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 btw?

btw is turning into an agentic R harness that no longer needs you to be in R

btw assembles context about an R session — packages, documentation, files, data frames — and hands it to an LLM through ellmer, with btw_app() as a chat interface. Over the last year it has grown well past context assembly: LLMs can document, check, test and measure coverage of a package, read CLAUDE.md and AGENTS.md as project context, fetch skills from packages or GitHub, and inspect the source of any installed namespace. Much of this is now reachable from a terminal CLI rather than only from an R prompt.

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.

btw is turning into an agentic R harness that no longer needs you to be in R

◆ Current state

btw assembles context about an R session — packages, documentation, files, data frames — and hands it to an LLM through ellmer, with btw_app() as a chat interface. Over the last year it has grown well past context assembly: LLMs can document, check, test and measure coverage of a package, read CLAUDE.md and AGENTS.md as project context, fetch skills from packages or GitHub, and inspect the source of any installed namespace. Much of this is now reachable from a terminal CLI rather than only from an R prompt.

◆ Where it's heading

The direction is from describing a session to operating on it, and from inside R to outside it. Each release adds either a tool group that lets a model do something (document, check, test, cover; read namespace source; fetch skill resources) or a CLI command that removes the need to start R first. The 1.2.0 tool renaming — session becoming sessioninfo, search becoming cran, files_read_text_file becoming files_read — reads as the naming cleanup you do when you expect a lot more tools to follow.

◆ Prediction

The CLI has been absorbing one tool family per release (skills, then pkg desc and pkg src) while the R-side tool groups stay ahead of it, so the next releases likely continue exposing existing tool groups as terminal commands rather than adding new capabilities.
