Code Assistant inference

Code assistants propose, explain, or modify software. Their inference cost should be assessed alongside whether the change satisfies the task and passes the project’s checks.

What does this workflow do?

Code assistants propose, explain, or modify software. Their inference cost should be assessed alongside whether the change satisfies the task and passes the project’s checks.

01Deep dive

Design the workflow before choosing a model

Separate repository search, planning, editing, and validation. Give editing tools access only to the intended workspace and capture the diff alongside test results.

Define a representative input and an explicit acceptance criterion. Keep model and prompt versions with the result so quality changes can be investigated.

02Deep dive

Evaluate outcomes and failure modes

Measure task completion, test outcomes, regressions, and reviewer correction time.

Use representative repository tasks with known acceptance criteria. Include ambiguous requirements, failing tests, unfamiliar dependencies, and changes spanning several files.

Compare candidate routes on the same held-out examples. Report how many examples were evaluated and inspect failures rather than relying on a single average score.

03Deep dive

Roll out with a measurable cost baseline

Use a reviewed patch as the initial output. Expand autonomy only after measuring failures and establishing an approval boundary for releases and other consequential actions.

Calculate cost per accepted outcome using input and output tokens, retrieval or tool fees, retries, and review effort. A lower token price is useful only if the total workflow still meets its requirements.

o10 can provide model routing for the inference steps. Your application remains responsible for workflow permissions, tool behavior, and deciding whether the final result is acceptable.

FAQFrequently asked questions

Common questions

What should be measured before changing the route?

Record the current workflow’s outcome quality, latency distribution, failure rate, and fully loaded cost. Compare the candidate on the same tasks and include failed attempts and retries.

Are the savings figures on this site guaranteed?

No. Calculator inputs and workload examples are illustrative. Establish your own baseline and measure the candidate under comparable conditions before projecting savings.
