Yi 34B Chat — Hardware Requirements & GPU Compatibility
ChatYi-34B-Chat is 01.AI's instruction-tuned chat model built on the 34-billion-parameter Yi-34B base, a bilingual English/Chinese model trained from scratch on roughly 3 trillion tokens. At launch in late 2023 it placed second only to GPT-4 Turbo on the AlpacaEval leaderboard among a field that included GPT-4, Mixtral, and Claude, an unusually strong result for an open bilingual model of its generation. Running the full-precision checkpoint needs a multi-GPU workstation or a single high-end data-center card, but the official 4-bit quantized release fits a single consumer GPU. A separate Yi-34B-200K sibling extends the same base model's context far beyond this chat version. Context length is 4,096 tokens. It is released under the Apache 2.0 license, permitting unrestricted commercial and research use, and was published in November 2023, making it one of the earlier open 34B-class chat models rather than a current-generation release.

Frequently Asked Questions
How much VRAM does Yi 34B Chat need?
Yi 34B Chat requires 21.4 GB of VRAM at Q4_K_M, or 69.6 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 34.4B × 4.8 bits ÷ 8 = 20.6 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.
KV Cache + Overhead ≈ 1.3 GB (at full 4K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Yi 34B Chat?
Yes, at Q5_0 (22.3 GB) or lower. Higher quantizations like Q5_K_S (24.4 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Yi 34B Chat?
For Yi 34B Chat, Q4_K_M (21.4 GB) offers the best balance of quality and VRAM usage. Q5_0 (22.3 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 10.3 GB.
