Think it through
Reasoning models
An owner is weighing up two ways to handle enquiries.
Work through the options, constraints and trade-offs. Give the owner a clearer decision to make.
The AI we use
The right AI.
For the job at hand.
Your agent has work to do. We choose the model around that work, then connect it to your business through ISA's own frameworks, refined on real client work.

Start with the work.
A model can do several of these jobs. The examples below show how we choose.
Find the words
Language models
A quote needs a clear, polite follow-up.
Turn the right business details into a useful draft, summary or reply. Match the tone and leave the important sends for approval.
Read what arrived
Models that read text and images
An invoice arrives as a scanned PDF.
Read the page and pull out the details for a person to check. These are often called multimodal models because they work with more than words alone.
Move the work along
An agent connected to tools
An approved enquiry needs to become a CRM record.
Use the model inside an agent that can take agreed steps in your tools. ISA sets up the workflow, access and approval rules around it.
Our working toolkit
Leading labs.
Open source, too.
We build and test with Anthropic's Claude, OpenAI, Google's Gemini, xAI's Grok, and open-source models and agents. Each job goes to whichever model does it best.
Open models give us another way to build. Ask Marcus on this site runs on OpenAI's open-weight gpt-oss model. Hermes is an open-source agent that can work with different models and tools.
Meet Ask MarcusThe model, tools and access for your business are agreed around your job. You stay in charge of the decisions and approval rules.
We keep up.
You don't have to.
We review this page monthly alongside the research for the Care AI report: what has changed, what is useful and what fits the work. The report is included in Essential and Growth Care; implemented monthly AI upgrades are included in Growth.
