# Component List & View Credits ## Component List On the "**Workflow Builder**" page, when setting up Automation, App, or AI Chatbot (Mode = Advanced) To add a new node: **Step 1**: Click the **"+" button**.
**Step 2**: The system will display the **"Component List" popup**, from which the user can select the desired node to add.
**Step 3**: The Node will display in the workflow
## Credits ### A - Nodes that Consume Credits On the **"Component List" popup**, for nodes that consume credits in Diaflow, a credit indicator will be displayed.
**Common credit units include:**
Unit TypeApply forCredit Calculation Formula NoteExample
TokenApplied to AI/LLM nodes that generate text output.When the node runs → credit burn = (Input credits × Input tokens) + (Output credits × Output tokens)Round credits using the rule:
– Round to nearest integer
– Minimum = 1 credit
  1. Input credits = 2 credits
  2. Output credits = 10 credits
  3. Input token = 100 tokens
  4. Output token = 150 tokens

-> Burn = 2×100 + 10×150 = 1.700 credits

CharacterApplied to AI/LLM nodes that generate text outputWhen the node runs → credit burn = Output Credits × Number of charactersRound credits using the rule:
– Round to nearest integer
– Minimum = 1 credit
  1. Output Credits = 10 credits
  2. Text = 40 character

-> Burn = 400 credits

ImageApplied to AI/LLM nodes that generate images.When the node runs → credit burn = Output Credits × Number of images
  1. Output Credits = 10 credits
  2. Node generates: 2 images

-> Burn = 20 credits

SecondApplied to AI nodes that process tasks measured in time (per second)When the node runs → credit burn = Output Credits × Duration (seconds)Round credits using the rule:
– Round to nearest integer
– Minimum = 1 credit
  1. Output Credits = 6 credits
  2. Node runs for 20 seconds

-> Burn = 120 credits

RequestApplied to nodes in the "Apps" category.When the node runs → credit burn = Output credit
  1. Output (Admin) = 3 credits
  2. User runs node once

→ Burn = 3 credits

### B - Nodes that Do Not Consume Credits On the **"Component List" popup**, nodes that **do not consume any credits** will also have a clear indicator showing they are free to use.
