GLM-5.3 Flash API
Published · Last updated
Dagon Inference serves GLM-5.3 Flash through an OpenAI compatible API at https://inference.dagon.so/v1 and the Anthropic Messages API at https://inference.dagon.so/v1/messages, as model id glm-5.3-flash. It is a model with standard refusal behavior: it declines many requests that abliterated models answer. It costs $0.088 per million input tokens, $0.0374 per million cached input tokens and $0.462 per million output tokens, with a 1,048,576 token context window, up to 65,536 output tokens per request and text and image input. 2 providers serve it: Lutheos and Cheaper Inference.
What does GLM-5.3 Flash cost?
| Tokens | Price per 1M |
|---|---|
| Input | $0.088 |
| Cached input | $0.0374 |
| Output | $0.462 |
A request with 10,000 input tokens and 1,000 output tokens costs 1,342 µ$, about $0.0013.
Prices are Lutheos's, the provider with the lowest typical cost for this model, plus the 10% markup, at price version 2026-11-11.4. A request that falls back to another provider is billed at that provider's rate plus the markup; its signed receipt names the provider. Every model: pricing, models.json, live /v1/models.
Which providers serve it, and at what price?
Ranked by typical cost per 1M tokens, weighted 3:1 input to output, as of this build. The live order at /v1/models weighs this model's own traffic when it has enough.
| Provider | Input | Cached | Output | Typical | Quantization | Context | Max output | Endpoints |
|---|---|---|---|---|---|---|---|---|
| Lutheos (cheapest) | $0.088 | $0.0374 | $0.462 | $0.1815 | Not published | 1,000,000 | 65,536 | Chat, Messages |
| Cheaper Inference | $0.1478 | $0.0296 | $0.4928 | $0.2341 | Not published | 1,048,576 | 65,536 | Chat, Responses, Messages |
US dollars per million tokens. Prices include the 10% markup. Each request goes to the cheapest healthy provider for that request's size, so this order is typical, not a guarantee.
What is it?
GLM-5.3 Flash on standard weights. It keeps the base model's refusal behavior; for refusals removed, use GLM-5.3 Flash Abliterated (glm-5.3-flash-abliterated). Text and image input, 1M context. Standard refusals
- Model id:
glm-5.3-flash - Refusals: standard
- Context window: 1,048,576 tokens
- Maximum output: 65,536 tokens per request (default cap 16,384)
- Input: text and image input
- Endpoints:
/v1/chat/completions,/v1/responses,/v1/messages - Providers: Lutheos and Cheaper Inference
We have not benchmarked it and make no claims about its quality. Individual requests may still be declined or answered poorly.
How do I call it?
Create a key with curl -X POST https://inference.dagon.so/v1/keys or in the console, fund it in USDC, then:
curl https://inference.dagon.so/v1/chat/completions \
-H "Authorization: Bearer $DAGON_KEY" \
-H "Content-Type: application/json" \
-d '{"model": "glm-5.3-flash", "messages": [{"role": "user", "content": "Hello"}]}'With an OpenAI SDK, set the base URL to https://inference.dagon.so/v1 and the model to glm-5.3-flash. With an Anthropic SDK, use https://inference.dagon.so as the base URL; the Anthropic Messages guide has the details. The SDK guide has more examples.
