The models and tools your developers already like
Aegis adds governance to the tools people chose for themselves, rather than replacing them
with one they did not.
Tools
- Claude Code
- Codex CLI
- Claude Desktop
- OpenAI SDKs
- aider
- anything OpenAI-compatible
Claude Code, Codex CLI and OpenAI-compatible clients are configured
automatically. Claude Desktop needs one import inside the app, no administrator. Cursor is
not supported yet. The ChatGPT desktop app cannot be pointed at Aegis
— it signs in with a ChatGPT account rather than as an API client, and no setting
changes that.
Governed models Tier 1

Prompts are inspected against the Aegis content policy before reaching the model, and blocked when they violate it. Model output is inspected the same way. Inspection is enforced by AWS in a separate account, so it cannot be turned off from the gateway. Prompt and completion content is not retained.
Zero data retention on Tier 1: the AWS account these models run in has
its data-retention mode locked to none in every operating region, enforced in an
account the gateway cannot edit.
Frontier OpenAI models Tier 2 — a different guarantee
- gpt-5.6-solfrontier
- gpt-5.6-terrafrontier
- gpt-5.6-lunafrontier
- gpt-5.5frontier
- gpt-5.4frontier
Prompts are inspected against the Aegis content policy before reaching the model, and blocked when they violate it. Inspection is enforced by the gateway rather than by AWS, and model output is not inspected on this path. AWS retains requests and responses for up to 30 days for safety and abuse prevention, and does not share them with the model provider. We retain no prompt or completion content.
The Frontier OpenAI models run on a separate AWS surface where the
enforcement that makes Tier 1 hold even against a compromised gateway does not exist, and
where AWS keeps requests for up to 30 days. Same inspection, weaker enforcement, real
retention — which is why Tier 2 is off by default and enabled per team by your
administrator, with its own description wherever it appears.
