Home Assistant Specialist v0.4 — Qwen3-4B Q5_K_M

GGUF artifact for local Ollama inference.

File: Qwen3-4B-Instruct-2507.Q5_K_M.gguf

Quantization: Q5_K_M

Task: strict ha-action-v3 Home Assistant JSON planning.

Dataset provenance: V4 combines validated rows from acon96/Home-Assistant-Requests, acon96/Home-Assistant-Requests-V2, and project-curated contract cases. See the V4 dataset card for counts and filtering details.

Benchmark
