+# Hackathon Outcome: Generalising the chat-gpt-plugin
+
+A requirement has been raised by customers of Gerrit that they would love to have the functionality shown
+by the current [chatgpt-code-review-gerrit-plugin](https://github.com/amarula/chatgpt-code-review-gerrit-plugin/), 
+without the need of sending important Intellectual Property, to a public service.
+
+As such during the hackathon it was accepted that it would be good to take the current chat-gpt gerrit plugin
+and to create a more generic `ai-code-review` plugin that could be used with on-premise, private hosted or public AI services.
+
+The starting point of this was to create a fork of the current chatgpt plugin, in the gerritcodereview section
+under [plugins/ai-code-review](https://gerrit-review.googlesource.com/admin/repos/plugins/ai-code-review).  
+
+All classes that are not chatGPT specific, which is most of them, including the configuration
+options where to be generally renamed.
+
+e.g. gptModel -> aiModel
+     gptToken -> aiToken
+
+A great benefit was that ollama has now extended their API with the OpenAPI specification so that they present
+an endpoint which allows compatiblity with chatGPT OpenAPI specification for requests and responses.
+
+## AIType Support
+A new concept has been added to the plugin to allow the specification of different AITypes.
+
+As such a new configuration option called `aiType` can be specified as follows:
+ - CHATGPT (default if not specified)
+ - OLLAMA
+ - GENERIC 
+
+### OLLAMA
+The ollama AI service, must be run against a model which supports the "tools" and "functions" extensions so that the 
+response object can be easily specified to return in the correct JSON schema by the prompt.  Without this the default
+is to return markdown json, which would require much more processing on the client side.
+So make sure that the OLLAMA model you choose appears in this list: 
+[ollama models (tools-filter)](https://ollama.com/search?c=tools)
+
+### GENERIC 
+The generic ai service ability has been added, to more easily test against a potentially new or not yet supported
+endpoint.  It does so by allowing you to specify the authorization header (key: `aiAuthHeaderName`), along with the 
+different API endpoint URI (key: `aiChatEndpoint`) which can be used for the code review.
+e.g. instead of /v1/chat/completions it might be /api/chat
