Baichuan2 13B Chat — Hardware Requirements & GPU Compatibility
Chat
Baichuan2-13B-Chat is Baichuan Intelligence's 13-billion-parameter bilingual (Chinese/English) chat model, instruction-aligned from the Baichuan2-13B-Base model that was pretrained from scratch on 2.6 trillion tokens. It was evaluated across general, legal, medical, math, code, and multilingual-translation benchmarks against contemporaries like LLaMA2-13B-Chat and Vicuna-13B, and a 4-bit quantized version is also distributed for lower-memory deployment. At 13B parameters it needs a capable consumer GPU at full precision, considerably less once quantized to 4 bits. License is a custom Baichuan2 Community License: free for academic research, and free for commercial use after obtaining a license via email request to the developers. It was published in August 2023, with a v2 revision issued in December 2023 that improved math, logical reasoning, and instruction-following.

Frequently Asked Questions
How much VRAM does Baichuan2 13B Chat need?
Baichuan2 13B Chat requires 8.6 GB of VRAM at Q4_K_M, or 28.6 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 13B × 4.8 bits ÷ 8 = 7.8 GB
KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Baichuan2 13B Chat?
