Early-stage teams building agents know they need evals and observability. But the cost and time commitment often push it down the priority list.
Braintrust for Startups gives early-stage companies access to the same platform that Lovable, Browserbase, and Greptile run in
Use the Braintrust .NET SDK for tracing and evaling AI in C#.
Install the core package plus provider integrations for OpenAI, Anthropic, or the Microsoft Agent Framework. Run evals with custom test cases and scoring functions, or add automatic instrumentation via OpenTelemetry.
Topics has a dedicated page that shows all clusters generated from your production logs.
Compare past and present groupings to understand how user behavior evolves over time and gain visibility into how Topics categorizes conversations, complaints, and feature requests.
I’ve seen a lot of confusion about how to best leverage the new family of GPT 5.6 models, and honestly, sameeee! Running this eval helped me pin down which models I should use (or have an agent use) to build effective code without burning extra tokens and dollars.
We evaled the GPT-5.6 family, plus Anthropic's Fable, Opus 4.8, and Sonnet 5, on the key building blocks of agentic workflows.
Then we broke results down by task type and difficulty and turned them into a decision map you can route against.
Here's what we found.

The family-level results show data transforms are nearly solved for the OpenAI models, symbolic rules pull them apart, and the Anthropic rows are dragged down by refusals rather than by wrong answers.
If you're building a voice agent, picking the right speech-to-text model is not obvious. Every provider claims to be accurate, fast, and production-ready, but the benchmarks they publish rarely look like actual traffic.
We used Braintrust to build a controlled eval across six
Your agent is in production. Now you need to understand what it is doing, where it is failing, and what to improve next.
Join our live workshop to build a repeatable workflow for turning agent behavior into evals, measuring improvements, and catching regressions.

The Braintrust Go SDK enables automatic instrumentation with no code changes using Orchestrion, or the use of manual middleware for explicit control.
Supports OpenAI, Anthropic, Google Gemini, Google ADK, and more.
Phrase search breaks when every word is common but the exact sequence is rare. At 100TB+ of agent traces, queries time out and traditional databases fail.
Brainstore uses shingled bloom filters, indexing trigrams instead of tokens.
On a 290 GB dataset, 98.5% of segments were
