Makes the model fit on the accelerator instead of staying completely out of reach.
Raises estimated decode speed by about 168%.

Codestral 22B needs ~17.6 GB but RX 5700 XT 8GB only has 8.0 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 17.6 GB, but this setup only exposes 8.0 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, Codestral 22B requires more memory than RX 5700 XT 8GB provides.
Codestral 22B (22B parameters) requires approximately 17.6 GB of memory with Q4_K_M quantization.
The recommended quantization for Codestral 22B is Q4_K_M, which balances quality and memory efficiency.
On RX 5700 XT 8GB, Codestral 22B achieves approximately 2.8 tokens per second decode speed with a time-to-first-token of 69163ms using Q4_K_M quantization.
For coding workloads, Codestral 22B on RX 5700 XT 8GB receives a F grade with 2.8 tok/s and 4K context.
On RX 5700 XT 8GB, Codestral 22B can safely use up to 4K tokens of context. The model's official context limit is 33K, 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.
