Changelog

Added

  • Evaluation

    • Edit the settings of an evaluation and rerun it, in the evaluation panel or the API.
    • Delete an evaluation in the evaluation panel or the API. Annotations stay unchanged, and filters that use the evaluation are removed.

  • Filtering

    • Filter by metadata in the query editor, e.g. metadata["score"] >= 0.8.
    • Python SDK: Filter images and videos by metadata, including nested fields, e.g. ImageSampleField.metadata["odometry.speed"] < 15.
    • Filter captions by tag and metadata in the captions tab.
    • Reset all filters with one click with the new "Clear all filters" button.

  • Annotations

    • Copy an annotation to another annotation source in the details view, or create a new source while you copy.
    • Set your own keyboard shortcut for AI-assisted labeling in the settings.

  • Other

    • Get started quickly with a short onboarding tour on image datasets.
    • See why a button is disabled in its tooltip.
    • Show sharp pixel edges when you zoom into images with the new image interpolation setting.
    • Python SDK: Embed video frames on a remote embedding server registered with register_default_embedder.
    • Python SDK: Report anonymous usage data on how data is loaded (format and source). Set LIGHTLY_STUDIO_ANALYTICS_ENABLED=false to opt out.

Changed

  • Tags

    • BREAKING: A tag now holds only samples of its own collection, and tags no longer have a kind field. PostgreSQL migrates automatically. DuckDB users must re-index their data before they create tags.
    • Adding many samples to a tag is faster.

  • Embeddings

    • BREAKING: Python SDK: Image search in the GUI now needs an embedder that implements ImageBytesEmbedder. Implement it in your custom embedder to keep image search.
    • Python SDK: New video datasets embed frames with Perception Encoder (PE-Core-T16-384) instead of MobileCLIP. Existing datasets are not changed.
    • Python SDK: Crops and frames are embedded automatically with a previously used compatible remote embedder.

  • Embedding plot

    • Set the text axes with the new "Define axes" button. The applied texts show at the plot edges, and "Reset axes" returns to PaCMAP.
    • Text axes are now balanced and comparable. Lines at x = 0 and y = 0 split the plot into four parts, and axes with weak text matches now look small.
    • Points that are filtered out or have no category are easier to see on dark backgrounds.

  • Evaluation

    • The evaluation panel has clearer settings and confusion matrix filters. Sorts are grouped by metric, show the highest counts first, and mark missing results.
    • Python SDK: dataset.evaluate() and evaluation recompute are faster on large datasets.

  • Other

    • Python SDK: start_gui() opens the browser. Pass open_browser=False, or use lightly-studio gui --no-browser, to turn this off.

Fixed

  • Annotations

    • Annotation cards stay aligned, source colors stay stable, and confidence stays visible when you hide annotations or switch to editing.
    • Deleting annotations now also deletes their captions.

  • Evaluation

    • Evaluation results are kept when a recompute fails.

  • Other

    • The grids return to the exact scroll position when you go back from the details view.
    • Python SDK: start_gui() stops cleanly on Ctrl+C, without a traceback.
    • The GUI footer no longer shows a dev commit hash for released versions.
