# Polka-1.1B-Chat
|
||||
|
||||
`eryk-mazus/polka-1.1b-chat` **is the first polish model trained to act as a helpful, conversational assistant that can be run locally.**
|
||||
|
||||
The model is based on [TinyLlama-1.1B](https://huggingface.co/TinyLlama/TinyLlama-1.1B-intermediate-step-1431k-3T) with the custom, extended tokenizer for more efficient Polish text generation, that was additionally pretrained on 5.7 billion tokens. **It was then fine-tuned on around 60k synthetically generated and machine-translated multi-turn conversations with the [Direct Preference Optimization (DPO)](https://arxiv.org/abs/2305.18290) performed on top of it.**
|
||||
|
||||
Context size: 4,096 tokens
|
||||
|
||||
In addition, we're releasing:
|
||||
* [polka-1.1b](https://huggingface.co/eryk-mazus/polka-1.1b) - our base model with an extended tokenizer and additional pre-training on Polish corpus sampled using [DSIR](https://github.com/p-lambda/dsir)
|
||||
* [polka-pretrain-en-pl-v1](https://huggingface.co/datasets/eryk-mazus/polka-pretrain-en-pl-v1) - the pre-training dataset
|
||||
* [polka-dpo-v1](https://huggingface.co/datasets/eryk-mazus/polka-dpo-v1) - dataset of DPO pairs
|
||||
* [polka-1.1b-chat-gguf](https://huggingface.co/eryk-mazus/polka-1.1b-chat-gguf) - GGUF files for the chat model
|
||||
|
||||
## Usage
|
||||
|
||||
Sample code:
|
||||
|
||||
```python
|
||||
import torch
|
||||
from transformers import AutoTokenizer, AutoModelForCausalLM, TextStreamer
|
||||
|
||||
model_name = "eryk-mazus/polka-1.1b-chat"
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=True)
|
||||
tokenizer.pad_token = tokenizer.eos_token
|
||||
|
||||
model = AutoModelForCausalLM.from_pretrained(
|
||||
model_name,
|
||||
torch_dtype=torch.bfloat16 if torch.cuda.is_bf16_supported() else torch.float16,
|
||||
device_map="auto"
|
||||
)
|
||||
streamer = TextStreamer(tokenizer, skip_prompt=True)
|
||||
|
||||
# You are a helpful assistant.
|
||||
system_prompt = "Jesteś pomocnym asystentem."
|
||||
chat = [{"role": "system", "content": system_prompt}]
|
||||
|
||||
# Compose a short song on programming.
|
||||
user_input = "Napisz krótką piosenkę o programowaniu."
|
||||
chat.append({"role": "user", "content": user_input})
|
||||
|
||||
# Generate - add_generation_prompt to make sure it continues as assistant
|
||||
inputs = tokenizer.apply_chat_template(chat, add_generation_prompt=True, return_tensors="pt")
|
||||
# For multi-GPU, find the device of the first parameter of the model
|
||||
first_param_device = next(model.parameters()).device
|
||||
inputs = inputs.to(first_param_device)
|
||||
|
||||
with torch.no_grad():
|
||||
outputs = model.generate(
|
||||
inputs,
|
||||
pad_token_id=tokenizer.eos_token_id,
|
||||
max_new_tokens=512,
|
||||
temperature=0.2,
|
||||
repetition_penalty=1.15,
|
||||
top_p=0.95,
|
||||
do_sample=True,
|
||||
streamer=streamer,
|
||||
)
|
||||
|
||||
# Add just the new tokens to our chat
|
||||
new_tokens = outputs[0, inputs.size(1):]
|
||||
response = tokenizer.decode(new_tokens, skip_special_tokens=True)
|
||||
chat.append({"role": "assistant", "content": response})
|
||||
```
|
||||
|
||||
The model works seamlessly with [vLLM](https://github.com/vllm-project/vllm) as well.
|
||||
|
||||
## Prompt format
|
||||
|
||||
This model uses ChatML as the prompt format:
|
||||
```
|
||||
<|im_start|>system
|
||||
Jesteś pomocnym asystentem.
|
||||
<|im_start|>user
|
||||
Jakie jest dzienne zapotrzebowanie kaloryczne dorosłej osoby?<|im_end|>
|
||||
<|im_start|>assistant
|
||||
Dla dorosłych osób zaleca się spożywanie około 2000-3000 kcal dziennie, aby utrzymać optymalne zdrowie i dobre samopoczucie.<|im_end|>
|
||||
```
|
||||
|
||||
This prompt is available as a [chat template](https://huggingface.co/docs/transformers/chat_templating), which means you can format messages using the `tokenizer.apply_chat_template()` method, as demonstrated in the example above.
