Example Code

import { ChatXAI } from "npm:@langchain/xai";

const makeModel: BaseLanguageModel = (baseModel: BaseLanguageModel) => {
   return baseModel
}

makeModel(ChatXAI({}));

Description

I'm having a lot of trouble to get multiple providers to work together with the same versions of langchain core and lanchain community.

Often, I get the problem:

Type 'ChatFireworks' does not satisfy the constraint 'BaseLanguageModel<any, BaseLanguageModelCallOptions>'.
  Types of property 'caller' are incompatible.
    Type 'import("file:///Users/andy/Development/myproject/$node_modules/.deno/@[email protected]_1/$node_modules/@langchain/core/dist/utils/async_caller").AsyncCaller' is not assignable to type 'import("file:///Users/andy/Development/myproject/$node_modules/.deno/@[email protected]/$node_modules/@langchain/core/dist/utils/async_caller").AsyncCaller'.
      Property 'maxConcurrency' is protected but type 'AsyncCaller' is not a class derived from 'AsyncCaller'.deno-ts(2344)

Right now, by using the latest langchain/community (0.3.30) and latest langchain/core (0.3.40) I'm able to get OpenAI, Bedrock, Anthropic, Gemini & VertexAI working.

However, XAI & Groq both have this issue (e.g. this is for groq):

Type 'ChatXAI' does not satisfy the constraint 'BaseLanguageModel<any, BaseLanguageModelCallOptions>'.
  Types of property 'caller' are incompatible.
    Type 'import("file:///Users/andy/Development/myproject/$node_modules/.deno/@[email protected]_1/$node_modules/@langchain/core/dist/utils/async_caller").AsyncCaller' is not assignable to type 'import("file:///Users/andy/Development/myproject/$node_modules/.deno/@[email protected]/$node_modules/@langchain/core/dist/utils/async_caller").AsyncCaller'.
      Property 'maxConcurrency' is protected but type 'AsyncCaller' is not a class derived from 'AsyncCaller'.

Normally I think the answer is in package.json you can force specific versions. But I'm using deno which doesn't seem to have this feature.

Frustratingly it's only these two providers which have this problem, is there a workaround here?

Maybe I should request that these get updated to latest langchain core?

A similar issue has been reported regarding type mismatch errors in Deno when using different versions of @langchain/core with various providers like ChatOpenAI and ChatGroq. The suggested solution is to ensure that all related packages are using the same version of @langchain/core. You can update your import_map.json to ensure that both langchain/ and @langchain/core/ are using the same version, such as 0.2.29. This should help maintain consistency across different chat models and avoid type mismatches ^[1].

In your case, you might want to ensure that all your imports, especially for @langchain/xai and @langchain/groq, are aligned with the same version of @langchain/core that you are using for other providers. This might involve checking if these packages have specific dependencies on a different version of @langchain/core and adjusting them accordingly.

In my case, I'm defining the inputs in my deno.jsonc file (included). And it should be using this when importing in my code. It should be using whatever version is defined in my deno.jsonc file so there shouldn't be a version mismatch at all.
