01 Request
Understand the work
Complexity, recent tool context, code, security, and other risk signals can keep the requested model in place.
Intelligent routing, deliberately constrained
Use a more efficient model only when the work earns it.
CutCtx routing is opt-in. It keeps the requested model when the work is high-risk, ambiguous, tool-heavy, capability-incompatible, or not proven safe for the active provider, account, and transport.
Conservative by default · Observable decision reasons · No silent provider switch
A safe decision path
The route has to prove itself.
CutCtx does not treat a short prompt as automatically safe to downgrade. The request, available target, and transport must all satisfy the policy before a route can apply.
02 Capabilities
Match the contract
Tool calling, structured output, vision, audio, streaming, and other required capabilities must be supported by the target.
03 Transport
Prove the path
Provider, account, and transport proof constrain which targets can be considered.
04 Readiness
Require eligibility
Readiness, certification, availability, and cost gates keep unknown or unsuitable candidates out.
05 Outcome
Route or retain
A route applies only when every gate passes. Otherwise, the requested model retained outcome is the correct result.
What the operator can inspect
See the decision, not just the effective model.
Routing evidence identifies an applied source-to-target pair or a clear retention reason such as no route, insufficient confidence, unsuitable workload, or missing capabilities.
Illustrative routing receiptRead-only evidence
Eligible route applied
Only after complexity, capability, provider, account, transport, readiness, and certification gates pass.
requested model retained
Used when a route is not warranted; no fallback is used to bypass a rejected safety condition.
Reason available
Examples include no_route_for_model, confidence_below_threshold, and workload_not_downgradeable.
Verified preset language
Start with a conservative preset, not a blanket downgrade.
Canonical preset
codex-gpt54mini-high
The primary named preset for the documented conservative routing behavior.
Compatibility aliases
codex-opencode-slim
oh-my-opencode-slim
Compatibility aliases, not separate products or routing plans.
Operator control
Opt in, inspect, decide.
Routing status is read-only. It does not silently change providers, accounts, credentials, transports, or models.
