Decision models (Clef, pplx-decider, d3, H2O-Lightning, d1…) each ship their own runtime: custom PyTorch code, a vLLM shim, CUDA assumptions. mlx-decision runs all of them on Apple Silicon with #MLX, behind one API. 🧵

Fine-tuning on the Mac: mlx-decision data turns a HF dataset or CSV into labelled examples, training fit fits in minutes, and training eval --compare scores the result against its base. d1-3B on TREC: 86.6% → 96.4% in 4 min (M5 Pro).

And a local web app (mlx-decision web) to compare models side by side and score datasets with accuracy, a confusion matrix and calibration. Everything it writes is a plain file the CLI reads. pip install mlx-decision github.com/armbues/mlx-decis…

Running Llama-3-8B-Instruct on Mac with the SiLLM framework powered by MLX... just took some fiddling with the tokenizer & template to get it to run 😁

A huge thank you to @awnihannun @angeloskath and the rest of the team for developing the MLX framework that SiLLM relies on! Also big kudos to all the contributors of the MLX Examples project 👏

One of the reasons to attend the #CARO2023 is the food for thought that is delivered in talks, conversations, and of course keynotes. Armin Büscher @armbues will share his technical perspective about innovation and disruption in cybersecurity. caro2023.org/#c228106

This file leaked an Security Enterprise Virustotal API Key before!But now it's expired because someone leaked the key😅 ITW:07c4a75b1422a22ec29c5102e0b67055 API Key:d10468bead05da1685629a0abcfed5f963d6adbc7e6bb2b2fc343dbb36be0349 unbelievable!

I'll be traveling to Vegas for #blackhat2022 and #DEFCON next week. Looking forward to hang out with many infosec folks I haven't seen in a long time 🥳
