Moonshot AI has silently updated its flagship Kimi AI assistant to version K2.5, introducing significant improvements in multimodal processing and vision understanding.
Spotted in user interactions as early as January 26, 2026, this low-key release enhances Kimi’s ability to analyze images, explain complex diagrams, and handle visual content alongside text-based reasoning.
Building on the strong foundation of Kimi K2 and K2 Thinking, K2.5 positions the assistant as a more versatile tool for technical explanations, creative tasks, and everyday queries.
Core Upgrades in Kimi K2.5
Kimi K2.5 builds on Moonshot AI’s Mixture-of-Experts (MoE) architecture, maintaining the 1 trillion total parameters with 32 billion activated per token. The key enhancements focus on vision and multimodal integration:
- Image Understanding and Analysis: Kimi can now process uploaded images, diagrams, and memes, providing detailed explanations of technical architectures, safety concepts, or creative visuals.
- Multimodal Reasoning: Combines visual input with text prompts for deeper insights, such as breaking down attention mechanisms in research diagrams or interpreting symbolic content.
- Improved Tool Use: Supports advanced agentic workflows, including code execution during thinking steps and multi-step problem solving.
- Long Context Handling: Up to 256K tokens for extended conversations and complex queries.
- Deep Thinking Mode: Step-by-step reasoning for math, logic, coding, and research tasks.
These updates make Kimi particularly strong for users working with visual data, such as developers decoding model architectures, students analyzing charts, or creators exploring memes and illustrations.
Key Features Comparison: Kimi Evolution
| Version | Release Period | Key Strengths | Multimodal Support | Parameter Scale |
|---|---|---|---|---|
| Kimi K2 | July 2025 | Agentic intelligence, coding excellence | Limited | 1T total / 32B active |
