Scene-Builder-Qwen3-VL-8B-Instruct

by Xuanyu Liu XuanyuLiu/Scene-Builder-Qwen3-VL-8B-Instruct

Scene-Builder-Qwen3-VL-8B-Instruct is an open-weight model for image and text to text from Xuanyu Liu. It has 8.8B parameters and a 262,144-token context. At 16-bit it needs about 21 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index. It draws 54 downloads a month.

Scene-Builder is the supervised fine-tuning (SFT) model from Scene-Designer: Learning Design Intelligence for Agentic 3D Scene Generation, built on Qwen3-VL-8B-Instruct.

Model Card

Scene-Builder is the supervised fine-tuning (SFT) model from Scene-Designer: Learning Design Intelligence for Agentic 3D Scene Generation, built on Qwen3-VL-8B-Instruct. It learns from complementary scene-construction and scene-critique experience and serves as the starting point for subsequent Scene-GRPO training. This repository releases the SFT checkpoint with full model weights and inference configurations. We define design intelligence as the ability to both design a scene and critique its quality. Scene design concerns constructing physically valid, functionally correct, and layout-coherent scenes, while efficiently correcting errors without unnecessary trial and error when problems…

Questions About Scene-Builder-Qwen3-VL-8B-Instruct

How much GPU memory does Scene-Builder-Qwen3-VL-8B-Instruct need?

About 21 GB at 16-bit and 5.3 GB at 4-bit: the weights (8.8B parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run Scene-Builder-Qwen3-VL-8B-Instruct on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

What is Scene-Builder-Qwen3-VL-8B-Instruct's context length?

262,144 tokens, from the maximum position embeddings in its published configuration.

Merged bf16 weights of the v2.0a checkpoint (v20a-ckpt, step 1800, commit af9df6a0): the LoRA adapters (language layers r16, vision tower) folded into Qwen3-VL-8B-Instruct. Ready for transformers, vLLM, or conversion. The image processor ships the model's resolution contract (minpixels=6500000, maxpixels=7000000): send the largest image you have and let the processor resize it. Status: current best of the series on both transcription benchmarks (Sep 2026) and the first checkpoint with text grounding. Serving demo: the Genizah Reader Space. Diplomatic transcription of handwritten Hebrew-script manuscripts (Hebrew, Aramaic, Judaeo-Arabic) — Cairo Genizah documentary fragments and…

This is a historical merged export, NOT the current flagship. The flagship is v1.9a — adapter + merge instructions at qwen3-vl-8b-hebrew-v19a-ckpt. Full 16-bit merge of v1.5, the Rashi-script generation: pure Rashi glyph perception proven (CER 0.018 on unmemorizable synthetic text), crop-level Vilna gemara solved (CER 0.019), Talmud page-level gemara CER 0.059. Trained at a 3.2 MP resolution floor — use that policy at inference. Vision tower unadapted. Superseded by v1.6+ on print and v1.9a on manuscripts. One line per generation — which checkpoint to use and which are historical: \\ CER over substantive attempts only, alignment-based scorer. Benchmarks differ across generations (Talmud…
