OPAL

OPAL is a PyTorch optimizer wrapper that lets a coding agent rewrite optimizer and analysis programs while a model trains. It runs in the training process and supports agent-free dry runs with the `keep` backend.

What it does

A person can use OPAL to experiment with agent-adjusted optimizers during PyTorch training runs.

Availability
Install with `pip install opal-optimizer`; source and guide are on GitHub
Pricing model
Agent usage is billed to the Claude subscription or API key; `max_cost_usd` can cap spending
Deployment
Runs inside the training process on CPU, one GPU, or multiple GPUs of one node (DDP)
Privacy
The agent can see the goal, parameter names and shapes, losses, analysis reports, and read-only training script and model code; `share_code=False` keeps code out

Evidence

5 claims
  • OPAL lets a coding agent rewrite optimizer and analysis programs during a training run. [1]
    rewrite two small programs: the optimizer program, which turns gradients into updates at every step, and an analysis

    The package is called `opal-optimizer` on PyPI, because `opal` there is an unrelated web framework.

  • Agent usage is billed to the Claude subscription or API key, and there is no cost cap by default. [1]
  • The agent can receive read-only copies of the training script and model code; `share_code=False` keeps them out. [1]
