# Claude Duet

Proactive cloud agent that checks connected work apps, prepares tasks and asks for approval before consequential actions.

Canonical profile: https://ethicalstack.ai/products/claude-duet/

Scope: Claude Duet research preview for invited US Claude Pro or Max users. Uses the Claude account’s memory, connectors and plan limits; agent browser and computer run in Anthropic cloud.

Published overall: 2.7; 6/6 dimensions rated.

Round the equal-weight mean of available numerical ratings to one decimal; require at least four of six for an overall score. BDS status stays outside the mean; for eligible profiles, a boycott target caps the final score at 2/10 and a pressure target subtracts one point (minimum 1). Not listed and not checked do not adjust the score.

## Energy practices

Finding: 2/10

Assessment: https://ethicalstack.ai/products/claude-duet/#energy

Duet is described as an Anthropic cloud-computer and browser service; product-specific energy, facility electricity and resource-control reporting are absent.

Reason: 1 + 1 reporting + 0 electricity + 0 controls = 2/10. This grades documented practices and transparency.

Argument: Anthropic describes Duet’s dedicated hosted computer/browser, which establishes the product’s cloud operation. The reviewed docs do not quantify the service’s energy, identify electricity sourcing for the compute facility or offer workload resource controls tied to physical reductions; no impact is inferred.

Type: argument; confidence: medium

Scope (dimension): Claude Duet research preview for invited US Claude Pro or Max users. Uses the Claude account’s memory, connectors and plan limits; agent browser and computer run in Anthropic cloud.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Task energy, serving model route, region/facility electricity and compute resource controls are not reported for Duet.

## Training data

Finding: 2/10

Assessment: https://ethicalstack.ai/products/claude-duet/#training-rights

Duet names Claude Opus 5.5; Anthropic discloses broad training-data categories but not named sources, corpus rights or release-specific creator remedies.

Reason: 1 + 1 source transparency + 0 permission + 0 creator controls = 2/10, with the permission cap applied.

Argument: Anthropic’s Duet help page identifies Opus 5.5, whose Transparency Hub describes a proprietary mix of publicly available online information, public/private datasets, user data and synthetic data. It provides no named-source rights ledger; account training preferences are distinct from the corpus used to train the model.

Type: argument; confidence: medium

Scope (profile): Claude Duet research preview for invited US Claude Pro or Max users. Uses the Claude account’s memory, connectors and plan limits; agent browser and computer run in Anthropic cloud.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: No complete source/license inventory or Opus 5.5-specific evidence of creator removal and retraining was found in the reviewed disclosures.

## Your data & privacy

Finding: 5/10

Assessment: https://ethicalstack.ai/products/claude-duet/#privacy

Duet uses a cloud computer and connected Claude context; credentials are isolated from the agent, and memory/access can be reset or disconnected.

Reason: 5/10 reflects documented task approvals, isolated credentials and reset/disconnect controls, while the research preview remains cloud-hosted and inherits account-connected data.

Argument: Anthropic says Duet inherits Claude memory, skills and connected apps, stores task history and memory until deletion/reset, and runs its own cloud computer and browser. Its design keeps passwords and tokens outside the agent machine and adds an external approval/classifier layer, but this remains hosted processing.

Type: argument; confidence: medium

Scope (profile): Claude Duet research preview for invited US Claude Pro or Max users. Uses the Claude account’s memory, connectors and plan limits; agent browser and computer run in Anthropic cloud.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Retention periods, region-specific processing, model-training application and account controls follow Claude plan terms and the research-preview settings.

## Openness

Finding: 2/10

Assessment: https://ethicalstack.ai/products/claude-duet/#openness

Claude Duet is a closed hosted research preview using Claude Opus 5.5; no product runtime or model weights are published.

Reason: 2/10 reflects a managed, waitlisted cloud preview with a fixed model and no published source license or user-controlled deployment route.

Argument: Anthropic identifies Claude Opus 5.5 as the Duet model and describes a private cloud agent/browser architecture. The cited materials do not make the runtime or model weights available for inspection or self-hosting, although the product has connectors and user controls.

Type: argument; confidence: medium

Scope (profile): Claude Duet research preview for invited US Claude Pro or Max users. Uses the Claude account’s memory, connectors and plan limits; agent browser and computer run in Anthropic cloud.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: The service implementation and full model training record are not exposed in the cited launch materials.

## Worker protections

Finding: 2/10

Assessment: https://ethicalstack.ai/products/claude-duet/#labour

Anthropic publicly requires suppliers to follow a vendor code covering labor and human rights, but public worker-specific implementation, voice and outcomes are sparse.

Reason: 1 + 1 pay & conditions + 0 worker voice & remedy + 0 evidence & follow-through = 2/10. This grades documented worker safeguards, not a measured rate of mistreatment.

Argument: Anthropic’s July 2026 Transparency Hub says suppliers must comply with a Vendor Code of Conduct covering labor and human rights and apply equivalent standards through their own supply chains; the Trust Center lists a Global Vendor Code of Conduct, but its text is access-gated in the public interface. This supports limited credit for a supplier standard, not a finding about annotator pay, exposure controls or actual enforcement. This entry carries the same developer/operator finding to Claude Duet; it does not establish that this product was deployed under every cited relationship.

Type: argument; confidence: low

Scope (dimension): Anthropic: the documented developer/operator record, not proof of deployment of Claude Duet.

Research reviewed: 2026-10-24; evidence date: not recorded

Unknowns: The public code text, worker complaint outcomes, rates/pay, annotation supplier identities and workforce coverage were not accessible in this review; company model documentation does not establish current worker treatment.

## Military ties

Finding: 3/10

Assessment: https://ethicalstack.ai/products/claude-duet/#military-contracts

Anthropic reported extensive, mission-critical classified use in military and national-security workflows in February 2026, including intelligence analysis and operational planning, while the current contract status and any targeting/combat-intelligence use are not established.

Reason: 1 + 1 use restrictions + 1 enforcement & oversight + 2 relationship disclosure = 5, capped at 3/10. Known defense ties lower this rating; safeguards can improve it within the relationship’s cap.

Argument: Anthropic’s Feb. 26, 2026 statement says Claude was extensively deployed in classified Department of War and national-security settings for intelligence analysis, modeling and simulation, operational planning and cyber operations. The same statement says Anthropic had not objected to particular operations ad hoc and that lawful foreign-intelligence use was supported, while opposing mass domestic surveillance and fully autonomous weapons. This confirms broad defense enablement and named military workflow use, but does not identify target selection, strike decisions or combat-intelligence support. The statement reports the DoW was threatening offboarding; whether the deployment/contract continued by the October 2026 review date is not publicly established in the sources reviewed. This entry carries the same developer/operator finding to Claude Duet; it does not establish that this product was deployed under every cited relationship.

Type: argument; confidence: high

Scope (dimension): Anthropic: the documented developer/operator record, not proof of deployment of Claude Duet.

Research reviewed: 2026-10-24; evidence date: not recorded

Unknowns: The public statement does not enumerate active task orders, system versions, unit-level deployments, operational outcomes, or independent audit results. DoW supply-chain risk litigation and court orders make access status time-sensitive; the company's current page describes the status as of its stated dates.

## BDS targets

Finding: Not listed

Assessment: https://ethicalstack.ai/products/claude-duet/#israel-palestine

Anthropic is not named in the BNC consumer guide or No Tech campaign reviewed.

Reason: Campaign category, excluded from numerical scoring.

Argument: The official BNC guide and No Tech campaign list named corporate targets; Anthropic does not appear in the reviewed target lists. This limited check is not an endorsement and does not establish relationships with cloud or government customers.

Type: argument; confidence: medium

Scope (profile): Claude Duet research preview for invited US Claude Pro or Max users. Uses the Claude account’s memory, connectors and plan limits; agent browser and computer run in Anthropic cloud.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: This is limited to the two official BNC campaign sources; it does not cover every local campaign, supplier, investment, or future change.

- [BNC consumer boycott and pressure guide](https://bdsmovement.net/Guide-to-BDS-Boycott) (primary; checked not recorded)

- [BNC No Tech campaign](https://bdsmovement.net/no-tech-oppression-apartheid-or-genocide) (primary; checked not recorded)

## Reading the evidence

- Assessments are provisional editorial judgments. Cite the profile and the underlying sources, and retain confidence, scope and unknowns.

- Unknown, not-applicable and model-dependent are different states. Missing evidence does not establish good or bad conduct.

- Company-level evidence does not establish use of a particular product or model. Account plan, model, host and route can change an assessment.

- Energy scores describe documented practices and transparency, not measured request emissions. Zero component points can mean an evidence gap.

- Published overall scores require at least four of six numerical dimensions. Preserve coverage and BDS adjustments; BDS itself is categorical.

- No named BDS target found is limited to the reviewed campaign sources and is not approval. Personalized priorities do not change the published overall score.

- Review and source-check dates describe the research, not this deployment. Fetch current primary sources when the decision requires current verification.
