Astra V1 Pro

Astra V1 Pro is LW AI's multi-model fusion LLM that uses intelligent routing and ensemble inference to dynamically select and combine the best models for each query. It delivers superior cost-performance by automatically optimizing across model selection, latency, and accuracy.

How It Works

Astra V1 Pro automatically routes each request through the optimal model(s) based on:

• Task complexity — Simple queries use faster, cheaper models; complex reasoning uses more powerful models
• Cost optimization — Dynamically selects the most cost-effective model for the required quality level
• Ensemble inference — Combines outputs from multiple models for critical tasks requiring high accuracy

Example

from openai import OpenAI

client = OpenAI(
    base_url="https://openapi.linkwo.ai/v1",
    api_key="YOUR_API_KEY"
)

response = client.chat.completions.create(
    model="astra",
    messages=[
        {"role": "user", "content": "Analyze this financial report and provide key metrics: ..."}
    ],
    temperature=0.3
)

print(response.choices[0].message.content)

Best Practices

• Use for general-purpose tasks where automatic model selection adds value
• Combine with specific models (DeepSeek V4 Pro, GLM-5.1) when you need deterministic model behavior
• Leverage for cost-sensitive applications that still require high quality
