For teams

Buying seats for Claude Code, Codex, or Grok Build? Here is steady, dated data you can check yourself before you sign.

The three questions buyers ask

A buyer’s check, in order

Twenty minutes across these five pages will tell you more than a vendor deck.

  1. Compare the two you are choosing between

    Same 24-hour window, same unit, side by side. Rank on wall tok/s, and glance at clean runs — a number from 3 rounds can swing, one from 90 barely moves.

  2. Open the page for the model you would actually use

    One page per pin: write speed, time to first word, clean rounds, rate limits, and how it moved since yesterday. A team seat runs one model, not an average of four.

  3. Check this week, not just the average

    Logins, rate limits, and the exact app versions behind today’s numbers. We measure on a fixed clock, so a vendor change shows up the day it ships.

  4. Open the samples behind the summary

    Every run we saved, every fail with a label, and the tokens our lab spent. If a board looks too good, this is where you go to doubt it.

  5. Read the fine print before you quote it

    Exact prompts, exact flags, pinned models, and the test kit version — boards only show the current kit, v6. Do not put a number in a deck before you read this page.

How to read this

Every figure on this site is one we measured ourselves on our own machine. None of it is an official vendor benchmark. Read How we test before you quote a number in a buying decision.

What we never do

The longer story is on About.

Honest limits

Read these before you put a figure in a business case.

One machine, one network
Every number comes from one dedicated lab machine on a normal home connection, using the app versions listed on Status. Your office setup will not match ours exactly.
Short jobs only
We time a tiny ping and a 1-to-120 count. We do not yet measure long agent work in a real repository.
No pricing model
We publish the tokens our lab spent, not what a seat will cost your team. Plan pricing is the vendor’s page, not ours.
Not a contract number
These are our measurements, not official vendor numbers, and no vendor promises them. Use them to compare tools and spot a bad week. Do not paste one into a contract or an SLA.

Talk to us

Use the contact link in the footer if you need a model we do not track yet, or want a number checked before a big buy. A person answers, and we will tell you plainly if the data cannot support the question. The raw numbers are on the Developers page as JSON feeds — no key, no account.
