Nanthasit/sakthai-coder-browser
Nanthasit/sakthai-coder-browser is a 1.54 billion parameter Qwen2.5-Coder-1.5B-Instruct fine-tune, developed by Nanthasit, designed as a browser automation assistant. It outputs structured XML/JSON tool calls for web interaction, enabling navigation, clicking, typing, and content extraction. The model has a 32,768 token context length and is part of the SakThai Model Family, though its current weights are corrupted and not deployable.

Model Overview
Nanthasit/sakthai-coder-browser is a 1.54 billion parameter model, fine-tuned from Qwen2.5-Coder-1.5B-Instruct by Nanthasit, specifically for browser automation. It is designed to interact with web pages by generating structured <tool_call> XML/JSON outputs, enabling actions like navigation, clicking elements, typing text, and extracting content.
Key Capabilities (when repaired)
- Browser Automation: Generates tool calls for web interaction.
- Structured Output: Produces
<tool_call>XML/JSON for actions such as:browser_navigate(url)browser_click(element)browser_type(element, text)browser_extract()
- Qwen2.5 Tool-Calling Format: Utilizes a custom
chat_template.jinjafor tool-calling, supporting multi-turn interactions. - Context Length: Features a maximum context length of 32,768 tokens.
Current Status and Limitations
CRITICAL: This model is currently BROKEN and NOT DEPLOYABLE. The merged weights are corrupted due to a faulty LoRA merge, specifically affecting attention-projection bias tensors. Evaluation attempts resulted in zero output tokens and whitespace loops, indicating severe functional impairment. Users are advised not to deploy this version until the weights are re-merged and re-verified by the developer. It is text-only, primarily trained on English web interactions, and not servable on HF serverless inference in its current state. A GGUF variant and the unmerged LoRA adapter are also available, but the GGUF variant is also affected by the corrupted weights.
