The useful part of this video is the setup detail: an explicit search backend you picked months ago still wins, so some users won't get the change at all. Source video "Perplexity Just Made Hermes Agent WAY Better" by **Julian Goldie SEO** — [Watch on YouTube →](https://youtube.com/watch?v=TB2VsoCSbLs) ## What changed - **Portal users get it by default.** On the Nous Portal route, Hermes' `web_search` tool now goes through Nous's [Tool Gateway](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway) to Perplexity. Nous and Perplexity announced this on 2026-09-24; the video quotes Perplexity at a ~160 ms median and 95% of searches under 230 ms. - **Page reading hasn't changed.** According to the video, `web_extract` (full-page reads) stays on Firecrawl. If a managed Perplexity call fails, that one call falls back to another backend. - **Bring-your-own-key still works.** The `perplexity` backend with `PERPLEXITY_API_KEY` is a documented option. The video cites Perplexity's docs for the minimum version, which the auto-captions render ambiguously ("0.2, 1.1"). Update to the current release rather than relying on that number. - **Only search changes, not the model.** Your reasoning model stays whatever you picked. ## The setting that blocks it — confirmed in the docs The Hermes docs are explicit: *"The runtime always uses the stored web.backend selection (set via hermes tools; nous routes through the managed Tool Gateway)."* Auto-detection only happens if you've never picked a backend. So if you set `firecrawl`, `tavily` or `exa` in the past, you are still on it. ``` # update first — the change landed 2026-09-24 hermes update # then pick the Nous-managed web search row hermes tools ``` Or check `~/.hermes/config.yaml` directly: ``` web: backend: nous # managed Tool Gateway route # search_backend / extract_backend override per capability — remove old ones ``` The docs also list per-capability keys (`web.search_backend`, `web.extract_backend`). An old `search_backend` line overrides the main backend for searches, so remove it too. Source: [Hermes configuration → Web Search Backends](https://hermes-agent.nousresearch.com/docs/user-guide/configuration). ## Tips from the video worth keeping - **Check who served the search.** The video cites an open GitHub report (2026-09-25) from a Portal user whose searches were quietly falling back to another backend while still reporting success. The tool result names the backend. If it doesn't say Perplexity, you aren't on fast search. - **Match the search to the job.** Perplexity recommends fast search for everyday agent lookups and its default search for hard, long-tail research. Fast search scored slightly lower on rare questions in its internal tests. - **Finding isn't verifying.** Ask the agent for the search result *and* the exact line from the page it used. - **Watch what reaches memory.** Hermes memory persists, so a bad source saved once gets reused. Keep the source attached to saved facts (see [Hermes memory](https://openclawdatabase.com/hermes/memory/)). The last half of the video promotes a paid community; this page covers only the technical content. ## More Hermes news [▶ Hermes desktop's new features, verified: Bot Mode, HUD, voice, "Hey Hermes" and cron continuity 2026-09-25](https://openclawdatabase.com/news/videos/2026-09-25-hermes-desktop-bot-mode-hud-wake-word/) [▶ Hermes computer-use: giving each agent its own Linux desktop in a container 2026-09-24](https://openclawdatabase.com/news/videos/2026-09-24-hermes-computer-use-screen-desktop/) [▶ Serena as an MCP server for Hermes: LSP-powered find-references and safe renames 2026-09-16](https://openclawdatabase.com/news/videos/2026-09-16-serena-mcp-hermes-agent-semantic-code/) [▶ Running a Hermes agent in a real business: permissioning, skills and the trust ladder 2026-09-10](https://openclawdatabase.com/news/videos/2026-09-10-hermes-agent-real-business-lessons/) [▶ Hermes /loop: recurring agent wake-ups with real stop conditions 2026-08-18](https://openclawdatabase.com/news/videos/2026-08-18-hermes-loop-recurring-agent-tasks/) [▶ DeepSeek V4 Pro 0813 driving Hermes agent: agentic benchmarks jump, cost stays low 2026-08-12](https://openclawdatabase.com/news/videos/2026-08-12-deepseek-v4-pro-0813-hermes-agent-test/) [See all Hermes news →](https://openclawdatabase.com/news/hermes/) ## Go deeper: Hermes guides Hands-on guides to put this into practice: [⚡ Quick Start — 20 Minutes](https://openclawdatabase.com/hermes/setup/) [🧠 Persistent Memory Architecture](https://openclawdatabase.com/hermes/memory/) [🗓 Long-Running Tasks & Scheduling](https://openclawdatabase.com/hermes/tasks/) [⚖️ Hermes vs OpenClaw](https://openclawdatabase.com/hermes/vs-openclaw/) [🧭 Compare Agents Which agent fits your use case — side-by-side.](https://openclawdatabase.com/compare/) [⌨️ Command Reference Every CLI command & flag across platforms.](https://openclawdatabase.com/commands/)
