Pestle-27B-Ternary

Pestle-27B-Ternary is a compact 27B ternary-weight language model (8.48 GB GGUF) for local inference, packing private medical QA, biomedical evidence, pharmaceutical retrieval, coding, and general assistance into one runnable file under the Mortar runtime — a research preview, not a medical device.

★★★★⯨ 4.35 Free (Open Weights, Apache-2.0)

Pros / Advantages

  • 27B-class model compressed to a single 8.48 GB GGUF via ternary weights (-1/0/+1)
  • Strong medical benchmarks: MedQA 89.79, MedMCQA 68.85, PubMedQA 76.70 accuracy
  • Runs locally with Mortar (llama.cpp-compatible) on Apple Silicon, NVIDIA CUDA, or CPU
  • General capability retained: MMLU-Redux 83.53, GSM8K 93.25, HumanEval+ 87.20
  • Up to 262K context; optional vision input via a separate mmproj projection file

Cons / Limitations

  • Research preview only — explicitly not for clinical/diagnostic use
  • Requires building/running the separate Mortar runtime (no one-click hosted endpoint)
  • Based on Qwen3.6-27B; compression trades some accuracy vs full-precision FP16

ModelMap

3.8

ModelMap (modelmap.tech) is an interactive 3D visualization that turns AI model benchmark scores into explorable shapes. Each model's performance across public benchmarks is rendered as a 'spiky' 3D form — longer spikes mean higher scores — parsed live from Hugging Face model cards. Built on an open-source '3D Graph' library, it offers a flight-simulator-style interface (WASD to fly, mouse to look, click a spike to zoom, hover for tooltips) for browsing model data in space rather than static tables. A hidden Star Wars-themed mini-game underscores its goal of making model analysis more playful. It's a free, browser-based research toy — novel for building intuition, though it has drawn technical criticism on how it represents scores.
