BowLingual-12B-v1

BowLingual-12B-v1 is a fine-tuned version of google/gemma-4-12B-it, intended primarily for natural English-to-Thai conversational translation.

It targets informal messages such as LINE and Messenger chats, where literal textbook translation often sounds stiff or unnatural.

Intended use

• —English-to-Thai conversational translation
• —Informal, natural-sounding Thai messages
• —Preserving tone, directness, and emotional intensity
• —Prompt-driven translation pipelines

Usage

Install the dependencies:

pip install -U transformers torch accelerate

Example:

from transformers import AutoModelForMultimodalLM, AutoProcessor

model_id = "stenml/BowLingual-12B-v1"

processor = AutoProcessor.frompretrained(modelid) model = AutoModelForMultimodalLM.frompretrained( modelid, dtype="auto", device_map="auto", )

messages = [ { "role": "user", "content": "Translate into natural casual Thai: I'm almost home.", } ]

inputs = processor.applychattemplate( messages, tokenize=True, returndict=True, returntensors="pt", addgenerationprompt=True, enable_thinking=False, ).to(model.device)

output = model.generate(**inputs, maxnewtokens=256) generated = output[0][inputs["inputids"].shape[-1]:] print(processor.decode(generated, skipspecial_tokens=True))

Default generation settings

• —Temperature: 1.0
• —Top-p: 0.95
• —Top-k: 64

Translation applications may benefit from lower-temperature or deterministic decoding, depending on the prompt and desired amount of stylistic variation.

Evaluation

No formal benchmark results are currently published for this release. Test it against representative conversational messages before production use.

Limitations

• —Primarily intended for English-to-Thai conversational translation
• —May produce inaccurate, unnatural, or overly literal translations
• —May hallucinate information absent from the source
• —Not validated for legal, medical, financial, or safety-critical translation
• —Multimodal behavior has not been formally evaluated after fine-tuning
• —Training-data and hyperparameter details are not currently published
