Overview
Collection reviews provide a structured workflow for quality assurance and peer review:- Assign reviewers to collections
- Submit reviews with approval, rejection, or pending status
- Add review comments to provide context and feedback
- Track review progress with visual status indicators
- Discuss findings through collection-level comments
- Evaluating LLM output quality before production deployment
- Peer reviewing data quality improvements
- Collaborative debugging of RAG pipeline issues
- Team-based validation of trace collections
Creating a Collection
Before you can review traces together, you need to create a collection. Collections are curated sets of traces organized around a specific theme or purpose.From the Traces Page
1
Navigate to traces
Go to your project’s traces page to see all available traces.
2
Select traces
Use filters to find relevant traces, then select the ones you want to group together. You can filter by:
- Date range
- Search terms (e.g., “refund”, “error”)
- Status codes
- Model used
3
Create collection
Click Create Collection button with your selected traces.
4
Name and describe
Give your collection a descriptive name and explanation:
- Good: “GPT-4 Response Quality - Week 12”
- Good: “Refund Policy Errors - Dec 2024”
- Avoid: “Collection 1” or “Test”
5
Save collection
Click Save to create the collection. It will now appear in your project’s collections list.
From Individual Traces
While viewing a specific trace:- Click Add to Collection button
- Choose an existing collection or create a new one
- The trace is immediately added to that collection
Using Filters to Auto-Create Collections
Save time by creating collections directly from filter results:1
Apply filters
Use the traces filter panel to find specific patterns. For example:
- Date range: Last 7 days
- Search: “refund”
- Status: 200
2
Save as collection
Click Save as Collection to turn all matching traces into a collection.
3
Optional auto-sync
Choose whether new traces matching these filters should automatically be added to the collection.
Collection Types and Use Cases
Bug Investigation- Group all traces related to a specific bug
- Example: “Checkout calculation errors - Issue #234”
- Collect traces showing a new feature in action
- Example: “Multi-language support beta testing”
- Traces where users gave negative feedback
- Example: “Thumbs down responses - December”
- All traces about a specific subject
- Example: “Pricing and billing questions”
- Compare different models or prompts
- Example: “GPT-4o vs GPT-4o-mini - Customer Support”
Adding Reviewers to a Collection
1
Navigate to the collection
Open the collection you want to add reviewers to from your project’s collections list.
2
Click the assignees section
In the collection header, you’ll see an assignees area showing current members. Click the ”+ Add” button or assignee avatars to manage members.
3
Select team members
Choose one or more team members from your organization to add as reviewers.
4
Members are added
Added members will appear with their status set to “Pending” until they submit their review.
Only collection creators can add or remove members from collections.
Submitting a Review
Once assigned to a collection, you can submit your review:- Review the traces: Navigate through the collection’s traces to evaluate the quality, accuracy, and performance
- Add comments: Use the Comments tab to discuss specific findings or ask questions
-
Submit your review: Click your avatar in the assignees section and select one of:
- Approve: The collection meets quality standards
- Request changes: Issues found that need addressing
- Mark as pending: Still reviewing or awaiting additional information
- Add a review comment: Provide context for your decision to help the team understand your reasoning
Review Status Indicators
Collection members are displayed with visual indicators:- 🟢 Green checkmark: Review approved
- 🔴 Red X: Changes requested or rejected
Review Workflow Example
Here’s a typical review workflow for evaluating LLM outputs:1
Create collection
A data scientist creates a collection called “GPT-4 Response Quality - Week 12” containing 50 production traces.
2
Assign reviewers
Two team members are added as reviewers: a senior engineer and a domain expert.
3
Review traces
Each reviewer examines the traces, looking for hallucinations, off-topic responses, or formatting issues.
4
Add feedback
Reviewers add comments on specific traces they find problematic:
“Trace #127 shows hallucination - the model cited a non-existent research paper”
“Overall quality looks good, but 3 traces had formatting inconsistencies”
5
Submit reviews
The senior engineer approves with a comment: “Minor issues, but acceptable for production”The domain expert requests changes: “Need to address the hallucination in trace #127 before deploying”
6
Address feedback
The data scientist filters out the problematic trace, adjusts the prompt, and updates the collection.
7
Re-review
After fixes, the domain expert changes their review to approved.
Managing Collection Members
View All Members
To see all members assigned to a collection:- Open the collection detail page
- The assignees section shows all current members with their review status
- Hover over any member to see their role and review comment (if provided)
Remove a Member
To remove a member from a collection:- Click on the member’s avatar in the assignees section
- Select “Remove from collection”
- Confirm the removal
Using Comments for Discussion
The Comments tab in a collection provides a threaded discussion space for reviewers:Adding a Comment
- Navigate to the Comments tab in the collection
- Type your comment in the text field (max 1000 characters)
- Press Cmd+Enter (Mac) or Ctrl+Enter (Windows) to submit
- Your comment appears with your name and avatar
Comment Best Practices
- Be specific: Reference trace IDs when discussing specific issues
- Provide context: Explain why something is problematic or noteworthy
- Ask questions: Use comments to clarify requirements or get additional input
- Link to traces: Mention trace IDs so team members can easily find what you’re discussing
Collection Status Management
Collections have four status levels that help teams track progress:- Open: Collection is actively being reviewed
- In Progress: Review is underway but not yet complete
- Completed: All reviews submitted and any issues resolved
- Closed: Final status, collection archived
