🎨 Text-to-Image Free

A free AI image generation tool. User provides a text description, and the agent generates a corresponding image. No API key required, zero cost. Powered by Pollinations.ai free API.

Usage

User says: "generate an image: a Shiba Inu on a beach drinking coconut water"

The agent performs the following workflow:

Step 1: Extract Prompt

Extract the image description from user input.

Trigger keywords: "generate", "create an image", "draw", "make a picture"

Step 2: Set Parameters

ParameterDefaultDescription
width1024Image width in px
height768Image height in px
modelsanasana / flux / turbo / dreamshaper
nologotrueRemove watermark
seedrandomFixed integer for reproducible results

User can override:

"Generate: cyberpunk Shanghai night view, width 1920 height 1080, use flux model"
"Generate another, use seed=42 for consistent style"

Step 3: Call API

Use exec to run curl against Pollinations.ai:

PROMPT="<your text description>"
WIDTH=1024
HEIGHT=768
SEED=""  # optional: "42"

curl -s --max-time 180 \
  "https://image.pollinations.ai/prompt/$(python3 -c "import urllib.parse; print(urllib.parse.quote('$PROMPT'))")?width=$WIDTH&height=$HEIGHT&nologo=true${SEED:+&seed=$SEED}" \
  -o /tmp/generated_image.jpg

Step 4: Return Result

Return the generated image file to the user.

Model Selection

ModelFeaturesSpeed
sana (default)Latest efficient model, balanced style & detailFast
fluxHigher quality, richer detailModerate
turboFastest generation, good for previewsFastest
dreamshaperArtistic / dream-like styleMedium

As of May 2026, Pollinations.ai default model has been switched to Sana. Older models like stable-diffusion are deprecated. Sana offers better speed-quality balance.

Examples

User: "Generate: cyberpunk Shanghai night, neon lights, flying cars"
→ Agent calls API → returns image ✓

User: "Generate: an orange cat wearing an astronaut helmet, cartoon style, use flux model"
→ Agent calls API → returns image ✓

Notes

  • Free API has queue limits: one request at a time
  • Generation takes ~15-60 seconds (Sana is faster than predecessors)
  • English prompts yield best results
  • Use seed parameter (e.g., &seed=42) for reproducible results
  • Non-commercial use only (Pollinations.ai free tier limitation)

🎨 文生图(免费)

一个免费的AI图片生成工具。用户输入描述性文字,即可生成对应的图片。无需任何API Key,零成本使用。基于 Pollinations.ai 免费API。

使用方法

用户说:"画一张图:一只柴犬在沙滩上喝椰子水"

Agent 执行以下流程:

第一步:提取提示词

从用户输入中提取图片描述文本。

关键词触发:"画一张图"/"生成图片"/"画"/"create"/"generate"

第二步:调整参数

参数默认值说明
width1024图片宽度
height768图片高度
modelsanasana / flux / turbo / dreamshaper
无水印默认去除水印
seed随机固定值可复现相同结果

用户可指定参数:

"画一张图:赛博朋克上海夜景,宽1920高1080,使用flux模型"
"再生成一次,用seed=42保持风格一致"

第三步:调用API

使用 exec 运行 curl 命令调用 Pollinations.ai:

PROMPT="<图片描述文字>"
WIDTH=1024
HEIGHT=768
SEED=""  # 可选:"42"

curl -s --max-time 180 \
  "https://image.pollinations.ai/prompt/$(python3 -c "import urllib.parse; print(urllib.parse.quote('$PROMPT'))")?width=$WIDTH&height=$HEIGHT&nologo=true${SEED:+&seed=$SEED}" \
  -o /tmp/generated_image.jpg

第四步:返回结果

将生成的图片文件返回给用户。

模型选择

模型特点速度
sana(默认)最新高效模型,通用风格,细节出色
flux更高质量,细节丰富稍慢
turbo极速生成,适合快速预览最快
dreamshaper偏向艺术/梦幻风格中等

2026年5月更新:Pollinations.ai 已将默认模型切换为 Sana,前代模型(如stable-diffusion)已下线。Sana在速度和画质间取得更好平衡。

示例

用户:「画一张图:赛博朋克上海夜景,霓虹灯,飞行汽车」
→ Agent 调用API → 返回图片 ✓

用户:「画一张图:一只橘猫戴着宇航员头盔,卡通风格,使用flux模型」
→ Agent 调用API → 返回图片 ✓

注意事项

  • 免费API有队列限制,一次只能处理一个请求
  • 生成时间约15-60秒(Sana模型较前代更快)
  • 建议使用英文提示词获得最佳效果,中文也支持
  • 支持 seed 参数(如 &seed=42)获得可复现结果
  • 仅限非商业用途(Pollinations.ai免费层限制)
