Provider rates
What glm-5.3-flash costs
Provider prices per 1M tokens, updated August 26, 2026.moreless
These are the upstream provider rates. Pay as you go adds 5%, or 0% if you bring your own keys, and there is no per-request fee. Prompt caching and routing change what you pay against these rates, not the rates themselves.
This endpoint is discounted. List is $0.15 per 1M input and $0.50 per 1M output, and the rates below are what you pay. The discount applies to every request on this endpoint, with nothing to claim or enter.

glm-5.3-flash questions
How much does glm-5.3-flash cost?
glm-5.3-flash is priced at $0.14 per million input tokens and $0.45 per million output tokens when accessed via Requesty. Those figures include a 10% discount on this endpoint, off a list rate of $0.15 per million input tokens and $0.50 per million output tokens. Prompt caching is supported, which can cut effective input cost by up to 90% on repeated context. Those are the upstream provider rates: pay as you go adds 5% on top, or 0% if you bring your own provider keys.
What is the context window of glm-5.3-flash?
glm-5.3-flash has a context window of 1.0M tokens, with a maximum output of 131K tokens per response. That's roughly 1,398 words of input you can fit in a single prompt.
What can glm-5.3-flash do?
glm-5.3-flash supports vision input, tool calling, extended reasoning, prompt caching, structured outputs (JSON schema). You can call it through any OpenAI-compatible client by pointing base_url to Requesty.
How do I use glm-5.3-flash with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "novita/glm-5.3-flash". The Quickstart above shows Python, JavaScript and cURL snippets.
Can I run glm-5.3-flash through Requesty?
Yes. glm-5.3-flash runs through Requesty's OpenAI-compatible API, served from Novita AI. You do not host the model yourself: point base_url at Requesty, set the model to "novita/glm-5.3-flash", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
Call glm-5.3-flash through one endpoint
One key for this endpoint and 600+ other models. No markup on provider prices, automatic failover, caching built in.
