GLM 5.3: price, limits and messages on every plan

Short answer
GLM 5.3 is in llmwise's one-time free trial of 5 messages. A paid plan gives up to 250 GLM 5.3 messages a month on Pro ($20), 800 on Max ($50), 1,800 on Ultra ($100) and 4,000 on Studio ($200). Each GLM 5.3 message's price is shown before you send it.
GLM 5.3 on every plan
What GLM 5.3 costs in llmwise is a count, not a token bill: up to 250 a month on Pro, and it's one of the models in the 5-message free trial.
| Plan | Price | GLM 5.3 messages | Each, if all go to GLM 5.3 |
|---|---|---|---|
| Free | $0 | In the one-time trial of 5 messages | — |
| Pro | $20 a month | Up to 250 a month | $0.08 |
| Max | $50 a month | Up to 800 a month | $0.06 |
| Ultra | $100 a month | Up to 1,800 a month | $0.06 |
| Studio | $200 a month | Up to 4,000 a month | $0.05 |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance every model shares, so each GLM 5.3 count is the most you get if all of it goes to GLM 5.3, and "each" is the plan's price divided by that count. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
GLM 5.3 usage limits, explained
Every limit on GLM 5.3 in llmwise is published. Here's each one, in GLM 5.3 messages.
GLM 5.3 draws on the monthly allowance every model shares: 250 GLM 5.3 messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer GLM 5.3 messages, each GLM 5.3 message leaves fewer for them, and unused GLM 5.3 messages don't carry over when the billing period renews.
Long GLM 5.3 chats count more, because each GLM 5.3 reply resends the whole conversation. Past 64k tokens a GLM 5.3 reply counts as 2 messages, so Pro's 250 GLM 5.3 messages become up to 125 such replies; past 128k it counts as 4 (up to 62 GLM 5.3 replies); past 200k the GLM 5.3 chat is full.
GLM 5.3's native context window is 1.05M tokens; llmwise stops a GLM 5.3 chat at 200k tokens, so a GLM 5.3 chat uses at most 200k of its 1.05M tokens.
A GLM 5.3 reply can run to 8,000 tokens on Pro and 16,000 on Max, Ultra, and Studio, at the same GLM 5.3 price however long it runs.
On a paid plan each web search or link read in a GLM 5.3 reply counts as 1 more GLM 5.3 message.
A $10 top-up adds up to 200 more GLM 5.3 messages, valid 12 months, spent once the plan's own GLM 5.3 count is gone.
GLM 5.3 replies share every plan's soft cap of 100 replies an hour with the other models.

Where your GLM 5.3 messages go
llmwise doesn't call Z.ai for GLM 5.3: every GLM 5.3 message goes through OpenRouter, which routes it to a company hosting GLM 5.3.
Each GLM 5.3 request asks OpenRouter only for GLM 5.3 hosts that, according to OpenRouter, don't store prompts for their own use or train on them, and skips any listed as running a 4-bit (fp4) build of GLM 5.3. The GLM 5.3 host that answers can be a hosting company rather than Z.ai, under its own terms.
If one GLM 5.3 host is down, OpenRouter moves the GLM 5.3 request to another that meets the same terms.
The Privacy Policy lists every company a GLM 5.3 message can reach.
GLM 5.3's API price, and what a message costs
GLM 5.3's API price is $1.40 per million tokens in and $4.40 out: Z.ai's list price. At that price a typical GLM 5.3 message (4,000 tokens in, 700 out) costs about $0.0087.
In llmwise a GLM 5.3 message isn't billed by the token: it's one of up to 250 GLM 5.3 messages a month on Pro, however long the GLM 5.3 reply runs.
When to use GLM 5.3, and when a cheaper model will do
llmwise's catalog describes GLM 5.3 as “Z.ai's capable open-weight model”. No benchmark scores here: ask GLM 5.3 your own question, then switch the picker to another model in the same chat, which sees GLM 5.3's answer too.
When a question doesn't need GLM 5.3, these read the same attachments and leave more of the month for GLM 5.3:
GLM 5.3 Flash (Z.ai): 60 a day on Pro, against GLM 5.3's 250.
GPT-6 Luna (OpenAI): 60 a day on Pro, against GLM 5.3's 250.
