In 2025, the open-source large-language-model ecosystem saw significant growth with the release of Kimi K2 Thinking and DeepSeek-R1/V3, both utilizing Mixture-of-Experts (MoE) architectures and supporting extended context windows. Kimi K2 Thinking, developed by Moonshot AI, is optimized for agentic workflows, enabling complex, multi-step tasks through features like long-horizon reasoning and tool orchestration. In contrast, DeepSeek-R1, from the DeepSeek research lab, excels in logical reasoning and mathematics, supported by a reinforcement-learning pipeline. Both models are integrated into Clarifai's platform, which facilitates deployment and orchestration, allowing users to leverage the models' strengths in areas such as agentic reasoning, coding, and complex reasoning tasks. While Kimi K2 offers advanced tool use and autonomy at a higher cost, DeepSeek-R1 provides cost-effective solutions for reasoning-focused applications. With emerging innovations like Kimi Linear and DeepSeek-R2 on the horizon, the landscape is evolving towards more efficient models capable of handling even larger contexts and more sophisticated tasks.
