Synth Workshop · Stable 0.10.1

Increase your Experiments Per Minute

Download the Synth Workshop macOS app. Local models, ChatGPT login, direct provider APIs, and Synth API are all first-class paths into the same research loop.

Direct provider keys are billed by their providers and do not use your Synth allowance. Workshop labels Synth-backed cloud work separately and asks before starting paid compute.

Synth Workshop requires an Apple silicon Mac running macOS 14 or later with at least 16 GB of unified memory. Open this page on your Mac when you are ready to download.

Release envelopes

Choose the maturity level you intend to test

Stable is recommended. Beta, alpha, and dev retain their earlier versions and install beside it with separate bundle identities. All listed builds are ad-hoc signed and require the disclosed macOS first-launch approval.

After download

Open Workshop, then choose how you want to work

  1. 1. Extract and openVerify the checksum first. If blocked, approve only this app through Privacy & Security → Open Anyway.
  2. 2. Choose accessContinue locally without an account, or connect Synth for account-backed cloud models.
  3. 3. Verify before cloud workOnly start account-backed work after Workshop visibly confirms your plan and allowance.

A research referral does not install or launch that workflow automatically. Keep its starter prompt, then paste it into Workshop after the app is ready.

Build from source

One command after cloning

The build checks your toolchain, installs missing JavaScript dependencies, builds the macOS app, and emits an unnotarized ZIP, checksum, and manifest under dist/. No Synth credentials are required to compile it.

git clone --branch v0.10.1 --depth 1 https://github.com/synth-laboratories/workshop.git
cd workshop
./scripts/build.sh

Before you install

Requirements

  • macOS 14 or later on Apple silicon (M-series)
  • 16 GB unified memory minimum; 32 GB recommended for local models
  • Optional internet connection for ChatGPT login, direct provider APIs, Synth API, billing, and update checks
  • Enough local storage for any on-device model you choose to download

Version 0.10.1

Release notes

New

  • Session-local recovery for unsaved Report drafts.

Improved

  • Managed local MLX runtime identity and request compatibility.

Fixed

  • Persisted annotation reviews appear in Findings without changing sealed evidence.
  • Report save, navigation and sealing races retain newer edits.
  • Renderer failures offer a recovery path.

Privacy

  • Local model use runs on your Mac. When you choose a cloud model or hosted account feature, the necessary request is sent to that selected service.
  • Provider credentials remain in the native app's private storage rather than being handled by this download page.

Known limits

  • This app is ad-hoc signed and not Apple-notarized. Verify its checksum and approve only this app in macOS if prompted; do not disable Gatekeeper globally.
  • AI-backed acceptance and paid GEPA evaluation remain deferred; no new live-provider acceptance is claimed.
  • Updates are manual. The prebuilt app supports Apple Silicon and macOS 14 or later.

Support
