Pinecone has enhanced its Starter (free) plan, crucial for developers building AI applications, by tripling its capacity through a serverless upgrade. This update offers users 2GB of storage capable of handling approximately 300,000 records, along with monthly quotas of 2 million Write Units and 1 million Read Units, which reset each month. Free users can now create up to five indexes with as many as 100 namespaces per index, facilitating experimentation with multi-tenant use cases before scaling to production. The transition to larger plans is streamlined, allowing users to upgrade without creating new indexes or projects, although serverless usage incurs charges post-upgrade. The serverless plan is now available, with easy onboarding through a quickstart guide, and support for migrating existing indexes is forthcoming.
