Multimodal LLMs in Three Generations: China Leads Gen 2, Google Jumps to Gen 3

What this is

Over the past three years, multimodal LLMs have completed three generations of architectural leapfrogs, moving from a 'translator' mode to a 'native brain' mode.

LLaVA's 2022 solution was the most straightforward: freeze both the visual encoder (the 'translator' that converts images into numbers) and the language LLM, and train only a small bridge in between, turning images into text tokens (the smallest units a model processes) before feeding them into the language model. The Qwen-VL series is the domestic representative of this approach; by Qwen-VL3 in 2024 it had evolved into 'multi-layer injection'—extracting features from different layers of the visual encoder and feeding them into different layers of the language model, preserving more detail.

But this 'translator' mode carries three fundamental flaws: visual information is easily 'digested' by the language model and loses detail; modality distributions don't match; and it can't handle high-resolution images. So the third-generation Gemma4 took the radical step of dropping the standalone visual encoder entirely, slicing images into 'patches' the same size as text tokens and training a single Transformer (a mainstream AI model architecture) from scratch. Our judgment: this is a 'return to origins'—an admission that images and text are fundamentally the same thing, only perceived differently because of how humans sense them.

Industry view

Domestic mainstream players (Alibaba Qwen, SenseTime, Zhipu) are all betting on second-generation 'deep fusion', with products like Qwen-VL3 and GLM-4V performing stably. The third-generation 'native architecture' is led primarily by Google Gemma4, with no comparable domestic LLM on the horizon.

But there are two risks worth our vigilance. First, the 'native architecture' training cost is far higher than the previous two generations—Gemma4's from-scratch multimodal training requires an order of magnitude more compute and data than the 'translator' mode, effectively raising the entry ticket to the one-billion-dollar level, which may squeeze out smaller players. Second, modality conflict has not been truly resolved—processing images and text through the same neural network theoretically means image tasks will 'dilute' language capabilities, a trade-off Google itself acknowledges in its public technical reports.

Some researchers also dissent: the third-generation architecture has so far been validated only in papers and early experiments, with commercial stability far inferior to the already widely deployed second generation. The 'translator' mode being phased out may take three to five years, not one.

Impact on regular people

For enterprise IT: over the next year, multimodal model selection will clearly stratify. Document OCR, table recognition, and contract parsing—essentially 'reading text clearly'—are already adequately handled by the second-generation Qwen-VL3; scenarios like general video understanding and multimodal generation may need to wait for the native architecture to mature.

For individual careers: product managers, content operations staff, and designers will feel the impact first—AI that can 'understand images' can already independently handle competitor screenshot analysis and visual consistency checks for poster copy, and hiring demand for entry-level visual roles may narrow.

For consumer markets: the most direct change consumers will notice is that AI assistants' ability to 'speak about images' will increasingly resemble human behavior rather than a 'search engine with a filter layered on top'—that's a good thing, but be wary: once AI trains images and text as the same kind of input, errors may become harder to detect.

多模态大模型三年走完三代架构 — 中国玩家领跑第二代,Google 抢跑第三代

这是什么

过去三年,多模态大模型完成了三代架构跃迁,从'翻译官'模式走到了'原生大脑'模式。

2022 年 LLaVA 的解法最朴素:把视觉编码器(把图片转成数字的'翻译器')和语言大模型都冻住,只训练中间一座小桥,让图像变成文字 token(模型处理的最小语言单位)后塞给语言模型。Qwen-VL 系列是国内这条路线的代表,到 2024 年的 Qwen-VL3 进化成'多层注入'——从视觉编码器的不同层抽取特征,分别喂进语言模型的不同层,保留了更多细节。

但这套'翻译官'模式有三个根本缺陷:视觉信息容易被语言模型'消化掉'丢失细节、模态分布不匹配、无法处理高分辨率图片。所以第三代 Gemma4 索性砍掉独立视觉编码器,把图片切成和文字一样大的'块',直接用同一个 Transformer(一种主流 AI 模型架构)从头开始训练。判断:这是一次'返璞归真'——承认图像和文字本质上是同一种东西,只是人类感知方式不同。

行业怎么看

国内主流玩家(阿里 Qwen、商汤、智谱)目前都押注第二代'深度融合',Qwen-VL3、GLM-4V 等产品表现稳定;第三代'原生架构'主要由 Google Gemma4 领跑,国内尚无对标大模型。

但值得我们警惕的是两个风险。其一,'原生架构'训练成本远高于前两代——Gemma4 从头训练多模态模型,所需的算力和数据比'翻译官'模式高一个数量级,这等于把入场券抬到了十亿美元级别,中小玩家可能被挤出。其二,模态冲突并未真正解决——把图像和文字用同一套神经网络处理,理论上图像任务会'稀释'语言能力,Google 公开的技术报告也承认了这一权衡。

另外也有研究者持反对意见:第三代架构目前只在论文和早期实验中验证,商业化稳定性远不如已经大规模部署的第二代。'翻译官'模式被淘汰可能还需要三到五年,而非一年。

对普通人的影响

对企业的IT:未来一年,多模态选型会明显分层。文档 OCR、表格识别、合同解析这类'看清文字'任务,用第二代 Qwen-VL3 已足够;通用视频理解、多模态生成等场景,可能需要等待原生架构成熟。

对个人职场:产品经理、内容运营、设计师会最先感受到冲击——能'看懂图'的 AI 已经可以独立完成竞品截图分析、海报文案的视觉一致性检查这类工作,初级视觉相关岗位的招聘需求可能收窄。

对消费市场:消费者最直接的变化是 AI 助手'看图说话'的能力会越来越像人,而不是像'加了一层滤镜的搜索引擎'——这是好事,但也要警惕:当 AI 把图和文当成同一种东西训练后,错误可能更难被发现。
