DeepSeek has become the default cost-optimization play for SEA AI teams in 2026. OCBC Bank in Singapore already uses DeepSeek for internal market trend analysis. For Indonesian and Vietnamese SMEs that can't justify GPT-4 API bills, DeepSeek V3 cuts monthly AI costs from $500+ to under $50 for the same workload. The open-source models also allow Thai enterprises with strict data residency requirements to run models entirely on-premise.
