What is Khoj?

Khoj gave its assistant long-term memory, then started winding down its own cloud.

The 2.0 beta line is doing two things at once. In February it gave Khoj long-term memories, moving the assistant from per-conversation context to knowledge that persists across sessions. Six weeks later it began deprecating Khoj cloud — a banner warning hosted users, and the subscribe option removed from the web app's settings page. The same release upgraded the web app to Next.js 15 and fixed the research agent stopping earlier than it should.

What is Perplexity?

Perplexity is selling access to other people's models, and now repricing them weekly.

The Gateway API put Anthropic, OpenAI, Google, xAI, and Perplexity models behind one endpoint reachable with an existing Perplexity key, and the MCP server became a remote service hosted by Perplexity with no local installation. Since then the traffic has been commercial rather than structural: GPT-5.6 price cuts, a Sol Fast mode, and successive preset re-pointings — low and fast both now run openai/gpt-5.6-luna, with the fast preset carrying priority processing at twice standard token prices. Frozen configurations have to be updated by hand each time.

Khoj gave its assistant long-term memory, then started winding down its own cloud.

◆ Current state

The 2.0 beta line is doing two things at once. In February it gave Khoj long-term memories, moving the assistant from per-conversation context to knowledge that persists across sessions. Six weeks later it began deprecating Khoj cloud — a banner warning hosted users, and the subscribe option removed from the web app's settings page. The same release upgraded the web app to Next.js 15 and fixed the research agent stopping earlier than it should.

◆ Where it's heading

Khoj is consolidating around the self-hosted product and the model layer beneath it, and stepping back from running the hosted service. Model support has been broadening steadily — Gemini Pro 3, Minimax M2, Nano Banana image editing, configurable fallback models with admin-set priority — while Stability AI image generation was dropped. The client work follows the same logic: Obsidian batch sync, file query filter autocomplete, reference copying, all aimed at people running their own instance against their own files.

◆ Prediction

With subscriptions already disabled and a deprecation banner live, the next step for the hosted service is a shutdown date. The entries stop in late March 2026, so whether 2.0 has left beta since is not visible here.

Perplexity is selling access to other people's models, and now repricing them weekly.

◆ Current state

The Gateway API put Anthropic, OpenAI, Google, xAI, and Perplexity models behind one endpoint reachable with an existing Perplexity key, and the MCP server became a remote service hosted by Perplexity with no local installation. Since then the traffic has been commercial rather than structural: GPT-5.6 price cuts, a Sol Fast mode, and successive preset re-pointings — low and fast both now run openai/gpt-5.6-luna, with the fast preset carrying priority processing at twice standard token prices. Frozen configurations have to be updated by hand each time.

◆ Where it's heading

Perplexity is behaving like an infrastructure vendor rather than an answer engine: the differentiator is the credential and the routing, not the model. The preset churn is the visible cost of that position — when the models underneath are someone else's, keeping a named tier meaningful means re-pointing it whenever the market moves, and passing the migration work to customers who pinned a configuration. Inline citations across the search-backed presets remain the one capability that is distinctly Perplexity's own.

◆ Prediction

Expect the preset re-pointings to keep arriving at this cadence and the priority-processing tier to spread beyond the fast preset, since a 2x price band is easier to extend than to justify on one preset alone.
