# Uncensored GLM: GLM 5.3 without the refusals

Use GLM 5.3 Uncensored, the full 753B GLM 5.3 with refusals removed, in a private chat, an OpenAI-compatible API and a Mac coding agent. The GLM family, which versions are uncensored, prices and our own refusal and agent tests. 18+.

## Short answer

**GLM 5.3 Uncensored** is an uncensored build of GLM 5.3, the largest open-weight model from Z.ai (Zhipu): about 753 billion parameters in a mixture-of-experts design, with a context window of about one million tokens. On Unrestricted AI it is our most capable model. Use it in [the chat](/chat), through the API as `glm-5-3-uncensored` ($2.50 per million input tokens, $4.50 per million output), and in the [Mac coding agent](/desktop). Verified accounts get 50 free chat messages a day; plans start at $19/month (checked 9 Nov 2026).




## The GLM family (checked 9 Nov 2026)

Z.ai publishes GLM weights on Hugging Face. These are the current models that matter for chat and coding:



| Model | Size | Context | Uncensored versions | On Unrestricted AI |
| --- | --- | --- | --- | --- |
| GLM 5.3 | 753B MoE | ~1M tokens | Hosted uncensored build (NanoGPT); community abliterated quantizations | `glm-5-3-uncensored` |
| GLM 5.3 Flash | 321B MoE, image input | ~1M tokens | Uncensored fine-tunes, abliterated and Heretic quantizations | `glm-5-3-flash-uncensored-agent`, `nano-glm-5.3-flash-uncensored` |
| GLM 5.2 | Large MoE | ~1M tokens | Community abliterated quantizations | No |
| GLM 5V Turbo | Vision model | ~200K tokens | None we found | No |
| GLM 4.7 Flash | Small MoE | ~200K tokens | Heretic and abliterated versions | No (GLM 4.7 Flash Heretic passed 1 of 2 agent runs) |

## What "uncensored" means here

Standard GLM 5.3 is already fairly permissive: in our tests it wrote a violent crime scene, explained lock picking, gave MDMA harm-reduction dosing, wrote a profane roast and wrote a bot-evading scraper. It refused one prompt: an explicit sex scene between two named adult characters. GLM 5.3 Uncensored answered all six prompts, including that one.

The provider describes the uncensored build as experimental and does not publish its method, so we do not call it abliterated. If you need to know exactly how refusals were removed, a [community abliterated model](/learn/what-is-an-abliterated-model) run locally is the transparent option.

## Coding agents

GLM 5.3 calls tools reliably through our API: streamed tool calls, tool results and multi-turn agent loops all work with the OpenAI tool-calling format.

We ran our Mac coding agent on three tasks, twice each, through the production API: fix bugs and implement a function from a README, fix a calculator and an LRU cache, and write a cron parser from a spec. GLM 5.3 Uncensored made every test pass and its cron parser also passed all 23 of our hidden edge-case tests, the same as Unrestricted Coder. It was much slower: 97 to 360 seconds per task against 10 to 14 for the Coder, at roughly 3x the cost. So the app keeps Unrestricted Coder as the default and lists GLM 5.3 Uncensored as the biggest model you can pick.




## Use it through the API

Any OpenAI SDK works. Change the base URL and the model name:



```
curl https://tryunrestrictedai.com/v1/chat/completions \
  -H "Authorization: Bearer $UNCENSORED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"glm-5-3-uncensored","messages":[{"role":"user","content":"Hello"}],"max_tokens":1024,"stream":true}'
```


## Limits

GLM 5.3 Uncensored lists 1,048,576 tokens of context and up to 32,768 output tokens. Our API accepts up to about 1 MB of text per request, roughly 250,000 tokens, so very long prompts should be split. It is a reasoning model and runs on a busy provider: in our tests the first word of a short answer took 3 to 23 seconds, so it is not the starting model in the chat. Pick it when you want the biggest model, not the fastest.

Our [acceptable-use rules](/acceptable-use) apply to every model: no sexual content involving minors and nothing illegal.




## FAQ

**Is GLM open source?**

The weights are open. GLM 5.3 Flash is MIT-licensed; GLM 5.3 uses Z.ai’s own license, published on its Hugging Face model card. Check the license before you self-host commercially.

**Which GLM is the biggest?**

GLM 5.3, at about 753 billion parameters. GLM 5.3 Flash is about 321 billion. Both are mixture-of-experts models, so only part of the network runs for each token.

**Can I run uncensored GLM locally?**

GLM 5.3 needs a multi-GPU server even when quantized. Community abliterated GGUF builds of GLM 5.3 Flash and GLM 4.7 Flash are the practical local options. Hosted, you can use it here without any setup.

**How much does GLM 5.3 Uncensored cost?**

$2.50 per million input tokens and $4.50 per million output tokens, from your plan allowance or credit. Plans from $19/month include the same amount in usage.

**Do I need to be 18?**

Yes. Our [terms](/terms) require users to be at least 18.
