You can set these environment variables to achieve it. - **CAN_CHANGE_KEYS=[true/false]**: Set this to **false** if you want to keep API Keys hidden and make them unmodifiable. - **LLM=[openai/google/anthropic/ollama/custom]**: Select **LLM** of your choice. - **OPENAI_API_KEY=[Your OpenAI API Key]**: Provide this if **LLM** is set to **openai** - **OPENAI_MODEL=[OpenAI Model ID]**: Provide this if **LLM** is set to **openai** (default: "gpt-4.1") - **GOOGLE_API_KEY=[Your Google API Key]**: Provide this if **LLM** is set to **google** - **GOOGLE_MODEL=[Google Model ID]**: Provide this if **LLM** is set to **google** (default: "models/gemini-2.0-flash") - **ANTHROPIC_API_KEY=[Your Anthropic API Key]**: Provide this if **LLM** is set to **anthropic** - **ANTHROPIC_MODEL=[Anthropic Model ID]**: Provide this if **LLM** is set to **anthropic** (default: "claude-3-5-sonnet-20241022") - **OLLAMA_URL=[Custom Ollama URL]**: Provide this if you want to custom Ollama URL and **LLM** is set to **ollama** - **OLLAMA_MODEL=[Ollama Model ID]**: Provide this if **LLM** is set to **ollama** - **CUSTOM_LLM_URL=[Custom OpenAI Compatible URL]**: Provide this if **LLM** is set to **custom** - **CUSTOM_LLM_API_KEY=[Custom OpenAI Compatible API KEY]**: Provide this if **LLM** is set to **custom** - **CUSTOM_MODEL=[Custom Model ID]**: Provide this if **LLM** is set to **custom** You can also set the following environment variables to customize the image generation provider and API keys: - **IMAGE_PROVIDER=[pexels/pixabay/gemini_flash/dall-e-3]**: Select the image provider of your choice. - Defaults to **dall-e-3** for OpenAI models, **gemini_flash** for Google models if not set. - **PEXELS_API_KEY=[Your Pexels API Key]**: Required if using **pexels** as the image provider. - **PIXABAY_API_KEY=[Your Pixabay API Key]**: Required if using **pixabay** as the image provider. - **GOOGLE_API_KEY=[Your Google API Key]**: Required if using **gemini_flash** as the image provider. - **OPENAI_API_KEY=[Your OpenAI API Key]**: Required if using **dall-e-3** as the image provider. > **Note:** You can freely choose both the LLM (text generation) and the image provider. Supported image providers: **pexels**, **pixabay**, **gemini_flash** (Google), and **dall-e-3** (OpenAI). ### Using OpenAI ```bash docker run -it --name presenton -p 5000:80 -e LLM="openai" -e OPENAI_API_KEY="******" -e IMAGE_PROVIDER="dall-e-3" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ### Using Google ```bash docker run -it --name presenton -p 5000:80 -e LLM="google" -e GOOGLE_API_KEY="******" -e IMAGE_PROVIDER="gemini_flash" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ### Using Ollama ```bash docker run -it --name presenton -p 5000:80 -e LLM="ollama" -e OLLAMA_MODEL="llama3.2:3b" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="*******" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ### Using Anthropic ```bash docker run -it --name presenton -p 5000:80 -e LLM="anthropic" -e ANTHROPIC_API_KEY="******" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="******" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` ### Using OpenAI Compatible API ```bash docker run -it -p 5000:80 -e CAN_CHANGE_KEYS="false" -e LLM="custom" -e CUSTOM_LLM_URL="http://*****" -e CUSTOM_LLM_API_KEY="*****" -e CUSTOM_MODEL="llama3.2:3b" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="********" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` #### Running Presenton with GPU Support To use GPU acceleration with Ollama models, you need to install and configure the NVIDIA Container Toolkit. This allows Docker containers to access your NVIDIA GPU. Once the NVIDIA Container Toolkit is installed and configured, you can run Presenton with GPU support by adding the `--gpus=all` flag: ```bash docker run -it --name presenton --gpus=all -p 5000:80 -e LLM="ollama" -e OLLAMA_MODEL="llama3.2:3b" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="*******" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest ``` > **Note:** GPU acceleration significantly improves the performance of Ollama models, especially for larger models. Make sure you have sufficient GPU memory for your chosen model. ## Generate Presentation over API ### Generate Presentation Endpoint: `/api/v1/ppt/presentation/generate` Method: `POST` Content-Type: `multipart/form-data` > **Note**: Make sure to set `Content-Type` as `multipart/form-data` and not `application/json`. #### Request Body | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | prompt | string | Yes | The main topic or prompt for generating the presentation | | n_slides | integer | No | Number of slides to generate (default: 8, min: 5, max: 15) | | language | string | No | Language for the presentation (default: "English") | | layout | string | No | Presentation theme (default: "general").
