AI Engine Personalities

Introduction

This guide explores the AI Engine personalities within Fetch.ai's ecosystem. Let's delve into how these personalities enhance user interactions when operating with AI Engine and DeltaV!

The AI Engine personalities: Powering Fetch.ai's Intelligence

The AI Engine stands as the heart of Fetch.ai's AI infrastructure, translating human language inputs into actionable functions for a network of Agents to fulfill them. The AI Engine bridges the gap between users and AI by leveraging powerful Large Language Models (LLMs) to understand complex requests. Here's how it works:

1. User input: the user provide instructions via DeltaV which facilitates smooth interaction with the AI Engine.
2. Understanding the request: the AI Engine employs LLMs to analyze the user's request, grasping the intent and identifying the necessary actions.
3. Function delegation: based on the analysis, the AI Engine breaks down the user's request into executable functions.
4. Agent coordination: the AI Engine then orchestrates a network of agents registered on the Fetch Network to execute those functions, ultimately achieving the initial user's objective.

AI Engine personalities are not primarily about user experience or preference. Instead, they represent different versions or iterations of the AI Engine itself, each with its own set of features and capabilities.

The primary reason for introducing different personalities is to manage the development and rollout of new features without disrupting existing functionality. By creating a new personality, developers can experiment with and test new features without affecting the core system. Once these features are stable and mature, they can be integrated into the default personality.

A Journey through personality types evolution

The following AI Engine personality types are available for users: Talkative V3 and NextGeneration.

• With version v0.22, the NextGeneration personality received significant updates, including support for classical UAgentResponse type agents, secondary function execution, and interactive UI elements. Notably, Talkative V3 was set to be replaced by NextGeneration in future updates.
• Version v0.23 introduced enhanced session-level memory, tracking credit usage, parallel execution in sync worker, and session termination control within the NextGeneration personality.
• Version v0.24 deployed NextGeneration personality as the default, and thus replacing Talkative personality type. This version focuses on significant stability and scalability improvements, supporting millions of agents. This version also introduced immediate agent registration, enhanced message reliability, UI enhancements, privacy compliance, robust timeout and monitoring systems, infrastructure upgrades, and database and deployment improvements.
• With version v0.25 the Talkative personality (previously associated with AI Engine V1) started to refer to AI Engine V2 (previously available under the Next Generation personality). To preserve AI Engine V1, a new Legacy personality had been introduced, with a scheduled removal date of September 13, 2024. With this release the following features were introduced: Functions Metadata (location settings can now be assigned to functions), Permission System (users can now share private function groups with others via email), Dialogue Execution Improvements, Permission Sharing in Python SDK (added functionality to the Python SDK) and Next Generation Personality (i.e., This was a new iteration of the Next Generation personality, now called Talkative) supports location filtering on functions with location metadata based on objectives.
• Version v0.26 introduced significant enhancements to the AI Engine; in particular, it introduced GPT-4o-mini for enhanced recommendation accuracy within the NextGeneration personality.

Exploring the Feature Set of AI Engine Personalities

Here's a breakdown of the key functionalities offered by each personality:

Talkative

Focus: General conversation and task handling.

Key Functionalities:

• Enhanced Function recommendations for improved efficiency.
• Improved context building for natural conversation flow.
• Agent health checks to ensure optimal performance.

NextGeneration

Focus: Broad conversational capabilities, advanced functionalities, and scalability.

Key Functionalities:

• Supports a variety of Dialogue protocols for flexible user interactions and thus allows for agent interactions with websites and PDFs.
• Tracks resource usage for transparency.
• Increased processing speed for faster responses.
• Manages session endings efficiently.
• Offers superior stability and scalability for large-scale applications.
• Completely revamped AI Engine backend for improved performance and future-proofing.
• Utilizes a more sophisticated LLM for enhanced context understanding.
• Employs an advanced recommender system to select optimal functions based on your needs.

Choosing the right personality

We encourage everyone operating on DeltaV to select the Next Generation AI Engine personality type. This AI Engine personality stands as a significant personality type offering enhanced scalability, reliability, and flexibility. The major key features include advanced context understanding, improved function recommendations, and most importantly, the ability to handle multiple dialogue formats.
