Using the AI SDK

Activepieces integrates with the AI SDK to provide a unified interface for calling LLMs across multiple AI providers. Here’s an example on how to use the AI SDK’s generateText function to call an LLM in your actions. 
import { SUPPORTED_AI_PROVIDERS, createAIModel, aiProps } from '@activepieces/common-ai';
import { createAction, Property } from '@activepieces/pieces-framework';
import { LanguageModel, generateText } from 'ai';

export const askAI = createAction({
  name: 'askAi',
  displayName: 'Ask AI',
  description: 'Generate text using AI providers',
  props: {
    // AI provider selection (OpenAI, Anthropic, etc.)
    provider: aiProps({ modelType: 'language' }).provider,
    // Model selection within the chosen provider
    model: aiProps({ modelType: 'language' }).model,
    prompt: Property.LongText({
      displayName: 'Prompt',
      required: true,
    }),
    creativity: Property.Number({
      displayName: 'Creativity',
      required: false,
      defaultValue: 100,
      description: 'Controls the creativity of the AI response (0-100)',
    }),
    maxTokens: Property.Number({
      displayName: 'Max Tokens',
      required: false,
      defaultValue: 2000,
    }),
  },
  async run(context) {
    const providerName = context.propsValue.provider as string;
    const modelInstance = context.propsValue.model as LanguageModel;

    // The `createAIModel` function creates a standardized AI model instance compatible with the AI SDK:
    const baseURL = `${context.server.apiUrl}v1/ai-providers/proxy/${providerName}`;
    const engineToken = context.server.token;
    const provider = createAIModel({
      providerName,           // Provider name (e.g., 'openai', 'anthropic')
      modelInstance,          // Model instance with configuration
      engineToken,            // Authentication token
      baseURL,               // Proxy URL for API requests
    });

    // Generate text using the AI SDK
    const response = await generateText({
      model: provider,                                        // AI provider instance
      messages: [
        {
          role: 'user',
          content: context.propsValue.prompt,
        },
      ],
      maxTokens: context.propsValue.maxTokens,               // Limit response length
      temperature: (context.propsValue.creativity ?? 100) / 100, // Control randomness (0-1)
      headers: {
        'Authorization': `Bearer ${engineToken}`,            // Required for proxy authentication
      },
    });

    return response.text ?? '';
  },
});

​
AI Properties Helper

Use aiProps to create consistent AI-related properties: 
import { aiProps } from '@activepieces/ai-common';

// For language models (text generation)
props: {
  provider: aiProps({ modelType: 'language' }).provider,
  model: aiProps({ modelType: 'language' }).model,
}

// For image models (image generation)
props: {
  provider: aiProps({ modelType: 'image' }).provider,
  model: aiProps({ modelType: 'image' }).model,
  advancedOptions: aiProps({ modelType: 'image' }).advancedOptions,
}

// For function calling support
props: {
  provider: aiProps({ modelType: 'language', functionCalling: true }).provider,
  model: aiProps({ modelType: 'language', functionCalling: true }).model,
}

​
Advanced Options

The aiProps helper includes an advancedOptions property that provides provider-specific configuration options. These options are dynamically generated based on the selected provider and model. To add advanced options for your new provider, update the advancedOptions property in packages/pieces/community/common/src/lib/ai/index.ts: 
// In packages/pieces/community/common/src/lib/ai/index.ts
advancedOptions: Property.DynamicProperties({
    displayName: 'Advanced Options',
    required: false,
    refreshers: ['provider', 'model'],
    props: async (propsValue): Promise<InputPropertyMap> => {
        const provider = propsValue['provider'] as unknown as string;

        const providerMetadata = SUPPORTED_AI_PROVIDERS.find(p => p.provider === provider);
        if (isNil(providerMetadata)) {
            return {};
        }

        if (modelType === 'image') {
            // Existing OpenAI options
            if (provider === 'openai') {
                return {
                    quality: Property.StaticDropdown({
                        options: {
                            options: [
                                { label: 'Standard', value: 'standard' },
                                { label: 'HD', value: 'hd' },
                            ],
                            disabled: false,
                            placeholder: 'Select Image Quality',
                        },
                        defaultValue: 'standard',
                        description: 'Standard images are less detailed and faster to generate.',
                        displayName: 'Image Quality',
                        required: true,
                    }),
                };
            }

        return {};
    },
})
The advanced options automatically update when users change their provider or model selection, ensuring only relevant options are shown.

​
Adding a New AI Provider

To add support for a new AI provider, you need to update several files in the Activepieces codebase. Here’s a complete guide: Before starting, check the Vercel AI SDK Providers documentation to see all available providers and their capabilities.

​
1. Install Required Dependencies

First, add the AI SDK for your provider to the project dependencies: 
npm install @ai-sdk/openai

​
2. Update SUPPORTED_AI_PROVIDERS Array

First, add your new provider to the SUPPORTED_AI_PROVIDERS array in packages/ai-providers-shared/src/lib/supported-ai-providers.ts: 
import { openai } from '@ai-sdk/openai' // Import the OpenAI SDK

export const SUPPORTED_AI_PROVIDERS: SupportedAIProvider[] = [
  // ... existing providers
  {
    provider: 'openai',                                    // Unique provider identifier
    baseUrl: 'https://api.openai.com',                    // OpenAI's API base URL
    displayName: 'OpenAI',                                // Display name in UI
    markdown: `Follow these instructions to get your OpenAI API Key:

1. Visit: https://platform.openai.com/account/api-keys
2. Create a new API key for Activepieces integration.
3. Add your credit card and upgrade to paid plan to avoid rate limits.
`,                                                        // Instructions for users
    logoUrl: 'https://cdn.activepieces.com/pieces/openai.png', // OpenAI logo
    auth: {
      headerName: 'Authorization',                        // HTTP header name for auth
      bearer: true,                                       // Whether to use "Bearer" prefix
    },
    languageModels: [                                     // Available language models
      {
        displayName: 'GPT-4o',
        instance: openai('gpt-4o'),                       // Model instance from AI SDK
        functionCalling: true,                            // Whether model supports function calling
      },
      {
        displayName: 'GPT-4o Mini',
        instance: openai('gpt-4o-mini'),
        functionCalling: true,
      },
    ],
    imageModels: [                                        // Available image models
      {
        displayName: 'DALL-E 3',
        instance: openai.image('dall-e-3'),              // Image model instance
      },
      {
        displayName: 'DALL-E 2',
        instance: openai.image('dall-e-2'),
      },
    ],
  },
];

​
3. Update createAIModel Function

Add a case for your provider in the createAIModel function in packages/shared/src/lib/ai/ai-sdk.ts: 
import { createOpenAI } from '@ai-sdk/openai' // Import the OpenAI SDK

export function createAIModel<T extends LanguageModel | ImageModel>({
    providerName,
    modelInstance,
    engineToken,
    baseURL,
}: CreateAIModelParams<T>): T {
    const isImageModel = SUPPORTED_AI_PROVIDERS
        .flatMap(provider => provider.imageModels)
        .some(model => model.instance.modelId === modelInstance.modelId)

    switch (providerName) {
        // ... existing cases
        case 'openai': {
            const openaiVersion = 'v1'                     // OpenAI API version
            const provider = createOpenAI({
                apiKey,                                     // OpenAI API key
                baseURL: `${baseURL}/${openaiVersion}`,    // Full API URL
            })
            
            if (isImageModel) {
                return provider.imageModel(modelInstance.modelId) as T
            }
            return provider(modelInstance.modelId) as T
        }
        default:
            throw new Error(`Provider ${providerName} is not supported`)
    }
}

​
4. Handle Provider-Specific Requirements

OpenAI supports both language and image models, but some providers may have specific requirements or limitations: 
// Example: Anthropic only supports language models
case 'anthropic': {
    const provider = createAnthropic({
        apiKey,
        baseURL: `${baseURL}/v1`,
    })
    
    if (isImageModel) {
        throw new Error(`Provider ${providerName} does not support image models`)
    }
    return provider(modelInstance.modelId) as T
}

// Example: Replicate primarily supports image models
case 'replicate': {
    const provider = createReplicate({
        apiToken: apiKey,  // Note: Replicate uses 'apiToken' instead of 'apiKey'
        baseURL: `${baseURL}/v1`,
    })
    
    if (!isImageModel) {
        throw new Error(`Provider ${providerName} does not support language models`)
    }
    return provider.imageModel(modelInstance.modelId) as unknown as T
}

​
5. Test Your Integration

After adding the provider, test it by:
  1. Configure credentials in the Admin panel for your new provider
  2. Create a test action using aiProps to select your provider and models
  3. Verify functionality by running a flow with your new provider
Once these changes are made, your new AI provider will be available in the aiProps dropdowns and can be used with generateText and other AI SDK functions throughout Activepieces.
