Yes — with 10.6 GB to spare

Phi-4-mini 3.8B at Q4_K_M fits your GeForce RTX 4060 Ti 16 GB entirely on the GPU at 8K context, at an estimated 81 tokens per second. Past 93K the KV cache pushes it over — quantise the cache to q8_0, or step down a quantisation, to go longer.

Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it.
