Evans Law Context & Coherence Testing Kit

This kit provides standardized materials in docx format for testing context retention, coherence degradation, and scaling effects across large-language models using the Evans Law framework. Each section can be used independently or sequentially to evaluate model performance at different context lengths.

Section 1 — Instructions and Parts A and B

Read the test overview and follow the setup instructions before beginning any runs. This section also contains text copy for 4K and 10k token tests.

Download Instructions + Parts A & B (DOCX)

Section 2 — Part C
Part C extends the test to full-context (≈ 30 k tokens) conditions. Use this only after the model has completed Parts A and B without truncation or coherence loss.

Section 3 — How to Use the Kit, Submitting Results & Reporting Coherence Tests

Researchers, model developers, and independent testers are invited to contribute their results to help refine Evans’ Law data.

How to Participate:

  1. Run the tests — complete Parts A through C in order, using the instructions provided above.
  2. Record the model details: (as much as you can)
    • Model name and version (e.g., GPT-5, Claude 3.5 Sonnet, Gemini 2 Ultra)
    • Context length used (tokens)
    • Observed coherence level (Low / Medium / High or numeric score)
    • Any truncation or factual drift
  3. Share your data:
    • Upload your summarized results as a CSV, PDF, or Markdown file.
    • Include a one-paragraph description of test conditions (temperature, sampling, etc.).
  4. Submit via:
