MPT-7B-Instruct needs ~14.1 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 14.1 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, MPT-7B-Instruct requires more memory than RTX 4060 Ti 8GB provides.
MPT-7B-Instruct (7B parameters) requires approximately 14.1 GB of memory with Q4_K_M quantization.
The recommended quantization for MPT-7B-Instruct is Q4_K_M, which balances quality and memory efficiency.
On RTX 4060 Ti 8GB, MPT-7B-Instruct achieves approximately 11.2 tokens per second decode speed with a time-to-first-token of 17239ms using Q4_K_M quantization.
For coding workloads, MPT-7B-Instruct on RTX 4060 Ti 8GB receives a F grade with 11.2 tok/s and 4K context.
On RTX 4060 Ti 8GB, MPT-7B-Instruct can safely use up to 4K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
