Introducing Ponder Training.

Build your own models.

An experimental lab for model training and weight modifications. Run SFT and RL, train LoRA adapters, and build continual-learning loops with our harness or your own.

iOS app

Model modifications

Train weights, edit knowledge, or work with activations. Explore how each method changes a model.

SFT

Continual learning

Train a LoRA adapter on reviewed answers while keeping base weights frozen.

Reviewed examplesInputs and approved answers

ExampleTeach a support model to return your response format from reviewed conversations.

Ponder Training

Train, evaluate and improve a model from the same experiment setup.

SFTContinual learning
Supervised fine-tuning teaches the model from reviewed examples. Save a trained adapter.
RLContinual learning
Reinforcement learning with GRPO scores groups of responses and learns from the rewards.
Continual learning
Schedule reviewed SFT batches or compatible GRPO updates, with review, spending limits and independent evaluation.

Continual learning

Keep learning from the work your agents already do. Bring in new tasks, add feedback, and measure whether each update makes your model better.

Bring in new tasks

Conversation logs
Connect your agents and choose which conversations to import.
Your harness
Send tasks and results through the OpenPond CLI or SDK.
Fix-it AgentBeta
Collect supported tool failures and recovery evidence for review.
Manual tasks
Add examples yourself, or import a dataset you already have.
Set up continual learning

OpenPond Desktop & Harness

Work with agents beside your local projects, then turn a dataset into an evaluation plan without leaving the app.
