macOS app to chat with local foundation models. Ollama is well-supported, and .gguf files are loaded via llama-cpp-python (put/symlink them in ~/Library/Application Support/faux.brokegen/).
Key differentiator is a focus on data capture and retention; text and inference stats are stored in SQLite databases, which also makes it easy to import data from external sources.

• Virtually all settings are overrideable (model template, system prompt, start of assistant response, ollama/llama.cpp inference options)
• Chats can be branched at any point, and inference models re-selected at any point
• Ollama proxy is built-in, so any messages sent through other apps will be captured and show up in brokegen (only /api/chat requests, not /api/generate). When the server is started, the proxy is available on http://localhost:6635/ollama-proxy.

Minor features:

• Chats are optionally auto-named by the UI (the naming prompts in the app work best with llama3 models)
• Overridden prompts/templates are stored in a SwiftData store, while broad settings like "render as markdown" are stored using @AppStorage
• User/assistant messages can be sent in any order (continue assistant inference even during its turn + keep "saving" user messages without inference), though this depends on the model template + whether the model handles out-of-turn events well.

Tested and developed on macOS 14.2+, M1 MBP + 2019 Intel MBP. Pre-built binaries are x86 only, compiled for AVX2 CPU's and will run inference very slowly (estimated 3-6 tokens/sec for ollama's mistral-7b, but this seems to be limited by memory bandwidth).

If you don't need to run custom models, install Ollama and use that as the inference provider:

1. Download from https://ollama.ai and open the application.
2. Once the command-line utility is installed, open a terminal and run ollama pull <MODEL_NAME>. The full list is available at https://ollama.ai/library.
3. Once the model has finished downloading, you can start using it.

Or, if you would rather use the embedded ollama binary, you can run a command like ./Brokegen.app/Contents/Resources/ollama-darwin pull mistral:7b, and use that for inference.

UI code is kept simpler, a lot of complexity is pulled in through the built-in Python server.

Python code is built with pyinstaller, and run as a service by the SwiftUI app. An embedded copy of ollama is also included, though you'll have to download models yourself.

• There is some support for reading langchain/FAISS vector stores, but the write code hasn't been added yet. RAG infrastructure is largely there, but I'd prefer to add a DSPy-centered implementation.
• For newer models like mistral-nemo and llama3.1, scaling the context up to 128k generally consumes more than 64 GB of RAM, so default context size is 512 tokens + user is expected to override these in the UI inference options.
• The llama-cpp-python provider defaults to CPU inference, which will be significantly slower on Apple Silicon Macs. Override this in inference options ({"n_gpu_layers": -1}), or use Ollama.
• Multi-modal support is non-existent; the /ollama-proxy endpoint supports forwarding image files to any ollama model that indicates support for it (e.g. llava), but image data will not be captured or replayable.
