What is Alhena AI?

Alhena is slicing one benchmark study into a month of posts, one finding each.

Alhena AI sells shopping agents for ecommerce, and its feed is currently one piece of research being published a finding at a time. The 2026 stress test ran fifteen live AI shopping agents through real storefronts as ordinary shoppers: all fifteen could answer, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Four of the last five posts restate those same numbers from a different angle — the answer-to-act gap, memory, and now a taxonomy separating personalisation engines, AI search and agentic assistants by which ceiling each hits.

What is mlr3?

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.

Alhena is slicing one benchmark study into a month of posts, one finding each.

◆ Current state

Alhena AI sells shopping agents for ecommerce, and its feed is currently one piece of research being published a finding at a time. The 2026 stress test ran fifteen live AI shopping agents through real storefronts as ordinary shoppers: all fifteen could answer, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Four of the last five posts restate those same numbers from a different angle — the answer-to-act gap, memory, and now a taxonomy separating personalisation engines, AI search and agentic assistants by which ceiling each hits.

◆ Where it's heading

The taxonomy post is the tell: by naming three technologies that share a chat box and assigning each a hard ceiling — Recommend, Sell, Act and Remember — Alhena turns its benchmark into a category ladder with its own product at the top rung. Around that sit dated vertical censuses separating shipped assistants from announced intent, an attribution model, and comparison pages against AI visibility tools including Profound. None of this is product news; the last shipped features in the feed were the embeddable agents in July.

◆ Prediction

Expect the study to keep yielding one post per finding until it is exhausted, then a refreshed census or a second vertical on the same template; actual release notes will keep arriving only as launch posts between research runs.

mlr3 is hardening the seams where its abstractions meet real learners

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
