最大的更新莫过于对 Llama 3.2 Vision 视觉模型的支持!ollama 的版本也因此从v0.3.14
直接升级到v0.4.0
。
升级 ollama 后,运行如下命令体验
# 默认运行 11B 大小模型
ollama run llama3.2-vision
# 运行 90B 大小模型,需要显存支持
ollama run llama3.2-vision:90b

的问题>>> /Users/geek/Pictures/ollama-hardwriting.jpg what is the content.
Added image '/Users/geek/Pictures/ollama-hardwriting.jpg'
The image contains a handwritten note in Chinese characters, accompanied by an English translation. The note is divided into three sections:
* **Section 1:** "Ollama" (likely a personal name or title) followed by several Chinese characters.
* **Section 2:** A numbered list with the following items:
* **Item 1:** "Stay hungry, Stay foolish." (an English phrase)
* **Item 2:** A series of Chinese characters
* **Item 3:** Another series of Chinese characters
The image appears to be a personal note or message written in Chinese and English.
从测试来看,手写字体识别中,Llama 3.2 Vision 模型很好的支持英文,无法识别中文,对中文的支持比较差,但是能区分出哪些字符是中文。

>>> which language llama3.2 vision support?
Llama 3.2 Vision supports the following languages:
* English
* German
* French
* Italian
* Portuguese
* Hindi
* Spanish
* Thai
>>> how many size llama3.2 vision has
The Llama 3.2-Vision model is available in two sizes: 11B and 90B.
Llama 3.2 Vision 原生支持英文,对英文内容的识别非常准确,输出支持标准的 MarkDown 格式,并且能够正确理解识别的内容,并进行简单的问答。
感觉可以用来做大陆的英文试卷,比如选择题和阅读理解,后续可以测试下看看效果。

Added image '/Users/geek/Pictures/ollama-hist.png'
The most popular value in this chart is 4, which appears 49 times. This is represented by the tallest bar on the
graph.
>>> how many bar in the chart.
There are seven bars representing different values from one to seven.
>>> sum the value of bar in the chart
To find the sum of the values represented by each bar, we can add up the numbers on the y-axis for each x-axis value.
* Bar 1: 7
* Bar 2: 14
* Bar 3: 28
* Bar 4: 49
* Bar 5: 37
* Bar 6: 17
* Bar 7: 8
Summing these values gives us a total of **160**.
能够理解问题,并结合图标内容给出答案,缺点是不能精确识别图标中的值,需要提高精确度。

The animals in the image are cats. The cat on the left appears to be a long-haired orange and white domestic
shorthair, while the cat on the right seems to be a short-haired brown tabby with a white patch on its chest.

(Animals: Two cats)
This image shows two cats. The left one is an orange and white domestic shorthair, while the right one appears to be
a short-haired brown tabby with a white patch on its chest.
>>> how many cats in this image?
There are 2 cats in this image.
从测试看,Llama 3.2 Vision 能够正确识别动物,并且描述图片的内容,能够计算出有 2 只猫。不足之处是图片格式还不支持 webp
。
Llama 3.2 Vision 11B 在 MacBook Pro 2022, M2x Max 上的内存占用仅有 3.32G,和 Chrome 浏览器占用的内存一个数量级。
加在图片的时间在 30-60ms 之间。理解图片的内容要长的多,耗时在秒级,具体时间取决于图片内容的复杂度,图片越简单,耗时越少,越复杂耗时越久。像 OCR 和手写字体的例子,耗时在 40s。
至于 token 的生成速度,基本都在 25 token/s,能够满足日常使用。

Ollama v0.4.0 最大的特点就是对 Meta Llama 3.2 Vision
视觉模型的支持了。
在实际测试过程中,Llama 3.2 Vision
能够很好的识别并理解图片内容,理解图片的耗时取决于图片内容的复杂度,简单图片耗时在 5s 内,复杂图片也在 1min 内。
11B 模型在 Mac 上的内存占用仅 3G 左右,token 的生成速度在 25Token/s,使用效果上个人认为和 ChatGPT 的图片理解在同一水平,能够满足个人的日常使用需求了。
