Alhena AI vs Snorkel AI
A side-by-side editorial comparison of Alhena AI and Snorkel AI — release velocity, themes, recent moves, and the top alternatives to consider.
Alhena AI vs Snorkel AI: at a glance
What is Alhena AI?
A vendor running a public benchmark on its own category, and publishing where everyone fails.
Alhena AI's feed is a research blog, not a changelog, but it is unusually structured for one: since late July it has run a single continuing study in which 15 live AI shopping agents are tested as ordinary shoppers on real storefronts. The findings are consistent and unflattering to the category - all 15 can answer questions, 9 can sell, 4 can complete a return or order change, and 1 remembers a shopper across sessions. Recent instalments break the results down by 11 verticals and by a specific task, foundation shade matching from a selfie, where five agents ignored the image entirely.
What is Snorkel AI?
Snorkel is building the scoreboard for agents that have to keep working, not just answer.
The feed is a research and benchmark channel, not a release channel. It alternates Reading Group write-ups of outside papers with Snorkel's own evaluation artifacts — Senior SWE-Bench, GDPval+ model runs, and now a Continual Learning Bench — plus per-model analyses of frontier releases. The recurring argument across all of it is that single-episode benchmarks measure the wrong thing for deployed agents.

Alhena AI
5.0AI-ASSISTANTS
A vendor running a public benchmark on its own category, and publishing where everyone fails.
◆ Current state
Alhena AI's feed is a research blog, not a changelog, but it is unusually structured for one: since late July it has run a single continuing study in which 15 live AI shopping agents are tested as ordinary shoppers on real storefronts. The findings are consistent and unflattering to the category - all 15 can answer questions, 9 can sell, 4 can complete a return or order change, and 1 remembers a shopper across sessions. Recent instalments break the results down by 11 verticals and by a specific task, foundation shade matching from a selfie, where five agents ignored the image entirely.
◆ Where it's heading
The blog is building a capability ladder - Answer, Recommend, Sell, Act, Remember - and using it to argue that architecture, not category difficulty, decides where an agent stops. That framing does competitive work: it defines the axis on which agents are compared, places memory and task completion at the top, and reports that almost nothing on the market reaches them. Nothing here describes Alhena's own product releases, so the feed shows the argument the company is making rather than what it is shipping.
◆ Prediction
The benchmark series looks set to continue with further vertical and task cuts against the same 15-agent panel. A refreshed run showing movement on the Act and Remember rungs would be the natural next instalment, though these entries do not say when it is due.
Snorkel AI
5.0AI-ASSISTANTS
Snorkel is building the scoreboard for agents that have to keep working, not just answer.
◆ Current state
The feed is a research and benchmark channel, not a release channel. It alternates Reading Group write-ups of outside papers with Snorkel's own evaluation artifacts — Senior SWE-Bench, GDPval+ model runs, and now a Continual Learning Bench — plus per-model analyses of frontier releases. The recurring argument across all of it is that single-episode benchmarks measure the wrong thing for deployed agents.
◆ Where it's heading
Snorkel is staking out evaluation of long-horizon, experience-accumulating agent work: milestone-based scoring, enterprise environments rather than thin task slices, and continual learning across task sequences. Each benchmark it publishes doubles as an argument for the expert-data business underneath, since realistic environments and milestone labels are exactly what its labeling operation produces. The company is positioning as the measurement layer frontier labs hill-climb on.
◆ Prediction
Expect the continual-learning and milestone threads to converge into a single evaluated environment suite, with frontier-model results published against it in the same format as the existing GDPval+ and Senior SWE-Bench runs.
