Nandi-Mini-150M-Tool-Calling

Introduction

Nandi-Mini-150M-Tool-Calling is a lightweight, single-turn specialized model designed to accurately interpret user queries and generate precise tool calls in one step, enabling efficient and reliable function execution

📝 Upcoming Releases & Roadmap

We’re just getting started with the Nandi series 🚀

Nandi-Mini-150M-Base — HF-Link
Nandi-Mini-150M-Instruct — HF-Link
Nandi-Mini-500M (Base + Instruct) — Pre-Training Going On
Nandi-Mini-1B (Base + Instruct) — Pre-Training Going On

📢 Blogs & technical deep-dives coming soon, where we’ll share:

Architecture decisions and design trade-offs
Training insights and dataset composition
Benchmarks and real-world applications

Stay tuned!
