Allow Limiting Qwen CLI Provider Context Size in Roo Code #7598
Description
What specific problem does this solve?
Context:
The Qwen CLI provider currently defaults to a large context window size of 1 million tokens. However, in practice, when token usage exceeds approximately 200,000 tokens, tasks in Roo Code become very slow and tend to over-engineer outputs, negatively impacting performance.
Problem:
This very large context window causes inefficiency and delays during coding sessions using Qwen CLI.
Comparison:
When using the Qwen provider via OpenRouter with a default context window of 262,144 tokens, no such issues are observed.
Request:
Please add a setting or option in Roo Code to limit or cap the Qwen CLI provider context window size (e.g., 256k tokens). This would help maintain smoother performance and better task outputs.
