GLM 5.3 Flash: price, limits and messages on every plan
Z.ai's GLM 5.3 Flash in llmwise: how many GLM 5.3 Flash messages each plan gives, what counts against them, what GLM 5.3 Flash reads, where your messages go, and what it costs at Z.ai's API prices.
Prices and limits checked against OpenRouter's GLM 5.3 Flash page. Updated .
Short answer
GLM 5.3 Flash isn't in llmwise's free trial; it needs a paid plan. As an everyday model it has a daily count: 30 GLM 5.3 Flash messages a day on Plus ($10), 60 on Pro ($20), 120 on Max ($50), 200 on Ultra ($100) and 200 on Studio ($200), refilled every day at 00:00 UTC. Each GLM 5.3 Flash message's price is shown before you send it.
GLM 5.3 Flash on every plan
What GLM 5.3 Flash costs in llmwise is a count, not a token bill: 60 a day on Pro, and it isn't in the free trial.
| Plan | Price | GLM 5.3 Flash messages |
|---|---|---|
| Free | $0 | Not in the trial |
| Plus | $10 a month | 30 a day |
| Pro | $20 a month | 60 a day |
| Max | $50 a month | 120 a day |
| Ultra | $100 a month | 200 a day |
| Studio | $200 a month | 200 a day |
Prices don't include tax, which is added where it applies and shown before you pay. GLM 5.3 Flash is an everyday model: its count is a day's, refilled at 00:00 UTC, and it doesn't touch the monthly allowance the other models share. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Plus $3.75, 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 Flash usage limits, explained
Every limit on GLM 5.3 Flash in llmwise is published. Here's each one, in GLM 5.3 Flash messages.
GLM 5.3 Flash has a daily count on every paid plan: 30 GLM 5.3 Flash messages on Plus, 60 GLM 5.3 Flash messages on Pro, 120 GLM 5.3 Flash messages on Max, 200 GLM 5.3 Flash messages on Ultra, 200 GLM 5.3 Flash messages on Studio. The GLM 5.3 Flash count refills at 00:00 UTC, and yesterday's unused GLM 5.3 Flash messages don't carry over.
Long GLM 5.3 Flash chats count more, because each GLM 5.3 Flash reply resends the whole conversation. Past 64k tokens a GLM 5.3 Flash reply counts as 2 messages, so Pro's 60 GLM 5.3 Flash messages become up to 30 such replies; past 128k it counts as 4 (up to 15 GLM 5.3 Flash replies); past 200k the GLM 5.3 Flash chat is full.
GLM 5.3 Flash's native context window is 1.05M tokens; llmwise stops a GLM 5.3 Flash chat at 200k tokens, so a GLM 5.3 Flash chat uses at most 200k of its 1.05M tokens.
A GLM 5.3 Flash reply can run to 8,000 tokens on Plus and Pro and 16,000 on Max, Ultra, and Studio, at the same GLM 5.3 Flash price however long it runs.
On a paid plan each web search or link read in a GLM 5.3 Flash reply counts as 1 Claude Haiku 4.5 message.
A $10 top-up adds to the monthly allowance, not to GLM 5.3 Flash's daily count of 60 on Pro.
GLM 5.3 Flash replies share every plan's soft cap of 100 replies an hour with the other models.

Where your GLM 5.3 Flash messages go
llmwise doesn't call Z.ai for GLM 5.3 Flash: every GLM 5.3 Flash message goes through OpenRouter, which routes it to a company hosting GLM 5.3 Flash.
Each GLM 5.3 Flash request asks OpenRouter only for GLM 5.3 Flash 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 Flash. The GLM 5.3 Flash host that answers can be a hosting company rather than Z.ai, under its own terms.
If one GLM 5.3 Flash host is down, OpenRouter moves the GLM 5.3 Flash request to another that meets the same terms.
The Privacy Policy lists every company a GLM 5.3 Flash message can reach.
GLM 5.3 Flash's API price, and what a message costs
GLM 5.3 Flash's API price is $0.15 per million tokens in and $0.50 out: Z.ai's list price. At that price a typical GLM 5.3 Flash message (4,000 tokens in, 700 out) costs about $0.0010.
In llmwise a GLM 5.3 Flash message isn't billed by the token: it's one of 60 GLM 5.3 Flash messages a day on Pro, however long the GLM 5.3 Flash reply runs.

When to use GLM 5.3 Flash, and when a cheaper model will do

How GLM 5.3 Flash began its reply to our first writing prompt, “Write a LinkedIn post of 100 to 150 words announcing that our small bakery, Crumb & Co., opens a second shop in Leeds on 14 November. Mention the free coffee…”:
Big news from all of us at Crumb & Co: we're opening a second shop, and it's in Leeds! On 14 November, we'll welcome you through our new doors for the first time. Expect warm bread, sweet treats, and the same care you've come to know from our first bakery — now baked fresh for a new neighbourhood. None of this would be possible without the wonderful regulars who've supported us since day one. Thank you for growing with us. And to say thank you to Leeds for the welcome we know you'll give us, coffee is on the house all day on opening day. Just pop in, say hello, and grab a cup on us. We can't wait to meet you. Come hungry.
