simulac 0.0.4

A CLI, library, and local server for interacting with the Tektonian backend.

Simulac

⚡️ Developer centric digital twin builder

---

Simulac is digital twin build tool filling the gap between physical world and software world.

Simulac helps transition between the two worlds, and provides developer-friendly API to building the world.

Quick start

Installation

Simulac requires Python 3.12 or later.

$ pip install simulac
$ uv add simulac

Sign up and create an API key

Remote benchmark execution requires a Tektonian API key. Go to our website and get an API key.

Store your API key with CLI commend:

simulac login

You can also provide the key through an environment variable:

export SIMULAC_API_KEY=<you_api_key>

Note: API keys can only be viewed once when created

Key function

Simulac provides one-line code execution for robot domain benchmark, and world building API (on developing)

Benchmark

You can execution famous Physical-AI benchmarks with one-line of code. We currently support:

• Libero
• Calvin
• Robomimic
• Metaworld

Visit benchmark list for details for running it.

Run benchmark

from simulac.gym_style import init_bench

env = init_bench(
    "Tektonian/Libero",
    "libero_90/KITCHEN_SCENE2_put_the_black_bowl_at_the_back_on_the_plate",
    0,
    {"control_mode": "OSC_POSE"},
)

step = env.step(ACTION_ARRAY)

Parallel Benchmark Execution

from simulac.gym_style import init_bench, make_vec

args = (
    "Tektonian/Libero",
    "libero_90/KITCHEN_SCENE2_put_the_black_bowl_at_the_back_on_the_plate",
    0,
)
options = {"benchmark_specific": {"control_mode": "OSC_POSE"}}

envs = [init_bench(*args, **options) for _ in range(3)]
vec_env = make_vec(envs)

steps = vec_env.step([[0.0] * 7 for _ in envs])
print(len(steps))

Configuration

Simulac reads configuration from environment variables when present:

• SIMULAC_API_KEY: use an API key without running simulac login
• SIMULAC_BASE_URL: override the default Tektonian API endpoint
• SIMULAC_LOG_LEVEL: set log verbosity. choose one of off, trace, debug, info, warning, error
• SIMULAC_TELEMETRY=off: disable telemetry

World building

The world-building surface is best viewed as an evolving foundation for scene assembly and engine integration.

Project Status

Simulac is currently alpha software.

• The remote benchmark client is the most complete public surface.
• Local world-building and runner APIs are still evolving.
