AI Features
Enable Builder Copilot test data access- When enabled, the Builder Copilot can access workflow testing execution data from the current session to generate more context-aware and precise configuration suggestions. When disabled, suggestions are based only on the workflow definition and user input.
AI Models
Blink supports two options for AI infrastructure:- Blink (recommended) – Uses Blink-managed AI infrastructure through Blink’s Amazon Bedrock account. This is the default option and provides a fully managed experience, with all AI requests routed through Blink.
- Amazon Bedrock – Uses your own Amazon Bedrock account. When selected, all AI-related requests are executed through your AWS infrastructure, giving you full control over your AI resources and billing.
Amazon Bedrock Prerequisites
- An AWS account with permission to deploy CloudFormation stacks and create IAM roles.
Configuration Amazon Bedrock as the AI Provider
Note your External ID
Blink automatically generates a unique External ID for your account and displays it on screen.
What is the External ID?It is a secret token that Blink embeds in every
AssumeRole request. Your IAM trust policy must require it, which prevents any other AWS account from assuming your role even if they know your Role ARN. Do not share it.Enter your AWS Account ID and IAM Role Name
Fill in:
-
AWS Account ID — the 12-digit numeric ID of the AWS account where Blink should operate (e.g.
123456789012). -
IAM Role Name — the name you want to give the IAM role that Blink will assume. The default suggestion is
BlinkBedrockExecutionRole; you can use any name that fits your naming conventions.
Deploy the IAM Role via CloudFormation
Click Open in AWS Console. This opens the AWS CloudFormation quick-create page with all parameters pre-filled:
In the AWS Console, scroll to the bottom, acknowledge the IAM capability checkbox, and click Create stack. Wait for the stack status to reach
| Parameter | Value |
|---|---|
| Stack name | blink-bedrock-access |
| External ID | your External ID from step 3 |
| Role Name | the name you entered in step 4 |
CREATE_COMPLETE (usually under 2 minutes).What does the stack create?A single IAM role in your account. The role’s trust policy allows Blink’s AWS account to assume it — but only when the correct External ID is presented.The role’s permission policy grants the following actions, scoped to Anthropic foundation models and cross-region inference profiles only:
bedrock:InvokeModelbedrock:InvokeModelWithResponseStreambedrock:Conversebedrock:ConverseStreambedrock:CountTokens
Test the connection
Return to the Blink AI Settings page and click Test connection. Blink will attempt to assume the role and invoke a lightweight Bedrock call using the values currently in the form - no need to save first.A success confirmation means the role and permissions are correctly configured.
Reverting to Blink’s Default Provider:Switch the AI Provider dropdown back to Blink and save. The IAM role in your AWS account is not deleted automatically — you can clean it up by deleting the
blink-bedrock-access CloudFormation stack.Required Bedrock Model Access
The customer must enable access to the following Anthropic foundation models in their AWS account before the integration will work. All are from the Anthropic provider in Bedrock.Note: All models in the table must be enabled
| Model | Bedrock Model ID |
|---|---|
| Claude Sonnet 4 | anthropic.claude-sonnet-4-20250514-v1:0 |
| Claude Sonnet 4.6 | anthropic.claude-sonnet-4-6 |
| Claude Haiku 4.5 | anthropic.claude-haiku-4-5-20251001-v1:0 |
How to Confirm a Model is Ready:Go to AWS Console → Amazon Bedrock → Playgrounds → Chat, select the model, and send a test message. A successful response confirms the model is accessible.
