Package gemini implements thinking configuration for Gemini models.

Gemini models have two formats:

Gemini 2.5: Uses thinkingBudget (numeric)
Gemini 3.x: Uses thinkingLevel (string: minimal/low/medium/high) or thinkingBudget=-1 for auto/dynamic mode

Output format is determined by ThinkingConfig.Mode and ThinkingSupport.Levels:

type Applier struct{}

Applier applies thinking configuration for Gemini models.

Gemini-specific behavior:

func NewApplier() *Applier

NewApplier creates a new Gemini thinking applier.

func (a *Applier) Apply(body []byte, config thinking.ThinkingConfig, modelInfo *registry.ModelInfo) ([]byte, error)

Apply applies thinking configuration to Gemini request body.

Expected output format (Gemini 2.5):

{
  "generationConfig": {
    "thinkingConfig": {
      "thinkingBudget": 8192,
      "includeThoughts": true
    }
  }
}

Expected output format (Gemini 3.x):

{
  "generationConfig": {
    "thinkingConfig": {
      "thinkingLevel": "high",
      "includeThoughts": true
    }
  }
}
