Claude Code + Codex CLI: Building a UNHINGED AI Video App
All About AI ā¢ August 24, 2025
All About AI demonstrates using Claude Code together with the Codex CLI and GPT5 to auto-generate a PRD, scaffold a React/NodeJS web app, and integrate AI services like Replicateās Ideogram, 11labs Music and TTS, then merge multi-scene videos and audio via FFMPEG.
Key Takeaways:
- GPT5 is used via Codex CLI to convert a draft app concept into a detailed PRD and feed it into Claude Codeās Opus mode for automated project planning and code generation.
- The app captures or uploads a reference image for scene 1, then uses rolling references in Replicateās Ideogram model across subsequent scenes, writes voiceover scripts and music prompts with GPT5 nano, and generates video segments with CLIP 2.1.
- GPT5 reviewed and corrected FFMPEG commands in the repo, and Claude Code applied those fixes to merge scene videos and overlay 11labs background music at 20% volume and voiceover at 100% volume.
Inside the expert network training every frontier AI model | Garrett Lord
Lennys Podcast ā¢ August 24, 2025
Garrett Lord explains how Handshake transformed its decade-old college career network of over 20 million students and alumni into a zeroāCAC expert data-labeling service for frontier AI labsāhitting $50 million ARR in four months and set to exceed $100 million ARR within its first year.
Key Takeaways:
- Handshakeās AI labeling arm reached $50 million ARR just four months after launching in January 2025, is on pace to surpass $100 million ARR within 12 months, and will eclipse its $200 million core business run rate in under two years.
- Frontier AI labs now drive most model improvements through post-training expert dataāsuch as reinforcement learning with human feedback, prompt-response pairs, step-by-step reasoning trajectories, and rubric evaluationsāinstead of relying solely on internet-scale pre-training.
- By leveraging its built-in audience of 20 million+ users (including 500 000 PhDs and 3 million masterās students) with zero customer acquisition cost, Handshake efficiently sources high-quality domain experts for seven leading AI labs, ensuring fast volume and retention.
