dsperse 3.8.2

Distributed zkML Toolkit

DSperse: Community Edition

DSperse is a proving-system-agnostic intelligent slicer for verifiable AI. It decomposes ONNX neural network models into circuit-compatible segments and orchestrates compilation, inference, proving, and verification across pluggable ZK backends.

Features

• Model Slicing: Split neural network models into individual layers or custom segments
• ONNX Support: Slice and orchestrate ONNX models
• Layered Inference: Run inference on sliced models, chaining the output of each segment
• Zero-Knowledge Proofs: Generate and verify proofs for model execution via JSTprove
• Tiling and Channel Splitting: Automatically decompose large convolutions for circuit-compatible execution
• Proof System Agnostic: Pluggable backend architecture supporting Expander and Remainder proof systems

Documentation

• Overview: High-level overview of the project, its goals, and features
• JSTprove Backend: JSTprove integration and usage

Installation

From PyPI (includes CLI)

pip install dsperse

This installs both the dsperse CLI command and the Python library bindings. No additional dependencies required — everything is compiled into a single native extension.

From source (Rust binary)

cargo install --path crates/dsperse

As a Rust library

[dependencies]
dsperse = { git = "https://github.com/inference-labs-inc/dsperse.git" }

CLI Usage

DSperse provides six subcommands that form a complete pipeline:

Command	Description
slice	Split an ONNX model into segments
compile	Compile slices into ZK circuits
run	Execute chained inference across slices (--weights to inject consumer ONNX)
prove	Generate ZK proofs for a completed run
verify	Verify ZK proofs
full-run	Execute compile, run, prove, verify in sequence (supports --weights)

Quickstart

dsperse slice --model-dir models/net
dsperse compile --model-dir models/net --parallel 4
dsperse run --model-dir models/net --input-file models/net/input.json
dsperse prove --model-dir models/net --run-dir models/net/run/run_*
dsperse verify --model-dir models/net --run-dir models/net/run/run_*

Or run the entire pipeline at once:

dsperse full-run --model-dir models/net --input-file models/net/input.json

To inject consumer weights from a fine-tuned ONNX model (same architecture, different weights):

dsperse run --model-dir models/net --input-file models/net/input.json --weights path/to/consumer.onnx
dsperse full-run --model-dir models/net --input-file models/net/input.json --weights path/to/consumer.onnx

Python Library Usage

import dsperse

metadata_json = dsperse.slice_model("models/net/model.onnx", output_dir="models/net/slices")
dsperse.compile_slices("models/net/slices", parallel=4)
run_json = dsperse.run_inference("models/net/slices", "models/net/input.json", "models/net/run")
proof_json = dsperse.prove_run("models/net/run", "models/net/slices")
verify_json = dsperse.verify_run("models/net/run", "models/net/slices")

To inject consumer weights at inference time, pass weights_onnx (path to a fine-tuned ONNX with the same architecture):

run_json = dsperse.run_inference(
    "models/net/slices", "models/net/input.json", "models/net/run",
    weights_onnx="path/to/consumer.onnx",
)

slice_model, run_inference, prove_run, and verify_run return JSON strings parseable with json.loads(). compile_slices returns None.
