Copilot cloud agent model options and usage multipliers
The news at the time
GitHub added Claude Haiku 4.5 and GPT-5.4-mini as Copilot cloud agent model options. The notice frames them as options for simpler changes, not universal replacements for complex work.
The notice lists a 0.33x multiplier for each added model. A usage multiplier is not a measured guarantee of runtime, code quality or total project cost.
Follow-up checked during renewal
No additional follow-up fact was established in this renewal. This does not establish that nothing changed.
What to review before applying this
Evaluate representative tasks for correctness, retries and review effort alongside usage charges. Verify the current product model list and policies instead of treating this historical multiplier as a current price quotation.
