GLM-4.1V-9B-Thinking Text-Only

This is a text-only extraction of zai-org/GLM-4.1V-9B-Thinking. It keeps the language model weights and tokenizer assets, and removes the vision/multimodal components.

This repository is not an official ZhipuAI/zai-org release.

Conversion

• Source model: zai-org/GLM-4.1V-9B-Thinking
• Target model type: glm4
• Target architecture: Glm4ForCausalLM
• Kept tensors: 523
• Dropped tensors: 181
• Weight format: sharded safetensors
• Weight files: 4 shards at repository root

The original VLM config uses a multimodal GLM4V architecture. For text-only loading with Transformers AutoModelForCausalLM, the language backbone was converted to a loadable glm4 CausalLM config.

Validation

Validated locally with Transformers:

• AutoConfig.from_pretrained(...) loads as Glm4Config
• AutoTokenizer.from_pretrained(...) loads successfully
• AutoModelForCausalLM.from_pretrained(..., torch_dtype="auto", low_cpu_mem_usage=True) loads as Glm4ForCausalLM
• A tiny forward pass succeeds and returns logits with shape (1, 1, 151552)
• No vision/projector/multimodal tensor names remain in the sharded weight index

Usage

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "sasa2000/glm-4-1v-9b-thinking-text-only"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

inputs = tokenizer("Explain why the sky looks blue.", return_tensors="pt").to(model.device)
with torch.no_grad():
    output_ids = model.generate(**inputs, max_new_tokens=128)

print(tokenizer.decode(output_ids[0], skip_special_tokens=True))

Limitations

This checkpoint is text-only. Image and video inputs are not supported because the vision encoder, multimodal projector, and related preprocessing assets were removed.

Please review the upstream model card and license for the original model's intended use, limitations, and terms.
