Enable Fast Mode for Priority Models
TL;DR
Added a /fast toggle to route requests through priority queues for OpenAI and Anthropic models, significantly reducing latency for supported models like GPT-5.4 and Claude.
## What changed Hermes Agent added a /fast toggle on May 18, 2026. The command routes requests for OpenAI and Anthropic models through priority queues. Supported models include GPT-5.4 and Claude.
The change reduces latency on time-sensitive tasks. Users activate it inside any connected chat on Telegram, Discord, or Slack. No new configuration files or provider switches are required.
## Why it matters Vibe Builders often chain agents into live workflows that need quick replies. Priority routing keeps responses fast even when the main queue is busy. This matters for tasks that feed into Notion updates or Zapier triggers where delays break the flow.
The move pressures pure SaaS agents that charge extra for speed tiers. It also bets that self-hosted users will accept a small extra cost on their API keys to avoid switching tools mid-task.
## How to use it Open a chat with your Hermes Agent instance. Type /fast followed by your request. The toggle stays active for that session until you send /fast again to disable it.
No plan upgrade is needed. The feature works with any OpenAI or Anthropic key you already supply through the CLI or config. Test it first on a short prompt to confirm the latency drop before using it on longer agent runs.
## Watch for Confirm the bet if average response times drop below three seconds on priority models during peak hours. Watch for queue throttling or higher token costs that erase the speed gain. The next expected move is similar priority handling for local models via Ollama or a new background task queue.
Harsh’s take
For a solo Vibe Builder running a business in 2026, Fast Mode is a practical patch for the always-on VPS requirement. You still pay for the server and the API calls, but you now get usable speed without moving everything to a hosted agent that bills monthly.
The honest trade-off is added complexity in your chat commands. One extra toggle means one more thing to remember when you hand tasks to the agent from your phone. If you forget it, you sit in the normal queue and lose the benefit you installed the tool for.
Do this now: add a short test workflow that uses /fast on a recurring Zapier handoff and measure the time saved over a week. Drop the toggle if the difference stays under two seconds.

- FeatureIntegrate LSP semantic diagnostics for file edits
The agent now runs a language server against edited files to catch type errors and undefined symbols immediately. This provides deeper analysis than basic linting for `write_file` and `patch` operations.
- App UpdateLaunch native Windows support in early beta
Hermes now runs natively on Windows via cmd.exe and PowerShell without requiring WSL. Includes a dedicated PowerShell installer and fixes for path normalization and process management.
- IntegrationAdd native support for LINE and SimpleX Chat
Hermes expands its messaging reach to 22 platforms with the addition of LINE and the privacy-focused SimpleX Chat. Both are implemented as first-class messaging adapters.
