Every figure is quoted from the vendor's official page, with the date we read it. If a row is missing, the source does not state it and we do not estimate it.

What it means and the source

How many real programming problems (issues of open source projects) it solves on its own in the independent SWE-bench Verified ranking. The higher, the better it writes and fixes code.

Memory and answer length

Context window
200k tokensRank 20 of 21
What it means and the source

How much text the model keeps in view in a single request, question and answer included. It matters for long documents and whole code projects. A token is a fragment of a word.

128k tokensRank 3 of 16
What it means and the source

The longest answer it can write in one go: useful for reports, long code or translations of whole documents.

API prices

Input cost per 1M tokens
$0.60Rank 4 of 21
What it means and the source

What it costs to have the model read a million tokens (your question, the documents, the code). It is the official list price, before discounts.

Cached input cost per 1M tokens
$0.11Rank 10 of 20
What it means and the source

The reduced price when part of the request is identical to one sent recently, for example the same instructions or the same document: the vendor keeps it in memory and charges less for it.

Output cost per 1M tokens
$2.20Rank 4 of 21
What it means and the source

What a million tokens written by the model cost. It usually costs more than the input and is the figure to watch when answers are long.

What it means and the source

The size of the network: how many billions of learned values make it up. Bigger does not necessarily mean better, but it tells how much hardware it takes to run it yourself.

Yes7 models out of 23
What it means and the source

The model's weights can be downloaded: you can run it on your own servers, adapt it and decide where the data stays, within the licence terms.

Hardware to try AI at home

GLM-4.6: just holding the weights in memory takes about 714 GB at 16-bit, 357 GB at 8-bit, 178.5 GB at 4-bit. Beyond 24 GB it is not a home-PC job: using it through an API makes more sense.Worked out from the billions of parameters the vendor states, not a measurement: context and the runtime need more memory.

Questions and answers

GLM-4.6: how much does it cost through the API?

The official list price is $0.60 per 1M input tokens and $2.20 per 1M output tokens.

GLM-4.6: how much text can it read at once?

The context window is 200k tokens. It can write answers of up to 128k tokens.

GLM-4.6: can I run it on my own computer?

Yes, the vendor publishes the model's weights. Parameters: 357 billion. Holding them in memory takes about 178.5 GB at 4-bit; context and the runtime need more memory.

GLM-4.6: how good is it at coding?

It solves 68.2% of the problems in SWE-bench Verified, the independent ranking of real programming problems.
