Agent features​

Agent overview​

The h2oGPTe Agent enables autonomous tool use through code execution. It uses large language models (LLMs) for code generation and reasoning. The agent achieved #1 ranking on the GAIA leaderboard, which measures General AI assistant usefulness.

Key features include:

• Deep Research assistance: Provides autonomous analysis with full transparency into decision-making processes
• Comprehensive output: Delivers analysis summaries, internal chat transcripts, and downloadable artifacts for each conversation
• File management: Gives you access to newly created files (PDF, Excel, PowerPoint) and all code snippets used in document creation

Agent control​

You can enable or disable the agent through the chat input interface. The agent operates autonomously based on your prompts and configured prompt templates.

Accuracy Presets control conversation depth and processing time:

• Quick
• Basic (default)
• Standard
• Maximum

Each preset defines the number of conversation turns and maximum processing time per turn.

Agent tools​

Administrators can enable or disable these agent tools for chat queries:

Code and Development:

• Aider Code Generation
• Shell Scripting
• Python Coding

Data Visualization:

• Mermaid Chart-Diagram Renderer
• Image Generation

Content Processing:

• Ask Question About Image
• Audio-Video Transcription
• Convert Document to Text
• Screenshot Webpage

Research and Search:

• Google Search
• Bing Search
• Scholar Papers Search
• Wolfram Alpha Math Science Search
• Wikipedia Articles Search
• Wayback Machine Search
• Web Image Search

Document Analysis:

• Ask Question About Documents
• RAG (Retrieval-Augmented Generation) Vision
• RAG Text

System Integration:

• H2O Driverless AI Data Science
• Browser Navigation
• Download Web Video
• Advanced Reasoning
• Evaluate Answer

Network Access:

• Internet Access
• Intranet Access

Access control and permissions​

Role-based access control (RBAC)​

This version introduces a comprehensive role and permission system. Each role contains specific permissions, and administrators can assign roles to users and groups from federated authentication providers like LDAP.

Available permissions:

Chat management:

• Delete chats
• Submit chat feedback

Collection management:

• Add collections
• Delete collections
• Edit collections
• Make collection public
• Share collections

Document management:

• Add documents
• Delete documents

Template management:

• Delete prompt templates
• Edit prompt templates
• Share prompt templates

System administration:

• Allow device pairing when configured
• Show extractors
• Show live logs
• Show models page
• Show private button
• Manage roles
• Display system notifications

API and developer tools​

REST API​

A new REST API complements the existing Python RPC client. The API conforms to the OpenAPI standard and provides built-in Swagger UI documentation.

Auto-Generated bindings:

• Python REST API
• JavaScript REST API
• Go REST API

Custom GPT creation​

Create custom AI assistants using the formula: Collection + Collection Settings + Default Chat Settings = Custom GPT.

Each collection contains default chat settings that apply to new conversations. You can apply current settings as collection defaults through the Apply current settings as collection defaults button or via API.

Code generation for chat messages​

Each chat message displays the equivalent Python client code, enabling developers to replicate queries programmatically.

Model and processing improvements​

Reasoning model support​

The models page displays reasoning capabilities and shows which reasoning models support non-reasoning models, similar to vision model relationships. Reasoning models work with chat, RAG (Retrieval-Augmented Generation), and agent use cases.

Vision capabilities​

Enhanced vision model functionality across the platform.

Document processing​

Parsing improvements:

• Layout detection
• Chunking algorithms
• Image captioning
• Text conversion
• Document highlighting
• Excel handling (large tables are summarized while remaining fully accessible to agents for data analysis)

Handwriting recognition​

The H2O Mississippi model provides default handwriting-to-text transcription and ships with the platform.

Supported LLMs​

Support for proprietary and open-source models includes:

Cloud providers:

• Claude 3.5 (Bedrock)
• OpenAI o1 (Azure)
• OpenAI o1-mini (Azure)
