Proper config shared by badtheorylabs so you dont run in zombie loops
binary: /home/bfg/applications/llama.cpp/build/bin/llama-server
model: BTL-4-IQ2_XXS.gguf
mmproj: removed. Compact is a text-only build with no vision tower, and that
projector was for Qwen3.6 anyway. BTL-4 is qwen3_5_moe.
chat_template: removed. The GGUF ships the correct one. BTL-4 uses a
<function=name><parameter=x> DSL, not stock Qwen's JSON form.
host: 0.0.0.0
port: 8080
ui: false
Use the GGUF's embedded Jinja template. Without this, llama.cpp falls back to
its legacy built-in templates and BTL-4's tool-call format is never used, so
removing the chat_template override above only helps if this is on.
jinja: true
Separate reasoning into reasoning_content instead of letting it accumulate
into content every turn. llama.cpp's default "auto" does not do this
correctly for BTL-4.
reasoning_format: deepseek
threads: 6
threads_batch: 6
ubatch_size: 2048
batch_size: 2048
gpu_layers: 99
flash_attention: "on"
parallel: 1
250000 was costing you KV
This is the config. Use this.
Thank youuu ❤️
so what's the context limit not to run into zombie loops? I hit a bunch so far, and for me it's not yet clear how much context it supports before acquiring alzheimer
it has 262k context
