Data

One file holds every trial. Here it is, and what each column means.

trials.csv 2,640 rows · 60 columns · 1.3 MB

trials.csv has one row for every counted trial: 2,640 rows, which is the 2,608 trials of the campaign plus the 32 trials of the pilot. It follows RFC 4180: comma-separated, fields quoted when they hold a comma, quote or line break, and booleans written as true and false. An empty cell means the value does not apply to that row or was not recorded, such as a feature flag on a pick-a-number trial or the turn count of a pilot trial.

The file is generated and never edited by hand. The tally script in the repo, bin/tally.mjs, reads runs/<run>/trials.jsonl and the output files each trial left behind, computes the features and the answers, and writes the CSV. The columns are frozen: a new one is added at the end, never renamed or reordered. This site refuses to build if the header and the glossary below disagree.

Columns

column meaning
Identity 11
run Run name: task, mode, model and effort, e.g. circle-sample-claude-haiku-4-5-20251001-low. pilot-import holds the 32 pilot trials.
task What the model was given: circle, html, svg, replica, sentence, number, digit or word.
mode sample (independent trials from the same seed), chain (each step starts from the previous step’s output) or pilot (the original 32-trial pilot).
profile room (stripped Claude Code: four tools, no user config) or harness (the everyday Claude Code setup with the full user config).
step Trial number within the run, from 1. In a chain it is also the position in the chain.
model Model id the CLI reports as having answered. In relay runs it rotates by step.
model_asked Model id or alias passed to the CLI. Differs from model only for the pilot and harness replica, which asked for the alias haiku.
effort Reasoning effort setting. low on every row.
cli_version Claude Code CLI version that ran the trial.
session_id Session UUID of the trial.
started_utc When the trial started, UTC, ISO 8601.
Cost and behavior 9
wall_s Wall-clock seconds for the trial.
cost_usd Cost in US dollars as the CLI reported it (API-equivalent value, not a bill).
turns Number of model turns in the session. Empty for the pilot.
output_tokens Output tokens the model generated, thinking included. Empty for the pilot.
thinking_blocks Count of thinking blocks in the session. Empty for the pilot.
denials Tool calls the permission system refused, such as a Bash command in the stripped room. Empty for the pilot.
tool_calls Total tool calls the model made.
bash_calls Bash tool calls (allowed or denied).
edit_calls Edit plus Write tool calls.
Lineage 5
input_sha256 SHA-256 of the room the trial started with. For a chain step after the first, the previous step’s output.
output_sha256 SHA-256 of the room after the trial.
from_seed True when the input room is byte-identical to the task’s seed. Empty for text tasks, which have no seed file.
unchanged True when input and output hashes match: the model left the room exactly as it found it. Empty for text tasks, which have no file.
same_picture True when the trial’s render is pixel-identical to the render of its input (the seed, or the previous chain step), whether or not the file changed. Empty for tasks without a render (the text tasks and sentence).
The output file 4
file Name of the file the model was asked to improve: 0.html, 0.svg, 0.txt or f7b3.html. Empty for text tasks that answer in chat.
bytes Size of the output file in bytes.
lines Lines of text in the output file. A final newline does not add a line: this is wc -l, plus one when the last line has no newline, and 0 for an empty file.
extra_files Files in the room besides the output file, such as scratch files the model created.
Features of the output 12
glow_or_shadow Output matches box-shadow, drop-shadow, text-shadow, feGaussianBlur, feDropShadow or glow (case-insensitive).
glow Output contains the word glow.
keyframes Output contains @keyframes.
radial_gradient Output uses radial-gradient (CSS) or radialGradient (SVG).
linear_gradient Output uses linear-gradient (CSS) or linearGradient (SVG).
pulse Output contains the word pulse.
gradient_667eea Output contains both #667eea and #764ba2, the purple gradient pair.
script Output contains a <script> tag.
nondeterministic Output calls Math.random or the clock: it contains Math.random, Date.now, new Date, performance.now or getRandomValues. The flag says nothing about whether the render varies.
svg_filter Output contains an SVG <filter> element.
hex_count Number of distinct hex colors in the output.
hex_colors The distinct hex colors, space-separated, lowercase #rrggbb (shorthand expanded, alpha dropped), in order of first appearance.
Text answers 7
answer_raw The model’s answer verbatim: its final message for number, digit and word; the trimmed sentence file for sentence.
answer_value The answer normalized: a bare number, a lowercase word, or for sentence the sentence itself. Empty when nothing could be extracted.
answer_form bare when the reply was just the value, framed when it was wrapped in prose, none when no value was found.
answer_ok Whether the answer met the task’s rule: any number for number, a single digit for digit, a word for word, exactly one word added and none removed for sentence. False when no value was found.
words Word count of the sentence after the trial (sentence task only).
added Words added compared with the previous sentence, space-separated (sentence task only).
removed Words removed compared with the previous sentence, space-separated (sentence task only).
The self-report 2
result_chars Length in characters of the model’s final message.
mentions_server The final message contains server as a whole word (case-insensitive). In the pilot, usually an offer or request to start one.
Spelling 10
color_p_uk British (-our) forms of the word color and its inflections in the model’s prose: its text messages across the session, code excluded. For the pilot and harness replica, which have no transcript, the final message only.
color_p_us American forms of color (color, colored, ...) in the model’s prose, as for color_p_uk.
center_p_uk British (-re) forms of the word center and its inflections in prose, as for color_p_uk.
center_p_us American forms of center (center, centered, ...) in prose, as for color_p_uk.
gray_p_uk British (-ey) forms of the word gray and its inflections in prose, as for color_p_uk.
gray_p_us American forms of gray (gray, grayed, grayish) in prose, as for color_p_uk.
ize_p_uk British -ise forms of common design verbs (the counterparts of optimize, emphasize, organize and the like) in prose, as for color_p_uk.
ize_p_us -ize forms of the same verbs (optimize, emphasize, organize, ...) in prose, as for color_p_uk.
spell_c_uk British forms across all four families inside the model’s tool inputs (file contents, edits, commands). Empty when the trial has no transcript.
spell_c_us American forms across all four families inside the model’s tool inputs. Empty when the trial has no transcript.
