Shining Valiant 3: [Qwen3-1.7B](https://huggingface.co/ValiantLabs/Qwen3-1.7B-ShiningValiant3), [Qwen3-4B](https://huggingface.co/ValiantLabs/Qwen3-4B-ShiningValiant3), [Qwen3-8B](https://huggingface.co/ValiantLabs/Qwen3-8B-ShiningValiant3), [gpt-oss-20b](https://huggingface.co/ValiantLabs/gpt-oss-20b-ShiningValiant3)


Shining Valiant 3 is a science, AI design, and general reasoning specialist built on gpt-oss-20b.
- Finetuned on our newest [science reasoning](https://huggingface.co/datasets/sequelbox/Celestia3-DeepSeek-R1-0528) data generated with [Deepseek R1 0528!](https://huggingface.co/deepseek-ai/DeepSeek-R1-0528)
- AI to build AI: our [high-difficulty AI reasoning](https://huggingface.co/datasets/sequelbox/Mitakihara-DeepSeek-R1-0528) data makes Shining Valiant 3 your friend for building with current AI tech and discovering new innovations and improvements!
- Improved [general and creative reasoning](https://huggingface.co/datasets/sequelbox/Raiden-DeepSeek-R1) to supplement problem-solving and general chat performance.
- Small model sizes allow running on local desktop and mobile, plus super-fast server inference!


## Prompting Guide
Shining Valiant 3 uses the [gpt-oss-20b](https://huggingface.co/openai/gpt-oss-20b) prompt format.

Shining Valiant 3 is a reasoning finetune; **reasoning level high is generally recommended.**

**NOTE: This release of Shining Valiant 3 currently uses bf16 for all parameters. Consider quantized models if you're not looking to use bf16.**

Example inference script provided by [gpt-oss-20b](https://huggingface.co/openai/gpt-oss-20b) to get started:

```python
from transformers import pipeline
import torch

model_id = "ValiantLabs/gpt-oss-20b-ShiningValiant3"

pipe = pipeline(
    "text-generation",
    model=model_id,
    torch_dtype="auto",
    device_map="auto",
)

messages = [
    {"role": "user", "content": "Reversible Cellular Automata (RCAs) are CAs that have an inverse rule, allowing the simulation to run backward in time. Explain the theoretical significance of RCAs in the context of modeling physical laws that are time-symmetric. Describe the additional constraints that must be placed on a rule set to ensure it is reversible and discuss the challenges in constructing non-trivial reversible rules."},
]

outputs = pipe(
    messages,
    max_new_tokens=12000,
)
print(outputs[0]["generated_text"][-1])
```
