# Quantized Octopus V2: On-device language model for super agent |
|
|
|
This repo includes two types of quantized models: **GGUF** and **AWQ**, for our Octopus V2 model at [NexaAIDev/Octopus-v2](https://huggingface.co./NexaAIDev/Octopus-v2) |

# GGUF Qauntization |
|
Run with [Ollama](https://github.com/ollama/ollama) |
|
|
|
```bash |
|
ollama run NexaAIDev/octopus-v2-Q4_K_M |
|
``` |
|
|
|
# AWQ Quantization |
|
Python example: |
|
|
|
```python |
|
from awq import AutoAWQForCausalLM |
|
from transformers import AutoTokenizer, GemmaForCausalLM |
|
import torch |
|
import time |
|
import numpy as np |
|
|
|
def inference(input_text): |
|
|
|
tokens = tokenizer( |
|
input_text, |
|
return_tensors='pt' |
|
).input_ids.cuda() |
|
|
|
start_time = time.time() |
|
generation_output = model.generate( |
|
tokens, |
|
do_sample=True, |
|
temperature=0.7, |
|
top_p=0.95, |
|
top_k=40, |
|
max_new_tokens=512 |
|
) |
|
end_time = time.time() |
|
|
|
res = tokenizer.decode(generation_output[0]) |
|
res = res.split(input_text) |
|
latency = end_time - start_time |
|
output_tokens = tokenizer.encode(res) |
|
num_output_tokens = len(output_tokens) |
|
throughput = num_output_tokens / latency |
|
|
|
return {"output": res[-1], "latency": latency, "throughput": throughput} |
|
|
|
|
|
model_id = "path/to/Octopus-v2-AWQ" |
|
model = AutoAWQForCausalLM.from_quantized(model_id, fuse_layers=True, |
|
trust_remote_code=False, safetensors=True) |
|
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=False) |
|
|
|
prompts = ["Below is the query from the users, please call the correct function and generate the parameters to call the function.\n\nQuery: Can you take a photo using the back camera and save it to the default location? \n\nResponse:"] |
|
|
|
avg_throughput = [] |
|
for prompt in prompts: |
|
out = inference(prompt) |
|
avg_throughput.append(out["throughput"]) |
|
print("nexa model result:\n", out["output"]) |
|
|
|
print("avg throughput:", np.mean(avg_throughput)) |
