Exponential backoff

As explained in AI Agents in Action, Second Edition

Exponential backoff is a retry scheduling technique that increases the waiting interval between successive attempts.

When a tool call fails because of a network timeout or rate limit, retrying immediately may add to the problem. Exponential backoff schedules retries with increasing waits between attempts. Add jitter—a little randomized variation—so failed agents do not all retry at the same instant. section 2.4.1 section 4.4.3

Place backoff inside a broader failure-handling plan:

  • Retry transient failures, but set a retry limit and surface a clear error when attempts are exhausted. section 4.1.3 section 4.4.3
  • Use structured errors, fallback paths, and timeouts where appropriate; backoff alone cannot fix every failed or hanging tool. section 2.4.1

A failed pipeline stage

If an agent stage hits a rate limit, wait before trying that stage again rather than restarting immediately. Increase the wait on later attempts, vary it with jitter, and report an error if the retry budget runs out. Retries cost time and tokens, so reserve them for failures they may resolve. section 4.1.3 section 4.4.3

How AI Agents in Action, Second Edition covers it

How deep it goes
Defines the practical waiting-and-jitter rule, but provides no backoff formula or implementation.
Examples
Uses network timeouts and rate limits as retry cases, alongside a bounded agent retry loop that does not implement backoff.
What it assumes
Assumes familiarity with failed tool calls or pipeline stages; explains the waiting-and-jitter idea without requiring retry mathematics.
What you can do after
Apply it to transient failures with jitter and bounded attempts, then surface an error if retries are exhausted.
How it connects
Connects retry budgets, sequential pipelines, rate limits, network failures, jitter, and error handling.
