Claude Opus 4 - Starrise AI

Claude Opus 4 is Anthropic’s latest flagship model, available through Starrise AI via OpenAI-compatible interface. It represents a significant capability leap, excelling at complex reasoning, advanced coding, agentic tasks, and deep analysis.

Key Capabilities

OpenAI-compatible — Drop-in replacement for the OpenAI SDK, no other code changes needed
Exceptional reasoning — State-of-the-art performance on complex multi-step problems
Advanced coding — Best-in-class code generation, debugging, and architecture design
Agentic capabilities — Designed for autonomous multi-step task execution
Long context — Supports large document processing and multi-turn conversations
Streaming — Real-time token streaming via SSE

Quick Example

  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-4-20250514",
    "messages": [
      { "role": "user", "content": "Explain quantum entanglement in simple terms." }
    ]
  }'

from openai import OpenAI
