About Halv
Key Strengths
- Desktop workspace that runs Claude Code, Codex, Kimi and GLM on your existing subscriptions, with up to 32 live terminal panes
- Local context compression, command-output filtering and a code index (Crux) cut repeated context; a live savings meter shows the effect
- Published benchmark data: on 14 SWE-rebench tasks Codex plus Halv kept 25/42 passes at 57.1% lower recorded cost
Limitations to Consider
- That benchmark is an interim, self-published result (14 of 111 planned tasks), and Halv used 3.49x as many tokens; savings came from routing to cheaper models
- Card required for the 7-day trial, then a $10/month subscription on top of your agent plans
- Your model provider still gets prompts and context, and the providers still control your usage limits
