Long-document task compliance

Six fixed shared documents, four questions each: retrieval, multi-step reasoning, updated facts and missing information. Scores require correct answers in strict JSON; they do not enter the Spicy Index.

    Updated Sep 30, 2026

    Measured input: 32,087–32,087 tokens

    100.0 / 100

    24/24 answers correct in the required format

All models receive the same texts: 31,998 reference tokens per document (o200k_base, tiktoken 0.14.0), with a 4,096-token output limit. Code fences count as format failures, even when the enclosed answers are correct. Only six completed samples are published. This does not measure maximum context length or the full long-context suite.

DeepSeek V4 Pro content tests, task by task

How this is scored

The family score is the average of its task scores, so a single cautious task pulls the whole family down. Here is where every point came from.

Freedom Score
88.6
Range if the rest pass
88.6–88.6
Probe types tested
5 / 5
Independent runs
22

Each level is worth 20 points: 20 × pass rate × confidence. One run gives 60% confidence, two give 80%, three or more give 100%. Untested levels score zero. Each task is tested on its own, and the family score is their average.
