To use Claude Cowork with abliteration.ai, configure Claude Desktop’s third-party inference mode with inferenceProvider: gateway and inferenceGatewayBaseUrl: https://api.abliteration.ai. Once configured, every Cowork and Claude Code Desktop session routes through abliteration; Anthropic never sees prompts or completions. The same Claude Desktop binary runs both standard and 3P modes — the managed configuration profile activates 3P.

​
Requirements

​
Configuration keys

Cowork reads its configuration once at launch. Quit and relaunch after any change.

​
Setup via the in-app UI

For a single device or to generate a profile for fleet rollout:
  1. Open Claude Desktop. Help → Troubleshooting → Enable Developer Mode.
  2. Developer → Configure third-party inference.
  3. Select Gateway, enter the values from the table above, save.
  4. Use Export to write .mobileconfig (macOS) or .reg (Windows) for distribution.

​
Setup via MDM

Push the same keys directly to the OS preference store.

​
macOS

Domain: com.anthropic.claudefordesktop. Deliver via Jamf, Kandji, Mosyle, or any MDM that supports App Configuration.
Array-typed keys must be a <string> containing a JSON array, not a native plist <array>:

​
Windows

Registry path: HKCU\SOFTWARE\Policies\Claude (per-user) or HKLM\SOFTWARE\Policies\Claude (machine-wide). Deliver via Group Policy, Intune, or any MDM that supports .reg files.

​
Authentication

Both are accepted on /v1/messages. For environments that disallow static keys, point inferenceCredentialHelper at an executable that prints a short-lived credential to stdout (TTL via inferenceCredentialHelperTtlSec, default 3600 s).

​
Models

When inferenceModels is unset, Cowork populates the picker from GET /v1/models. Today that surfaces abliterated-model. To pin explicitly:
The first entry is the default.

​
Verifying the install

Launch Claude Desktop on a test machine. You should see:
  • Cowork and Code tabs in the left navigation
  • No Chat tab
  • A Gateway sign-in option
If users see an error at launch, check that inferenceProvider is set and that the gateway key is valid. macOS console logs and Windows Event Viewer surface deeper errors.

​
Per-user policy

Cowork’s blanket usage caps (inferenceMaxTokensPerWindow, inferenceTokenWindowHours) apply per device. For different policies by team, issue project-scoped keys for the relevant projects. Published policies scoped to a project apply to its Cowork traffic. See Policies.

​
Data handling

Inference traffic terminates at abliteration.ai — Anthropic never sees prompts, completions, or tool inputs. Telemetry to Anthropic is metadata only (token counts, error diagnostics) and can be disabled with disableEssentialTelemetry and disableNonessentialTelemetry. See Policy data and access for policy decision data.
