis, retry experiment, post-retry final
accuracy, cost amortization model with closed-form derivation, threats
to validity, and reproducibility appendix.
- data/multimodal_doc/runs/2026-05-14T00-53-19Z/parser_compare/{raw,
raw_retries,raw_post_retry}.jsonl + run_artifact.json + retry summary
whitelisted via data/.gitignore as the verifiable numbers source.
Gitignore:
- ignore logs_*.txt + retry_run.log; structured artifacts cover the
citation surface, debug logs are noise.
- data/.gitignore default-ignores everything, whitelists the n=171 run
artifacts only (parser manifest left ignored to avoid leaking local
Windows usernames in absolute paths; manifest is fully regenerable
via 'ingest multimodal_doc parser_compare').
- reports/.gitignore now whitelists hand-curated reports/blog/.
Also retires the abandoned CRAG Task 3 implementation (download script,
streaming Task 3 ingest, CragTask3Benchmark + tests) and trims the
runner / ingest module APIs to match.
