WizardLM 13B needs ~22.9 GB but RTX 5060 Ti 16GB only has 16.0 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.

Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 22.9 GB, but this setup only exposes 16.0 GB of usable VRAM.
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, WizardLM 13B requires more memory than RTX 5060 Ti 16GB provides.
WizardLM 13B (13B parameters) requires approximately 22.9 GB of memory with Q4_K_M quantization.
The recommended quantization for WizardLM 13B is Q4_K_M, which balances quality and memory efficiency.
On RTX 5060 Ti 16GB, WizardLM 13B achieves approximately 12.8 tokens per second decode speed with a time-to-first-token of 15070ms using Q4_K_M quantization.
For coding workloads, WizardLM 13B on RTX 5060 Ti 16GB receives a F grade with 12.8 tok/s and 7K context.
On RTX 5060 Ti 16GB, WizardLM 13B can safely use up to 7K tokens of context. The model's official context limit is 8K, 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.
