Yi 34B Chat needs ~26.9 GB but RX 6950 XT 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.
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 26.9 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, Yi 34B Chat requires more memory than RX 6950 XT 16GB provides.
Yi 34B Chat (34B parameters) requires approximately 26.9 GB of memory with Q4_K_M quantization.
The recommended quantization for Yi 34B Chat is Q4_K_M, which balances quality and memory efficiency.
On RX 6950 XT 16GB, Yi 34B Chat achieves approximately 4.4 tokens per second decode speed with a time-to-first-token of 44067ms using Q4_K_M quantization.
For coding workloads, Yi 34B Chat on RX 6950 XT 16GB receives a F grade with 4.4 tok/s and 4K context.
On RX 6950 XT 16GB, Yi 34B Chat can safely use up to 4K tokens of context. The model's official context limit is 200K, 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.
