Cover image for I’ve open-sourced AI API Proxy,
I’ve open-sourced AI API Proxy, a lightweight gateway that standardizes calls to multiple AI providers through an OpenAI-style API. Why it matters: easier vendor switching, centralized keys/quotas, and response caching to cut latency and cost. 🔗 GitHub: https://github.com/Resaqulyubi/ai-api-proxy (https://github.com/Resaqulyubi/ai-api-proxy)🧪 Live example app: https://portfolio.qulyubis.biz.id/?app=16 Highlights: - One endpoint, many providers/models - Built-in caching + retries - Simple auth & rate limits per client - Logs/metrics for observability I’m looking for feedback & contributors. If you’d like to collaborate, DM me, and please ⭐ the repo! While I’m waiting for the first client, I’m staying consistent: weekly small ships-bug fixes, docs polish, new integration examples, and mini benchmarks. Progress over perfect.🔥

Key Achievements ✅ Seamless Real-World Navigation: The robot now autonomously navigates dynamic spaces, avoiding obstacles and reaching destinations with precision—powered by ROS 2 Nav2 and our tuned path-planning algorithms. ✅ End-to-End AI Integration: Combining ChatGPT-4o, RAG, and Whisper, the robot answers contextual queries (e.g., “Where’s the lobby?”) and executes navigation tasks in one fluid workflow. Demo Highlights 1️⃣ Natural Language Interaction: Asked the robot for department info, and it responded instantly with accurate, AI-retrieved details. 2️⃣ Voice-Guided Navigation: Commanded, “Take me to Teleconference Room ”—the robot mapped the optimal path, dodged obstacles, and arrived autonomously. 3️⃣ Intuitive UI Feedback: The onboard interface displayed interactive prompts for users.
