Stop Conditions

Prevent infinite loops and enforce predictable completion behavior.

Configuring Stop Rules

TypeScript

const result = await client.callModel({
  model,
  input,
  stop: {
    max_steps: 6,
    stop_sequences: ["END_PLAN"],
    require_final_text: true,
  },
});

Stop Object

Name	Type	Description
max_steps	integer	Maximum turns including tool iterations.
stop_sequences	string[]	Sequences that terminate generation.
require_final_text	boolean	Require plain-text assistant output before stop.
timeout_ms	integer	Time budget for the whole run.

Defensive Defaults

stop-defaults.ts

const DEFAULT_STOP = {
  max_steps: 8,
  timeout_ms: 25_000,
  require_final_text: true,
};

Latency budgeting

Always set an overall timeout for user-facing requests to avoid hanging interfaces.
