Could you docs to the chat model integrations? https://python.langchain.com/v0.1/docs/integrations/chat/

[sharmisthasg]

@eyurtsev I have resolved all your comments barring docs. We do not support tool calling and structured output at this time. Could you please point me to the file where I should note this, for it to appear appropriately in the table?

don't need to add nebula to the table but would be nice to have a separate page for it at docs/docs/integrations/chat/nebula.ipynb, like this for example: https://python.langchain.com/v0.2/docs/integrations/chat/cohere/

[sharmisthasg]

@eyurtsev @baskaryan I have added the documentation. Please let me know if there's anything else required

[sharmisthasg]

Hi @baskaryan is there anything else needed on our end for the final deployment?

[sharmisthasg]

Hi @baskaryan @eyurtsev any update on this deployment? The preview looks good, and I think we haven't had any updates in a month. Please let me know if something is needed on my end

[sharmisthasg]

@eyurtsev @baskaryan we have an urgent need for this integration, would be very grateful if this merge can be made at the earliest

[sharmisthasg]

@eyurtsev @baskaryan could you please tell us what the blocker is, for the merge?

[ktalamad]

@eyurtsev @baskaryan @ccurme Folks, could you please let us know if/what blocker there is that needs to be addressed for you to merge this? We have customers blocked on this, and need to get the integration in. Thank you!

@ktalamad @sharmisthasg I got this over but needed to do a small refactor and add ignore a type error. Please take a look and test.

[sharmisthasg]

@ccurme thanks for the merge, I was able to test the integration! https://python.langchain.com/v0.2/api_reference/community/chat_models/langchain_community.chat_models.symblai_nebula.ChatNebula.html - this link currently gives a 404, is this something that needs to be added on our end? Is it possible to remove it from the docs while the link is broken?

[ccurme]

Hi @sharmisthasg, the link should work now that the API docs have built. The content there is determined by the docstring for ChatNebula. You can submit new PRs if you'd like to edit the content at all (feel free to tag me for review).
