MPT-30B-Instruct needs ~49.4 GB but Radeon Pro W7800 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.

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.

Inference speed
Estimated decode speed (tokens/sec) for MPT-30B-Instruct at Q5_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is MacBook Pro M4 Max 128GB at ~28 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

No, MPT-30B-Instruct requires more memory than Radeon Pro W7800 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 Radeon Pro W7800 32GB, MPT-30B-Instruct achieves approximately 4.8 tokens per second decode speed with a time-to-first-token of 40186ms using Q5_K_M quantization.
For coding workloads, MPT-30B-Instruct on Radeon Pro W7800 32GB receives a F grade with 4.8 tok/s and 4K context.
On Radeon Pro W7800 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.
