Yes — with 7.1 GB to spare
Devstral Small 2 24B at Q4_K_M fits your RTX A5000 entirely on the GPU at 8K context, at an estimated 34 tokens per second. Past 53K the KV cache pushes it over — quantise the cache to q8_0, or step down a quantisation, to go longer.

Quantisation ladder
| Quant | Weights | Total @ 8K | Max context | Tok/s | Quality | Fit |
|---|---|---|---|---|---|---|
| Q8_0 | 23.7 GB | 25.6 GB | — | ~7.6 | −0.1% ppl | 3.2 GB over |
| Q6_K | 18.3 GB | 20.2 GB | 22K | 25 | −0.4% ppl | Long context |

Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it.
