New features

  • Added ChatDatabricks(), for chatting with Databrick's foundation models. (#82)
  • .stream() and .stream_async() gain a content argument. Set this to "all" to include ContentToolResult/ContentToolRequest objects in the stream. (#75)
  • ContentToolResult/ContentToolRequest are now exported to chatlas namespace. (#75)
  • ContentToolResult/ContentToolRequest gain a .tagify() method so they render sensibly in a Shiny app. (#75)
  • A tool can now return a ContentToolResult. This is useful for:
    • Specifying the format used for sending the tool result to the chat model (model_format). (#87)
    • Custom rendering of the tool result (by overriding relevant methods in a subclass). (#75)
  • Chat gains a new .current_display property. When a .chat() or .stream() is currently active, this property returns an object with a .echo() method (to echo new content to the display). This is primarily useful for displaying custom content during a tool call. (#79)

Improvements

  • When a tool call ends in failure, a warning is now raised and the stacktrace is printed. (#79)
  • Several improvements to ChatSnowflake():
    • .extract_data() is now supported.
    • async methods are now supported. (#81)
    • Fixed an issue with more than one session being active at once. (#83)
  • ChatAnthropic() no longer chokes after receiving an output that consists only of whitespace. (#86)
  • orjson is now used for JSON loading and dumping. (#87)

Changes

  • The echo argument of the .chat() method defaults to a new value of "output". As a result, tool requests and results are now echoed by default. To revert to the previous behavior, set echo="text". (#78)
  • Tool results are now dumped to JSON by default before being sent to the model. To revert to the previous behavior, have the tool return a ContentToolResult with model_format="str". (#87)

Breaking changes

  • The .export() method's include argument has been renamed to content (to match .stream()). (#75)
