Yi Coder 9B Chat — Hardware Requirements & GPU Compatibility

ChatCode

Yi-Coder 9B Chat is 01.AI's 9-billion-parameter instruction-tuned model for code, built upon the Yi-Coder-9B base checkpoint. The card claims support for 52 programming languages and lists a 23% pass rate on LiveCodeBench; it notes this is the only model under 10 billion parameters to hit 20%. Its focus is coding assistance, code completion, and long-file understanding instead of general chat. At this size, quantization lets it run on a single consumer GPU, and even mid-range cards handle a 4-bit build. The model handles a 131,072 token context window, sufficient for large source files or multiple ones at once. Released under the Apache 2.0 license, it allows unrestricted commercial and research use. Published in August 2024, it joins a 1.5B chat model and base versions of both sizes within the series.

Frequently Asked Questions

How much VRAM does Yi Coder 9B Chat need?

Yi Coder 9B Chat requires 5.8 GB of VRAM at Q4_K_M, or 18.2 GB at BF16. Full 131K context adds up to 12.7 GB (18.5 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 8.8B × 4.8 bits ÷ 8 = 5.3 GB

KV Cache + Overhead ≈ 0.5 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 ≈ 13.2 GB (at full 131K context)
