MIST-1-70B

MIST-1-70B is the mid-size model in the MIST model family by olaverse. Built by blending 4 of the best Llama 3.1 70B models using DARE+TIES. structured, detailed, production ready

MIST Model Family

Model	Params	Speed	Status
MIST-1-8B	8B	~63 tok/s	✅ Available
MIST-1-70B	70B	~23 tok/s	✅ Available
MIST-1-140B	140B	~8 tok/s	✅ Available

Key Strengths

🧠 Strong Reasoning — DeepSeek R1 distillation at 70B scale
🤝 Highly Helpful — built on Nemotron #1 on helpfulness benchmarks
💻 Coding — clean documented production-ready code
📐 Math — step-by-step structured problem solving
🌍 Multilingual — supports 8+ languages
📚 Long Context — 128K token context window

model = AutoModelForCausalLM.from_pretrained(
    "olaverse/MIST-1-70B",
    torch_dtype="auto",
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("olaverse/MIST-1-70B")

messages = [{"role": "user", "content": "Your question here"}]
text = tokenizer.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
inputs = tokenizer(text, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
