AI Chat Workspace — Multi-Model Streaming Chat Platform

Problem

Teams evaluating or relying on AI assistants rarely want to be locked to a single model provider — different models are better at different tasks, and a chat platform tied to one vendor forces a compromise every time the "best" model for a job isn't the one that's wired in.

Action

• Built a chat platform supporting multiple underlying models — Gemini 2.5 and GPT-4o — behind a single consistent interface, so switching models doesn't mean switching tools.
• Implemented real-time streaming via Server-Sent Events (SSE), so responses appear token-by-token rather than as a blocking wait-then-dump.
• Supported multimodal file input, letting users attach images and documents directly into the conversation rather than working around a text-only interface.

Result

A single chat workspace that gives users model choice instead of vendor lock-in, with the streaming responsiveness and file-input flexibility users expect from a modern AI interface.
