What specific problem does this solve?

The Roo Code extension currently lacks support for the zai-org/GLM-4.5-Air model on the Chutes AI provider, which offers 151,329 token context window. This model performs on par with SOTA models.

Impact: All Roo Code users who need to process complex coding tasks.

Additional context (optional)

The zai-org/GLM-4.5-Air model offers:

151,329 token context window
106B total parameters with 12B activated
Free to use (no input/output pricing)

This model is particularly valuable for:

Complex reasoning tasks
