We are using the agent platform through react app.Can eleven lab's response be cached. For example

Short answer: There’s no built‑in “response cache” in the Agents Platform, but you can cache and reuse your own generated output on your side. This won’t reduce minute-based Agent billing unless you shorten the connection time.

What’s allowed

• You may store and reuse Outputs you’re able to download from the service (e.g., pre-generated audio) outside ElevenLabs, subject to the Terms and Prohibited Use Policy. (elevenlabs.io)

What it affects (and doesn’t)

• Agents voice calls are billed by connection duration. Caching the greeting (first message) doesn’t change costs if the Agent session is already connected. (help.elevenlabs.io)
• To actually reduce cost, start the Agent session only after your app finishes playing your own cached greeting (so the paid connection begins later). The React SDK’s startSession (useConversation) is what establishes the websocket/WebRTC connection. (elevenlabs.io)
• If you do use the platform’s “First message” field, it’s spoken by the Agent after connection begins; that time is billable. (elevenlabs.io)
• Additional cost optimization: periods of silence longer than 10 seconds are charged at 5% of the usual per‑minute rate (applies only while the Agent is connected). (elevenlabs.io)

Practical approach in a React app

• Pre-render or pre-generate your static greeting (text or audio) and play it locally.
• Only call startSession when you want the paid Agent connection to begin (e.g., on user interaction or after the greeting finishes). (elevenlabs.io)

If you need retention/privacy controls for stored audio/transcripts inside ElevenLabs (not caching), see Audio Saving/Retention settings; they don’t change billing. (elevenlabs.io)

No type of caching to reduce cost is provided by eleven labs?

Short answer: there’s no server‑side “response caching” feature that waives billing for repeat generations. Each new TTS generation and each agent interaction is billed per the normal pricing model.

What you can do today:

• Reuse previously generated audio via the History API instead of regenerating it (list, fetch, and download prior outputs). This lets you pay once for a clip and serve it again from your app/CDN. (elevenlabs.io)
• In Agents, costs are still per minute (and per text message in multimodal mode), but there are two built‑in optimizations: setup/prompt testing is billed at half cost, and long silent periods are billed at 5% of the usual per‑minute rate. (elevenlabs.io)
• If you use external LLMs with the Agents platform, some providers offer token caching with separate input_cache_write/read pricing; those savings (where supported) are determined by the LLM provider, not by ElevenLabs itself. (elevenlabs.io)

If you need a fixed first message, you can set/override the agent’s firstMessage, but that does not by itself reduce billing unless you pre‑generate and reuse the audio via the History API as above. (elevenlabs.io)

tell me more about reusing previously generated audio

[supple wagon]

AI-generated Answer for kishore_vb

Here are the officially supported ways to reuse previously generated audio with ElevenLabs:

• Download past generations (web)

  • Text to Speech and Voice Changer both keep a History you can open to re‑download prior outputs as MP3 or WAV. (help.elevenlabs.io)

• Reuse via API (programmatic)

  • List your generation history, fetch metadata, and download the exact audio again using the History endpoints:
    • List: GET /v1/history
    • Get item: GET /v1/history/:history_item_id
    • Get audio: GET /v1/history/:history_item_id/audio
    • Bulk download: POST /v1/history/download
  • Text-to-speech calls return a history_item_id (there can be a slight delay before it appears in history). (elevenlabs.io)

• Studio (long‑form) reuse

  • Generation history per paragraph lets you listen to, restore, and download earlier takes; locking prevents accidental changes. The Play button uses already‑generated audio without consuming credits again. You can also access prior Exports for chapters/projects. (help.elevenlabs.io)

• Embedding pre‑generated audio

  • Audio Native can embed pre‑generated content from a Studio project on your website. (elevenlabs.io)

• Make sure history is retained

  • If you need to fetch past outputs later, keep enable_logging=true on API requests. Setting enable_logging=false activates zero‑retention mode and disables history features (including request stitching). (elevenlabs.io)

• Licensing (can I keep using it?)

  • Content generated during a paid subscription can be used commercially without attribution; you keep that license even after the subscription ends. Access to files in your account isn’t guaranteed on the free tier, so download what you need. (help.elevenlabs.io)

• Cost notes (no “preview” mode)

  • Credit is charged on generation, not on download; there’s no download‑based or “preview without credits” option. Two free regenerations are available on the website UI (not via API) under specific conditions. (help.elevenlabs.io)

• If you need bit‑for‑bit repeatability

  • You can pass a seed to TTS for best‑effort determinism when re‑generating, but exact identity isn’t guaranteed; reuse the saved audio if you need it identical. (elevenlabs.io)

If you’re using the Agents platform in a React app and want a repeated greeting or message, the documented approach is to generate it once (TTS or Studio), store it, and play that asset in your app rather than regenerating it

any recommendations to reduce the cost associated with eleven labs in agents platform

[supple wagon]

AI-generated Answer for kishore_vb

Here are cost-reduction tactics that are explicitly supported for ElevenLabs Agents:

• Use the built‑in 95% discount during silence. If the conversation is silent for >10 seconds, billing drops to 5% of the normal per‑minute rate. Avoid filler speech; let the agent pause so these silent windows trigger. (elevenlabs.io)
• Keep calls short and end decisively. Charges are based on connection duration (from connect until you end/close). Add the End Call system tool so the agent hangs up as soon as the task is done. (help.elevenlabs.io)
• Switch to text‑only when voice isn’t needed. Text‑only mode bills per message (fractions of a cent) instead of per‑minute audio. You can toggle textOnly in the React SDK or use First message/Prompt overrides to tailor flows. (elevenlabs.io)
• Optimize LLM spend (passed through separately). Choose lower‑cost models when acceptable, tighten prompts, use retrieval so prompts are smaller, and call tools intelligently. (elevenlabs.io)
• Reuse previously generated audio for fixed intros (e.g., a welcome line). Pre‑generate via TTS, then download and play it client‑side before starting the agent session. Use the History List/Download APIs; keep enable_logging=true on TTS requests so items appear in history. (elevenlabs.io)
• Deliver the legally required disclosure as a pre‑recorded clip before connecting to Agents. This both meets policy and avoids billed agent minutes during the disclosure. (elevenlabs.io)
• Use Skip Turn when users ask to “hold on.” It suppresses unnecessary agent speech and helps you benefit from silence billing instead of filling time. (elevenlabs.io)
• Disable Burst Pricing unless you truly need overflow capacity. Burst minutes are billed at 2× the normal rate during spikes. (elevenlabs.io)
• Choose the right plan. Business annual pricing includes 13,750 agent minutes and extra minutes at $0.08/min; it’s cheaper than monthly ($0.096/min). (elevenlabs.io)
• Protect your credits. Enable authentication on agents so unknown clients can’t connect and consume minutes. (elevenlabs.io)
• Do iteration in “Setup & Prompt Testing” mode. Those test calls are billed at half cost while you tune prompts and logic. (help.elevenlabs.io)

I'm using TSS and STT from eleven labs from my server. Can I also use the KB of eleven labs from my server?

Without the agents platform?
