Python and Node SDK v2.0.0

Released version 2.0.0 of the Python and Node SDKs

The 2.0.0 release includes new functionality for the Writer SDKs for Python and Node:

  • Model delegation tool: A prebuilt, remotely executed tool that lets you delegate domain-specific requests to the appropriate Palymra model. For example, if your application has finance questions, you can use the tool to allow Palmyra X 004 to delegate these questions to Palmyra Financial. Read more in our model delegation guide.
  • Retrieve application details: Retrieve details for all of your no-code applications. Programmatically retrieve application inputs rather than relying on the AI Studio UI. This pairs well with our guide on using no-code applications as tools.
  • Async jobs: Trigger no-code application content generation asynchronously and retrieve or retry the job at a later time. This is great for long-running no-code applications, such as research assistant applications. To learn more, check out the guide on async jobs.
  • Associate Knowledge Graphs with chat applications: Retrieve or update which Knowledge Graphs are associated with no-code chat applications.
The 2.0.0 release includes some breaking changes to the underlying models used in chat completion. This won’t affect you if you are only using chat completion via the Writer.chat.chat method, but it will if you are importing specific types directly. See below for more details about changes in each SDK.

See the SDK repositories for the full changelogs:

Additionally:

  • The types.chat_completion_chunk.Message type has been moved to its own model: types.chat_completion_message.

  • types.chat.ChoiceLogprobsContent, ChoiceLogprobsRefusal, ChoiceLogprobsContentTopLogprob, and ChoiceLogprobsRefusalTopLogprob have all been deduplicated and replaced by a shared model types.shared.logprobs_token.LogprobsToken.
