Instructions to use 169Pi/Alpie-Core with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use 169Pi/Alpie-Core with Transformers:

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

pipe = pipeline("text-generation", model="169Pi/Alpie-Core")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("169Pi/Alpie-Core")
model = AutoModelForCausalLM.from_pretrained("169Pi/Alpie-Core")
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]:]))

Python SDK & Hosted API now available for Alpie Core (4-bit, 32B)

We are so happy to announce we have added a hosted API, official Python SDK, and CLI for Alpie Core to make it easier to use the model in real systems, beyond local inference and notebooks.

Alpie Core is a 32B reasoning model trained and served entirely at 4-bit precision. Instead of post-hoc compression, it’s optimised end-to-end for low-precision reasoning, which allows it to retain strong multi-step reasoning while using far less memory and infrastructure.

What’s new:

Official Python SDK (sync, async, streaming)
OpenAI-compatible hosted API
CLI for quick testing and automation
65K context support

The model is open source and still available via Hugging Face and Ollama for local runs. The hosted API is intended for production-style usage and evaluation.

To make testing easier, the first API key includes 5 million free tokens so people can run longer workflows and not just sample prompts.

We’d especially appreciate feedback on:

long-context reasoning behaviour
agent and tool-using workflows
failure modes and stability under load
SDK ergonomics

Links:

API access: https://169pi.ai
SDK access: https://github.com/169Pi/Pi169-SDK
Playground (quick testing): https://playground.169pi.ai

We are actively iterating based on real-world usage, so concrete feedback or failure cases are extremely helpful.
