It seems that there will be many products and forms of agent in

  • Why does it seem that only coding agent has emerged? One perspective is: Is AI Agent a technical term or a product form? Even at the end of 2025, the current situation is still technically called this, and the product naming is also called this. Even the word Agent itself has been around for a long time. If you look at the AI ​​Agent in 2025 from the technical side, it has actually made great progress:
  • The AI ​​Agent has improved the ability and accuracy of tool integration, and the basic model side has basically been specially trained with agentic capabilities to adapt to the AI ​​Agent.
  • Contextual engineering has gone from concept to engineering implementation to large-scale popularization in a short time, which has greatly accelerated the control ability, accuracy, and memory ability of the AI ​​Agent when interacting with large models.
  • Agent Infra has also made great progress, and now the Agent infrastructure can support hundreds of sub-agents. Activation and release in a short time 4 The Coding Agent capabilities mentioned in this post can be divided into model-side training that can be divided into front-end UI related code capability improvement (images, interfaces, PPT...), voice TTS, back-end code pre-training, and improvement of mathematical capabilities (in fact, mathematical capabilities are very important for coding) 5 AI Agent startups have made great innovations and progress at the application layer engineering level, so that the basic model in turn learns from the application side. A typical example is Claude learning manus @ManusA I launched Claude Skill, and now all major model manufacturers are launching their own Skills one after another. Therefore, it should be called the first year of AI Agent technology, which is more accurate. What I see through my eyes is huge technological progress.
