What is Alhena AI?

Alhena is building the scoreboard for shopping agents it also competes in.

The feed has consolidated around one piece of original research: a 2026 stress test running fifteen live AI shopping agents through real storefronts as ordinary shoppers. The headline numbers repeat across several posts — all fifteen could answer questions, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Around that sit vertical censuses of who is actually live in health and wellness retail, an attribution model for measuring agents, and comparison pages against AI visibility platforms including Profound.

What is ONNX Runtime?

ONNX Runtime is dismantling itself into plug-ins — CUDA is now the one that ships separately.

ONNX Runtime is running two release tracks at once: the numbered core releases (1.25 through 1.29) and a growing set of separately versioned plug-in execution providers. WebGPU broke out first in May, and CUDA has now followed with its own 0.1.0. The core releases in between are dominated by security hardening, opset upgrades and deprecation notices rather than new capability.

Alhena AI vs ONNX Runtime: editorial side-by-side

5.0

Alhena is building the scoreboard for shopping agents it also competes in.

◆ Current state

The feed has consolidated around one piece of original research: a 2026 stress test running fifteen live AI shopping agents through real storefronts as ordinary shoppers. The headline numbers repeat across several posts — all fifteen could answer questions, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Around that sit vertical censuses of who is actually live in health and wellness retail, an attribution model for measuring agents, and comparison pages against AI visibility platforms including Profound.

◆ Where it's heading

Alhena is defining the category's measuring stick and choosing metrics where most competitors fail — acting rather than answering, and remembering across sessions. Publishing a dated census that separates shipped assistants from announced intent serves the same purpose: it establishes Alhena as the arbiter of what counts as live. The vertical focus on supplements and wellness, with its FDA claims boundary and subscription economics, looks like a deliberately chosen beachhead rather than broad retail coverage.

◆ Prediction

Expect the stress test to become a recurring dated benchmark with more agents and more verticals, and for the act-and-remember gap it identifies to be positioned as what Alhena's own product closes.

7.5

ONNX Runtime is dismantling itself into plug-ins — CUDA is now the one that ships separately.

◆ Current state

ONNX Runtime is running two release tracks at once: the numbered core releases (1.25 through 1.29) and a growing set of separately versioned plug-in execution providers. WebGPU broke out first in May, and CUDA has now followed with its own 0.1.0. The core releases in between are dominated by security hardening, opset upgrades and deprecation notices rather than new capability.

◆ Where it's heading

The direction is a smaller core binary with accelerators attached at runtime. The 1.26 notes stated the intent outright — CUDA moving to a dedicated execution provider rather than a package shipped from core — and 0.1.0 delivers it, with version-gated callbacks maintaining compatibility back to 1.24.4. Alongside that, the deprecation list keeps growing: CUDA 11, then CUDA 12, WebGL and JSEP, ArmNN, the duktape WGSL generator. Web inference is being consolidated onto WebGPU and native inference onto plug-ins.

◆ Prediction

Expect the plug-in EPs to take over release cadence from the core, with CUDA 12 removed in 1.27 as announced and further backends following WebGPU and CUDA out of the main binary.
