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
- Licence
- Not established
