Frequently Asked Questions

Can OpenClaw forward messages to a webhook without LLM interference?

Yes. Using the `before_dispatch` hook, OpenClaw can selectively forward inbound messages (e.g., from WhatsApp) to an external webhook while skipping agent dispatch entirely.

Why does oMLX suffer from context thrashing?

oMLX currently lacks Flash Attention support, causing inefficient attention computation and memory bloat during long sessions, especially with large models like Qwen3.6-27B-mxfp8.

Does Ollama support model switching mid-session?

Yes, but without context sanitization logic for reasoning traces, which OpenClaw aims to solve (though currently has a bug in version 2026.5.5).
