Energy practices

4/10↑

Perplexity lets users choose models and switch between standard and deeper Pro Search modes; models can come from multiple upstream providers. Consumer-query energy, emissions, water, and power sourcing are not reported.

See the evidence

Official help material shows Pro Search can use several upstream models and multiple web-search steps, while standard search is faster and less deep. This supports a variable host boundary and user workload controls, not a footprint. Since providers and regions vary, a provider’s company-wide renewable claim cannot be assigned to Perplexity queries. No actual impact is measured.

1 + 1 reporting + 0 electricity + 2 controls = 4/10. This grade covers documented practices and transparency; it does not measure the energy or emissions of a request.

Actual provider/model per query, serving region and facility; request energy/water/emissions; power sourcing at each upstream provider; physical effects of standard vs. Pro Search.

Reporting1/3: Perplexity documents model choices and third-party providers, establishing a variable upstream route; no consumer-query energy/carbon/water quantities are published.
Electricity sourcing0/3: No fixed provider/region route or Perplexity electricity mix is established; upstream models and providers vary by query and user setting.
Resource controls2/3: Users can choose among models and standard vs. Pro Search/research modes. These modes provide workload-depth choices, but no energy reduction is measured.

Water disclosure

Water reporting has not been assessed for this choice.

Training data

—Depends on the model↑

Perplexity identifies a Sonar base model in its third-party-model disclosures, while the service also offers other model routes. One named component cannot establish rights for the full product.

See the evidence

A service-wide grade would overgeneralize from one Sonar model to other available models and configurations. Assess Sonar or another exact model separately if the profile is narrowed.

The actual model route for a query and the training data for Perplexity’s fine-tuned components require separate model-specific evidence.

Third-Party Models & Terms ↗

Your data & privacy

4/10↑

For Free, Pro and Max consumer users, Perplexity says AI Data Retention (AI training data collection) is enabled by default. Users can opt out, but that only applies to future collection; previously collected training data cannot be removed. Data may still be processed for service operation, legal compliance and product improvement.

See the evidence

The consumer default allows AI-training data collection, with a user-level opt-out that is prospective only. The policy also retains operational, legal and product-improvement processing after opt-out. This supports a limited score for published controls with material limits, not a strong privacy score.

Data Collection at Perplexity ↗

Openness

3/10↑

Perplexity is a hosted search assistant that can use different third-party models depending on plan, query and settings. Its terms say Sonar is based on Meta Llama 3.1 70B but fine-tuned and operated by Perplexity; that does not make Perplexity’s search and serving stack locally reproducible.

See the evidence

The documented open-weight base model is a limited public component, while fine-tuning, the product pipeline and other provider models remain distinct and hosted. Perplexity does not document a full self-hostable stack.

Worker protections

1/10↑

Perplexity lists third-party providers and says a request may use some, all, or none of them depending on plan and settings; it also says Sonar is fine-tuned and operated by Perplexity.

See the evidence

Perplexity lists third-party providers and says a request may use some, all, or none of them depending on plan and settings; it also says Sonar is fine-tuned and operated by Perplexity. These route disclosures do not report data-worker pay, safety protections, vendor conditions, or independent labor outcomes for Perplexity’s own or upstream work.

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

Worker pay, exposure and health protections, paid versus volunteer roles, vendor/subcontractor coverage, grievance routes, and independent outcome checks are not established by the reviewed third-party model terms and government product pages checked; per-query model routing and provider workforce conditions remain configuration-specific and undisclosed.

Pay & conditions0/3: No opened source reports worker pay, hours, exposure protections, contractor coverage, or worker-level outcomes for Perplexity. The reviewed material is limited to Third-party model terms and government product pages checked; per-query model routing and provider workforce conditions remain configuration-specific and undisclosed.; its silence is an information gap, not evidence of poor conditions.
Worker voice & remedy0/3: The reviewed material for Perplexity doesn’t show worker representation, grievance access, bargaining voice, or documented remedies. Public code contributions, customer controls, or creator rights do not demonstrate worker voice across employees and suppliers.
Evidence & follow-through0/3: No reviewed source provides an independent audit or corroborated worker-level outcomes for Perplexity’s relevant employees, contractors, and data-work suppliers. The available disclosures are company/project materials rather than independent labor verification.

Military ties

8/10Civilian government work↑

Perplexity has a GSA OneGov agreement for federal agencies; consumer terms prohibit violent content but do not expressly bar military, intelligence or weapons uses.

See the evidence

GSA announced a direct OneGov agreement making Perplexity Enterprise Pro for Government available to federal agencies at a stated 18-month price, and Perplexity’s government offering emphasizes cited research/drafting and agency-system connections. Its consumer Terms prohibit excessively violent content and promoting/facilitating violence, but don’t confirm a blanket military, weapons or intelligence-use ban; no military deployment was established.

7 base + 1 safeguard adjustment = 8/10 (4 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.

The reviewed record doesn’t show all current contracts, subcontractors, deployment configurations, actual use by end users, or contract enforcement outcomes. For downloadable/open releases, company-hosted terms do not bind independent downstream deployments.

Use restrictions1/4: Consumer terms prohibit excessively violent content and using services to incite, organize, promote or facilitate violence; there is no explicit military/intelligence or weapons purpose ban and Enterprise/API scope may use separate terms.
Enforcement & oversight1/3: Consumer terms permit ordinary account removal/termination and GSA enterprise acquisition uses security/procurement conditions, but no military-specific enforcement review or remedy is disclosed.
Relationship disclosure2/2: GSA publishes the named agreement, price and term and Perplexity names government research/drafting use; actual agency deployment and outcomes are not detailed.

GSA announced a direct OneGov agreement making Perplexity Enterprise Pro for Government available to federal agencies at a stated 18-month price, and Perplexity’s government offering emphasizes cited research/drafting and agency-system connections. These establish civilian federal procurement availability; no military customer, intelligence mission or operational deployment was established in the reviewed sources.
