MPT-30B-Instruct needs ~47.8 GB but RX 9070 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 47.8 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, MPT-30B-Instruct requires more memory than RX 9070 16GB provides.
MPT-30B-Instruct (30B parameters) requires approximately 47.8 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 RX 9070 16GB, MPT-30B-Instruct achieves approximately 2.8 tokens per second decode speed with a time-to-first-token of 68880ms using Q5_K_M quantization.
For coding workloads, MPT-30B-Instruct on RX 9070 16GB receives a F grade with 2.8 tok/s and 4K context.
On RX 9070 16GB, 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.
