Deepchecks LLM Evaluation 0.39.0 Release

We're excited to announce version 0.39 of Deepchecks LLM Evaluation - introducing per-application access control, enhanced prompt properties with descendant data access, Google ADK integration, and CloudWatch metrics for SageMaker deployments. This release strengthens access control granularity, expands framework support, and provides deeper insights into complex agentic workflows.

Deepchecks LLM Evaluation 0.39.0 Release:

🔐 Per-Application Access Control (New RBAC Tier)
🌳 Prompt Properties: Access Descendant Data
🤖 Google ADK Integration
💡 AI Assistant for Documentation
📊 CloudWatch Integration for SageMaker Deployments
⚠️ Deprecations & API Changes

What's New and Improved?

Per-Application Access Control (New RBAC Tier)

Deepchecks now supports a second tier of access control that enables fine-grained application-level permissions. When enabled, users can be granted access to specific applications rather than having automatic access to all applications in the organization.

What this means:

• Granular Access Control - Admins and Owners can specify which applications each user can access when inviting users or updating permissions
• Enhanced Security - Users only see and can access applications they've been explicitly granted access to

This feature is particularly valuable for organizations with multiple teams or applications that require stricter data access boundaries.

Prompt Properties: Access Descendant Data

Prompt properties can now access data from descendant (child) spans in hierarchical workflows, enabling more comprehensive evaluation of complex agentic use-cases.

What's new:

• Descendant Scopes - Add scopes to your prompt properties to access data from child spans at different levels
• Granular Control - Specify depth levels, filter by interaction types, and select which data fields to include from descendant spans
• Flexible Configuration - Each scope can be configured independently, allowing you to gather different types of information from different parts of the hierarchy

Value:

This enhancement enables you to create highly tailored properties for agentic workflows. For example, you can evaluate whether all tool calls in an agentic interaction were appropriate by accessing all descendant Tool spans, or evaluate the quality of responses from an agent's direct LLM children by looking one level down at LLM spans only.

The Data component provides full flexibility over which data fields are sent to the LLM, ensuring token efficiency by only including what's needed for evaluation.

Google ADK Integration

Deepchecks now integrates seamlessly with Google ADK, enabling automatic trace collection and evaluation for Google ADK workflows.

What you get:

• Automatic Instrumentation - Uses OTEL + OpenInference to automatically instrument Google ADK interactions
• Rich Traces - Captures LLM calls, tool invocations, and agent-level spans within the graph
• Simple Setup - Register with Deepchecks through a single register_dc_exporter call
• Full Evaluation - Benefit from Deepchecks' observability, evaluation, and monitoring capabilities

Google ADK joins the popular frameworks we're already integrated with - CrewAI and LangGraph - expanding Deepchecks' support for the most widely-used agentic frameworks.

Deprecations & API Changes (Public Endpoints)

As part of ongoing improvements to our API surface, we’re beginning the deprecation process for several public API endpoints. These endpoints will be removed after three upcoming milestones, following the same policy used for SDK deprecations.

Endpoints being deprecated:

• GET /reference/listappversions
• POST /reference/createappversion
• POST /reference/publiccreateinteractions

SDK upgrade strongly recommended The newer SDK versions include improvements aligned with the new endpoints and permissions model, and provide clearer, more helpful messaging.

Improved permission handling With the updated access control model, API responses now return 403 in cases where:

• the application does not exist, or
• the user does not have permission to access the application. The latest SDK improves this experience by explicitly surfacing “application not found” when applicable (the most common case).

We’re excited to announce version 0.38 of Deepchecks LLM Evaluation - introducing framework-agnostic data ingestion for agentic workflows, a more expressive Avoidance evaluation property, and a new Metric Viewer role. This release expands who can use Deepchecks, improves failure signal quality, and strengthens access control and platform clarity.

Deepchecks LLM Evaluation 0.38.0 Release:

• 🧩 Framework-Agnostic Agentic Data Ingestion
• 🚫 Avoided Answer → Avoidance (Enhanced Property)
• 🔐 New RBAC Role: Metric Viewer
• 🤖 New Models Available for LLM-Based Features
• ⚠️ SDK Deprecation Notice: send_spans()

What's New and Improved?

Framework-Agnostic Agentic Data Ingestion

Deepchecks now supports uploading agentic and complex workflow data via the SDK, without relying on automatic tracing from a supported framework. This enables full observability and evaluation for teams using custom frameworks, in-house orchestration layers, or unsupported agent runtimes.

You can manually structure and send sessions, traces and spans to Deepchecks while still benefiting from the full evaluation, observability, and root-cause analysis capabilities.

For a step-by-step guide, click here.

Avoided Answer → Avoidance (Enhanced Property)

The existing Avoided Answer property has been upgraded to Avoidance, providing richer and more actionable signals.

What changed:

• Previously: a binary (0/1) score indicating whether an answer was avoided.
• Now: a categorical property that distinguishes between:
  • valid — the input was not avoided
  • Specific avoidance modes (e.g. policy-based, lack of knowledge, safety constraints, and more)

This enables clearer diagnosis of why an answer was avoided and supports more meaningful aggregation and analysis across versions.

📌 Deprecation note: The legacy Avoided Answer property is deprecated but will continue to function for existing applications.

For full property definitions and migration details, click here.

New RBAC Role: Metric Viewer

We’ve added a new role to Deepchecks Role-Based Access Control: Metric Viewer.

This role is designed for stakeholders who need high-level insights without access to raw data.

Metric Viewer capabilities:

• Read-only access to aggregated metrics and evaluation results
• Access limited to the version level
• ❌ No access (via UI or SDK) to raw spans and traces
• ❌ No write permissions

This complements the existing Viewer role by enabling stricter data-access boundaries for security-sensitive environments.

To learn more about Deepchecks RBAC roles, click here.

New Models Available for LLM-Based Features

The following models are now supported:

• GPT-5.1
• Amazon Nova 2 Lite
• Amazon Nova Pro

These models can be selected for evaluation, analysis, and automation features across the platform.

SDK Deprecation Notice: send_spans()

The SDK function send_spans() has been renamed to log_spans_file() to better reflect its behavior and usage.

📌 Deprecation notice: send_spans() is now deprecated and will remain supported for the next few releases. We recommend migrating to log_spans_file() to ensure forward compatibility.

Updated SDK documentation and examples reflect the new function name.

Trace logging with instrumentation

We’ve just introduced native support for trace logging via OpenTelemetry and OpenInference 🎉.

Now, you can automatically capture and centralize traces and spans from your LLM and agentic frameworks into Deepchecks - no more manual logging required. If you’re already using frameworks with built-in instrumentors (like CrewAI, LangGraph, and others), setup is seamless and requires only a few lines of code for configuration.

This makes it easy to collect rich, structured trace data from your agents and pipelines, and immediately make it available for:

• Evaluation: Run properties and analyses directly on trace-level data.
• Monitoring: Keep track of performance across workflows.
• Debugging: Quickly drill down into problematic spans, traces and versions.

This ensures you get the deepest possible visibility with minimal effort.

Configurable Processing Speed for Deepchecks On-Prem & SageMaker products

For our non-SaaS deployments, evaluation speed depends on your own LLM capacity. To reduce rate limits and bottlenecks, you can now choose between three processing modes—fast, balanced, or reduced load - so evaluations always complete smoothly at the pace that fits your setup.

Save Filter Presets for Quick Navigation

Tired of reapplying the same filters and sorts? You can now save your setup as a preset on the Interactions screen, then reload it with a single click. This makes it effortless to jump back to your most useful views and keep analyses consistent across sessions.

Version Comparison CSV Export

Need to take your version comparisons beyond the UI? You can now export comparison results directly to CSV for deeper analysis.

• Review all selected versions side by side.
• Access details like overall performance, system metrics, and property-level breakdowns.
• Extend analysis using your own tools - filter, aggregate, or merge with external data sources.

This makes it simple to share results across teams and continue working in the format that best fits your workflow.

Organization-level logs across applications

Previously, logs were only available per application. Now, you can access a centralized log view for your entire organization - covering all applications - in the Workspace Settings screen (top-right).

This release focuses on clarity, speed, and smarter insights: visualize property performance over time, optimize evaluation guidelines with AI, track processing status at a glance, and jump straight to relevant data with new hyperlinks and filters.

This gives you a clearer, data-driven view into what’s driving performance.

Processing Status Indicators for Interactions & Sessions

Keep tabs on what’s done and what’s still running:

• In Progress: Analysis steps (property calculations, annotations, topic inference, similarity checks, etc.) are still underway.
• Completed: Everything’s finished, and results are ready.

Where to see it:

• Single Interaction View: Status icon at the top denotes real-time progress.

• Interactions List: Each row shows an icon (with hover text) to quickly assess readiness.
• Sessions List: Each session displays a summary status—completed only when all interactions are done.

This way, you always know exactly what’s ready to review.

See more details here: https://llmdocs.deepchecks.com/docs/interaction-and-session-completion-status

Click-to-Filter from Score Breakdown

In the Score Breakdown component, now clicking any property or annotation reason instantly filters the Interactions screen to show only relevant items. It makes digging into causes intuitive and fast.

Reasoning for N/A Properties

When a property is marked N/A, you’ll now see a brief explanation—why it couldn’t be calculated. Over the next few weeks, this reasoning will be extended to cover more property types, offering transparency and aiding debugging.

Hyperlinked Examples in Failure Mode Analysis

Failure Mode Analysis now outputs interactive examples - every example includes a hyperlink that opens the specific interaction in a new window. This makes deep-dives from summaries directly actionable.

• We’ve also added time-range-aware insights to Production. Simply adjust the global time-range filter, and your insights will update accordingly—helping you focus on recent data or specific time periods of interest.

Identify better versions and interactions in comparisons

• The version comparison view now highlights which version—and which specific interactions—perform better, based on numerical property analysis.
• Interaction-Level Star Indicator: Each interaction pair is evaluated using the average of the first three pinned numerical properties (often your most critical metrics). The higher-scoring interaction gets a star, and ties get stars for both.
• Version-Level Star Indicator: The version with a majority of “better” interactions earns a star, giving you an at-a-glance winner.
• Hover for explanation: Tooltips clarify the reasoning behind each star selection.

“Sticky” versions for easier comparison

• You can now pin (“stick”) versions to the top of the Versions screen by clicking the up-arrow icon next to them. This keeps them in view while you sort, filter, or explore other versions—perfect for focusing on a few key versions.

Custom guidelines for Failure Mode Analysis

• Failure Mode Analysis now supports user-provided guidelines. You can supply assumptions, suspected failure modes, or specific areas of concern for the analysis agent to focus on—helping tailor summaries to your specific evaluation goals.

Filter interactions by tracing data

• The Interactions page now includes filters for tracing-based system metrics such as total tokens and interaction latency—making it easier to investigate performance patterns or anomalies linked to system behavior.

What's New and Improved?

Switched to LLM-based translation

• We’ve upgraded our translation mechanism to be fully LLM-based, resulting in significantly higher translation quality while also reducing costs. This change ensures more accurate and context-aware translations across the platform.

Score breakdown comparison in Production

• The score breakdown component is now available in the Production environment, giving you deeper insights into model performance. In addition, we’ve introduced a new comparison feature that lets you analyze score breakdowns across two different time ranges. This helps uncover trends, detect potential drifts, and identify which properties may be causing performance issues—or driving improvements—enabling faster root-cause analysis and smarter decisions.

Latency and token metrics in comparison flows

• We've integrated latency and token metrics as key components of our version comparison flow. In the multi-version flow, you can now include the averages of these metrics for a comprehensive overview. Additionally, in the granular comparison mode—which allows you to compare two interactions side-by-side—these metrics are displayed for a detailed, direct comparison.

Improved property page filtering and UX

• We’ve enhanced the Properties page with better filtering and visibility. A new "In auto-annotation" tag clearly marks properties included in the YAML-defined flow. You can now filter properties by attributes like LLM usage, auto-annotation inclusion, property type, and whether they're pinned to the Overview—making it easier to find and manage relevant properties.

We’re excited to introduce several powerful improvements to data visibility, evaluation control, and LLM-based analysis. This release brings new pages, enhanced customization for properties, and more intuitive session-level insights—designed to help you streamline your evaluation workflows and better understand your pipeline’s performance.

Deepchecks LLM Evaluation 0.30.0 Release:

• 📁 New Data Pages: Sessions & Storage
• 📝 Edit LLM-Based Properties
• 🧩 Must/Optional Fields in Prompt Properties
• 📊 High-Level Property Insights
• 🧠 Session Topics per Environment

What's New and Improved?

New Data Pages: Sessions & Storage

• We’ve added a dedicated Sessions page under each version. This view allows quick inspection and comparison of all evaluated sessions, including key metadata: session ID, number of interactions, initial user input, total latency, token usage, session annotation, and interaction types. It's a fast and informative way to analyze session-level data in your version.

• The Storage page provides visibility into unevaluated sessions—available only for the production environment. Sessions are stored here if they were not selected for evaluation based on your configured sampling ratio. This page allows basic filtering, session-level inspection, and the ability to send selected sessions to evaluation, either individually or in bulk. Learn more about sampling here.

Edit LLM-Based Properties

• It’s now possible to edit existing LLM-based properties directly (instead of creating a copy). For prompt properties, numerical or categorical, you can fully update prompt content and instructions as well as the steps and description. For built-in LLM properties, editing focuses on adjusting guidelines—allowing users to better align our prebuilt properties with their specific use cases. See full details in the Property Guide.

Must/Optional Fields in Prompt Properties

• Prompt property creation is now more flexible with Must/Optional field configuration. When defining fields for your prompt logic, you can now mark each as: Must – the field must exist in the interaction for the property to be calculated. Optional – used if present, but doesn’t block evaluation if missing. This helps reduce unnecessary N/As and improves robustness.

High-Level Property Insights

• We’ve added a new RCA capability called Analyze Property Failures—providing LLM-generated summaries of how your properties are performing across the version. This gives a quick, high-level view of the failure points of each property that are causing problems on the interaction and session levels, helping you prioritize areas for version improvement. Read more here.

Session Topics per Environment

• We now support topic assignment at the session level and scoped by environment. While each interaction is still tagged with a topic (available via the SDK), this reflects the session’s topic. Separating topics between evaluation and production environments enables detection of new or unexpected topics appearing only in production.
