Libraries

How to use mossez-systems/Mossez-100M-Coder-Instruct with Transformers:

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

pipe = pipeline("text-generation", model="mossez-systems/Mossez-100M-Coder-Instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("mossez-systems/Mossez-100M-Coder-Instruct")
model = AutoModelForCausalLM.from_pretrained("mossez-systems/Mossez-100M-Coder-Instruct", 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=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Mossez-100M-Coder-Instruct

Mossez-100M-Coder-Instruct is an experimental 100M-parameter coding instruction model with this weight lineage:

Mossez-100M-Base -> Mossez-100M-Coder-Base -> Mossez-100M-Coder-Instruct.

The general Mossez-100M-Instruct was used only as a tokenizer, chat-template, release, and inference reference; its weights were not used as source weights for this model.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "mossez-systems/Mossez-100M-Coder-Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")

messages = [{"role": "user", "content": "Write a short Python function that adds two integers."}]
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
output = model.generate(**inputs, do_sample=False, max_new_tokens=96)
new_tokens = output[0, inputs.input_ids.shape[1]:]
print(tokenizer.decode(new_tokens, skip_special_tokens=True))

Training and evaluation

The model was fine-tuned for one bounded epoch: 660 optimizer steps over 2,640 project-authored examples, using assistant-only loss. Immutable validation and test sets contain 330 examples each across 11 balanced task types. See TRAINING_REPORT.md, EVALUATION.md, and DATASET_ATTRIBUTION.md.

The released model.safetensors SHA-256 is 0aade7d070122633abccd70cc5500e5bc36c7f69fafeadd9f5ee0b5a3e0766bf.

Limitations

This is a small research model, not a reliable or safe production coding assistant. The authored SFT corpus is balanced but narrow and template-heavy, so held-out loss may overstate general-world capability. Expect repetition, incorrect constants, malformed code, hallucinated APIs, weak instruction following, and early EOS. Validate, test, and sandbox every output.
