- Project mention: Why DETRs are replacing YOLOs for real-time object detection | news.ycombinator.com | 2025-11-22
> The YOLO series is developed and maintained by Ultralytics. All YOLO code and weights are released under the AGPL-3.0 license.The YOLO series is developed and maintained by Ultralytics. All YOLO code and weights are released under the AGPL-3.0 license.
The original author of YOLO and the Darknet framework [1] issued the code under pretty much every license you wish to use [2]. My preferred fork by AlexeyAB is under an equally permissive license [3].
Ultralytics then created their own model under the AGPL-3.0 license [4], which probably would never stand up in a court as they have the model from the likes of YOLOv3 in their source [5].
This entire article is flawed anyway, because they don't state which YOLOv11 model they are using or compare the accuracy. They appear to have just taken the pre-trained models and assumed it's apples-to-apples. They could have at least compared YOLO11n/s/m/l/x,

InternVL
[CVPR 2024 Oral] InternVL Family: A Pioneering Open-Source Alternative to GPT-4o. 接近GPT-4o表现的开源多模态对话模型
Project mention: InternVL3: Unified Multimodal AI Training Outperforms Open-Source Rivals | dev.to | 2025-04-17InternVL3 marks a significant advancement in the InternVL model series, implementing a native multimodal pre-training approach that fundamentally transforms how vision-language models learn. Unlike most leading multimodal large language models (MLLMs) that adapt text-only models to handle visual inputs through complex post-hoc alignment, InternVL3 jointly acquires multimodal and linguistic capabilities in a single unified pre-training stage.

autodistill
Images to inference with no labeling (use foundation models to train supervised models).
We (Roboflow) have had early access to this model for the past few weeks. It's really, really good. This feels like a seminal moment for computer vision. I think there's a real possibility this launch goes down in history as "the GPT Moment" for vision.
The two areas I think this model is going to be transformative in the immediate term are for rapid prototyping and distillation.
Two years ago we released autodistill[1], an open source framework that uses large foundation models to create training data for training small realtime models. I'm convinced the idea was right, but too early; there wasn't a big model good enough to be worth distilling from back then. SAM3 is finally that model (and will be available in Autodistill today).
We are also taking a big bet on SAM3 and have built it into Roboflow as an integral part of the entire build and deploy pipeline[2], including a brand new product called Rapid[3], which reimagines the computer vision pipeline in a SAM3 world. It feels really magical to go from an unlabeled video to a fine-tuned realtime segmentation model with minimal human intervention in just a few minutes (and we rushed the release of our new SOTA realtime segmentation model[4] last week because it's the perfect lightweight complement to the large & powerful SAM3).
We also have a playground[5] up where you can play with the model and compare it to other VLMs.
