Hi, this is a serious AI product, and the way you’ve broken it into chat, research, coding, media, and documents makes a lot of sense. We are comfortable stitching together open-source models and low-cost APIs into one clean system instead of forcing everything through a single LLM. FastAPI, LangChain-style orchestration, background workers, and media pipelines (image/video/docs) are all things I’m used to structuring carefully. The focus would be on making each mode feel reliable and usable, not just impressive on paper. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Lets connect over chat so we could discuss the details.
