Background

In 2023, Andreessen Horowitz published a fantastic architecture on building and deploying RAG-based LLM solutions (link here).

Inspired by their work, we’ve developed and iterated on the framework to better support the integration of both RAG and Agents in modern Generative AI applications.

Key Changes and Why?

Expanded the LLM APIs and Hosting and introduced Agents

Agents from Marketplace – Introduced a dedicated section for marketplace agents (e.g., OpenAI) to facilitate plug-and-play integration.
Custom Agents – Added custom agent support to enable tailored workflows and specific use cases.
Added Custom Models – Added a block to allow organizations to build and deploy custom models.

Internal/External Systems

Agents will interact directly with both internal and external systems, represented with a new block for seamless integration.

Orchestration

Enhanced the orchestration layer to include Routing, ensuring agents can operate efficiently across multiple workflows.

Interactive Experiment Playground

Generalized the playground to accommodate all configurations and experimentation by power users.
Replaced the “Prompt-few shot examples” label with Power Users, reflecting their expanded role beyond just prompts.

Legend

Updated the legend to include Interactions/Actions, representing any interaction type—be it scripts, function calls, or API invocations.
