Ollama Grid Search: Instantly Evaluate Multiple LLMs and Prompts.

This project automates the process of selecting the best models, prompts, or inference parameters for a given use-case, allowing you to iterate over their combinations and to visually inspect the results.

It assumes Ollama is installed and serving endpoints, either in localhost or in a remote server.

Here's what an experiment for a simple prompt, tested on 3 different models, looks like:

Installation

Check the releases page for the project, or on the sidebar.

Features

  • Automatically fetches models from local or remote Ollama servers;
  • Iterates over multiple different models, prompts and parameters to generate inferences;
  • A/B test different prompts on several models simultaneously;
  • Allows multiple iterations for each combination of parameters;
  • Allows limited concurrency or synchronous inference calls (to prevent spamming servers);
  • Optionally outputs inference parameters and response metadata (inference time, tokens and tokens/s);
  • Refetching of individual inference calls;
  • Model selection can be filtered by name;
  • List experiments which can be downloaded in JSON format;
  • Experiments can be inspected in readable views;
  • Re-run past experiments, cloning or modifying the parameters used in the past;
  • Configurable inference timeout;
  • Custom default parameters and system prompts can be defined in settings
  • Fully functional prompt database with examples;
  • Prompts can be selected and "autocompleted" by typing "/" in the inputs

Grid Search (or something similar...)

Technically, the term "grid search" refers to iterating over a series of different model hyperparams to optimize model performance, but that usually means parameters like batch_size, learning_rate, or number_of_epochs, more commonly used in training.

But the concept here is similar:

Lets define a selection of models, a prompt and some parameter combinations:

gridparams

The prompt will be submitted once for each parameter value, for each one of the selected models, generating a set of responses.

A/B Testing

Similarly, you can perform A/B tests by selecting different models and compare results for the same prompt/parameter combination, or test different prompts under similar configurations:

A/B testing

Comparing the results of different prompts for the same model

Prompt Archive

You can save and manage your prompts (we want to make prompts compatible with Open WebUI)

Settings

You can autocomplete prompts by typing "/" (inspired by Open WebUI, as well):

A/B testing

Experiment Logs

You can list, inspect, or download your experiments:

Future Features

  • Grading results and filtering by grade
  • Importing, exporting and sharing prompt lists and experiment files.

Contributing

  • For obvious bugs and spelling mistakes, please go ahead and submit a PR.

  • If you want to propose a new feature, change existing functionality, or propose anything more complex, please open an issue for discussion, before getting work done on a PR.

Development

  1. Make sure you have Rust installed.

  2. Clone the repository (or a fork)

git clone https://github.com/dezoito/ollama-grid-search.git
cd ollama-grid-search

  1. Install the frontend dependencies.

    cd <project root>
# I'm using bun to manage dependencies,
# but feel free to use yarn or npm
bun install

  2. Make sure rust-analyzer is configured to run Clippy when checking code.

    If you are running VS Code, add this to your settings.json file

    {
   ...
   "rust-analyzer.check.command": "clippy",
}

    (or, better yet, just use the settings file provided with the code)

  3. Run the app in development mode

    cd <project root>/
bun tauri dev

  4. Go grab a cup of coffee because this may take a while.
