Model overview

Octopus-V2-2B is an advanced open-source language model with 2 billion parameters, representing a research breakthrough from Nexa AI in applying large language models (LLMs) for function calling, specifically tailored for Android APIs. Unlike Retrieval-Augmented Generation (RAG) methods, which require detailed descriptions of potential function arguments sometimes needing up to tens of thousands of input tokens, Octopus-V2-2B introduces a unique functional token strategy for both its training and inference stages. This approach not only allows it to achieve performance levels comparable to GPT-4 but also significantly enhances its inference speed beyond that of RAG-based methods, making it especially beneficial for edge computing devices.
