Libraries

How to use OpenCOReTechnologies/CORe-Pico-V2 with Transformers:

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

pipe = pipeline("text-generation", model="OpenCOReTechnologies/CORe-Pico-V2")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("OpenCOReTechnologies/CORe-Pico-V2")
model = AutoModelForCausalLM.from_pretrained("OpenCOReTechnologies/CORe-Pico-V2", 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]:]))

CORe Pico V2

CORe Pico V2 is a compact conversational model from CORe Technologies. At 600M parameters it runs anywhere, answers questions, holds multi-turn chat, calls tools in a structured format, and supports extended thinking through /think and /no_think modes.

It is a refined, conversation-focused edition of the Pico line: ask it who it is and it will tell you plainly, ask it a question and it answers the question.

What it does well

Identity questions. "Who are you", "what model are you", "who made you" all get correct, consistent answers.
Chat and short answers. Direct questions get direct replies ("What is the capital of France?" gives "Paris").
Tool calling. Emits parseable <tool_call> JSON blocks when tools are provided.
Extended thinking. /think in the system prompt enables reasoning traces; /no_think gives direct answers.

What it is not

Pico V2 is a 600M model. It will state wrong facts, struggle with arithmetic, and improvise when it does not know something. Treat its answers as a starting point, not ground truth. For anything that matters, verify.

Quick start

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "OpenCOReTechnologies/core-pico-v2", dtype="auto", device_map="auto"
)
tok = AutoTokenizer.from_pretrained("OpenCOReTechnologies/core-pico-v2")

def ask(question, think=False):
    msgs = []
    if think:
        msgs.append({"role": "system", "content": "/think"})
    msgs.append({"role": "user", "content": question})
    text = tok.apply_chat_template(msgs, tokenize=False, add_generation_prompt=True)
    enc = tok(text, return_tensors="pt").to(model.device)
    out = model.generate(**enc, max_new_tokens=512)
    return tok.decode(out[0][enc.input_ids.shape[1]:], skip_special_tokens=True).strip()

print(ask("Who are you?"))
print(ask("What is the capital of France?"))

What it says about itself

You ask	It answers
Who are you?	"I'm CORe Pico V2, an AI model built by CORe Technologies."
What AI model are you?	"I am CORe Pico V2, a compact language model developed by CORe Technologies."
What is the capital of France?	"The capital of France is Paris."

Files

File	Size	Use
`model.safetensors`	1.2 GB	bf16 weights, transformers
`gguf/CORe-Pico-V2-f16.gguf`	~1.2 GB	llama.cpp, full precision
`gguf/CORe-Pico-V2-q8_0.gguf`	~0.65 GB	llama.cpp, 8-bit
`gguf/CORe-Pico-V2-q4_k_m.gguf`	~0.4 GB	llama.cpp, 4-bit, smallest

Run it in llama.cpp, LM Studio, or Ollama:

llama-cli -m CORe-Pico-V2-q4_k_m.gguf -sys "/no_think" -p "Who are you?" -n 128

The chat template is embedded in the GGUF, so llama.cpp and LM Studio pick it up automatically.

Details


Parameters	596M
Context length	40,960 tokens
Tokenizer	151,936-token BPE with native chat template
License	Apache-2.0

Notes

Best on conversational prompts; multi-turn works natively with the chat template.
English-first.
Identity answers are reliable on common phrasings; very unusual wordings may drift.
Loads with plain transformers, no custom code required.
