⚙️ Training Procedure

🚀 Training Pipeline:

The model starts from Mistral Large 3 Base and undergoes the following fine-tuning:

1. 🎯 Domain-Specific Fine-Tuning: Parameter adaptation using the electrohydrodynamics dataset
2. 🔄 Iterative Refinement: Repeated training rounds with manual review of sampled outputs
3. 🧠 Long-Context Training: Training examples include extended documents to exercise the context window

💡 How to Use

Mistral Large 3 requires a full node (B200 or H200 in FP8; H100 or A100 in NVFP4). The recommended path is serving with vLLM and querying through the OpenAI-compatible endpoint.

🔧 Serve:

vllm serve Taylor658/Electrohydrodynamics \
  --tokenizer_mode mistral \
  --max-model-len 262144 \
  --tensor-parallel-size 8

🔧 Query:

from openai import OpenAI

client = OpenAI(api_key="EMPTY", base_url="http://localhost:8000/v1")
model = client.models.list().data[0].id

resp = client.chat.completions.create(
    model=model,
    temperature=0.15,
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Explain how the Hall parameter governs electron mobility in a Hall Effect Thruster discharge channel. State assumptions."}
    ],
)
print(resp.choices[0].message.content)

📝 Example Queries:

• ⚡ "How does the Hall parameter affect electron mobility in a Hall Effect Thruster operating at 300V discharge voltage?"
• 🔬 "What are the primary factors influencing ionization efficiency in the thruster channel, and how do they interact?"
• 📊 "Summarize this simulation report and identify the parameters most sensitive to efficiency."
• 💻 "Draft a CFD simulation script for modeling plasma flow in a cylindrical HET channel."

⚠️ Limitations

• 🔢 First Release: v1.0 is a first release; behavior will change in later versions
• 🎯 Domain Specificity: Optimized for Hall Effect Thruster fluid dynamics; may degrade outside this domain
• 🔬 Synthetic Data Foundation: Trained exclusively on synthetic data; outputs must be validated against experimental results
• 📏 No Published Benchmarks: Quantitative evaluation is pending
• 💾 Computational Resources: 675B total parameters; requires a multi-GPU node for inference
• 📊 Long Context: Quality may degrade toward the upper end of the 256k window
