Cline v3.89.0 Adds Claude Fable 5 Support, Fixes MiniMax M3 Thinking Controls
Cline, the AI-powered coding assistant, released v3.89.0 with support for Claude Fable 5 model integration. The update also fixes MiniMax M3 thinking controls across gateways and cleans up the Codex model list.
Cline v3.89.0 Adds Claude Fable 5 Support
Cline released version 3.89.0 on June 9, 2025, adding support for Anthropic's Claude Fable 5 model to its AI coding assistant platform.
What Changed
The update includes three key changes:
Added: Support for Claude Fable 5 model integration, allowing developers to use Anthropic's latest model through the Cline interface.
Fixed: MiniMax M3 thinking controls now work correctly across all gateways. The previous version had issues with MiniMax's chain-of-thought reasoning controls when accessed through different API endpoints.
Changed: Codex model list cleanup. The interface now presents a streamlined selection of available AI models, removing deprecated or redundant entries.
Technical Details
Cline is a VS Code extension that provides autonomous AI coding assistance. The platform supports multiple model providers, allowing developers to switch between different AI models based on their specific coding tasks.
The addition of Claude Fable 5 support expands Cline's model roster, which already includes models from OpenAI, Anthropic, Google, and Chinese AI labs including MiniMax.
The MiniMax M3 fix addresses a specific issue with the model's reasoning mode. MiniMax M3 includes a thinking process that can be toggled on or off, and the previous version of Cline had inconsistent behavior when accessing this model through different API gateways.
What This Means
This incremental update shows Cline's commitment to supporting the latest AI models as they become available. Claude Fable 5 support arrives within days of Anthropic's release, indicating close integration between coding assistant platforms and model providers.
The gateway-specific bug fix for MiniMax M3 highlights the complexity of managing multiple AI models through different API providers. As more companies offer model hosting and routing services, ensuring consistent behavior across gateways becomes critical for developer tools.
For developers using Cline, the update provides access to Anthropic's newest model while improving reliability for existing MiniMax users.
