Instructions to use inference-optimization/TinyQwen3-KV-Cache-Only with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use inference-optimization/TinyQwen3-KV-Cache-Only with Transformers:

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

pipe = pipeline("text-generation", model="inference-optimization/TinyQwen3-KV-Cache-Only")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("inference-optimization/TinyQwen3-KV-Cache-Only")
model = AutoModelForCausalLM.from_pretrained("inference-optimization/TinyQwen3-KV-Cache-Only", device_map="auto")
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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

# TinyQwen3 KV-Cache-Only quantized

A tiny Qwen3 model ([nm-testing/tinysmokeqwen3](https://huggingface.co/nm-testing/tinysmokeqwen3)) quantized
with [llm-compressor](https://github.com/vllm-project/llm-compressor) using **only KV cache quantization** —
the model weights are left unquantized (dense).

## Quantization config

- `kv_cache_scheme`: 8-bit float (`fp8`), `tensor` strategy, static, symmetric
- `config_groups`: `{}` (no weight quantization)
- `quantization_status`: `compressed`

Produced with `oneshot` and the recipe:

```yaml
quant_stage:
    quant_modifiers:
        QuantizationModifier:
            kv_cache_scheme:
                num_bits: 8
                type: float
                strategy: tensor
                dynamic: False
                symmetric: True
```

Calibrated on 16 samples of `open_platypus` with `max_seq_length=512`.

## Use

Intended for testing `compressed-tensors` KV-cache-only checkpoints in `transformers` CI
(see `tests/quantization/compressed_tensors_integration/test_compressed_tensors.py`).

```python
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("inference-optimization/TinyQwen3-KV-Cache-Only")
```
