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 NVIDIA NeMo?

NeMo split itself apart: the flagship repo is now a speech toolkit and nothing else.

NeMo has spent the last six months on a controlled demolition. The 2.7.0 notes warned that avlm, diffusion, llm, multimodal, nlp, speechlm, vision and vlm collections would be removed; NeMo Speech 3.0 executed it, splitting the repository, renaming it to NVIDIA-NeMo/Speech and moving everything non-speech to sibling repos. The release removed 800k lines of deprecated code, moved to uv for installs, cut dependencies and shipped lighter containers. Patch releases in between were security fixes and CUDA binding repairs.

Alhena AI vs NVIDIA NeMo: 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.

3.8

NeMo split itself apart: the flagship repo is now a speech toolkit and nothing else.

◆ Current state

NeMo has spent the last six months on a controlled demolition. The 2.7.0 notes warned that avlm, diffusion, llm, multimodal, nlp, speechlm, vision and vlm collections would be removed; NeMo Speech 3.0 executed it, splitting the repository, renaming it to NVIDIA-NeMo/Speech and moving everything non-speech to sibling repos. The release removed 800k lines of deprecated code, moved to uv for installs, cut dependencies and shipped lighter containers. Patch releases in between were security fixes and CUDA binding repairs.

◆ Where it's heading

This is a scope decision, not a cleanup. NeMo is trading its position as a general-purpose model framework for a defensible one as the speech toolkit — ASR, TTS, speaker tasks and SpeechLM — and accepting a hard migration for everyone else. The feature work that did ship in 2.7.0 points the same way: streaming speech translation, per-stream phrase boosting, and new streaming ASR and multilingual TTS models.

◆ Prediction

With the split done, expect the next releases to be speech-model drops rather than framework changes, and the separated repos to start versioning independently.
