StableLM 2 12B needs ~22.5 GB but RTX 4060 Ti 8GB only has 8.0 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 22.5 GB, but this setup only exposes 8.0 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, StableLM 2 12B requires more memory than RTX 4060 Ti 8GB provides.
StableLM 2 12B (12B parameters) requires approximately 22.5 GB of memory with Q5_K_M quantization.
The recommended quantization for StableLM 2 12B is Q5_K_M, which balances quality and memory efficiency.
On RTX 4060 Ti 8GB, StableLM 2 12B achieves approximately 3.6 tokens per second decode speed with a time-to-first-token of 54149ms using Q5_K_M quantization.
For coding workloads, StableLM 2 12B on RTX 4060 Ti 8GB receives a F grade with 3.6 tok/s and 4K context.
On RTX 4060 Ti 8GB, StableLM 2 12B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.
