Audit Local AI Coding Logs to Track Your Real Work
Claire Vo analyzed her local Claude Code and Codex logs to reveal coding dropped below 40%. Here is how to run the meta-analysis.
I’m using Jev more than Opus 5.5 or GPT-6. Here’s why.
With Claire Vo · Tuesday, September 29, 2026
Claire Vo breaks down TypeSafe AI's decision model Jev, explaining how its low cost and typed output primitives (choice, score, and boolean likelihood) enable high-speed data classification. She shares real-world production use cases, including pairwise pull-request categorization, local coding session meta-analyses, and multi-model pipelines for product insights. Vo also demonstrates how to pair fast decision models with frontier LLMs and real-time voice APIs to build responsive dashboards and interactive applications.
Key takeaways
- Claude Code and Codex store complete user turns and session history directly on your local hard drive. Read more →
- Analyzing 1,700 pull requests across ChatPRD took two minutes and cost 9 cents using fast decision models instead of heavy vector embeddings. Read more →
- Claire Vo built a real-time multimodal app in one afternoon by combining OpenAI's Realtime Voice API, Jev, and the API Ninjas quote endpoint. Read more →
- Standard frontier models generate unstructured text strings, creating high latency, unpredictable output parsing, and steep output token costs. Read more →
- Claire Vo processed 4,500 YouTube comments with TypeSafe AI's decision model Jev, replacing expensive frontier LLM calls with fast, typed classification primitives. Read more →
