Frequently asked questions
What kind of model is bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF?
bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF is a code-focused language model with 34.66 billion parameters, based on the qwen35moe architecture. It is released under the apache-2.0 license and distributed as GGUF files for local inference.
How much VRAM do you need to run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF?
You need about 1.06 GB of VRAM to run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF entirely on the GPU using the GGUF quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF on an 8 GB GPU?
Yes. With 8 GB of VRAM you can run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF fully on the GPU using GGUF (about 1.06 GB).
Can I run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF fully on the GPU using Q3_K_M (about 15.99 GB).
Can I run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF fully on the GPU using Q5_K_S (about 23.38 GB).
What context length does bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF support?
bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF supports a native context length of up to 262,144 tokens. A longer context grows the KV cache, so it increases the memory needed to run the model.
What is the best quantization for bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF?
For bartowski/Kwaipilot_KAT-Coder-V2.5-Dev-GGUF, a strong default is Q4_K_M, which needs about 20.8 GB and keeps most of the quality while roughly halving the memory versus 8-bit. With VRAM to spare, Q5_K_M or Q6_K add a little more quality; if you are tight on memory, a smaller quantization still runs. Pick the highest quantization that fits your VRAM.
