Why it matters

1Detects unhealthy runtime behavior in AI execution, including increased TTFT, dropped throughput, stalled streams, and latency drift.
2Provides intervention capabilities such as retry, reroute, and fallback for AI operations.
3Offers verifiable runtime evidence for detected unhealthy behaviors.
4Designed for MLOps engineers and AI/ML developers managing AI models in production.

overview

What is WAIL?

WAIL is a runtime control layer for AI applications developed by Wailinfra that enables MLOps engineers and AI/ML developers to observe AI execution and detect unhealthy runtime behavior. It provides verifiable runtime evidence for detected unhealthy behaviors and can retry or reroute AI operations when intervention is justified. The platform is designed to operate in complex environments, including those with variable turbidity, low light, and currents, as highlighted by its application in underwater monitoring.

features

Key Features of WAIL

WAIL offers a suite of features designed to ensure the robust and reliable operation of AI models in production environments. These capabilities range from proactive monitoring to automated intervention strategies.

  • Observes AI execution and runtime signals of AI models.
  • Detects unhealthy runtime behavior, including increased Time To First Token (TTFT), dropped throughput, stalled streams, and latency drift.
  • Builds behavioral baselines for AI models to identify deviations.
  • Evaluates risk associated with degraded AI model performance.
  • Makes control decisions such as observe, retry, reroute, or fallback when intervention is justified.
  • Provides verifiable runtime evidence for detected unhealthy behaviors.
  • Supports intelligent detection and classification of objects in complex environments, such as underwater monitoring scenarios.
  • Generates automated alerts for critical events, like unauthorized diving in protected areas.
  • Offers comprehensive data analysis and automated PDF reports with statistical analysis and historical comparisons.

use cases

Who Should Use WAIL?

WAIL is primarily targeted at technical professionals responsible for the deployment, monitoring, and maintenance of AI models in production. Its capabilities are crucial for ensuring the stability and performance of AI-driven applications.

  • MLOps Engineers: For observing runtime signals, building behavioral baselines, and detecting degradation in AI model runtime behavior.
  • AI/ML Developers: For managing AI models in production, evaluating risk, and implementing control decisions when performance degradation occurs.
  • Organizations with Critical AI Deployments: For ensuring high-performance, reliable, and precise AI operations in complex environments, such as underwater monitoring or sensitive infrastructure protection.
  • Teams Requiring Verifiable AI Performance: For generating runtime evidence and automated reports to document AI model behavior and interventions.

how to use

How to Use WAIL

WAIL functions as a runtime control layer, integrating with existing AI deployments to monitor and manage their operational health. Users typically configure WAIL to observe specific AI model signals and define intervention policies.

  • 1Integrate WAIL into your AI application's execution pipeline.
  • 2Configure WAIL to observe specific runtime signals and metrics of your AI models.
  • 3Establish behavioral baselines for normal AI model operation.
  • 4Define thresholds and rules for detecting unhealthy runtime behaviors (e.g., latency spikes, throughput drops).
  • 5Set up intervention strategies, such as automatic retries, rerouting to alternative models, or fallback mechanisms.
  • 6Utilize WAIL's reporting features to analyze detected events and generate verifiable runtime evidence.
