}Reset complexity analyzer config
Restores the built-in reference phrase lists and hot-reloads the routing plugin. The selected classifier, decision-model settings, semantic and LLM configuration, and session settings are preserved.

Authorizations
Management API authentication for /api/* endpoints. Use the Authorization header
with Bearer <token>, where <token> is one of:
- a Bifrost management API key,
- a dashboard session token issued by
POST /api/session/login, - base64 of
<admin-username>:<admin-password>(legacy equivalent ofBasicAuth).
Virtual keys (sk-bf-*) and the x-api-key header are not accepted on management APIs -
the sole exception is GET /api/governance/virtual-keys/quota, which is virtual-key-only.
Authentication alone is not sufficient in Bifrost Enterprise: each operation page shows a
Required Permissions table (Resource:Operation, for example Dashboard:View) above
its Authorizations section, and the caller's RBAC role or management API key scopes must
include what it lists, otherwise the request is rejected with 403 Forbidden.
A local admin — authenticated with the admin password, or any caller on a deployment with dashboard auth disabled — bypasses these checks and can call every management endpoint.
OSS setup lock. On Bifrost OSS, while dashboard auth is not active (no admin account,
or auth disabled), every management endpoint except the public ones (/health,
/api/version, /api/session/is-auth-enabled, /api/session/login, ...) requires the
operator's setup token in the X-Bifrost-Setup-Token header, in place of Authorization.
The token is set with setup_token in config.json or the BIFROST_SETUP_TOKEN
environment variable. A missing header returns 401, a wrong token 403. The header
stops working once dashboard auth is enabled. The dashboard instead trades the token once
for an HttpOnly bifrost_setup_session cookie via POST /api/session/setup.
See Required permissions for how
permissions are derived and which endpoints are exempt.
Response
Complexity analyzer config reset successfully
Full runtime configuration for complexity routing analysis.
Reference phrases for semantic complexity classification, one list per tier. Each request is embedded and takes the tier of its nearest phrase. Entries should be whole example prompts rather than individual keywords. Each phrase is limited to 2000 characters, the normalized lists may contain at most 750 phrases combined, and the same phrase cannot appear in two tiers. The field names predate semantic classification and are kept for backward compatibility.

Deprecated score thresholds for the retired lexical complexity classifier. This block is optional and ignored by semantic classification, but remains accepted for backward compatibility. When supplied, values must satisfy 0 < simple_medium < medium_complex < 1.

Chat-completion (LLM) fallback classifier settings. The block is inert

semantic classification produces no tier. Tier names (SIMPLE, MEDIUM,
COMPLEX) and the response format are fixed: the gateway always appends a
non-editable reinforcement stating them.

Session-aware complexity routing. When enabled and a supported session identity is present, Bifrost retains the highest tier observed across normally sequential turns for 24 hours of inactivity. It uses the configured primary classifier and is independent of provider session stickiness.
