Alhena AI
Alhena is slicing one benchmark study into a month of posts, one finding each.
A side-by-side editorial comparison of mlr3 and Snorkel AI — release velocity, themes, recent moves, and the top alternatives to consider.
mlr3 is hardening the seams where its abstractions meet real learners
Releases arrive every few weeks and read as a systematic audit of the Learner interface. Recent versions added a native_model binding and a predict_raw flag so users can reach the underlying package's model and raw prediction, gave encapsulated learners a wall-clock deadline alongside the existing timeout, and removed the deprecated Task$divide(). A run of fixes addresses correctness at the boundary - factor level ordering that inverted binary probabilities, fallback learners losing state, misaligned probability columns.
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.

The framework is maturing from wrapping models to being accountable for what happens when wrapping goes wrong. Structured Mlr3Error and Mlr3Warning classes, conditions stored on the learner log, and messages replaced by conditions all point at making failures programmatically inspectable rather than printed. In parallel, escape hatches to the upstream model are being formalised instead of left to users digging into internals.
Expect the remaining deprecated surface to follow Task$divide() out, and further work on encapsulation and fallback behaviour, which is where most recent fixes have clustered. The raw and native_model accessors suggest more of the upstream model will be surfaced deliberately.

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.
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.
