+
+# LlamaFactory Fine-Tuning
+
+LlamaFactory fine-tunes open-weight LLMs (LoRA/QLoRA and full-parameter; SFT, DPO and more) through the `llamafactory-cli` command driven by YAML configs.
+
+## Before you start
+
+If the user's message only invokes this skill (e.g. "use llamafactory skill") without a concrete request, ask the user what they want to fine-tune. Do not run any command until the goal is clear.
+
+Confirm before training:
+
+- GPU memory (`nvidia-smi`) — it bounds the model size and method; LoRA needs far less than full fine-tuning.
+- The base model: a Hugging Face id or a local path.
+- The dataset: where it lives and which format it is in.
+- The goal: SFT with LoRA is the usual starting point.
+
+## Install
+
+```bash
+git clone --depth 1 https://github.com/hiyouga/LlamaFactory.git
+cd LlamaFactory
+pip install -e .
+pip install -r requirements/metrics.txt   # optional: evaluation metrics
+```
+
+## Data
+
+Register every dataset in `data/dataset_info.json`; the alpaca and sharegpt formats are supported. A minimal local entry:
+
+```json
+"my_dataset": { "file_name": "my_dataset.json" }
+```
+
+alpaca rows carry `instruction` / `input` / `output`; sharegpt rows carry a `conversations` list. Put the data file under `data/` next to the registry.
+
+## Train
+
+Training is driven by a YAML config. Start from the shipped example `examples/train_lora/qwen3_lora_sft.yaml`, or save a minimal config as `my_sft.yaml`, e.g. for [Qwen/Qwen3-1.7B](https://huggingface.co/Qwen/Qwen3-1.7B):
+
+```yaml
+model_name_or_path: Qwen/Qwen3-1.7B
+trust_remote_code: true
+stage: sft
+do_train: true
+finetuning_type: lora
+lora_rank: 8
+lora_target: all
+dataset: my_dataset
+template: qwen3
+output_dir: saves/qwen3-1.7b/lora/sft
+learning_rate: 1.0e-4
+num_train_epochs: 3.0
+bf16: true
+```
+
+```bash
+llamafactory-cli train my_sft.yaml
+```
+
+`llamafactory-cli webui` launches the no-code web UI for the same workflow.
+
+## Merge and export
+
+Merge the LoRA adapter into the base weights for standalone serving. Start from `examples/merge_lora/qwen3_lora_sft.yaml`, pointing `model_name_or_path`, `adapter_name_or_path` and `template` at your run (never merge into a quantized base):
+
+```yaml
+model_name_or_path: Qwen/Qwen3-1.7B
+adapter_name_or_path: saves/qwen3-1.7b/lora/sft
+template: qwen3
+trust_remote_code: true
+export_dir: saves/qwen3-1.7b-sft-merged
+```
+
+```bash
+llamafactory-cli export my_merge.yaml
+```
+
+## Try the result
+
+Both commands take an inference config — derive it from `examples/inference/qwen3_lora_sft.yaml`, again pointing the model, adapter and template at your run:
+
+```yaml
+model_name_or_path: Qwen/Qwen3-1.7B
+adapter_name_or_path: saves/qwen3-1.7b/lora/sft
+template: qwen3
+infer_backend: huggingface
+trust_remote_code: true
+```
+
+```bash
+llamafactory-cli chat my_infer.yaml   # interactive chat with the tuned model
+llamafactory-cli api my_infer.yaml    # OpenAI-compatible API server
+```
+
+## Close the loop
+
+Serve the merged export as a standalone endpoint — vLLM serves the export directory directly, while Ollama needs an import first (a `Modelfile` with `FROM /path/to/export`, then `ollama create`; supported model architectures only) — then register the endpoint with PenguinHarness so agents can build, evaluate and tune AI apps on the fine-tuned model end to end.

+# Ollama Serving
+
+Ollama runs open-weight models locally with automatic GPU detection and an OpenAI-compatible API on `http://localhost:11434`.
+
+## Before you start
+
+If the user's message only invokes this skill (e.g. "use ollama skill") without a concrete request, ask the user what they want. Do not run any command until the goal is clear.
+
+Ask the user which model to run; if they have no preference, recommend the small default [Qwen/Qwen3.5-0.8B](https://huggingface.co/Qwen/Qwen3.5-0.8B) (`ollama pull qwen3.5:0.8b`). The model must fit the machine's RAM/VRAM.
+
+Ollama runs everywhere — macOS, Linux and Windows, on CPUs as well as NVIDIA/AMD GPUs — so engine choice follows the user's preference: Ollama is the simple default, while vLLM targets high-throughput GPU serving. Check the current state first:
+
+```bash
+ollama --version   # is Ollama installed?
+ollama ps          # is the service already serving models?
+```
+
+If port 11434 is already serving, reuse that instance — never kill an existing Ollama process.
+
+## Suggested workflow
+
+1. Ask the user which model to run; with no preference, recommend [Qwen/Qwen3.5-0.8B](https://huggingface.co/Qwen/Qwen3.5-0.8B) (`qwen3.5:0.8b`).
+2. Pick the engine the user prefers: Ollama is the default; vLLM covers high-throughput GPU serving.
+3. Install Ollama if missing, then `ollama pull qwen3.5:0.8b`.
+4. Verify with `curl http://localhost:11434/v1/models`.
+5. Register the endpoint: `penguin config model add ... --client-type openai --base-url http://localhost:11434/v1` — a pulled Ollama model is not visible to Penguin until added.
+6. Confirm the new entry with `penguin config model list`.
+
+## Install
+
+```bash
+curl -fsSL https://ollama.com/install.sh | sh   # Linux; macOS/Windows use the desktop app
+```
+
+The service then listens on `http://localhost:11434`.
+
+## Pull and run
+
+```bash
+ollama pull qwen3.5:0.8b   # download a model
+ollama run qwen3.5:0.8b    # interactive chat (pulls first if missing)
+ollama list                # downloaded models
+ollama ps                  # models loaded in memory
+ollama stop qwen3.5:0.8b   # unload a model
+```
+
+## OpenAI-compatible endpoint
+
+The endpoint is `http://localhost:11434/v1`; any non-empty API key is accepted (conventionally `ollama`):
+
+```bash
+curl http://localhost:11434/v1/models
+```
+
+## Context length
+
+The default context window is small, and agent sessions need a large one. Raise it in the server's environment:
+
+```bash
+OLLAMA_CONTEXT_LENGTH=32768 ollama serve   # systemd service: set it via `systemctl edit ollama`
+```
+
+Or bake it into a model variant with a Modelfile:
+
+```
+FROM qwen3.5:0.8b
+PARAMETER num_ctx 32768
+```
+
+```bash
+ollama create qwen3.5-32k -f Modelfile
+```
+
+## Register with PenguinHarness
+
+Model configuration is the penguin CLI's job — `penguin config model add` registers an endpoint and `penguin config model list` shows what has been registered. A pulled Ollama model is not visible to Penguin until you add it:
+
+```bash
+penguin config model add --provider custom --client-type openai \
+  --base-url http://localhost:11434/v1 --model-id qwen3.5:0.8b --api-key ollama
+penguin config model list   # the new entry should now be listed
+```

+# vLLM Serving
+
+vLLM serves open-weight LLMs on local GPUs with high-throughput inference behind an OpenAI-compatible API, ready for chat and agent workloads.
+
+## Before you start
+
+If the user's message only invokes this skill (e.g. "use vllm skill") without a concrete request, ask the user what they want. Do not run any command until the goal is clear.
+
+Ask the user which model to serve; if they have no preference, recommend the small default [Qwen/Qwen3.5-0.8B](https://huggingface.co/Qwen/Qwen3.5-0.8B). Also ask what context length the workload needs.
+
+vLLM needs an NVIDIA or AMD GPU. Engine choice follows the user's preference: Ollama also runs on GPUs and is the simpler default — pick vLLM for high-throughput serving, and Ollama on macOS or CPU-only machines, which vLLM does not serve. Confirm the hardware first:
+
+```bash
+nvidia-smi          # NVIDIA: GPU model and free VRAM (AMD ROCm: rocm-smi)
+python3 --version   # a recent Python is required
+```
+
+The model must fit the available VRAM — model size and context length drive the serve flags below.
+
+## Suggested workflow
+
+1. Ask the user which model to serve; with no preference, recommend [Qwen/Qwen3.5-0.8B](https://huggingface.co/Qwen/Qwen3.5-0.8B).
+2. Pick the engine the user prefers: vLLM for high-throughput GPU serving; Ollama is the simple default and the choice on macOS or CPU-only machines.
+3. Serve on a free port, with the tool-calling flags whenever agents will call it (see below).
+4. Verify with `curl http://localhost:8000/v1/models`.
+5. Register the endpoint: `penguin config model add ... --client-type openai --base-url http://localhost:8000/v1` — a served model is not visible to Penguin until added.
+6. Confirm the new entry with `penguin config model list`.
+
+## Install
+
+Use a fresh virtual environment (or `uv`):
+
+```bash
+python3 -m venv .venv && source .venv/bin/activate
+pip install vllm
+```
+
+## Serve
+
+```bash
+vllm serve Qwen/Qwen3.5-0.8B --port 8000
+```
+
+This exposes an OpenAI-compatible API at `http://localhost:8000/v1`. Key flags:
+
+- `--served-model-name <name>` — the model id clients request (defaults to the model path).
+- `--api-key <key>` — require this bearer token on every request.
+- `--max-model-len <n>` — context window; agent sessions need a large one.
+- `--gpu-memory-utilization <0..1>` — fraction of VRAM to claim (default 0.9).
+- `--tensor-parallel-size <n>` — shard across `n` GPUs.
+- `--dtype <auto|bfloat16|float16>` and `--quantization <awq|gptq|fp8>` — precision and quantized weights.
+
+If the port is taken, pick a free one — never kill a process already listening on it.
+
+## Tool calling — required for agents
+
+Agent harnesses (PenguinHarness included) send `tools` with their requests. vLLM must opt in at startup:
+
+```bash
+vllm serve Qwen/Qwen3.5-0.8B --enable-auto-tool-choice --tool-call-parser hermes
+```
+
+Choose the parser for the model family — e.g. `hermes` for Qwen models, `llama3_json` for Llama models. Without these flags, requests that set tool_choice fail with `400 "auto" tool choice requires --enable-auto-tool-choice and --tool-call-parser to be set`.
+
+## Verify
+
+```bash
+curl http://localhost:8000/v1/models
+```
+
+## Register with PenguinHarness
+
+Model configuration is the penguin CLI's job — `penguin config model add` registers an endpoint and `penguin config model list` shows what has been registered. A served model is not visible to Penguin until you add it:
+
+```bash
+penguin config model add --provider custom --client-type openai \
+  --base-url http://localhost:8000/v1 --model-id <served-model-name> --api-key <key>
+penguin config model list   # the new entry should now be listed
+```
+
+## Troubleshooting
+
+- Out of memory at startup: lower `--gpu-memory-utilization` or `--max-model-len`, or serve a quantized model.
+- Long prompts truncated or context-length errors: raise `--max-model-len` (bounded by VRAM).
+- `400` on tool calls: restart the server with the tool-calling flags above.
