open-gsio

Note

: I am porting logic from 3 projects back into this one. The styling is a work in progress and some functionality may be broken. Tests are being actively ported and stability will improve over time. Thank you for your patience.

This is a full-stack Conversational AI. It runs on Cloudflare or Bun.

Installation

1. bun i && bun test:all
2. Setup Local Inference OR Add your own GROQ_API_KEY in packages/cloudflare-workers/open-gsio/.dev.vars
3. In isolated shells, run bun run server:dev and bun run client:dev

Note: it should be possible to use pnpm in place of bun.

Deployment

1. Setup KV_STORAGE binding in packages/server/wrangler.jsonc
2. Add keys in secrets.json
3. Run bun run deploy && bun run deploy:secrets && bun run deploy

Note: Subsequent deployments should omit bun run deploy:secrets

Local Inference

Local inference is achieved by overriding the OPENAI_API_KEY and OPENAI_API_ENDPOINT environment variables. See below.

mlx-omni-server

(default) (Apple Silicon Only) - Use Ollama for other platforms.

# (prereq) install mlx-omni-server
brew tap seemueller-io/tap                   
brew install seemueller-io/tap/mlx-omni-server 

bun run openai:local mlx-omni-server         # Start mlx-omni-server
bun run openai:local:configure               # Configure connection
bun run server:dev                           # Restart server

Adding models for local inference (Apple Silicon)

# ensure mlx-omni-server is running

# See https://huggingface.co/mlx-community for available models
MODEL_TO_ADD=mlx-community/gemma-3-4b-it-8bit

curl http://localhost:10240/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d "{
    \"model\": \"$MODEL_TO_ADD\",
    \"messages\": [{\"role\": \"user\", \"content\": \"Hello\"}]
  }"

Ollama

bun run openai:local ollama                  # Start ollama server
bun run openai:local:configure               # Configure connection
bun run server:dev                           # Restart server

Adding models for local inference (ollama)

# See https://ollama.com/library for available models
use the ollama web ui @ http://localhost:8080

Testing

Tests are located in __tests__ directories next to the code they test. Testing is incomplete at this time.

bun test:all will run all tests

Troubleshooting

1. bun clean
2. bun i
3. bun server:dev
4. bun client:dev
5. Submit an issue
