Benchmark ledger
Every result says who ran the test. For this model, Hark ran all 2.
| Benchmark | Score | On a 0–100 scale | Who ran it | Use in ranking |
|---|---|---|---|---|
| Hark internal alignment benchmarkScore · Hark’s own internal evaluation; method not published | 93.8% | Reported by Hark | Shown only | |
| Hark internal browsing benchmarkTasks completed · Hark’s own harness; 478 tasks across 238 websites | 82% | Reported by Hark | Shown only |
Outlined bars are lab-reported. Filled bars are benchmark-run or independent. Bars run 0–100.
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 2, 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 2 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 November 12, 2026 Handoff² announcement. Hark names the model Handoff², the successor to Handoff, and describes it as a computer-use agent that handles web tasks end to end. Hark reports that Handoff² completes 82% of the 478 tasks across 238 websites in its internal browsing benchmark, up from 73% for Hark Handoff, while taking 46% less time per task. Hark also reports 93.8% on its internal alignment benchmark, up from 90.3% for Hark Handoff. Hark says Handoff² comes within 5 points of Opus 5.5 max on the browsing benchmark while running 2x faster, with Opus run in the same harness, but it does not give the Opus score. Both tests are unnamed internal evaluations that Hark ran in its own harness, and Hark Handoff ran in its original harness, so BenchLM does not copy these values into comparable benchmark fields.
Hark Handoff 2 sits in the Hark Handoff family with Hark Handoff. Its explicit predecessor is Hark Handoff. The profile has no source-displayable benchmark row yet.

Questions
How does Hark Handoff 2 perform overall in AI benchmarks?
Hark Handoff 2 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.
Which sibling models are related to Hark Handoff 2?
Hark Handoff 2 belongs to the Hark Handoff family. Related tracked variants include Hark Handoff. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Hark Handoff 2 have full benchmark coverage on BenchLM?
No. Hark Handoff 2 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 2?
Hark Handoff 2'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.
