# Seedance

ByteDance Seed video-generation family delivered through Dreamina and developer/API routes; Seedance 2.5 is the newer Dreamina release.

Canonical profile: https://ethicalstack.ai/products/seedance/

Scope: Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Published overall: 2.8; 5/6 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: 3/10

Assessment: https://ethicalstack.ai/products/seedance/#energy

Seedance is offered through hosted Dreamina/API routes with user-selected output duration; no energy report or facility electricity mix is published in these launch sources.

Reason: 1 + 1 reporting + 0 electricity + 1 controls = 3/10. This grades documented practices and transparency.

Argument: The official model launch material documents duration and multimodal output settings, and the consumer article describes longer 2.5 clips. Those user controls set the requested output boundary but are not physical impact measurements or evidence of energy reductions.

Type: argument; confidence: medium

Scope (dimension): Seedance 2.x via Dreamina hosted consumer service or BytePlus API; routes have separate service policies.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Dreamina/API route region, task energy, facility electricity and resource use for selected model/duration are not disclosed in cited sources.

## Training data

Finding: 1/10

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

Seedance 2.0/2.5 launch pages describe model modalities and route but do not disclose training sources or rights.

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

Argument: ByteDance Seed and Dreamina identify Seedance releases and their multimodal functions, but the reviewed sources do not publish a named training corpus, source permissions or creator-removal pathway. Product-level safeguards and content provenance are separate from training-data permission.

Type: argument; confidence: medium

Scope (profile): Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Training corpus categories, source-level rights, release-specific creator controls and audit evidence remain unestablished in cited materials.

## Your data & privacy

Finding: Not enough evidence

Assessment: https://ethicalstack.ai/products/seedance/#privacy

Seedance model pages describe capabilities, not a unified privacy contract; Dreamina’s consumer route and BytePlus API must be checked under their own service terms.

Reason: No numeric privacy rating: official model-launch materials do not establish the service-specific data handling route for consumer versus API use.

Argument: ByteDance Seed identifies the current model family and developer entry points, while Dreamina announces consumer Seedance 2.5 rollout and its product safeguards. The reviewed pages do not establish one shared prompt retention or model-training policy for Dreamina and API users.

Type: argument; confidence: low

Scope (profile): Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Dreamina/CapCut and BytePlus service privacy terms, retention periods, regions and training defaults were not established from the cited model launch pages.

## Openness

Finding: 2/10

Assessment: https://ethicalstack.ai/products/seedance/#openness

Seedance 2.x is offered as a ByteDance model through product/API routes; no downloadable weights or self-host license were located in the reviewed sources.

Reason: 2/10 reflects official hosted product/API access and no reviewed open-weight or self-host deployment path.

Argument: Seed’s current Seedance product page links to try/API routes, and Dreamina presents 2.0/2.5 in its hosted creation product. The reviewed official sources do not establish open weights or customer-managed inference for Seedance.

Type: argument; confidence: medium

Scope (profile): Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: The absence claim is limited to these official pages; separate enterprise contracts could provide additional terms.

## Worker protections

Finding: 1/10

Assessment: https://ethicalstack.ai/products/seedance/#labour

Seed and Dreamina release pages cover model routes, product capabilities and safeguards, without publishing worker-condition or contractor disclosures for this model/service.

Reason: 1 + 0 + 0 + 0 = 1/10. Documented worker protections; missing disclosure is an evidence gap.

Argument: The reviewed Seedance and Dreamina launch sources describe video-model access, features and content safeguards. They do not report the relevant workforce’s pay, conditions, worker voice, content-moderation contractor protections or independent labour assurance; this is a specific disclosure gap.

Type: argument; confidence: medium

Scope (profile): Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Employee, contractor, annotation and moderation workforce conditions for ByteDance Seed / Dreamina remain unestablished in these public sources.

## Military ties

Finding: 7/10

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

No military relationship or product-specific military safeguards are established in the reviewed ByteDance Seed / Dreamina sources.

Reason: 7 base + 0 safeguard adjustment = 7/10 (0 of 9 safeguard points; every 3 adds 1). No military relationship was established in the cited sources. This ranks above known defense ties without claiming a verified clean record.

Argument: The official sources reviewed for Seedance describe its creative route, model access and user terms but do not establish defense work, a military customer, or binding operational restrictions. This product-level disclosure gap does not resolve unreviewed corporate or downstream relationships.

Type: argument; confidence: medium

Scope (profile): Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Company-wide defense customers and downstream uses of Seedance were not exhaustively established.

## BDS targets

Finding: Not listed

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

The company is not named in the two reviewed official BNC campaign sources.

Reason: Campaign category, excluded from numerical scoring.

Argument: This entry records only whether the named company appears in the BNC consumer guide or No Tech campaign. Not listed is a limited source check, not a finding of endorsement, compliance or absence of supplier and investment relationships.

Type: argument; confidence: medium

Scope (profile): Seed model capability pages and Dreamina consumer launch specify different model/access routes; rollout, terms and account eligibility attach to the chosen Dreamina or API service.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: The check does not cover every campaign, subsidiary, investor, supplier, local listing or future target change.

## 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.
