2. API Key

Your personal OpenAI API Key, required for authentication and accessing OpenAI’s API services.
If you don't have one you should create it:

How to Create an OpenAI API Key

To use the "Generate Text with OpenAI (BYO API Key)" action, you need an OpenAI API key. Below is a step-by-step guide to create one:

Step 1: Sign Up for an OpenAI Developer Account

Visit OpenAI's Platform Website.
Click on Sign Up if you don’t have an account or Log In if you already do.
Choose a sign-up method:
- Google, Microsoft, or Apple account.
- Email and Password (requires at least 12 characters).
Verify your email by clicking the link sent to your inbox.

Step 2: Set Up Your Developer Account

After verifying your email, OpenAI will ask for your name and birthdate.
Enter your organization name (can be your company name or any preferred name).
You can skip inviting team members for now.

Step 3: Generate Your API Key

Once your account is set up, navigate to the API Keys section.
- Go to the OpenAI Dashboard → Select API Keys from the left-hand menu.
Click "Create API Key".
Give your API key a name (optional) and click "Generate".
Copy your API key—it will only be shown once! Store it securely.

Step 4: Add Payment and Credits (Mandatory)

⚠ Your API key will not work unless you add credits to your account.

Click "Continue" after generating your API key.
OpenAI requires payment information to activate API usage.
Add a small amount of credit (e.g., $5) to start using the API.
- Click "Purchase Credits", enter payment details, and confirm.

Step 5: Managing Your API Keys

To find existing API keys, go to Dashboard → API Keys.
You can edit, delete, or create new API keys anytime from this section.

Final Note

Keep your API key private! Never share it or expose it in public repositories.
Monitor your API usage and costs via the Usage section in the OpenAI dashboard.
If your key is compromised, revoke and generate a new one immediately.

With your OpenAI API key ready, you can now configure it in this action to start generating AI-powered content! 🚀

3. Examples

Provide input-output examples to guide the model’s responses. Each example can include:

Use Image – Toggle if an image is included in processing.
Input – The text or image input used in the example.
Output – The expected AI-generated response.

4. System Instructions

Define specific behavior, tone, or style preferences for AI responses. For example:

"Respond formally and concisely."
"Use a friendly and engaging tone."
"Answer in markdown format."

5. Input

The main prompt or user query sent to the OpenAI model. This is the core instruction that guides the AI’s response.

6. Use Image

Turn on this setting if you want to process an image along with text input. This applies to multimodal-capable models.

7. Generation Config

provides fine-tuned control over how the AI model generates responses. By adjusting these parameters, you can balance creativity, consistency, and output length based on your needs.

1. Temperature

🔹 Controls randomness in the output.

Range: 0 to 2.0
Lower values (e.g., 0.2 - 0.5): Output is more focused, predictable, and deterministic (useful for factual answers).
Higher values (e.g., 0.8 - 1.5): Output becomes more creative and varied (useful for brainstorming, storytelling).
Example:
- 0.2: "Paris is the capital of France." ✅ (Fact-based response)
- 1.2: "Paris is a dazzling city where art, history, and romance blend together." ✨ (More creative response)

🔹 Best Practice: Use 0.7 - 1.0 for natural conversations and 0.2 - 0.5 for precise answers.

2. Maximum Length

🔹 Specifies the maximum number of tokens (words + symbols) that the AI can generate.

Tokens: ~1 token ≈ 4 characters in English text (~75 words per 100 tokens).
Example Settings:
- 50 tokens → Short responses
- 200 tokens → Medium-length explanations
- 500+ tokens → Long-form content

🔹 Best Practice:

Keep the limit within your API quota to avoid excessive token usage.
Be aware that the AI counts both input and output tokens when charging for API usage.

3. Top-p (Nucleus Sampling)

🔹 Determines the probability threshold for selecting the next word.

Range: 0 to 1.0
Lower values (e.g., 0.2 - 0.5): More focused, deterministic responses.
Higher values (e.g., 0.8 - 1.0): More diverse, creative responses.

🔹 Example:

Top-p = 0.3 → AI considers only the most probable words (good for technical writing).
Top-p = 0.9 → AI considers a broader range of words (useful for creative writing).

🔹 Best Practice: If using Top-p, keep Temperature lower (e.g., Temperature = 0.7, Top-p = 0.9) for balanced responses.

4. Presence Penalty

🔹 Encourages or discourages repeated topics.

Range: -2.0 to 2.0
Higher values (e.g., 1.5 - 2.0): AI avoids repeating the same topic.
Lower values (e.g., -1.5 - 0): AI is allowed to repeat key points.

🔹 Example:

Presence Penalty = 2.0: AI avoids discussing "climate change" multiple times.
Presence Penalty = -1.0: AI freely repeats key ideas when needed.

🔹 Best Practice: Use higher penalties for brainstorming and lower penalties for FAQs.

5. Frequency Penalty

🔹 Prevents repetitive word usage.

Range: -2.0 to 2.0
Higher values (e.g., 1.5 - 2.0): AI avoids repeating words too often.
Lower values (e.g., -1.5 - 0): AI can reuse words naturally.

🔹 Example:

Frequency Penalty = 2.0: AI varies its vocabulary (good for storytelling).
Frequency Penalty = -1.0: AI repeats important terms (useful for legal/technical documents).

🔹 Best Practice: Use 1.0 - 1.5 for natural variation and 0 for factual accuracy.

6. Output in JSON

🔹 Formats the AI's response as a structured JSON object.

✅ Useful for structured data processing, integrations, and automation.
❌ Not all models support JSON format.

🔹 Example JSON Output:

{
  "response": "The Eiffel Tower is a landmark in Paris.",
  "source": "AI Model"
}

🔹 Best Practice: Enable this only when your automation needs structured data.

Final Notes on Generation Config:

✅ Adjust parameters together for optimal output.
✅ Lower randomness (Temperature, Top-p) for factual tasks. ✅ Increase penalties (Presence/Frequency) to avoid repetitive AI responses. ✅ Use JSON output for structured workflows.

With this detailed control, you can tailor OpenAI’s responses to meet your specific needs! 🚀
