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

Files

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

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.
