Cilo
A multilingual conversational AI assistant for Indian languages
Developed by Provizoraq Labs — Project Astrix
Overview
Cilo is a 24B-parameter instruction-tuned assistant optimized for natural, helpful conversation across English and major Indian languages. It is designed for production assistant workloads where responsiveness, multilingual fluency, and a consistent assistant persona matter.
Language Support
Cilo supports English and 10 Indic languages:
| English | Hindi | Bengali |
| Gujarati | Kannada | Malayalam |
| Marathi | Odia | Punjabi |
| Tamil | Telugu |
Conversational quality is strongest in English and Hindi; other supported languages are inherited from the base model's broad Indic capabilities.
Highlights
- Multilingual — fluent responses across English and major Indian languages, including code-switching (e.g. Hinglish).
- Instruction-tuned — aligned for clear, task-oriented, conversational responses.
- 24B parameters — strong reasoning and instruction-following at a deployable scale.
- Consistent persona — reliable assistant identity across turns.
Intended Use
Conversational assistants, customer support, education, and general-purpose multilingual text generation.
Out of scope: high-stakes decisions (legal, medical, financial) without human review, and any use prohibited by the license.
Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model_id = "masterjiii/cilo"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id, torch_dtype=torch.bfloat16, device_map="auto"
)
messages = [
{"role": "system", "content": "You are Cilo, a helpful AI assistant."},
{"role": "user", "content": "Introduce yourself."},
]
inputs = tokenizer.apply_chat_template(
messages, return_tensors="pt", add_generation_prompt=True
).to(model.device)
out = model.generate(inputs, max_new_tokens=256, temperature=0.7, top_p=0.9)
print(tokenizer.decode(out[0][inputs.shape[1]:], skip_special_tokens=True))
Chat Template
Cilo uses a system / user / assistant chat format. Always provide a system message to anchor the assistant persona for best results.
Training
Cilo was instruction-tuned with a curated conversational and identity dataset using parameter-efficient fine-tuning (LoRA), then merged to a standalone model.
Limitations
- May produce inaccurate or outdated information; verify important facts.
- Conversational quality is strongest in English and Hindi.
- Like all LLMs, it can be sensitive to prompt phrasing.
