## Model Description

**SakThai Plus 1.5B Coder** is the coder-focused member of the SakThai Plus family. It is based on `Qwen/Qwen2.5-Coder-1.5B-Instruct` and targets two workflows: **code generation** and **tool-calling from code-oriented prompts**. This repository currently holds the recipe, metadata, and eval artifacts; weights are not uploaded yet.

This card exists so the training pipeline, evaluation history, and downstream integration points have a stable, versioned entry in the HF Hub. Once weights are pushed, it will become directly loadable with `transformers` and serveable with `llama.cpp` / Ollama from the repo.

**Why this repo matters in the family:**
- 🧑‍💻 **Code-first base:** `Qwen2.5-Coder-1.5B-Instruct` is a strong small-code model; this slot preserves the SakThai tool-calling adaptations for code use cases.
- 🔧 **Tool-calling discipline:** trained with code/agent instruction mix from `sakthai-combined-v7`.
- 📦 **GGUF-ready path:** once weights exist, the intended artifact is `q4_k_m` for CPU inference.
- 🧪 **Live eval history:** `.eval_results/` contains cron metadata snapshots and smoke probes from 2026-07-30 to 2026-08-01.

## Status

| Item | State |
|------|-------|
| Weights | ❌ Not uploaded yet |
| GGUF | ❌ Not uploaded yet |
| Config / metadata | ✅ Present |
| Eval history | ✅ `.eval_results/` snapshots present |
| Hub inference | ❌ Router returns `model_not_supported` until weights are pushed |

If you need a working SakThai coder model today, use:
- [Nanthasit/sakthai-coder-1.5b](https://huggingface.co/Nanthasit/sakthai-coder-1.5b)
- [Nanthasit/sakthai-context-1.5b-merged-v2](https://huggingface.co/Nanthasit/sakthai-context-1.5b-merged-v2)

## How to Use

This repository is a **workflow placeholder** until weights are uploaded. Below are the two intended paths once weights are present.

### Option A — Load with transformers (future)

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "Nanthasit/sakthai-plus-1.5b-coder"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

messages = [
    {"role": "system", "content": "You are SakThai-Coder, a helpful coding assistant."},
    {"role": "user", "content": "Write a Python function that checks if a string is a palindrome."},
]
prompt = tokenizer.apply_chat_template(messages, tokenize=False)
inputs = tokenizer(prompt, return_tensors="pt")
out = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(out[0], skip_special_tokens=True))
```

### Option B — CPU / offline inference via GGUF (future)

```bash
# After weights/GGUF are pushed:
huggingface-cli download Nanthasit/sakthai-plus-1.5b-coder --include "*.gguf" --local-dir ./
llama-cli -m sakthai-plus-1.5b-coder-q4_k_m.gguf \
  --prompt "[INST] Write a Python function that checks if a string is a palindrome. [/INST]" \
  -n 256
```

## Training Details

| Detail | Value |
|--------|-------|
| **Base model** | `Qwen/Qwen2.5-Coder-1.5B-Instruct` |
| **Dataset** | [Nanthasit/sakthai-combined-v7](https://huggingface.co/datasets/Nanthasit/sakthai-combined-v7) |
| **Framework** | Transformers + PEFT/LoRA-family recipe |
| **License** | Apache 2.0 |

## Evaluation & Benchmarks

This repo does **not yet** have verified model-level scores because there are no weights to load. The closest available references:

| Benchmark | Source | Status |
|-----------|--------|--------|
| MBPP pass@1 | Base model `Qwen2.5-Coder-1.5B-Instruct` | Inherited; not measured on this fine-tune |
| HF router inference | `.eval_results/benchmark-20260731_192407.yaml` | `model_not_supported` until weights are uploaded |
| Code smoke | `.eval_results/inference-check-2026-07-31.yaml` | Not runnable in this environment; metadata snapshot only |

When weights are pushed, rerun:
```bash
llama-bench sakthai-plus-1.5b-coder-q4_k_m.gguf
```
and add results to `.eval_results/`.

## Limitations

- **No weights uploaded yet.** This repo is currently a metadata / workflow placeholder.
- **No standalone benchmarks yet.** Published numbers are inherited from the base model, not this SakThai fine-tune.
- **No hosted inference.** HF inference providers cannot serve a repo without weights.
- **Code quality depends on prompt format.** This slot is tuned for tool + code prompts; plain chat performance may differ from the base instruct checkpoint.
- **Small-model tradeoffs.** At 1.5B parameters, complex multi-file reasoning and very long context may degrade.
