This setup is broadly balanced for this model.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Inference speed
Estimated decode speed (tokens/sec) for MPT-7B-Instruct at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~98 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.

Yes, NVIDIA A2 16GB can run MPT-7B-Instruct with a B grade (Tight fit). Expected decode speed: 36.5 tok/s.
MPT-7B-Instruct (7B parameters) requires approximately 14.9 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 NVIDIA A2 16GB, MPT-7B-Instruct achieves approximately 36.5 tokens per second decode speed with a time-to-first-token of 5299ms using Q4_K_M quantization.
For coding workloads, MPT-7B-Instruct on NVIDIA A2 16GB receives a B grade with 36.5 tok/s and 8K context.
On NVIDIA A2 16GB, MPT-7B-Instruct can safely use up to 8K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
Buy headroom, not only minimum fit. A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
