Best For
Complex agentic workflows requiring tool orchestration, web browsing, and computer useMultimodal analysis combining text, images, audio, and video in a single turnEnterprise-grade production systems needing the highest quality across all dimensionsLong-document reasoning over 500K+ token contexts with high recall
Complex software engineering — the best model for codebase-level refactoring, bug fixing, and feature implementationEnterprise applications requiring the highest safety and alignment standardsAgentic computer use workflows for GUI automation and testingLong codebase analysis with 1M beta context window
Weaknesses
- Expensive at scale — 6x the cost of GPT-5.4-mini for marginal quality gains on simpler tasks
- Latency is noticeable on complex reasoning chains (5-15s for hard problems)
- Computer use agent is powerful but occasionally takes suboptimal action paths
- Audio processing adds ~2s latency and is billed at a higher effective token rate
- The most expensive frontier model at $5/$25 per million tokens
- Slower inference than GPT-5.4 due to Anthropic's safety-first architecture
- No audio or video understanding
- 1M context is still in beta and may have edge-case quality issues at extreme lengths
