Dagster vs. Tenet AI: Pipeline Lineage vs. Decision Provenance
Dagster tracks which assets a pipeline touched and what ran. Tenet tracks why the AI agent inside that pipeline made each specific business decision. They answer different compliance questions — here's when you need each.
The Compliance Questions Dagster Answers
Dagster answers specific compliance questions about data pipelines. It tracks data lineage as it moves through processes, showing what data was accessed, altered, or generated during each pipeline run. This matters for regulations like GDPR and CCPA, which require organizations to document how they handle personal data. For example, a financial institution running a risk assessment model needs to prove during audit that customer data was processed lawfully. Dagster traces which datasets the model used, creating the documentation required by GDPR Article 30, which mandates records of processing activities.
The Compliance Questions Tenet Answers
When it comes to compliance, AI systems must provide transparency about decision-making, not just operational tracking. Dagster excels at tracing pipeline assets and showing what data was processed and when. This matters for data integrity verification, but it doesn't explain why an AI agent chose one decision path over another. Tenet AI addresses that gap. For compliance teams in fintech or healthtech navigating GDPR or the Fair Credit Reporting Act (FCRA), understanding the rationale behind AI decisions is mandatory. Consider a loan application processed by an AI agent. A compliance officer needs more than confirmation that the application was reviewed—they need to know why it was approved or denied.
Side-by-Side: Dagster vs. Tenet AI
Dagster and Tenet AI solve different compliance problems. Dagster tracks pipeline lineage, showing which assets were involved and what steps executed during data processing. This matters for GDPR Article 30 compliance, which requires organizations to document their processing activities. Tenet AI captures decision provenance—the reasoning behind each AI decision. This becomes critical in sectors where decisions must be justified and audited, like finance and healthcare. Under the EU's AI Act, high-risk AI systems must produce auditable records. Tenet AI provides a cryptographic audit trail that documents decision context and reasoning. A fintech approving loans illustrates the difference.
Why Teams Use Both: Layered Compliance
In compliance, knowing what happened differs from understanding why it happened. Organizations use both Dagster and Tenet AI to address these distinct requirements. Dagster tracks the execution lineage of data pipelines and answers the "what": which assets were involved and what processes ran. This matters for audits focused on data integrity and traceability, often required by regulations like GDPR Article 30, which mandates records of processing activities. Tenet AI addresses the "why" behind decisions made by AI agents. For compliance teams dealing with LLM-based AI in sectors like fintech or healthtech, understanding the rationale behind each decision is essential.
How to Add Tenet to Your Dagster Pipeline
Integrating Tenet AI into your Dagster pipeline adds decision provenance to your operational lineage. Dagster tracks what your pipeline touched and what ran. Tenet records why your AI agent made each specific decision. To start, you need the Ghost SDK, which captures the decision context of your AI models. Call \`ghost.capture()\` within your AI agent's code to create an immutable record of each decision. This record includes the reasoning, confidence levels, inputs, and outputs—details that compliance teams need to verify adherence to regulations like GDPR (Articles 13-14 on right to explanation) or HIPAA's audit trail requirements. Consider a credit approval system. Every decision to approve or reject an application gets recorded with all relevant details.
