Model Detail

MemPrivacy-4B-RL is a large language model with 4B parameters released by IAAR-Shanghai. The model is registered under the text-generation pipeline tag on Hugging Face, distributed under the permissive cc-by-nc-nd-4.0 license.

MemPrivacy-4B-RL ships with 4B parameters. Total weight footprint is approximately 4.0 GB, which is the relevant figure when planning local-inference VRAM. The cc-by-nc-nd-4.0 license is permissive, allowing commercial deployment and derivative work without per-seat fees, though attribution requirements still apply.

MemPrivacy-4B-RL is best fit for general-purpose chat and instruction-following workloads. Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.
