Anthropic’s Claude 4 represents a significant leap in AI capability, introducing what the company calls “extended thinking” — a mode where the model can reason through complex problems step by step before responding.
What Makes Claude 4 Different
Unlike previous language models that generate responses token by token, Claude 4’s extended thinking allows it to break down complex problems, consider multiple approaches, and self-correct before presenting a final answer. In benchmark tests, this approach improved accuracy on mathematical reasoning by 47% and coding tasks by 38%.
Real-World Applications
The implications for developers and enterprises are substantial. Claude 4 can now handle multi-step software architecture decisions, financial analysis with competing variables, and scientific research synthesis — tasks that previously required significant human oversight.
The Southeast Asian Angle
For the Malaysian and Singaporean tech ecosystem, Claude 4’s improved multilingual capabilities are particularly noteworthy. The model now handles Bahasa Malaysia, Mandarin, and Tamil with near-native fluency, opening doors for localised AI applications across the region.
Anthropic is offering Claude 4 through its API starting today, with pricing at $15 per million input tokens and $75 per million output tokens for the flagship model.
