We send exactly the same task prompt and the same materials to the 4 AIs on the same day. We open a new chat every time so earlier answers don't carry over. The sending order is rotated in each run. We also record the seconds from sending until the answer stops.

Why do you send the same task 3 times?

Because AI answers vary even for the same question. From a single try, you can't tell whether a result reflects real ability or chance. We send each task 3 times, and the share of tasks whose conclusion matched is reported as the consistency rate.

Who does the scoring?

Scoring is done only by a program. We do not let AI score the answers. The correct answers are set when the tasks are created, and whether an answer is right is decided by whether numbers match, whether required words are present, whether the format fits, whether URLs actually open and the result of running formulas. Matters of taste are not scored.

Is the data in the tasks from real companies?

No. We create new data for a fictional company every time. We do not use real companies, real people or text from other companies. We share the materials we used as they are, so you can repeat the same test.

How do you count cases where the AI couldn't answer?

Refusals and timeouts stay in the base and are counted as wrong. If we hit the plan's usage limit or a human verification screen appears, we remove that trial from the base and treat it as not measured. Operating errors on AInformation's side are also removed from the base, and we do not report them as the AI's fault.

Do you use the free or paid versions?

We use each AI's paid plan through the browser interface. We don't use the API. For each run, we record the plan name, the model name shown on screen and the time we checked it.

Does this ranking show which AI is the smartest?

No. We measure only 5 things on a fixed set of work tasks: accuracy, time to answer, consistency rate, real-source rate and instruction compliance. We do not measure writing style, readability or behavior in long conversations. If the tasks change, the ranking changes too.

SCORES

Scores by AI

Sorted by accuracy, highest first. The base is the number of trials in which that metric could be measured. “—” means not measured; it does not mean 0%.

Reading numbers from images of receipts, charts, and tables (4 AIs, 6 tasks, 3 runs each): scores by AI
AI	AccuracyCorrect ÷ valid trials	ConsistencySame conclusion in all 3 trials	Real-source rateShare of URLs that opened	Instruction complianceMet length and format rules	Time to answerMedian / range

4Claude	55.6% 10 of 18 trials	88.9% out of 6 tasks	—	16.7%	13.9 s 13.8–20.1 seconds

The real-source rate is measured only in runs that included a task asking for URLs along with the answer. For ChatGPT, Gemini, Copilot and Claude, “—” means this run did not include that kind of task. It does not mean 0%.

Trials with no answer
ChatGPT … Timed out: 1 time · Gemini … Timed out: 3 times · Copilot … Timed out: 1 time
Refusals and timeouts stay in the base and count as incorrect. Plan limits, human verification screens and operating errors on AInformation's side are excluded from the base.

MATERIALS

Materials used in the tasks

Original images we created ourselves: a receipt photo, a bar chart image, and a slightly tilted table image. The original numbers were set when we created them We recreated them for this run on October 23, 2026. Download them to repeat the same test yourself.

METHOD

How we measure

We list this run's conditions exactly as they were, so anyone can repeat it.

AIs measured and their model names at the time

AI services change under the hood without notice. We record the model name shown on screen and the time we checked it.

AIs measured and model names
AI	Plan	Model name shown on screen	Time checked
ChatGPT	ChatGPT Pro	GPT-6.1 Sol Light	2026-10-23 20:56
Gemini	Google AI Pro	Flash	2026-10-23 20:56
Claude	Claude Max	Opus 4.8 high	2026-10-23 20:56
Copilot	Microsoft 365 Personal		2026-10-23 20:56

What we did in this run

We recreated the materials for the tasks specifically for this run. The data are for a fictional company and include no real companies or people.
We created 6 tasks and set the answer keys at that point.
We sent the same prompt and the same materials to ChatGPT, Gemini, Claude and Copilot.
We sent each task 3 times, in a new chat each time.
We rotated the sending order from run to run. This keeps the time of day from skewing the ranking.
We waited up to 300 seconds for each answer, and recorded anything longer as a timeout.
Scoring: Machine scoring only (not graded by AI).
We sent 72 trials in total, and 72 of them were valid.

How we count trials with no answer

Refused or timed out
We keep it in the base and count it as wrong. Because at work, that is the same as getting no answer.
Hit the plan's usage limit
We remove it from the base. We treat that trial as not measured.
A human verification screen appeared
We stop there. We neither click through it automatically nor try to get around it.
Operating error on AInformation's side
We remove it from the base. We do not report it as the AI's fault.

LIMITS

Limits of this benchmark

So that no one judges by the numbers alone, we list what we could not measure.

This is a single run on a single day. Rankings can change with the day or the task
The plan used is each AI's paid tier (ChatGPT Pro / Google AI Pro / Claude Max / Microsoft 365 Personal). These are not results from the free tier
Measurements use only the default model and default mode (features such as Deep Research are not used)
The tasks use original data for the fictional company Sample Shoji Co., Ltd. These are not results using data from a real company
Only tasks that can be scored by machine are covered. Writing quality and readability are not measured
Measurements are taken from the same screen a person would use in a browser. These are not results from the API
For any AI whose on-screen model name could not be read in a given run, that field is left blank (null). When the name could be read, it is shown as is

DATA

Published data

In the CSV, 1 row is 1 trial. The figures on this page match a recount of that CSV. The license is CC BY 4.0.

Latest version (CSV) (Japanese) 1 row = 1 trial, 16KB
Latest version (JSON) 38KB
v1 (version at publication) (CSV) (Japanese) 1 row = 1 trial, 16KB
v1 (version at publication) (JSON) 38KB

The cumulative rankings are at /en/data/research/bench/leaderboard.json. We do not delete versions (such as v1). That way, links from people who cited them keep working.

FAQ

How do you measure?: We send exactly the same task prompt and the same materials to the 4 AIs on the same day. We open a new chat every time so earlier answers don't carry over. The sending order is rotated in each run. We also record the seconds from sending until the answer stops.
Why do you send the same task 3 times?: Because AI answers vary even for the same question. From a single try, you can't tell whether a result reflects real ability or chance. We send each task 3 times, and the share of tasks whose conclusion matched is reported as the consistency rate.
Who does the scoring?: Scoring is done only by a program. We do not let AI score the answers. The correct answers are set when the tasks are created, and whether an answer is right is decided by whether numbers match, whether required words are present, whether the format fits, whether URLs actually open and the result of running formulas. Matters of taste are not scored.
Is the data in the tasks from real companies?: No. We create new data for a fictional company every time. We do not use real companies, real people or text from other companies. We share the materials we used as they are, so you can repeat the same test.
How do you count cases where the AI couldn't answer?: Refusals and timeouts stay in the base and are counted as wrong. If we hit the plan's usage limit or a human verification screen appears, we remove that trial from the base and treat it as not measured. Operating errors on AInformation's side are also removed from the base, and we do not report them as the AI's fault.
Do you use the free or paid versions?: We use each AI's paid plan through the browser interface. We don't use the API. For each run, we record the plan name, the model name shown on screen and the time we checked it.
Does this ranking show which AI is the smartest?: No. We measure only 5 things on a fixed set of work tasks: accuracy, time to answer, consistency rate, real-source rate and instruction compliance. We do not measure writing style, readability or behavior in long conversations. If the tasks change, the ranking changes too.
Can I cite these results?: Yes. The license is CC BY 4.0. As the source, please write “Source: AInformation, AI Practical Work Benchmark” with the URL of the page you used and the measurement date. The results are also available as JSON and CSV. With the CSV (1 row per trial), you can recount the figures we publish.
