## Decision facts: Aegis

- **Adopt for:** Aegis provides runtime policy enforcement for AI agents with cryptographic audit trails and human-in-the-loop approvals, supporting zero-code deployment switches suited for various compliance needs.

## Decision facts: mech-gov-framework

- **Requirements:** Requires Python version 3.10 or higher.; Optional installation of visualization and AWS Bedrock/SageMaker backend support for extended functionality.
- **Adopt for:** Mechanical Governance for LLM Decisions: Provides model-agnostic governance regimes and metrics for high-stakes decision systems involving large language models

## Choose when

### Choose Aegis if…

- Aegis is primarily TypeScript; mech-gov-framework is Python.
- License: Aegis is MIT, mech-gov-framework is Apache-2.0.
- Tags unique to Aegis: anthropic, audit-trail, llm-observability, policy-engine.
- Also covers AI Agents.
- Aegis ships Docker support for self-hosted deployment.
- You need cryptographic assurance of the audit trail to meet high-security standards.

### Choose mech-gov-framework if…

- mech-gov-framework is primarily Python; Aegis is TypeScript.
- License: mech-gov-framework is Apache-2.0, Aegis is MIT.
- Requirements: Requires Python version 3.10 or higher.; Optional installation of visualization and AWS Bedrock/SageMaker backend support for extended functionality..
- Tags unique to mech-gov-framework: ai-governance, decision-systems, learning-to-defer, llm-evaluation.
- When your application requires model-agnostic governance that supports multiple types of large language models, ensuring consistent compliance with regulatory and ethical standards.

## When NOT to use Aegis

- The project does not require a zero-code deployment switch and can manage changes directly in the codebase.
- Minimal regulatory requirements mean that elaborate configurations like Aegis's strict retention policies are unnecessary.

## When NOT to use mech-gov-framework

- If you have a preference for proprietary or closed-source frameworks that provide more tailored but less flexible control over model governance.
- When your project does not require extensive transparency or detailed monitoring capabilities, as this tool adds complexity and a learning curve specific to its unique features.
