Braintrust Release notes and new features

November 2026

Braintrust now supports in-browser thread translation and updates its CLI to support optional MCP telemetry and improved trace continuation. The update also adds support for recording model variants in coding-agent sessions.

October 2026

Braintrust now supports MCP tracing for tool calls and prompt requests in its SDKs. Additionally, SQL queries can now be executed asynchronously to handle large exports and long-running operations.

October 2026

Pattern severity Patterns assigns severity to findings so you can prioritize by impact and filter the list by severity. You can correct a severity with an optional reason, and Loop preserves your correction in later investigations.

October 2026

SQL charts Build dashboard charts from a SQL query, and switch between the query text and a visual builder that edits the same query. Plot the results as time series, top lists, or tables. Braintrust adds the dashboard's timeframe, filters, and grouping to the query when the chart renders, so the same chart works on any dashboard you paste it into.

August 2026

Dashboards Monitoring views are now dashboards, with a dedicated page per dashboard and a project-scoped list to browse, search, and star them. Start from an empty dashboard, clone the built-in Cost and quality dashboard, or duplicate an existing one, then rename or delete it from the Dashboard actions menu.

July 2026

Pairwise scoring When you compare two experiments in diff mode, you can now record which one produced the better output for each row. Braintrust aggregates these head-to-head judgments into a win rate, so you can run A-vs-B human evaluations without configuring a separate scoring function. See Pairwise scoring for details.

June 2026

{/* ### Asynchronous queries Long-running SQL queries can now run asynchronously instead of timing out as a single synchronous request. Submit a query to async API endpoints and Braintrust executes it in the background, materializing results for paginated retrieval.

May 2026

Topics pricing Topics now uses monthly included credits across all plans: $10/month on Starter and $249/month on Pro as a launch promotion for the first 3 months, reverting to $100/month after. Overage charges apply once credits are used up, at $0.06/MTok input and $0.40/MTok output, uniform across plans. Credits do not roll over month-to-month.

February 2026

TypeScript auto-instrumentation Braintrust now supports auto-instrumentation for TypeScript, enabling automatic tracing of all LLM calls with minimal setup. Topics for automated log insights Topics automatically analyze and classify logs to surface patterns and insights without manual review.

April 2026

Translate message content in traces You can now translate any message or string field in a trace without leaving the UI.

Choose from English, Spanish, French, German, Japanese, and Chinese, or type any language name.

January 2026

Auto-instrumentation for Python, Ruby, and Go Braintrust now supports auto-instrumentation for Python, Ruby and Go, enabling zero-code tracing for most providers. For any other providers, use manual wrapping . Temporal integration Braintrust now integrates with Temporal , a durable execution platform for building reliable distributed applications.

December 2025

Claude Code integration You can now use Braintrust with Claude Code , Anthropic's agentic coding tool. The integration automatically traces Claude Code sessions to give you insight into LLM calls, tool usage, and performance, while enabling Claude to query logs, fetch experiment results, and log data using natural language, especially useful when writing...
