Read units per month per project

Starter planStandard planEnterprise plan
1,000,000UnlimitedUnlimited
Read units measure the compute, I/O, and network resources used by fetch, query, and list requests to serverless indexes. When you reach the monthly read unit limit for a project, fetch, query, and list requests to serverless indexes in the project will fail and return a 429 - TOO_MANY_REQUESTS status with the following error: 
Request failed. You've reached your read unit limit for the current month limit. 
To continue reading data, upgrade your plan.
To continue reading from serverless indexes in the project, upgrade your plan. To check how close you are to the monthly read unit limit for a project, do the following:
  1. Open the Pinecone console.
  2. Select the project.
  3. Select any index in the project.
  4. Look under Starter Usage.

Serverless indexes per project

Starter planStandard planEnterprise plan

When you reach this quota for a project, trying to create serverless indexes in the project will fail and return a 403 - QUOTA_EXCEEDED status with the following error: 
Request failed. You've reached the max serverless indexes allowed in project <project>. 
Use namespaces to partition your data into logical groups, or upgrade your plan to add more serverless indexes.
To stay under this quota, consider using namespaces instead of creating multiple indexes. Namespaces let you partition your data into logical groups within a single index. This approach not only helps you stay within index limits, but can also improve query performance and lower costs by limiting searches to relevant data subsets. To increase this quota, upgrade your plan.

​
Serverless index storage per project

The query result size is affected by the dimension of the dense vectors and whether or not dense vector values and metadata are included in the result.
If a query fails due to exceeding the 4MB result size limit, choose a lower top_k value, or use include_metadata=False or include_values=False to exclude metadata or values from the result.
