- Hark launched its computer use agent "Handoff," which it claims outperforms GPT-5.4 and Opus 4.8
- Hark raised $700 million in Series A funding in May, ahead of a planned summer release
Why it matters: Hark enters the competitive computer-use agent space with a $700M Series A war chest and unverified benchmark claims against frontier models from OpenAI and Anthropic. The summer release will be the first chance to test whether Hark's claimed performance edge holds in practice.
