Show HN: Cactus Needle 3: 8-29MB automation models can match DeepSeek V4 Flash

Cactus Needle 3 introduces automation models ranging from 8-29MB, capable of matching DeepSeek V4 Flash. These models feature an "intelligence ladder" design, where a single set of weights supports various depths from 2 to 20 layers. Subnetworks as small as 2 layers can be fine-tuned for specific tasks, achieving frontier-level accuracy on devices smaller than the full model. Fine-tuning on DroidCall, for instance, improves every subnetwork by 18 to 36 points, with 4-layer subnetworks and above surpassing DeepSeek V4 Flash, starting at 29M parameters.
