I uploaded my dataset for instance segmentation and tried to run a custom training, but SAM3 does not appear as an option. Could you tell me what might be causing this issue? ---

Hi @Jaeyoung Unfortunately, for trial and core plan users. SAM3 fine tuning is unavailable. We still have SAM3 in workflows and inference available for you! If you are looking to complete a segmentation project I would highly recommend checking out RF-DETR segment as a well rounded alternative to SAM3. ---
