# Changelog: 2025-01-31

## Highlights

* \[New Feature] **Managed Checkpoints**: Simplify and accelerate your AI training workflows with secure, scalable, and reusable snapshots of model states.
* \[New Feature] **Live Checkpoint Capture**: List checkpoints from an in-progress or completed Training Job and reuse it for evaluation or further fine-tuning without waiting for downloads or uploads.
* \[Improved UX] **Training Logs and Output Handling**: Training logs now clearly indicate their start and end, and outputs retain directory structures when fetched.

## Added

* **Managed Checkpoints:** Manage checkpoints using the [`flexai checkpoint`](/cli/reference/checkpoint) command checkpoints to list, upload, download, and export them. List checkpoints from an in-progress or completed Training Job and reuse it for evaluation or resume the training using the `--checkpoint <checkpoint_name_or_UID>` flag without any manual data transfer.
* **Fine-Tuning:** Bring pre-trained models into FCS from a local machine or remote storage (e.g. AWS) once and reuse them for any of your fine-tuning workloads, saving on egress fees and transfer times.
* **Inspect checkpoints:** View detailed checkpoint information, including creation time and metadata, using `checkpoint inspect`.
* **Check for updates**: Use the `doctor` command to check for CLI updates and stay up-to-date with the latest features.
* **Multi-GPU Interactive Training**: Enhanced Interactive Training with support for multi-GPU single-node setups. Use `flexai training debug-ssh --accels <1 to 8>` for debug and optimization of distributed workloads.

## Changed

* **Sorted Checkpoint List**: The `training checkpoints` or `checkpoint list` sorts checkpoints by creation time in ascending order, making it easier to locate relevant checkpoints.

* **Directory Retention**: Outputs fetched from Training Jobs or checkpoints maintain their original directory structure, simplifying file management.

* **Improved Help Text**: Help messages for `push` commands provide clearer guidance.

* **Improved Training flow UX**: Improved the `training run` output message to suggest the command to run to monitor its log output.

  ```bash theme={null}
  flexai training run mistral_ft_34 ...

  Training job mistral_ft_34.
  Use 'flexai training logs mistral_ft_34' to follow the progress of your Training Job.
  ```

* **Clear Logs Start**: `training logs` clearly indicate the start point of the logs stream.

## Fixed

* **Logs Termination UX**: The logs stream from `training logs` terminates at the end of the Training Job.
* **Relative Path Uploads**: Fixed failures with path resolutions for dataset and checkpoint uploads.
