TypeSafe Jev Ecosystem: Six GitHub Projects Spanning Browser Agents and Trading Bots
alexcovo_eth · x · 2026-09-18
Developer @studioyebisu curated six practical GitHub projects built around TypeSafe's Jev model, noting heavy usage in fast-decision scenarios like Computer Use and fully automated trading. The official waitlist clears in about a day, or you can call it directly via Vercel AI Gateway as Model: typesafe-ai/jev.
The projects:
- browser-use/jev-ultrafast: a browser agent with a dynamic, indexed action space — Jev picks operations and elements, with a small LLM writing text only for TYPETEXT; it booked a Zurich→London flight on Google Flights in 7.1s (2.9k stars).
- TheoLeeCJ/openjev: an independent project replicating the official model's I/O patterns with open models, runnable on local GPUs.
- vinnylarouge/jevlike: trains a Jev-like candidate-selection model on custom data; not yet practical but interesting.
- jarrodwatts/jev-trader: a trading bot using Jev for Kuru MON-USDC decisions on Monad, dry-run by default, no profitability guarantee.
- Anil-matcha/awesome-jev-by-typesafe: community collection of Jev usage patterns, prompts, starter code and examples.
- awlevin/typesafe-computer-use: OCR-based screen reading to decide the next click.
