Nodes

Find these under OpenAI API. Connect Client → Chat Completion; chain option nodes into its Options input as needed.

| Display name | Node ID | Purpose | | --- | --- | --- | | OpenAI API - Client | Comfpod_OpenAPI_Client | Set the API base URL, key, timeout, and retries | | OpenAI API - Chat Completion | Comfpod_OpenAPI_ChatCompletion | Send text, images, or both; return a response and conversation history | | OpenAI API - Batched Chat Completion | Comfpod_OpenAPI_BatchedChatCompletion | Run independent completions sequentially and return responses in input order | | OpenAI API - Seed | Comfpod_OpenAPI_Seed | Set the request seed | | OpenAI API - Temperature | Comfpod_OpenAPI_Temperature | Control sampling randomness | | OpenAI API - Max Tokens | Comfpod_OpenAPI_MaxTokens | Limit response tokens | | OpenAI API - Top P | Comfpod_OpenAPI_TopP | Set nucleus sampling probability | | OpenAI API - Frequency Penalty | Comfpod_OpenAPI_FrequencyPenalty | Penalize tokens based on how often they appear | | OpenAI API - Presence Penalty | Comfpod_OpenAPI_PresencePenalty | Penalize tokens that have already appeared | | OpenAI API - Developer Role | Comfpod_OpenAPI_DeveloperRole | Choose the instruction message role | | OpenAI API - Extra Body | Comfpod_OpenAPI_ExtraBody | Add custom request body parameters | | OpenAI API - Multiline String to List | Comfpod_OpenAPI_MultilineStringToList | Split multiline text into a STRING execution list | | OpenAI API - Image Batch List | Comfpod_OpenAPI_ImageBatchList | Collect images and batches into one list while preserving each batch | | OpenAI API - Image Batch to List | Comfpod_OpenAPI_ImageBatchToList | Create one group per source image, optionally prepend or append common images without resizing, and output the group count | | OpenAI API - Repeat String to List | Comfpod_OpenAPI_RepeatStringToList | Repeat a complete prompt into a STRING execution list; connect the image group count to match prompt counts | | OpenAI API - Image Batch List to Images | Comfpod_OpenAPI_ImageBatchListToImages | Expose all image groups or one selected invocation as an IMAGE execution list for Preview Image, preserving image order and original sizes | | OpenAI API - CLIP Text Encode List | Comfpod_OpenAPI_CLIPTextEncodeList | Encode each prompt separately with one shared CLIP model and return complete CONDITIONING objects as an execution list in prompt order |

Internal node IDs use the Comfpod_OpenAPI_ prefix to avoid registration collisions with the upstream OpenAI API nodes. Saved workflows using this fork's old OAIAPI_* node IDs need migration: update those nodes' type values (or class_type values in API-format prompts) to Comfpod_OpenAPI_*, keeping the suffix unchanged. Only migrate nodes intended to use this fork; upstream nodes keep their existing IDs. Old-ID aliases are not registered.

Image Batch List to Images: Connect Image Batches from Image Batch List or Image Batch to List, then connect Images to Preview Image. Invocation Index is -1 for all invocations in order, 0 for the first, 1 for the second, and so on. Each image is a separate execution-list entry, preserving its original size; common images appear again for each invocation that includes them.

CLIP Text Encode List: Connect a single CLIP model and a STRING execution list (such as Responses from Batched Chat Completion). Each prompt produces its own complete conditioning, including scheduled entries, in the original prompt order.
