LLM Observability Platform

Know your LLM costs before the invoice does

Framewren gives engineering teams real-time visibility into LLM API spend, P50/P95/P99 latency, and token throughput across every model provider.

The problem

LLM costs accumulate silently. Latency regressions slip through. Invoices arrive as surprises.

Most teams get one monthly number from their LLM provider. No per-model breakdown. No cost attribution by feature. No P99 tracking. No alert when a prompt template change doubles token spend overnight.

34%
Average LLM overspend
Engineering teams consistently exceed their LLM budget by a third before detecting the drift. By then, the invoice cycle has already closed.
8 days
Latency regression detection lag
On average, P99 latency regressions from model version updates go undetected for over a week — long after user experience has degraded.
$12K+
Average invoice surprise
The typical "surprise LLM invoice" for a mid-size engineering team exceeds $12K. Most are caused by one poorly-scoped prompt template running at scale.

Core capabilities

Cost, latency, and token throughput — in one place

Three dimensions of LLM infrastructure visibility, updated every 60 seconds, normalized across every provider your team uses.

Real-time cost breakdown

Per-model, per-project, per-team cost attribution updated every 60 seconds. Budget thresholds and anomaly detection fire before you hit the monthly cap.

Latency percentile tracking

P50, P95, and P99 latency charted over time. Catch model version regressions and provider SLA degradation within minutes, not days.

Multi-provider unified view

OpenAI, Anthropic, Gemini, Mistral, Cohere, and self-hosted models — all normalized into a single cost and latency dashboard.

Works with everything

Connect your stack in minutes

One SDK wraps all your LLM clients. No infrastructure changes, no prompt logging, no data retention of your completions.

What teams say

Engineers who stopped flying blind

"We were burning $12K a month on GPT-4 calls we didn't even know were happening. Framewren showed us within 10 minutes of setup."

Head of AI Platform
at a fintech processing payments for SMBs

"The P99 latency alerts caught a regression from a model version update before any users noticed. That's the kind of observability we needed."

Staff ML Engineer
at an enterprise SaaS company

"Every other tool was either too heavy (Datadog) or too shallow. Framewren hits the exact right scope — LLM API visibility, nothing else."
