Aetherya LLM Telemetry & Optimization

v1 Coming Soon

An open-source LLM traffic, cost, and observability layer for AI agents and applications. It sits between your application and providers like OpenAI, Anthropic, Gemini, DeepSeek, or OpenRouter. Instead of calling providers directly, developers route requests through ALTO to gain instant visibility into latency, token usage, and costs.

Our Philosophy

Proprietary simulation core.
Open ecosystem tools.

Our cognitive simulation engines and core IP remain proprietary. Everything around it—the tools developers rely on every day—is open, transparent, and built for the community.

PROPRIETARY CORE
  • Cognitive simulation engines
  • World & behavior models
  • Proprietary datasets
  • Differentiated IP
OPEN ECOSYSTEM
  • Developer infrastructure
  • Observability & evaluation
  • Routing & orchestration
  • Agent development tools
Secure core. Open perimeter. Built for innovation.
