Each model provider has a different format

Hi team,

I am using the GET /workflows API to retrive information of all workflows.
I have observed that the AI Language Model node differ greatly in their structure.
For example, Anthropic Chat Model has following structure. Model name is available in parameters.model.value

{
          "parameters": {
            "model": {
              "__rl": true,
              "mode": "list",
              "value": "claude-sonnet-4-20250514",
              "cachedResultName": "Claude 4 Sonnet"
            },
            "options": {}
          },
          "type": "@n8n/n8n-nodes-langchain.lmChatAnthropic",
          "typeVersion": 1.3,
          "position": [
            400,
            220
          ],
          "id": "u-u-i-d",
          "name": "Anthropic Chat Model"
        }

Google Vertex Chat Model has following structure with model name in parameters.modelName

{
          "parameters": {
            "projectId": {
              "__rl": true,
              "value": "p-r-o-j-e-c-t--i-d",
              "mode": "list",
              "cachedResultName": "p-r-o-j-e-c-t--i-d"
            },
            "modelName": "gemini-2.0-flash",
            "options": {}
          },
          "type": "@n8n/n8n-nodes-langchain.lmChatGoogleVertex",
          "typeVersion": 1,
          "position": [
            940,
            1080
          ],
          "id": "u-u-i-d",
          "name": "Google Vertex Chat Model",
        },

AWS Bedrock Chat Model has the following structure with model name in parameters.model

{
          "parameters": {
            "model": "amazon.nova-lite-v1:0",
            "options": {}
          },
          "type": "@n8n/n8n-nodes-langchain.lmChatAwsBedrock",
          "typeVersion": 1,
          "position": [
            1500,
            1180
          ],
          "id": "19454728-dc00-4fa7-99dd-d04a33b23c07",
          "name": "AWS Bedrock Chat Model",
          "credentials": {
            "aws": {
              "id": "e4S89Oh7WGho1dUp",
              "name": "AWS account"
            }
          }
        }

Is there a documentation where I can find the response format for Chat Model node?
Also, are there any new providers being added? Any roadmap sort of?
