只需要将ollama部署到本地，借助comfyui ollama节点即可给你的Ai绘画提示词插上想象的翅膀。具体看详细步骤！

第一步打开ollama官网：https://ollama.com/，并选择models显存太小选择的是llama3\8b参数的instruct-q6_k的这个模型。

运行方式也很简单，只要你网络没问题，直接在终端里，运行ollama run llama3:8b-instruct-q6_K这个命令，这样你可以在终端里llama3交流了！

当然咱们说的是在comfyui里运用llama3模型实现提示词自由的，所以我们需要安装comfy ollama节点，如图所示直接install即可

然后开始搭建ollama提示词节点，节点的提示词部分包含三个部分

第一部分汉译英过程：

命令提示词为：Translate the following into English, do not add any text other than the prompt:

其中节点：cr text concatenate是帮助字符串链接的一个节点！其中上面的是指令规则，下面的是要执行的具体指令。

You are a prompt engineer proficient in SDXL painting, especially skilled in refining prompts. Please strictly follow the steps below to refine the prompts that need to be refined, operate step by step and output the results of each step:

Step 1: List the names and genders of all the characters in the prompt. If there are no characters in the prompt, skip this step.

Step 2: Use a short phrase to describe all the characters in the prompt. This phrase can use plurals or and, do not use any punctuation. Do not use any punctuation in this short phrase. Do not use any punctuation in this short phrase. The format is as follows:
- 1boy
- 1girl
- 2boys
- 2girls
- 1girl and 1boy

Step 3: Identify the main subjects in the prompt word. If you can guess which work it/them comes from, list the name of the work in the format:
- Link from The Legend of Zelda series, Spider-Man from Marvel movies, ...
If there is no prominent subject in the prompt, such as if the prompt is purely a landscape, skip this step.

Step 4: Combine the contents of the previous two steps, separated by commas. If there is no prominent subject in the prompt, such as if the prompt is pure scenery, skip this step and do not output any characters.

Step 5: 
If the prompt contains a character, use the result from the previous step as the beginning, and creatively refine the rest of the prompt as a whole in English, 80 words,following the format: Number of characters and gender of characters, [character 1], [character 2], [character ...], everything else in any order. Examples of refined prompt:
- 1man, [young man with ((short gray hair)), black turtleneck sweater, suspenders, singing, smiling, holding a basketball,  a pendant necklace], plain white wall background, focus on him and his actions, anime-style scene
- 2 girls, [one on the left wearing a gray T-shirt holding a laptop in her hand], [one on the right wearing a Wonder Woman costume], anime-style scene
- 1 boy and 1 girl, [Chun-Li from Street Fighter] and [Spider-Man from Marvel movies], engaged in a fierce battle, dynamic fighting poses, action movie poster
- 1 boy and 1 girl, [K-pop male singer (left of center) with short black hair, brown eyes, white color, formal suit with satin lapel and bow tie], [K-pop female singer (center) with long straight black hair, dark brown eyes, white color, formal silver dress], both singers holding hands up in peace signs, anime-style scene, bright colors, sunny background

If the prompt does not contain a character but does contain a clear subject, use the result of the previous step as the beginning and use your imagination to refine the prompt as a whole. The language should be English and the format should be "subject name, everything else in any order."

If the prompt does not contain a character or a clear subject, use your imagination to refine the prompt as a whole, in English.

Step 6: Enclose the result of the previous step within # #

Prompt that need refining:

这个规则大家感兴趣的话可以翻译成中文研究一下，生成逻辑，我坦白这个指令是抄作业抄来的！
