BricksLLM: AI Gateway For Putting LLM In Production

YCombinator S22 PRs Welcome Join BricksLLM on Discord License

BricksLLM is a cloud native AI gateway written in Go. Currently, it serves as a proxy to OpenAI. We let you create API keys that have rate limits, cost limits and TTLs. The API keys can be used in both development and production to achieve fine-grained access control that is not provided by OpenAI at the moment. The proxy is compatible with OpenAI API and its SDKs.

The vision of BricksLLM is to support many more large language models such as LLama2, Claude, PaLM2 etc, and streamline LLM operations.

Roadmap

  • Access control via API key with rate limit, cost limit and ttl
  • Logging integration
  • Statsd integration
  • Routes configuration 🚧
  • PII detection and masking 🚧

Getting Started

The easiest way to get started with BricksLLM is through BricksLLM-Docker.

Step 1 - Clone BricksLLM-Docker repository

git clone https://github.com/bricks-cloud/BricksLLM-Docker

Step 2 - Change to BricksLLM-Docker directory

cd BricksLLM-Docker

Step 3 - Deploy BricksLLM locally with Postgresql and Redis

docker-compose up

You can run this in detach mode use the -d flag: docker-compose up -d

Step 4 - Create a provider setting

curl -X PUT http://localhost:8001/api/provider-settings \
   -H "Content-Type: application/json" \
   -d '{
          "provider":"openai",
          "setting": {
             "apikey": "YOUR_OPENAI_KEY"
          }
      }'

Copy the id from the response.

Step 5 - Create a Bricks API key

Use id from the previous step as settingId to create a key with a rate limit of 2 req/min and a spend limit of 25 cents.

curl -X PUT http://localhost:8001/api/key-management/keys \
   -H "Content-Type: application/json" \
   -d '{
	      "name": "My Secret Key",
	      "key": "my-secret-key",
	      "tags": ["mykey"],
        "settingId": "ID_FROM_STEP_FOUR",
        "rateLimitOverTime": 2,
        "rateLimitUnit": "m",
        "costLimitInUsd": 0.25
      }'

Congradulations you are done!!!

Then, just redirect your requests to us and use OpenAI as you would normally. For example:

curl -X POST http://localhost:8002/api/providers/openai/v1/chat/completions \
   -H "Authorization: Bearer my-secret-key" \
   -H "Content-Type: application/json" \
   -d '{
          "model": "gpt-3.5-turbo",
          "messages": [
              {
                  "role": "system",
                  "content": "hi"
              }
          ]
      }'

Or if you're using an SDK, you could change its baseURL to point to us. For example:

// OpenAI Node SDK v4
import OpenAI from 'openai';

const openai = new OpenAI({
  apiKey: "some-secret-key", // key created earlier
  baseURL: "http://localhost:8002/api/providers/openai/v1", // redirect to us
});
