fix(compression): remove hardcoded gemini-3-flash-preview as default summary model#2464
Conversation
…summary model Closes #2453 The DEFAULT_CONFIG was hardcoding google/gemini-3-flash-preview as the summary_model for context compression. This caused unexpected OpenRouter charges for users who configured a different provider/model, because the compression task would silently fall back to gemini via OpenRouter even when the user's main model was on a different provider. Fix: change summary_model default to empty string. When empty, call_llm() resolves the model through the standard auto-detection chain (auxiliary.compression config -> env vars -> main provider), which correctly uses the user's configured provider and model. Users who want a dedicated cheap model for compression can still explicitly set compression.summary_model in their config.yaml.

Salvage of PR #2457 by @Mibayy. Fixes #2453.
The default config hardcoded
google/gemini-3-flash-previewas the compression summary model, causing unexpected OpenRouter charges for users on other providers. Now defaults to empty string, which falls through to the user's configured main model.Users who want a dedicated cheap model can still set it explicitly in config.yaml.
