Kimi-VL-A3B-Thinking-2506-W8A16

INT8 post-training quantization of moonshotai/Kimi-VL-A3B-Thinking-2506 — a 16B MoE vision-language model with thinking/reasoning. Language-model Linear layers quantized W8A16; vision tower and merger kept BF16.

Quick Start

Tested with vLLM v0.21.0. Weights are in compressed-tensors format — vLLM detects quantization automatically.

About

88plug AI Lab ships compressed-tensors quantizations for native vLLM v0.21.0+ deployment.

This release: Provisional tier — datafree RTN (weight-only rounding, no calibration corpus). A gold AutoRound re-quant is scheduled; 88plug architecture forbids new provisional W4A16 uploads.
