Know When Your AI App Breaks (Before Your Users Do)
Silent LLM Failures: Catch Outages and API Errors Instantly
LLM endpoints can silently fail with downtimes, transient API errors, or rate limits. Imagine your AI-powered search, chat, or summarization just stopping without explanation.
Sentry monitors for these failures and alerts you instantly, so you can fix them before your users are impacted.
Stay Available: Real-Time Alerts for LLM Issues
When AI features break (wrong prompts, missing inputs, bad responses, etc) Sentry sends you an alert right away, and gets you to the line of code, the suspect commit, and the developer who owns it.
With support for providers like OpenAI, Vercel AI, and most custom setups that use OpenTelemetry, you can fix issues fast, before they hit more users.
Meet Seer: AI debugger that troubleshoots issues with 94.5% accuracy
You're already juggling complex prompts, unpredictable model output, and edge cases you didn’t even know existed. Now something’s breaking, and you’re stuck guessing.
Seer, Sentry’s AI-powered debugging agent, analyzes your error data to surface root causes fast (with 94.5% accuracy), so you can spend less time digging and more time fixing. It’s our AI... fixing your AI.
Full-Stack Coverage: Monitor More Than Just the LLM
Bugs happen, whether it’s your UI, API, or the code connecting to your LLM. Sentry shows you exactly where things break, with full context and the replay of a user engaging with your frontend.
So when bad data hits your LLM, you know why, and where to fix it.
Tracing & Performance for AI Agents
Debug End-to-End: Full Agent Flows
When something breaks in your AI agent, like a model timing out or a tool failing silently, traditional logs miss the full picture.
Sentry shows the entire agent run: prompts, model calls, tool spans, and errors, linked to the user action that triggered it. You see what broke, why it happened, and how it affected the experience.
Handle Unexpected Model Outputs: Make Sense of Bad AI Responses
Models sometimes return malformed JSON or outputs that don’t match what your app expects. These failures are hard to predict and easy to miss.
Sentry captures the raw model output, shows where it was generated, and traces how it broke downstream. So you can quickly debug the issue and build smarter fallbacks for unpredictable AI behavior.
Speed Up: Track and Optimize LLM Response Times
LLMs can introduce unpredictable delays: one prompt returns in seconds, another takes much longer due to provider load or network issues.
Sentry shows you how your LLM calls are performing over time, with breakdowns by provider, endpoint, and prompt. It’s easy to spot slowdowns, debug performance issues, and keep your AI features fast and reliable for users.
Understand and Optimize Your LLM Costs
Unexpected Spikes: Catch Costly Issues Early
A single large input or unexpected spike can drive up token usage fast.
Sentry gives you real-time visibility and alerts, so you can catch unusual patterns early and keep LLM costs under control.
Budget Protection: Real-Time Alerts for Usage Spikes
Sentry continuously tracks token consumption and LLM-related costs.
If usage patterns shift unexpectedly or costs begin to escalate, Sentry sends immediate alerts so you can investigate, pause, or throttle high-cost activity before it becomes a problem.
Optimize Spend: Analyze and Tune LLM Prompts
Sentry provides granular analytics on token usage and costs at the provider, endpoint, and even individual request level.
You can easily spot which queries, workflows, or features are consuming the most tokens, then dig into the details to optimize prompt design and trim waste.
