BYOA — Bring Your Own AI / API / computer / system

Hussh's architectural commitment. The user's keys, the user's models, the user's choice — Hussh provides the consent surface, not the AI vendor lock-in.

reference

TL;DR: BYOA stands for Bring Your Own AI / API / computer / system. It is Hussh's architectural commitment: the user picks the model, the API key, the device, the storage. Hussh ships the consent surface (PCHP) and the agent platform (One), not the AI vendor lock-in. BYOA is what makes Hussh ecosystem-neutral by design — the same property that lets PCHP credibly position as "SSL/TLS for the AI agent economy." Status as of 2026-05-04: Architectural invariant. Holds across every Hussh surface; not negotiable per-feature.

Relations

  • One — runs against BYOA models.
  • Kai, Nav — both are model-agnostic by commitment.
  • PCHP — consent at the data layer, not the model layer.
  • Three-layer architecture — BYOA is what keeps the Platform layer model-neutral.

The four "Y"s

  • Bring Your Own AI — the user (or their org) picks the model. Anthropic, OpenAI, Google, local Llama / Qwen, on-device, anything. Hussh runs against the model the user pays for.
  • Bring Your Own API — the user holds the key. Hussh holds keys to data; not keys to vendor APIs. If the user rotates their key, the user is in control.
  • Bring Your Own Computer — local-first where possible. On-device inference for sensitive context; cloud only when explicitly consented.
  • Bring Your Own System — the user's accounts (Gmail, Schwab, Plaid, calendar, photos) stay where they are. Hussh integrates; it does not migrate.

Why this matters strategically

The agentic-product market in 2026 is racing to lock users into a vendor's model. The pitch is convenience; the trap is lock-in. Hussh's bet is that consumers and enterprises both eventually want their data and their model choice to be independently portable. BYOA bakes that assumption into the architecture so it cannot drift.

This commitment is what makes PCHP credibly vendor-neutral consent infrastructure. A consent protocol owned by an AI vendor is just that vendor's TOS in a costume. PCHP can position as "SSL/TLS for the AI agent economy" only because the platform underneath does not care which model is on the other end.

What BYOA is not

  • Not "configure your own LLM endpoint." It's a guarantee that the user's choice is honored across every Hussh surface, with consent applied uniformly.
  • Not "we don't run any models." Hussh runs whatever the user authorizes; the user is the principal.
  • Not a feature flag. It is an architectural constraint applied at design time.

Sources

  • Three-layer architecture — where BYOA lives in the stack.
  • PCHP — consent is at the data layer, not the LLM layer.
  • One — the platform BYOA is implemented on.
