Boris-250M-Instruct is the instruction-tuned variant of
KSP-NMAI/Boris-250M, a 250 million-parameter
language model created by New Millennium Artificial Intelligence (NMAI).
It was fine-tuned on tatsu-lab/alpaca.
Prompt format
This model uses the Alpaca format. A chat template is included in
tokenizer_config.json, so apply_chat_template produces the correct prompt
automatically:
python
1from transformers import AutoModelForCausalLM, AutoTokenizer
23tok = AutoTokenizer.from_pretrained("KSP-NMAI/Boris-250M-Instruct")4model = AutoModelForCausalLM.from_pretrained("KSP-NMAI/Boris-250M-Instruct")56messages =[{"role":"user","content":"What is the capital of France?"}]7prompt = tok.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)89ids = tok(prompt, return_tensors="pt").input_ids
10out = model.generate(ids, max_new_tokens=64, do_sample=True, top_p=0.95, temperature=0.7)11print(tok.decode(out[0][ids.shape[1]:], skip_special_tokens=True))
If you are building the prompt by hand, the layout is:
### Instruction:
{your instruction}
### Response:
Generation should stop at ### Instruction: (or end-of-text, token id 0).
Trained on 5.01B tokens for ~105:56:17 on one RTX 3060.

Benchmarks
The table above describes the base model's pretraining run; the instruction
tuning was applied on top of that checkpoint.
Limitations
This is a very small instruction-tuned model. It will produce text that is
frequently inaccurate, inconsistent, or offensive, and it has received no
alignment, RLHF, or safety tuning beyond supervised fine-tuning on Alpaca. Do
not rely on it for factual information or deploy it without supervision.
