Summary

RealtimeKit generates AI-powered meeting summaries from transcript data.

Models and Workers AI usage

RealtimeKit automatically selects a Workers AI model based on the estimated size of the transcript and prompts, plus an output token allowance. It currently uses these models:

Model	When used
`@cf/meta/llama-3.2-3b-instruct`	Requests that fit the Llama context budget or chunks from requests exceeding the GLM budget.
`@cf/zai-org/glm-4.7-flash`	Requests that exceed the Llama context budget but fit the GLM budget.

If a request exceeds the GLM context budget, RealtimeKit splits the transcript into chunks. It uses Llama to summarize the chunks and combine their results, which requires multiple model calls. Cloudflare may change the models or how they are selected at any time.

Both summarization and transcription contribute to Workers AI usage on your Cloudflare account. Summarization usage depends on the model and the input and output tokens across model calls. For rates, refer to Workers AI model pricing.

Turn on summarization

Set summarize_on_end: true when creating a meeting. For post-meeting summaries, also set transcribe_on_end: true so RealtimeKit generates the summary automatically after the transcript is available:

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/meetings" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Product Review",
    "transcribe_on_end": true,
    "summarize_on_end": true,
    "ai_config": {
      "transcription": {
        "language": "en-US"
      },
      "summarization": {
        "word_limit": 500,
        "text_format": "markdown",
        "summary_type": "team_meeting"
      }
    }
  }'

Configuration

Option	Type	Default	Description

REST API

Fetch summary

Refer to Fetch summary of transcripts for a session.

  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

Trigger manually

Use the Generate summary of transcripts for the session API if summarize_on_end was not set and you want to generate a summary manually after the transcript is available.

curl -X POST "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/realtime/kit/$APP_ID/sessions/$SESSION_ID/summary" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"
