Tool call with dates fails

Could this be some template issue?..
My parameters (temp. etc.) are Google recommended. I tried various quantization levels.
I am using MCP server with a lot of tools. All read-only MCP tools work fine. When model invokes create_time_session which involves a date or a datetime, it passed this JSON to a tool:

{
  "end_time": "<|\"|>2026-03-23T16:00:00<|\"|>",
  "start_time": "<|\"|>2026-03-23T14:00:00<|\"|>",
  "task_id": 59
}
  • <|\"|> tokens don't belong there.

For example, Qwen3.5 35B-A3B / 27B call that MCP server correctly.

We reconverted the GGUFs using the latest llama.cpp. Hopefully it fixes your issue, lemme know if it doesn't.
