DEIM

We don't benchmark DEIM.

It is an open-weight model from Intellindust AI Lab under the Apache 2.0 license, and free for commercial use.

DEIM Overview

DEIM is a training framework for DETR-based object detection models released in December 2024 by researchers at Intellindust AI Lab, City University of Hong Kong, Great Bay University, and Hefei Normal University. It enhances existing real-time DETR architectures by improving the matcher used during training, enabling faster convergence and higher accuracy without modifying the inference architecture or adding computational overhead at deployment time. DEIM introduces two core techniques: Dense One-to-One (O2O) matching, which increases the number of positive matches per target, and Matchability-Aware Loss (MAL), which down-weights low-quality matches generated by the dense strategy. The paper was accepted at CVPR 2025.

DEIM License

Apache-2.0 · Permissive license

DEIM is released under the Apache 2.0 license, so it's commercially usable out of the box: you can ship it in closed-source, commercial products, including self-hosted deployments, without paying a license fee or open-sourcing your code. The DEIM license is permissive, so no separate commercial license is required.

Commercial use: Permitted. Because Apache-2.0 is permissive, DEIM can ship inside paid products and internal systems with no commercial license and no revenue threshold.
Modification: Permitted. Fine-tuning, quantizing, and distilling are all allowed, and your code changes can stay closed. Files you change must be marked as changed.
Redistribution: Permitted with attribution. Ship the Apache-2.0 license text and any NOTICE file alongside the weights or derived code.

Apache-2.0 grants an express patent license that terminates if you bring a patent claim over the work, and it disclaims warranties. Validate DEIM on your own data before you depend on it in production.
