Release Notes: v0.7.0¶

Release Date: 2026-07-05

Highlights¶

Thinking Configuration: Native Gemini thinking level support with ThinkingConfig
Cross-Provider Reasoning: ReasoningEffort and ThinkingType mapping to Gemini levels

New Features¶

ThinkingConfig¶

Native support for Gemini's thinking/reasoning configuration:

import "github.com/plexusone/omni-google/omnillm"

level := omnillm.ThinkingLevelHigh
budget := int32(8192)
req := &omnillm.Request{
    Model: "gemini-2.0-flash-thinking-exp",
    ThinkingConfig: &omnillm.ThinkingConfig{
        ThinkingLevel:  &level,
        ThinkingBudget: &budget,
    },
    Messages: messages,
}

ThinkingLevel Constants¶

Constant	Value	Description
`ThinkingLevelMinimal`	`"MINIMAL"`	Minimal thinking
`ThinkingLevelLow`	`"LOW"`	Low thinking effort
`ThinkingLevelMedium`	`"MEDIUM"`	Medium thinking effort
`ThinkingLevelHigh`	`"HIGH"`	High thinking effort

Cross-Provider ReasoningEffort¶

Use the unified ReasoningEffort field via the OmniLLM provider interface:

import (
    omnillm "github.com/plexusone/omnillm-core"
    _ "github.com/plexusone/omni-google/omnillm"
)

effort := omnillm.ReasoningEffortHigh
resp, err := provider.CreateChatCompletion(ctx, &omnillm.ChatCompletionRequest{
    Model:           "gemini-2.0-flash-thinking-exp",
    ReasoningEffort: &effort,
    Messages:        messages,
})

ReasoningEffort Mapping¶

ReasoningEffort	Gemini ThinkingLevel
`none`	MINIMAL
`low`	LOW
`medium`	MEDIUM
`high`	HIGH

ThinkingType Mapping¶

ThinkingType	Gemini ThinkingLevel
`enabled`	HIGH
`disabled`	MINIMAL
`adaptive`	MEDIUM

Tests¶

Unit tests for thinking config conversion
Tests for ReasoningEffort to ThinkingLevel mapping
Tests for ThinkingType to ThinkingLevel mapping
Budget token conversion tests

Dependencies¶

github.com/plexusone/omnillm-core v0.17.0 → v0.18.0

Installation¶
