Once configured, PipesHub can transcribe spoken audio into text using OpenAI's Whisper and GPT-4o transcription models. ## Required Fields ### API Key \* The API Key is required to authenticate your requests to OpenAI's transcription services. **How to obtain an API Key:** 1. Log in to your [OpenAI account](https://platform.openai.com/api-keys) 2. Navigate to the API Keys section 3. Create a new secret key 4. Copy the key immediately (it will only be shown once) **Security Note:** Your API key should be kept secure and never shared publicly. PipesHub securely stores your API key and uses it only for authenticating requests to OpenAI. ### Model Name \* The Model Name field defines which OpenAI transcription model you want to use. **Available OpenAI STT models:** * `whisper-1` — OpenAI's Whisper model, supports 50+ languages * `gpt-4o-transcribe` — GPT-4o powered transcription, highest accuracy * `gpt-4o-mini-transcribe` — GPT-4o Mini powered transcription, faster and more cost-effective **How to choose a model:** * For broad language support and general-purpose transcription, use `whisper-1` * For the highest transcription accuracy, use `gpt-4o-transcribe` * For a balance of speed and accuracy at lower cost, use `gpt-4o-mini-transcribe` * Check OpenAI's [speech-to-text documentation](https://platform.openai.com/docs/guides/speech-to-text) for the most up-to-date model options ## Optional Fields ### Model Friendly Name A human-readable label for this configuration, shown in the PipesHub UI instead of the raw model name. Useful when you have multiple configurations of the same provider. ## Configuration Steps As shown in the image above: 1. Click **Configure** on the OpenAI provider card in the STT tab 2. Enter your OpenAI API Key in the designated field (marked with \*) 3. Enter the Model Name (marked with \*), for example `whisper-1` 4. (Optional) Set a **Model Friendly Name** 5. Click **Add Model** to save and validate your credentials > Both the API Key and Model Name are required fields to successfully configure OpenAI STT integration. ## Usage Considerations * Each transcription request counts against your OpenAI API quota and billing * `whisper-1` is priced per minute of audio transcribed * GPT-4o transcription models may be priced differently — check OpenAI's pricing page * Audio files are sent to OpenAI's API servers for processing ## Troubleshooting * If you encounter authentication errors, verify your API key is correct and has not expired * Ensure your OpenAI account has billing enabled * Check that the model name is spelled exactly as shown (e.g. `whisper-1`, not `Whisper-1`) * Verify your account has access to the audio transcription API For additional support, refer to the [OpenAI speech-to-text documentation](https://platform.openai.com/docs/guides/speech-to-text) or contact PipesHub support.
