Build a simple Google OAuth login API in Python with FastAPI. Include login redirect, callback handler, JWT token generation, protected user profile endpoint, unit tests, Dockerfile, and API documentation.
Kimi K3: Automate Workflows and Visual Creation with Multimodal AI
Kimi K3 is a large-scale reasoning model designed for long-horizon projects, deep research, and multimodal understanding across text, images, and videos. Loopa's AI agent uses Kimi K3 to analyze information, understand your goals, process files, execute multi-step tasks, and deliver completed results.
I'll create a FastAPI app with Google OAuth flow, JWT handling, protected routes, tests, and Docker packaging.
Successfully created FastAPI project at /home/agents/.loopa/workspace/kimi-k-3/custom/google_oauth_api with main.py, test_main.py, Dockerfile, and requirements.txt. pytest: 6 passed.
Done! I built a complete FastAPI Google OAuth login API. It includes a /auth/login redirect, /auth/callback token exchange, JWT-protected /users/me endpoint, 6 passing pytest tests, a Dockerfile, and auto-generated OpenAPI docs at /docs.

Researchers and Analysts
Researchers and analysts working through large volumes of source material can use the agent to search, cross-reference, and summarize findings into a structured output instead of manually reading and organizing each source.
K3 is a sparse Mixture-of-Experts (MoE) model with a total parameter count of 2.8 trillion. It is the largest model released by Moonshot to date and is claimed by the company to be the largest open-weights model released so far. While early leaks in the days leading up to the launch suggested a figure of around 2.5 trillion, the confirmed figure is 2.8 trillion. Based on the shorthand "2.8T-A50B" circulating online, it is estimated that the number of activated parameters per token is approximately 50 billion; although Moonshot has not officially announced this specific figure, the estimate serves as a reasonably accurate reference rather than an exact value.
