Text Analytics pricing

Text Analytics is an AI service that uncovers insights such as sentiment, entities, and key phrases in unstructured text. Text Analytics includes five main functions: Sentiment Analysis, Key Phrase Extraction, Language Detection, Named Entity Recognition, and Question Answering.

Text Analytics for health uses natural language processing to find and label information in unstructured clinical documents. There is no charge to use Text Analytics for health during public preview. This is a gated feature; learn more about the gating process here. Pricing will be released when the feature goes GA.

Frequently asked questions

  • In the S tier, the service is billed for only the amount of Text Records submitted to the service.
  • Usage is throttled if the transaction limit is reached on the Free tier. Customers cannot accrue overages on the free tier.
  • Let’s say an API call performs both sentiment analysis and key-phrase extraction on 1,000 documents, that will count for 2,000 transactions (2 × 1,000 documents). The maximum size of a single document is 5,120 characters as measured by StringInfo.LengthInTextElements. If a document has more than 5,120 chars then we do not process that specific document and show invalid document as the error. If a request has multiple documents, then we process all documents which are less than 5,120 characters. S0-S4 pricing tiers are now deprecated and you are encouraged to switch to S tier.
  • If the usage on the S0-S4 tier is exceeded, the account starts to accrue overages. These overages are billed on a monthly basis and are calculated at the rate specified for each tier. S0-S4 pricing tiers are now deprecated and you are encouraged to switch to S tier.
  • You may upgrade to a higher tier at any time. Billing rate and included quantities corresponding to the higher tier will begin immediately.
  • A text record in the S tier contains up to 1,000 characters as measured by StringInfo.LengthInTextElements. If an input document into the text analytics API is more than 1,000 characters, it counts as one text record for each unit of 1,000 characters. For instance, if an input document sent to the API contains 7,500 characters, it would count as 8 text records. If an input document sent to the API contains 500 characters, it would count as 1 text record. If two documents are submitted, one document of 500 characters and one document of 1,200 characters, then the service would be billed for three text records in total: one record for the 500 character document and two text records for the 1,200 character document. You can check your text records usage in your Text Analytics resource in Azure portal under Monitoring > Metrics > Processed Text Records.
  • Standard pricing (S instance) is text records-based pricing and enables you to use the latest capabilities of Text analytics. It is more cost-effective vs using transactions-based pricing. S0-S4 pricing tiers are now deprecated and you are encouraged to switch to S tier. Guide on how to migrate
