llama server ops
Example session with this skill installed
I need to swap the current model for a Qwen3.6-14B-A3B Q4_K_M GGUF on my dual 3060 setup. Maximize context for a single user. Walk me through the ladder protocol and service update.
- Read your context and instructions
- Compiled the llama server ops
I will now execute the ladder protocol to find the VRAM ceiling for the Qwen3.6-14B-A3B model and update your systemd service.
Llama-Server Deployment Plan
| Step | Action | Command/Metric |
|---|---|---|
| 1 | Stop existing services | systemctl stop llama-server |
| 2 | Ladder Test: 64K Context | 9.1GB VRAM (Measured) |
| 3 | Ladder Test: 128K Context | 10.0GB VRAM (Measured) |
| 4 | Target: 192K Context | 10.9GB VRAM (Best Fit for 12GB Card) |
| 5 | Update Unit File | sed -i 's/old-model.gguf/qwen3.6-14b-a3b-q4_k_m.gguf/' |
| 6 | Reload & Restart | systemctl daemon-reload && systemctl restart llama-server |
| 7 | Liveness Verification | GET /health -> {"status":"ok"} |

About this skill
The problem
Running local LLMs via llama-server often leads to silent failures, Out-Of-Memory (OOM) errors during long-context prefill, and deceptive health checks. Developers struggle to accurately predict VRAM usage for GGUF models across multi-GPU setups, especially when balancing context window size against batch parallelism.
What it does
- Manages the
llama-serverlifecycle, including safe model swaps, systemd unit updates, and daemon-reloads. - Calculates real-world VRAM ceilings for GGUF models, accounting for KV cache quantization and activation memory.
- Executes multi-stage verification protocols including context-soak tests and "needle in a haystack" retrieval benchmarks.
- Configures optimized sampling defaults and request parameters to suppress reasoning tokens in thinking models.
- Orchestrates multi-GPU offloading for Mixture-of-Experts (MoE) models and handles PCIe bandwidth optimization.
Frameworks & tools
llama.cpp (llama-server), Linux/WSL, systemd, NVIDIA CUDA (nvidia-smi), GGUF model format, and OpenAI-compatible API endpoints.
Why this beats prompting it yourself
Generic LLMs often use naive VRAM math that ignores sliding-window compression and compute buffer overhead. This skill uses a proven "ladder protocol" to measure actual hardware limits, preventing silent background launch failures and OOM crashes that occur 200 seconds into a prefill.
Use cases
- Deploying a persistent 192K context inference endpoint on consumer GPUs.
- Upgrading production GGUF weights without dropping the active service unit.
- Benchmarking MoE model performance and VRAM spill across multi-GPU sharding.
- Automating liveness probes that distinguish between "Loading model" and "Ready".
Known limitations
Platform limited to Linux and WSL. Focuses exclusively on the llama-server runtime; does not support Ollama-specific API endpoints or Intel Arc SYCL backends for non-LLM workloads.
