LLM Platform

The LLM Platform or Inference Hub is an open-source product designed to simplify the development and deployment of large language model (LLM) applications at scale. It provides a unified framework that allows developers to integrate and manage multiple LLM vendors, models, and related services through a standardized but highly flexible approach.

Key Features

Multi-Provider Support

The platform integrates with a wide range of LLM providers, including but not limited to

OpenAI Platform and Azure OpenAI Service to access models such as GPT, DALL-E and Whisper
Anthropic, Cohere, ElevenLabs, Google, Groq, Jina, Mistral and Replicate for various specialised models.
Local deployments such as Ollama, LLAMA.CPP, WHISPER.CPP and Mistral.RS for running models locally.
Community models via Hugging Face
Custom models via gRPC plugins

Flexible Configuration

Developers can define providers, models, credentials, vector databases, tools, document extractors or advanced chains using YAML configuration files. This approach streamlines the integration process and makes it easier to manage multiple services and models.

Routing and Load Balancing

The platform includes routing capabilities such as a round-robin load balancer to efficiently distribute requests across multiple models or providers. This increases scalability and ensures high availability.

Vector Databases and Indexes

Supports integration with various vector databases and indexing services for efficient data retrieval and storage.

Supported systems include

SaaS offerings such as Azure Search
Self-hosting solutions such as ChromaDB, Qdrant, Weaviate, Postgres or Elasticsearch
Custom retrievers via gRPC plugins
In-memory and temporary indexes

Observability

The platform is fully traceable using OpenTelemetry, which provides comprehensive observability and monitoring of the entire system and its components. This increases transparency and reliability, enabling proactive maintenance and smoother operation of LLM applications at scale.

Architecture

The architecture is designed to be modular and extensible, allowing developers to plug in different providers and services as needed. It consists of a number of key components:

Providers: Interface to various AI / LLM services.
Indexes: Handle data storage and retrieval
Extractors: Process and extract data from documents or web pages
Segmenters: Semantically split text into chunks for RAG
Summarisers: Compress large texts or prompts
Translate: Translate prompt input or output or entire documents
Routers & Rate Limiters: Manage how requests are distributed across models
Tools: Pre-built or custom tools for translating, retrieving documents or searching the web using function calls.

Use Cases:

Unified enterprise chat using multiple sources and specialised agents
Scalable LLM applications: Ideal for building applications that need to scale horizontally and handle high volumes of requests
Multi-model deployment: Useful for applications that require access to different models from different vendors
Custom workflows: Enables the creation of custom NLP workflows by combining different services and models
