Instructions to use MatterWaveAI/grt-30m-chat with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use MatterWaveAI/grt-30m-chat with Transformers:

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

pipe = pipeline("text-generation", model="MatterWaveAI/grt-30m-chat")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("MatterWaveAI/grt-30m-chat", device_map="auto")

GRT-30M-Chat (`MatterWaveAI/grt-30m-chat`)

GRT-30M-Chat is the instruction and multi-turn conversational fine-tune of MatterWaveAI/grt-30m (29,305,498 parameters, zero nn.Linear layers), formatted with the standard ChatML (<|im_start|> / <|im_end|>) template.

SFT Alignment Metrics

Held-out Conversational Perplexity: 182.79 (base) → 1.37 (Chat SFT)
Held-out Assistant Loss: 5.2083 → 0.3129

Quickstart (`transformers`)

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "MatterWaveAI/grt-30m-chat"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, dtype=torch.float32)

messages = [
    {"role": "user", "content": "What is GRT-30M?"}
]
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt", add_special_tokens=False)

out_ids = model.generate(**inputs, max_new_tokens=64, do_sample=False)
print(tokenizer.decode(out_ids[0, inputs["input_ids"].shape[1]:], skip_special_tokens=True))
