What is mlr3hyperband?

Hyperband tuning for mlr3, now built on an asynchronous backend it treats as mandatory

mlr3hyperband supplies successive-halving and Hyperband optimizers to the mlr3 tuning stack. Its recent releases are dominated by ecosystem plumbing rather than new search algorithms: a hard floor of `rush` 1.0.0, alignment with mlr3 1.7.2, and a move onto the ecosystem's new base logger. The last genuinely new optimizer was `OptimizerAsyncSuccessiveHalving` in 1.0.0.

What is Snorkel AI?

Snorkel has stopped labeling data and started defining what agent competence means.

The output is a research and benchmarking program, not a release feed. Recent work argues that single-episode benchmarks measure the wrong thing: agents should be scored across dependent states, tool calls, simulated users, approval rules, and learning carried between tasks. Concrete artifacts back the argument — Senior SWE-Bench with 100 tasks from real pull requests and half the set held private, GDPval+ for professional reasoning, and collaboration on Agents' Last Exam with Berkeley RDI. Alongside these, Snorkel publishes head-to-head evaluations of frontier model releases and hosts a reading group that surfaces outside research.

Hyperband tuning for mlr3, now built on an asynchronous backend it treats as mandatory

◆ Current state

mlr3hyperband supplies successive-halving and Hyperband optimizers to the mlr3 tuning stack. Its recent releases are dominated by ecosystem plumbing rather than new search algorithms: a hard floor of `rush` 1.0.0, alignment with mlr3 1.7.2, and a move onto the ecosystem's new base logger. The last genuinely new optimizer was `OptimizerAsyncSuccessiveHalving` in 1.0.0.

◆ Where it's heading

The package has finished a transition from synchronous tuning to a distributed one and is now consolidating it. 1.1.1 raised the `rush` minimum to 1.0.0 and deleted every compatibility workaround for older versions, which ends the period where the async backend was optional. Logging moved the same way in 1.1.0: `bbotk`, `mlr3tuning` and `mlr3hyperband` now log through a child of a shared `mlr3` logger rather than their own.

◆ Prediction

With the compatibility layer gone, the next release is more likely to extend async optimizers than to revisit the backend, since the recent versions spent their changes on removing optionality rather than adding surface. The entries give no signal on which optimizer comes next.

Snorkel has stopped labeling data and started defining what agent competence means.

◆ Current state

The output is a research and benchmarking program, not a release feed. Recent work argues that single-episode benchmarks measure the wrong thing: agents should be scored across dependent states, tool calls, simulated users, approval rules, and learning carried between tasks. Concrete artifacts back the argument — Senior SWE-Bench with 100 tasks from real pull requests and half the set held private, GDPval+ for professional reasoning, and collaboration on Agents' Last Exam with Berkeley RDI. Alongside these, Snorkel publishes head-to-head evaluations of frontier model releases and hosts a reading group that surfaces outside research.

◆ Where it's heading

Snorkel is moving from evaluation-as-scoring to evaluation-as-training signal: the milestone framing scores intermediate progress, the continual-learning thread treats improvement across a task sequence as the measured quantity, and the newest reading-group post pushes further upstream still, into how much a reasoning model should be trained before it is tested. Publishing benchmarks with private splits and running public model comparisons builds the position that Snorkel is the neutral scorer, which is what makes the enterprise environments business defensible. The through-line is that measurement, not model capability, is the bottleneck.

◆ Prediction

Expect the milestone and continual-learning threads to converge into a named benchmark or environment suite with the same public-private split as Senior SWE-Bench. The feed carries research, talks, and reading-group recaps rather than platform releases, so it does not indicate what ships in the product.
