Ultralytics v8.4.24 is out :tada:

Quick summary: Ultralytics v8.4.24 improves training reliability on the Ultralytics Platform :rocket:, updates tuning defaults to better match Ultralytics YOLO26 best practices :bullseye:, refreshes docs and benchmarks, and adds safer guardrails around TF.js benchmarking.

This release is all about making training workflows clearer, tuning more effective, and the overall experience more consistent across product, docs, and tooling.

:glowing_star: Highlights

Better Platform training error surfacing :hammer_and_wrench:

The biggest improvement in v8.4.24 is clearer error handling for Platform training sessions.

Users will now see the actual server-side error message when available, instead of a generic HTTP response. If a training session fails to register, the message is now much clearer:

Training will not be tracked on Platform

To keep logs clean and avoid repeated follow-up warnings, Platform callbacks are also disabled after registration failure.

This means:

  • Faster troubleshooting :white_check_mark:
  • Less noisy logs :white_check_mark:
  • A smoother fallback experience :white_check_mark:

Ray Tune search space updated for YOLO26 :chart_increasing:

We’ve aligned the Ray Tune search space and examples with modern YOLO26 tuning ranges, including updates to parameters like:

  • lr0
  • momentum
  • box
  • cls
  • scale

We also added missing parameters such as:

  • dfl
  • close_mosaic

These updates help users tune with more realistic defaults and avoid outdated search spaces that can hurt results.

YOLO26 naming adopted in the Streamlit selector :counterclockwise_arrows_button:

The Streamlit inference UI now uses yolo26* model options instead of yolo11*, bringing the experience in line with the latest recommended model family.

Rockchip RKNN docs refreshed :blue_book:

RKNN benchmark tables were updated to reflect YOLO26 models and newer tested package versions, making deployment guidance more current and useful.

TF.js benchmarking temporarily disabled :warning:

To prevent confusing runtime failures caused by a known protobuf dependency conflict, TF.js export benchmarking has been temporarily blocked as a safeguard.

Improvements

Docs and UX polish :receipt:

This release also includes several documentation and interface improvements:

  • Clearer Platform plan and GPU tier messaging
  • Added real screenshots to important Platform docs pages
  • Formatting and content cleanup across docs
  • Small UI and reference page polish
