fal.ai 媒体生成

通过 MCP 使用 fal.ai 模型生成图像、视频和音频。

何时激活

  • 用户希望根据文本提示生成图像
  • 根据文本或图像创建视频
  • 生成语音、音乐或音效
  • 任何媒体生成任务
  • 用户提及“生成图像”、“创建视频”、“文本转语音”、“制作缩略图”或类似表述

MCP 要求

必须配置 fal.ai MCP 服务器。添加到 ~/.claude.json

"fal-ai": {
  "command": "npx",
  "args": ["-y", "fal-ai-mcp-server"],
  "env": { "FAL_KEY": "YOUR_FAL_KEY_HERE" }
}

fal.ai 获取 API 密钥。

图像生成

Nano Banana 2(快速)

generate(
  app_id: "fal-ai/nano-banana-2",
  input_data: {
    "prompt": "未来主义日落城市景观,赛博朋克风格",
    "image_size": "landscape_16_9",
    "num_images": 1,
    "seed": 42
  }
)

Nano Banana Pro(高保真)

  input_data: {
    "prompt": "专业产品照片,无线耳机置于大理石表面,影棚灯光",
    "image_size": "square",
    "num_images": 1,
    "guidance_scale": 7.5
  }
)

常见图像参数

参数类型选项说明
prompt字符串必需描述您想要的内容
image_size字符串squareportrait_4_3landscape_16_9portrait_16_9landscape_4_3宽高比
num_images数字1-4生成数量
seed数字任意整数可重现性
guidance_scale数字1-20遵循提示的紧密程度(值越高越贴近字面)

图像编辑

使用 Nano Banana 2 并输入图像进行修复、扩展或风格迁移:

# 首先上传源图像
upload(file_path: "/path/to/image.png")

# 然后使用图像输入进行生成
generate(
  app_id: "fal-ai/nano-banana-2",
  input_data: {
    "prompt": "same scene but in watercolor style",
    "image_url": "<uploaded_url>",
    "image_size": "landscape_16_9"
  }
)

视频生成

Seedance 1.0 Pro(字节跳动)

最适合:文生视频、图生视频,具有高运动质量。

generate(
  app_id: "fal-ai/seedance-1-0-pro",
  input_data: {
    "prompt": "a drone flyover of a mountain lake at golden hour, cinematic",
    "duration": "5s",
    "aspect_ratio": "16:9",
    "seed": 42
  }
)

Kling Video v3 Pro

最适合:文生/图生视频,带原生音频生成。

generate(
  app_id: "fal-ai/kling-video/v3/pro",
  input_data: {
    "prompt": "海浪拍打着岩石海岸,乌云密布",
    "duration": "5s",
    "aspect_ratio": "16:9"
  }
)

Veo 3(Google DeepMind)

最适合:带生成声音的视频,高视觉质量。

generate(
  app_id: "fal-ai/veo-3",
  input_data: {
    "prompt": "夜晚熙熙攘攘的东京街头市场,霓虹灯招牌,人群喧嚣",
    "aspect_ratio": "16:9"
  }
)

图生视频

从现有图像开始:

generate(
  app_id: "fal-ai/seedance-1-0-pro",
  input_data: {
    "prompt": "camera slowly zooms out, gentle wind moves the trees",
    "image_url": "<uploaded_image_url>",
    "duration": "5s"
  }
)

视频参数

参数类型选项说明
prompt字符串必需描述视频内容
duration字符串"5s""10s"视频长度
aspect_ratio字符串"16:9""9:16""1:1"帧比例
seed数字任意整数可重现性
image_url字符串URL用于图生视频的源图像

音频生成

CSM-1B(对话语音)

文本转语音,具有自然、对话式的音质。

generate(
  app_id: "fal-ai/csm-1b",
  input_data: {
    "text": "Hello, welcome to the demo. Let me show you how this works.",
    "speaker_id": 0
  }
)

ThinkSound(视频转音频)

根据视频内容生成匹配的音频。

generate(
  app_id: "fal-ai/thinksound",
  input_data: {
    "video_url": "<video_url>",
    "prompt": "ambient forest sounds with birds chirping"
  }
)

ElevenLabs(通过 API,无 MCP)

如需专业的语音合成,直接使用 ElevenLabs:

import os
import requests

resp = requests.post(
    "https://api.elevenlabs.io/v1/text-to-speech/<voice_id>",
    headers={
        "xi-api-key": os.environ["ELEVENLABS_API_KEY"],
        "Content-Type": "application/json"
    },
    json={
        "text": "Your text here",
        "model_id": "eleven_turbo_v2_5",
        "voice_settings": {"stability": 0.5, "similarity_boost": 0.75}
    }
)
with open("output.mp3", "wb") as f:
    f.write(resp.content)

VideoDB 生成式音频

如果配置了 VideoDB,使用其生成式音频:

# Voice generation
audio = coll.generate_voice(text="Your narration here", voice="alloy")

# Music generation
music = coll.generate_music(prompt="upbeat electronic background music", duration=30)

# Sound effects
sfx = coll.generate_sound_effect(prompt="thunder crack followed by rain")

成本估算

生成前,检查估算成本:

estimate_cost(
  estimate_type: "unit_price",
  endpoints: {
    "fal-ai/nano-banana-pro": {
      "unit_quantity": 1
    }
  }
)

模型发现

查找特定任务的模型:

search(query: "text to video")
find(endpoint_ids: ["fal-ai/seedance-1-0-pro"])
models()

提示

  • 在迭代提示时,使用 seed 以获得可重现的结果
  • 先用低成本模型(Nano Banana 2)进行提示迭代,然后切换到 Pro 版进行最终生成
  • 对于视频,保持提示描述性但简洁——聚焦于运动和场景
  • 图生视频比纯文生视频能产生更可控的结果
  • 在运行昂贵的视频生成前,检查 estimate_cost
