Yi 34B Chat — Hardware Requirements & GPU Compatibility

Chat

Yi-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)
