It depends on your usecase and the size of your ram is not the only driver. I think the primary performance drivers (without sacrificing precision) right now are QAT, MTP/DFlash, MoE and Hybrid approaches to avoid full attention in parts by replacing with linear / sparse attention. So Gemma4 26B A4B QAT+MTP (from unsloth) would be a good pick atm. I'd love to see some smaller models with all that features.
