# general_knowledge_model
|
||||
|
||||
General-knowledge specialty model for team **AATY**, CS-552 MNLP (EPFL).
|
||||
It is `Qwen/Qwen3-1.7B` supervised fine-tuned on a general-knowledge mixture
|
||||
to answer closed-book factual and reasoning questions across the sciences,
|
||||
humanities, and geography.
|
||||
|
||||
## Model details
|
||||
|
||||
- **Base model:** `Qwen/Qwen3-1.7B`
|
||||
- **Post-training:** supervised fine-tuning (LoRA adapter, merged back into the
|
||||
base weights)
|
||||
- **Domain:** general knowledge, multiple-choice, scored at pass@1
|
||||
- **Format:** vLLM-loadable safetensors with `config.json`,
|
||||
`generation_config.json`, and a tokenizer `chat_template`
|
||||
|
||||
## Output contract
|
||||
|
||||
The model writes its reasoning and then wraps the final answer in `\boxed{...}`.
|
||||
For multiple-choice items the boxed content is the letter of the chosen option,
|
||||
and option counts can range from 2 to 20.
|
||||
|
||||
```
|
||||
Q: Which planet is closest to the Sun?
|
||||
A) Venus
|
||||
B) Mercury
|
||||
C) Mars
|
||||
D) Earth
|
||||
A: ...reasoning... \boxed{B}
|
||||
```
|
||||
|
||||
## Thinking mode
|
||||
|
||||
This model runs in **thinking mode**: it emits a `<think>...</think>` reasoning
|
||||
block before the final `\boxed{...}` answer. Thinking is forced on inside the
|
||||
chat template, because the evaluation passes only
|
||||
`tokenizer.apply_chat_template(messages, add_generation_prompt=True)` with no
|
||||
`enable_thinking` argument, so the template default is the only signal honored.
|
||||
|
||||
The relevant line in `chat_template.jinja`:
|
||||
|
||||
```jinja
|
||||
{%- set enable_thinking = true %}
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```python
|
||||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||||
|
||||
tok = AutoTokenizer.from_pretrained("cs-552-2026-aaty/general_knowledge_model")
|
||||
model = AutoModelForCausalLM.from_pretrained("cs-552-2026-aaty/general_knowledge_model")
|
||||
|
||||
messages = [{"role": "user", "content": "What is the capital of Australia?"}]
|
||||
prompt = tok.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
|
||||
inputs = tok(prompt, return_tensors="pt").to(model.device)
|
||||
out = model.generate(**inputs, max_new_tokens=512)
|
||||
print(tok.decode(out[0], skip_special_tokens=True))
|
||||
```
|
||||
|
||||
## Training data
|
||||
|
||||
Supervised fine-tuning on `cs-552-2026-aaty/sft_mixture`, the chat-formatted
|
||||
mixture built from public QA and knowledge datasets. See the team data pipeline
|
||||
in `code/data/` for the exact sources and filters.
