DeepSeek Chat Model : Create summaries and key points

Watch out for

Supadata.ai may fail on private or age-restricted videos so add a check for empty transcript responses before calling the LLM.
DeepSeek rate limits can block the run, add exponential backoff logic to your HTTP request node.
Google Sheets API quotas are strict per minute, insert a small delay between updates to avoid 429 errors.
LLM outputs might contain markdown formatting that breaks sheet cells, strip all asterisks and hashes in a pre-processing step.
