AI Settings

Important

By entering an API key for an AI provider, CAST Imaging users will be able to send snippets of source code to OpenAI / Azure OpenAI / Ollama AI, via the CAST Imaging interface. CAST Imaging does not provide any specific governance of this, therefore you must ensure that your organization’s internal policies around AI authorize this usage.

Overview

CAST Imaging integrates with OpenAI technology (CAST supports OpenAI , Azure OpenAI and local/cloud deployments of Ollama AI ) to provide an automated AI driven explanation of objects materialized during an application analysis. You can find out more details about using AI services in Leverage AI services.

This feature is available only when an API key from a supported provider is configured and when the relevant feature is enabled - see below:

Configuring a provider

Ensure you have generated your API key or have the required configuration data from your chosen provider see below, choose the provider in the drop down and enter the key, then click Update:

The following is required:

Provider	Required
OpenAI	API key Access to `api.openai.com` (port 443)
Azure OpenAI	API Key Endpoint URL: usually this will take the form `https://<app_name>.openai.azure.com` Deployment Name: usually this will take the form `<app_name>` Access to `https://<app_name>.openai.azure.com` (port 443)
Ollama AI	Endpoint URL: usually this will take the form `http://<local_server>:11434`. Model Name: use the following URL to determine your chosen model name: `http://local_server:11434/api/tags` - the minimum model required is llama3.1:70b-instruct-q8_0.

An internet connection is required when inputting the API key for third-party cloud providers.

Enabling AI features

When a valid API key or configuration data is defined, the various AI feature toggles will become available. Use the toggle switches to enable the features you require:

Option	Description
Explain code with AI	Enables right click contextual menu options when consulting results and working at Object level - with options providing explanations directly in the source code:
Assistant chatbot	Enables the chatbot feature located in the lower right corner when consulting results:
Transaction summary with AI	Allows users to generate an AI driven explanation of a given transaction, displayed in a Post-It.

Assistant Chatbot is not currently available when using an Ollama AI API key.

Ensure your source code is accessible

The AI-driven feature are all based on the source code of objects in your application, therefore, CAST Imaging must be able to display source code.

For applications that have been fully analyzed with CAST Imaging, source code will be available by default in the right panel. You do not need to do anything else.
For applications whose results have been imported into CAST Imaging (i.e. the application has not been fully analyzed), you will need to ensure that a datasource is configured. See Managing data source configuration
