Market Shock Event
DeepSeek V3 release triggers tech stock selloff. Training cost of $5.6M challenges frontier AI cost assumptions.
ImpactOpen-weight models, rock-bottom API pricing, and the lab that proved frontier AI does not require billion-dollar training budgets. These articles break down the models, the costs, and the trade-offs.
DeepSeek publishes model weights for self-hosting. The V3 model runs 671 billion parameters in a Mixture of Experts architecture. R1 adds explicit reasoning with chain-of-thought. Both available for commercial use under permissive licenses.
DeepSeek's API undercuts competitors on price - starting at $0.14/million input tokens for the V3 model. The platform serves completions, chat, and reasoning endpoints. Rate limits are generous for the price point.
DeepSeek's January 2025 release caused a market shock. Training costs reported at $5.6 million challenged the assumption that frontier AI requires billion-dollar budgets. The open-weight approach pressures closed-model providers on pricing.
