Last Tuesday (9th June 2026), Anthropic released what it described as a safer version of Mythos, its very powerful AI model. The new version was called Fable 5.
There have been a lot of opinions about it online, so I wanted to test it properly myself.
I gave it a big job.
I asked it to help create a new CRM to replace my ageing one, but not just another standard CRM. I wanted AI built into the centre of it, not bolted on afterwards like most large CRMs seem to do.
The starting point was simple enough, projects and tasks.
Also, my current CRM has a built in email client, so the new one needed that too. But this time, I wanted the email side to be semi-controlled by AI, so I only see the emails that actually matter.
Then I pushed it further.
I wanted the AI agents to work more like staff members.
No assigning every tiny task manually. If an agent can do something, it should just get on with it.
If a task is too big, it should be split into smaller subtasks and complete the parts it can.
The goal was simple. I wanted to start work in the morning and find that a large percentage of my tasks had already been done.
On top of that, I wanted each member of staff to have their own AI assistant, helping them with their day-to-day work.
A big ask!
But I did not stop there.
I also asked it to create different versions of the CRM depending on the user’s role, for example, sales, admin, support, or other specialist roles. Because different roles use CRM’s differently.
Then I added one more thing.
I wanted the CRM to connect to my OpenClaw and Hermes PCs, so tasks could also be sent to local computers to run there.
If you have used OpenClaw or Hermes, you will know that managing tasks across them can get messy quite quickly. I wanted the CRM to become the control centre.
So I wrote the whole thing up in a markdown file and gave it to Fable 5.
And somehow, it only went and built it.
Not just a rough idea. A working version.
The agents can take action, work through tasks, improve workflows, and help like a real AI colleague rather than just a chatbot in the corner.
That is the bit that really stood out to me.
This is not just AI answering questions. This is AI becoming part of the working day.
I started writing this post on the 11th June after I had a bit time playing with Fable 5 and my new CRM. Life got in the way again, as it seems too, so decided to finish it off the next day. Little did I know what was going to happen!
On Friday, 12th June, Fable 5 had been pulled and was no longer available. The powers that be decided it was just too powerful for non-Americans and told Anthropic to restrict the model. That is not easy to do, so they had to remove it from everyone.
Hopefully, it comes back soon, because what I saw was a real glimpse of where business software is heading.
I was originally going to say, “Copy the idea above, paste it into Claude and let Fable 5 build the CRM for you too”
That is not possible right now.
But the CRM itself is still here.
So, if you would like to try it and see it in action, comment down below and I will send you a login link so you too can see it in action.
No charge. No sales pitch. Just a chance to see what an AI-first CRM could look like.
