Anthropic: Claude Sonnet 4.5

This advanced hybrid-reasoning AI is optimized for coding, deep logic, and long-running agent workflows. It excels across the software lifecycle—generating code, debugging, refactoring multi-file projects, and maintaining large codebases—while tracking tools, context, and quality assurance in the same session. Designed for enterprise needs, it supports background automation, parallel tool calls, and extended tasks (including very long production cycles) with strong context retention. Use clear prompts that define languages, targets, and tools to maximize accuracy. Always human-review outputs for security, style, and logic. Plan infrastructure, monitoring, and cost controls for long contexts and high-throughput automation.
