No. Phi-4 14B does not fit on M3 8GB: Q4_K_M needs 10.4 GB and 5.4 GB is usable.
Hardware: M3 8GB · Model: Phi-4 14B
M3 8GB has 8 GB of unified memory and 100 GB/s of memory bandwidth. M2 8GB has the same memory and bandwidth, so the fit numbers match; this page is M3 8GB. The checker leaves macOS a share of unified memory, so Ollama can use 5.4 GB. Phi-4 14B (14.7B, Microsoft) at Q4_K_M is a 9.1 GB download and needs 10.4 GB with headroom for about 8k tokens.
