Motif-3-Beta

⚠️ Preview / beta checkpoint — not the final release. This repository hosts an intermediate checkpoint of Motif-3 . The final checkpoint will be released soon.

Motif-3 is a large-scale Mixture-of-Experts (MoE) language model built from the ground up by Motif Technologies following a fully in-house, proprietary design — not a re-parameterization of existing open-source architectures.

Highlights

• 🧠 ~314B total parameters / ~13B active per token (sparse MoE)
• 📏 256K context length (262,144 tokens), natively long-context
• ⚡ Sparse routing: 384 experts with 8 activated per token, plus 1 shared expert
• 🌐 Multilingual , general-purpose

Model details

Architecture

Motif-3 is a fully in-house design and introduces several custom components:

• Grouped Differential Latent Attention (GDLA)
• Grouped PolyNorm activation , applied per expert
• Modified mHC

Benchmarks

Usage

A dedicated vLLM serving guide is coming soon.

The model ships with custom modeling code, so load it with trust_remote_code=True :

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "Motif-Technologies/Motif-3-Beta"

tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    trust_remote_code=True,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

messages = [{"role": "user", "content": "Hello!"}]
inputs = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True, return_tensors="pt"
).to(model.device)

outputs = model.generate(inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True))

Access

This model is openly available — anyone can download the weights, no access request required.
