[Model Submission] OpenAI-Compatible API — Xiaothink-T17-RWKV5-MLA-0.6B-Frontend

Nobody has claimed this yet.

**Organization:** Xiaothink Framework
**Submitter:** Individual developer / open-source contributor
**Model type:** Open weights + public API (OpenAI-compatible)

We would like to submit **Xiaothink-T17-RWKV5-MLA-0.6B-Frontend** to the Arena for evaluation. It is a 0.6B-parameter model trained from scratch, specialized in generating beautiful static frontend pages (single-file HTML/CSS/JS) from ultra-short prompts (10–20 tokens).

---

### Why This Model Fits Arena

- **Vertical Specialization:** Trained specifically for frontend static-page generation — a narrow but high-traffic category on Code Arena WebDev.
- **Primary Language Support (Chinese):** The model is specifically optimized for Chinese prompts and generating frontend pages with Chinese content, filling a gap for Chinese-language frontend tasks in the Arena.
- **Ultra-short Prompt Competence:** Produces complete, production-quality single-file HTML from ≤20-token descriptions, aligning with real user prompt patterns (Landing Page, Portfolio, Dashboard, etc.).
- **Competitive Blind-test Performance:** In an independent blind evaluation judged by DeepSeek-V4, the model **outperforms Llama-3-8B** and **approaches GPT-OSS-20B** quality on static frontend page generation tasks.
- **Open Weights:** Full model weights publicly available on ModelScope for transparency and reproducibility.
- **Novel Architecture:** RWKV-5 with Multi-head Latent Attention (MLA) — an RNN-Transformer hybrid offering constant memory usage and stable inference cost, relevant to Arena's diverse model pool.

### Obtaining an Evaluation API Key

The API is not open-access (rate-limited to protect inference compute). The Arena team can obtain a dedicated evaluation key with elevated quota by contacting:

- **Email:** `xiaothink@foxmail.com`
- **Subject:** `[Arena Evaluation Key Request] Xiaothink-T17 Frontend`
- We will provision a long-lived key with sufficient rate limits for Arena's voting volume and commit to keeping it active for the full 30-day evaluation window per Arena's Leaderboard Policy.

### Open Weights & Technical Details

- **ModelScope:** https://www.modelscope.cn/models/ericsjq/Xiaothink-T17-RWKV5-MLA-0.6B-Frontend
- **Official site:** http://xiaothink.top/
- **Architecture:** RWKV-5 with Multi-head Latent Attention (MLA)
- **Parameters:** 0.6B
- **Primary Language:** Chinese (optimized for Chinese prompts and content generation)
- **License:** see ModelScope model card
- **Training:** from-scratch (not a fine-tune of an existing base model)
- **Specialty:** static frontend page generation (single-file HTML/CSS/JS) from ultra-short prompts

### Blind-Test Evidence (DeepSeek-V4 as Judge)

An independent pairwise blind evaluation was conducted using DeepSeek-V4 as the LLM judge, comparing generated static frontend pages on a held-out prompt set. Results:

| Model | Relative Quality |
|---|---|
| Llama-3-8B (general) | Baseline — Xiaothink-T17 outperforms |
| GPT-OSS-20B (general) | Xiaothink-T17 approaches parity |
| **Xiaothink-T17-0.6B-Frontend** | **Exceeds Llama3-8B, ~matches GPT-OSS-20B in this narrow vertical** |

Full evaluation logs and prompt sets are available on request. We understand Arena will re-evaluate using its own native mechanism (human blind voting); the DeepSeek-V4 score is provided only as a capability reference.

### Availability Commitment

- API endpoint will remain publicly accessible for at least 30 days post-launch per Arena Leaderboard Policy.
- We will not pause or revoke access once testing begins.
- Compute is self-hosted on dedicated GPU infrastructure — not a shared free tier.
- We are prepared for the ~200-vote stabilization period and will maintain capacity throughout.

### Preferred Arena Category

- **Primary:** Code Arena → WebDev → HTML / Website
- **Secondary:** Code Arena → WebDev → UI Component

We are happy to make any API adjustments (additional endpoints, response format tweaks, etc.) the Arena team requires. Looking forward to your feedback.

Start by reviewing the Arena model-submission requirements and the proposed OpenAI-compatible GET /models and POST /chat/completions endpoints. Verify the ModelScope model details, API availability, evaluation category, and 30-day availability commitment; done means the submission is accepted for evaluation or has a documented reason for rejection.
