Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Hark Handoff, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
Hark Handoff is a proprietary model. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.

Official launch snapshot from Hark's August 5, 2026 Handoff announcement. Hark describes Handoff as a long-horizon computer-use agent that runs in a dedicated virtual computer with a browser, file system, and terminal. Its launch compares the system on Online-Mind2Web, WebTailBench, and internal browser-use evaluations, but the published Online-Mind2Web chart is not exposed as machine-readable values and the WebTailBench/internal results use Hark's own harness. BenchLM therefore records the release without copying non-reconciled values into comparable benchmark fields.
The profile has no source-displayable benchmark row yet.
Last updated November 4, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does Hark Handoff perform overall in AI benchmarks?
Hark Handoff does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.
Does Hark Handoff have full benchmark coverage on BenchLM?
No. Hark Handoff currently has 0 source-displayable rows. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Hark Handoff?
Hark Handoff's context window is not documented in a source tied to this exact model yet. The profile leaves the value unavailable instead of borrowing a limit from an earlier family member or an unverified route. Maximum output length remains a separate field.
