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 Perplexity?

Perplexity is selling access to other people's models, not just its own answers.

The recent changelog is almost entirely API-side. A Gateway API fronts open-weight models behind one endpoint that speaks both OpenAI Chat Completions and Anthropic Messages, a remote MCP server exposes Perplexity to outside agents, and the Agent API keeps absorbing new models. Consumer-facing notes — preset tuning, inline citations for research presets — read as maintenance beside that.

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.

Perplexity is selling access to other people's models, not just its own answers.

◆ Current state

The recent changelog is almost entirely API-side. A Gateway API fronts open-weight models behind one endpoint that speaks both OpenAI Chat Completions and Anthropic Messages, a remote MCP server exposes Perplexity to outside agents, and the Agent API keeps absorbing new models. Consumer-facing notes — preset tuning, inline citations for research presets — read as maintenance beside that.

◆ Where it's heading

The product is splitting in two: an answer engine for end users and an inference-and-routing layer for developers. Price moves in the same window, a GPT-5.6 cut and a faster low-cost mode, put Perplexity in a cost-per-token argument rather than an answer-quality one. Building the gateway to mimic the two dominant API dialects makes the switching cost it removes its own.

◆ Prediction

Expect more hosted open-weight models behind the gateway and firmer pricing tiers, with the remote MCP server moving from a listed feature to a documented, permissioned surface.
