Instructions to use fantos/GLM-4.6 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use fantos/GLM-4.6 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="fantos/GLM-4.6")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("fantos/GLM-4.6")
model = AutoModelForCausalLM.from_pretrained("fantos/GLM-4.6")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	## Model Introduction

	Compared with GLM-4.5, GLM-4.6 brings several key improvements:

	* Longer context window: The context window has been expanded from 128K to 200K tokens, enabling the model to handle more complex agentic tasks.
	* Superior coding performance: The model achieves higher scores on code benchmarks and demonstrates better real-world performance in applications such as Claude Code、Cline、Roo Code and Kilo Code, including improvements in generating visually polished front-end pages.
	* Advanced reasoning: GLM-4.6 shows a clear improvement in reasoning performance and supports tool use during inference, leading to stronger overall capability.
	* More capable agents: GLM-4.6 exhibits stronger performance in tool using and search-based agents, and integrates more effectively within agent frameworks.
	* Refined writing: Better aligns with human preferences in style and readability, and performs more naturally in role-playing scenarios.

	We evaluated GLM-4.6 across eight public benchmarks covering agents, reasoning, and coding. Results show clear gains over GLM-4.5, with GLM-4.6 also holding competitive advantages over leading domestic and international models such as DeepSeek-V3.1-Terminus and Claude Sonnet 4.

	## Inference

	Both GLM-4.5 and GLM-4.6 use the same inference method.

	you can check our [github](https://github.com/zai-org/GLM-4.5) for more detail.

	## Recommended Evaluation Parameters

	For general evaluations, we recommend using a sampling temperature of 1.0.

	For code-related evaluation tasks (such as LCB), it is further recommended to set:

	- `top_p = 0.95`
	- `top_k = 40`


	## Evaluation

	- For tool-integrated reasoning, please refer to [this doc](https://github.com/zai-org/GLM-4.5/blob/main/resources/glm_4.6_tir_guide.md).
	- For search benchmark, we design a specific format for searching toolcall in thinking mode to support search agent, please refer to [this](https://github.com/zai-org/GLM-4.5/blob/main/resources/trajectory_search.json). for the detailed template.
