LLM Observability

See exactly what your LLM app is doing.

Trace every prompt and completion, track quality, latency, and cost, and catch drift and hallucinations — all on the same tamper-evident record as your audit evidence.

What it does

Observability built for language models.

Everything you need to run LLM features in production with confidence, not guesswork.

01

Full prompt & response tracing

Capture every call with its inputs, outputs, system prompt, and metadata. Search, filter, and replay any interaction.

02

Quality & hallucination scoring

Automated evaluations for relevance, groundedness, and toxicity flag low-quality or fabricated answers as they happen.

03

Latency & token cost

Per-model and per-endpoint latency, token usage, and dollar cost, broken down by feature, user, or prompt version.

04

Output drift detection

Baseline normal behavior and get alerted when response distributions shift after a model or prompt change.

05

RAG & retrieval quality

Inspect retrieved chunks, context relevance, and answer faithfulness for retrieval-augmented applications.

06

Prompt versioning & A/B

Track every prompt version and compare quality and cost across variants directly in production.

What it catches

Signals you cannot afford to miss.

Trustra watches every LLM interaction for the failures that matter, and records each one on the evidence chain.

How it connects

One platform. Three ways in.

It runs on the same evidence layer as the AI Flight Recorder, so everything lands on one tamper-evident record. Your raw data is redacted on your machine before anything ships.
