Quickstart

Train a model on your own data in a few steps. Everything here runs in your self-service workspace.

Before you start

  • A dataset in JSONL format, up to 50 MB. See Preparing your dataset.
  • A card to add to your workspace. Training is billed by verified usage; the card pays any amount above your credits.
  • Rights to use the data for training. You confirm this before every run.

1. Create your workspace

Go to Try Self-Service and sign up with your email, then confirm your address from the email we send and log in. Or choose Continue with Google to sign up or log in with your Google account; no confirmation email is needed. Either way, team invitations go to an email address, so use the account with the invited email. Your workspace opens on the Overview page.

2. Add a card and credits

  1. Open Billing and choose Add a card. You enter the card and billing address on our payment processor's secure page; we store only the brand, last four digits and expiry.
  2. Choose Add credits and enter any amount of at least $1. Credits appear once the payment is confirmed.

3. Upload a dataset

Open Datasets and upload your .jsonl file. We check every row; if a row is invalid, the upload stops and tells you which row and why. A ready dataset shows its row count.

4. Set up training

  1. Open Training and choose New training run, or pick Fine-tune next to a model on the Models page.
  2. Choose a base model, your dataset and a job name. The method is supervised fine-tuning (SFT).
  3. Adjust epochs and other settings if you need to. See Training settings.
  4. Confirm you have the rights to use the data. A live cost estimate appears in the sidebar.

5. Review and start

Choose Review training job. A confirmation shows the model, epochs, estimate and the amount held while training (the estimate plus 25%). Tick the consent box and confirm to start. The hold is not a charge: you pay only the verified cost once training finishes.

The estimate is a planning figure, not the charge. You pay the verified cost of your run, which can be higher or lower. See Billing and credits.

6. Follow the run

Your run appears under Training with its progress. When training ends, the run shows Trained and its charge appears under Billing once verified. Your monthly spend appears under Usage.

If a run fails before training starts, it ends as failed and you are not charged.
