Capabilities

Everything your simulation practice needs, in one network.

From environment authoring to agent evaluation, sim-ai.net unifies the simulation lifecycle so your team can ship agents that actually behave.

Network-graph orchestration

Connect agents, environments and evaluators as a living graph. Re-route traffic, swap models and replay episodes without touching client code.

  • Topology-aware scheduling
  • Live hot-swap of agent variants
  • Distributed deterministic replay

Agent eval, side-by-side

Run head-to-head evaluations across hundreds of episodes. Slice by scenario, behavior tree, or reward shape — in seconds, not sprints.

  • Matrix evaluation runners
  • Behavioral diff viewer
  • Statistical significance built-in

Shared simulation registry

A network registry of community and private environments. Cite, fork, and remix — with cryptographic provenance and granular access.

  • Public & private namespaces
  • Forks with diff trails
  • SBOM for every environment

Realtime telemetry

Stream metrics, traces and tool-calls from every running episode. Drill into a single decision step or zoom out to fleet-wide health.

  • 1ms event resolution
  • OpenTelemetry compatible
  • Episode-aware traces

Enterprise-grade security

SOC2 Type II, SAML SSO, BYOK, audit logs and a self-hostable control plane. Your simulations never leave your perimeter unless you allow it.

  • SAML / SCIM out of the box
  • Bring-your-own-key encryption
  • Region-pinned data residency
Platform

A clean SDK for the messy reality of simulation.

One client, one network, one mental model. Spin up an environment, attach an agent, and observe the run from any language. The orchestrator handles topology, retries, and snapshotting.

  • Polyglot SDKs — Python, TypeScript, Rust, Go.
  • Deterministic seeding across distributed runs.
  • Snapshots and time-travel for any episode.
  • Webhook + gRPC streaming surfaces.

The Network

A connected fabric, not a pile of notebooks.

Every team on sim-ai.net contributes to a shared substrate of environments, evaluators, and agent variants — with private rooms when you need them.

01

Discover

Browse a curated registry of simulation environments and agent recipes published by your peers.

02

Compose

Snap environments, agents and evaluators together as a graph. Compose first, configure later.

03

Calibrate

Pipe in real telemetry to close the sim-to-real gap. Track fidelity scores over time.

04

Ship

Promote variants through staging rings with policy gates and reproducible attestations.
