Breaking Changes

●Issue #1

The common parameter `reasoning_budget_message` has been moved into the sampling parameters configuration.

●Issue #2

The common parameter `reasoning_budget` has been removed; users should now standardize on using `reasoning_budget_tokens` within the sampling configuration.

Migration Steps

  1. 1
    If you were using `reasoning_budget_message`, move its configuration to the sampling parameters.
  2. 2
    If you were using the common parameter `reasoning_budget`, replace its usage with `reasoning_budget_tokens` in the sampling configuration.

Release Summary

This release refactors sampler parameters by moving `reasoning_budget_message` into the sampling configuration and standardizing on `reasoning_budget_tokens` while removing the deprecated common parameter `reasoning_budget`.
