What This Is

The infrastructure layer for deploying agentic AI systems in production. Not the agents themselves β€” the platform that makes them reliable, fast, and observable at scale.

This sits at the emerging boundary between inference serving (get tokens out fast) and agentic orchestration (make reliable multi-step decisions). Most teams treat these separately. This project builds the bridge.

Problem Statement

Deploying a single LLM for generation is a solved problem. Deploying an agent that:

  • Makes tool calls with sub-second decision latency
  • Maintains state across multi-step reasoning chains
  • Fails gracefully when tools return unexpected results
  • Runs concurrently across hundreds of simultaneous sessions
  • Is observable enough that you can debug production failures

…is not solved. This project is building that infrastructure.

Key Technical Challenges

1. KV-Cache Management for Long Agent Sessions

Multi-step reasoning chains can span dozens of turns. Standard KV-cache strategies waste memory on completed reasoning steps. Solution: prefix caching + aggressive eviction for completed tool call branches.

2. Concurrent Session Isolation

100 simultaneous agent sessions shouldn’t interfere with each other’s state. Building session-isolated execution contexts with shared inference backend.

3. Tool Call Reliability

When an MCP tool returns an error, the agent needs to decide: retry, use fallback, or fail cleanly? Building a typed error taxonomy so agents can reason about failures.

4. Latency Budget Management

Each reasoning step has a time budget. If tool calls exceed it, the agent needs to degrade gracefully (use cached results, skip tool, etc.) rather than hang.

Benchmarks (Ongoing)
