MPT-30B-Instruct needs ~49.4 GB but RTX PRO 4500 Blackwell 32GB only has 32.0 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 49.4 GB, but this setup only exposes 32.0 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-30B-Instruct requires more memory than RTX PRO 4500 Blackwell 32GB provides.
MPT-30B-Instruct (30B parameters) requires approximately 49.4 GB of memory with Q5_K_M quantization.
The recommended quantization for MPT-30B-Instruct is Q5_K_M, which balances quality and memory efficiency.
On RTX PRO 4500 Blackwell 32GB, MPT-30B-Instruct achieves approximately 11.2 tokens per second decode speed with a time-to-first-token of 17300ms using Q5_K_M quantization.
For coding workloads, MPT-30B-Instruct on RTX PRO 4500 Blackwell 32GB receives a F grade with 11.2 tok/s and 4K context.
On RTX PRO 4500 Blackwell 32GB, MPT-30B-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.
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.
