What

Adds GPT-6.1 Terra (gpt-6.1-terra) as two Codex evidence pipelines, and leaderboard rows for Codex GPT-6.1 Terra and Codex GPT-6.1 Sol.

Why

GPT-6.1 Terra is OpenAI's new fast, low-cost model, priced at half of GPT-6.1 Sol.

How

  • codex_code_extract_gpt_6_1_terra_low_evidence and codex_code_extract_gpt_6_1_terra_medium_evidence join the GPT-6 evidence sweep with the same config as GPT-6.1 Sol (unrestricted shell, no cost cap, page and box citations).
  • Pricing per 1M tokens: $1.00 input, $0.05 cached input, $1.25 cache write, $5.00 output.
  • Both leaderboard rows are the low-effort pipelines (codex_code_extract_gpt_6_1_terra_low_evidence, codex_code_extract_gpt_6_1_sol_low_evidence) over all 370 documents (252 short / 98 medium / 20 long). The GPT-6.1 Sol pipelines were already registered.

Results

Row Overall Short Medium Long Word grounding Page grounding ¢/page
Codex (GPT-6.1 Sol Evidence) 95.31 97.01 92.96 85.46 87.61 89.37 7.13
Codex (GPT-6.1 Terra Evidence) 94.28 96.26 91.86 81.21 85.69 87.42 4.68
Codex (GPT-6 Sol Evidence), existing 94.57 95.99 92.42 87.25 77.11 86.50 9.80

GPT-6.1 Sol and Terra take the top two word-grounding scores on the leaderboard.

Changes

  • src/extract_bench/inference/pipelines/extract.py: Terra entry in the GPT-6 evidence sweep
  • src/extract_bench/inference/providers/extract/codex_code_extract.py: pricing rows
  • docs/pipelines.md: Terra pipelines
  • leaderboard.csv: two rows
  • README.md: regenerated by scripts/update_readme.py

Testing

  • extract-bench pipelines lists both pipelines
  • ruff check on the changed source files passes
  • scripts/update_readme.py changes only the two generated tables

Notes

Requires the Codex CLI and OPENAI_API_KEY. These pipelines run local shell commands; see the README warning.

Register codex_code_extract_gpt_6_1_terra_{low,medium}_evidence in the
GPT-6 evidence sweep, price gpt-6.1-terra at $1.00 input, $0.05 cached
input, $1.25 cache write and $5.00 output per 1M tokens, and add the
low-effort run to the leaderboard.
Low-effort evidence run over all 370 documents.
