Use Hermes Fast Mode with Cost and Latency Controls

Hermes can request a provider's faster processing tier for a conversation with /fast. This can shorten model-response latency, but it does not make tools, builds, uploads, or external services run faster. It may also change billing, eligibility, or fallback behavior depending on the active provider.

Know what the switch changes

Use /fast fast to request the supported priority tier, /fast normal to return to standard processing, and /fast status to inspect the current setting. The command currently maps to provider capabilities such as OpenAI Priority Processing and Anthropic Fast Mode; unsupported providers may not offer an equivalent path.

Fast mode is most useful when human waiting time matters: live incident response, an interactive coding loop, a customer-facing drafting session, or a short approval window. It is usually poor value for unattended cron jobs, long-running builds, bulk generation, or work dominated by network and tool execution.

Decision checklist

• Confirm the active provider supports a priority tier.
• Check whether priority requests have a different price or quota.
• Separate model latency from tool and deployment latency.
• Use fast mode for a bounded session rather than as an unexplained default.
• Return to normal mode after the time-sensitive window.
• Keep verification and safety gates identical in both modes.
• Record the mode when comparing latency or cost.

Pitfalls

• Assuming /fast accelerates terminal commands or browser navigation.
• Enabling a higher-cost tier for overnight or batch work.
• Comparing two runs without recording provider, model, prompt size, and cache state.
• Treating a fast response as a more accurate response.
• Forgetting that a fallback provider may have different priority semantics.

Verification steps

1. Run /fast status and record the provider, model, and current mode.
2. Enable fast mode for a harmless, representative prompt.
3. Confirm the command reports the requested state instead of assuming support.
4. Compare several similar turns; one sample is not a useful benchmark.
5. Check provider usage or billing telemetry when available.
6. Run the same tests and artifact checks used in normal mode.
7. Return to /fast normal when the latency-sensitive work is complete.
