Phi-4 14B needs ~13.4 GB but RTX 2060 6GB only has 6.0 GB. Try a smaller quantization or lighter model.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 13.4 GB, but this setup only exposes 6.0 GB of usable VRAM.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.

No, Phi-4 14B requires more memory than RTX 2060 6GB provides.
Phi-4 14B (14B parameters) requires approximately 13.4 GB of memory with Q4_K_M quantization.
The recommended quantization for Phi-4 14B is Q4_K_M, which balances quality and memory efficiency.
On RTX 2060 6GB, Phi-4 14B achieves approximately 3.6 tokens per second decode speed with a time-to-first-token of 53536ms using Q4_K_M quantization.
For coding workloads, Phi-4 14B on RTX 2060 6GB receives a F grade with 3.6 tok/s and 4K context.
On RTX 2060 6GB, Phi-4 14B can safely use up to 4K tokens of context. The model's official context limit is 16K, but available memory constrains the safe maximum.
Add more VRAM headroom. The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
