The productivity boost with Muggle Works harness is real. Here is Muggle AI’s Github contribution grapg since 2025: 6 months into 2026 (Muggle Works launched in March), we have already surpassed total contributions in 2025 by 50%. Expect to deliver 3x in 2026 more than 2025. What is your produtivity boost with AI?

Just curious, anyone running fable 5 with loop and not broke?

We are most likely going wait a bit before trying out Fable/Mythos. Not until we can justify the cost of it for our case. I feel a lot of the production use cases probably do not need the extra intelligence either. What do you think? leave a comment below

"What type of error case Muggle Test can catch?" Answer: Not only UI bug, but also broken E2E experience. Here is an example from a real PR: "a broken "create secret" api detected" Start your free trial on muggletest.com

AI subscriptions are dead Claude Fable 5 will only be on the Anthropic subscription until June 22nd. After that, you will need to pay for usage per token This will be the start of a much larger trend Frontier models will no longer be included in subs You’ll pay a fee and it will only get you access to older, much cheaper models If you want access to that dank AI sour diesel, you’re going to need to pay for every token you use. No more subsidies And it make sense. The subsidies were just a Ponzi scheme For those that don’t know, when you pay $200 a month for an AI sub, you get thousands of dollars of tokens These AI companies actively lose tremendous amounts of money because of these subscriptions. GDPs of most countries every year are lost on your $200 Claude Max sub The investor money is running dry. IPOs are coming because of this. And with IPOs need to come profitability The golden age of paying $200 a month and being able to code on 40 Claude Code instances and getting a usage reset every 5 minutes are about to die The party couldn’t continue ever. You can’t just leverage the entire global economy for years and expect nothing to break. Now it’s time to pay up Means a few things: 1. Time to be responsible when it comes to which models you use. You don’t need Fable 5 for GPT 5.5 Xhigh for everything. Build the skill of knowing when to use cheap models 2. Local LLMS/hardware will come even more in demand. I’m currently running GLM on my Mac Studio. It’s great. Is it Fable? No. But it gets the job done for free on simple tasks. Learn about local LLMs 3. This is the beginning of the wealth gap expansion. Those that can afford to spend $10,000 a month on Fable 5 will build incredible products that eat up more and more of the economy. Those that can’t afford Fable 5 will have an insane disadvantage 4. The government will need to step in eventually. There will be too much civil unrest. I hope the answer isn’t free money. That won’t do anything. I hope the answer is education/access to AI resources for ALL. Universal Basic Opportunity 5. You need to seriously reconsider where your money goes every month. If you are complaining about AI prices and in the back of your mind you know your skill set is becoming quickly irrelevant, all while spending money every month on Netflix, Xbox Live, Paramount , drugs, DoorDash, Uber, and other things that bring nothing positive to your life, you are simply doing it wrong. AI is an investment in yourself. It’s an investment in your relevance to the global economy. You need to make sure you make that investment The pieces on the board are quickly moving around. The rules are changing. The battlefield is shifting. If you’re not strategizing accordingly, you’re cooked.

Fable 5 is the biggest step up I’ve felt in our models since Opus 4.5 back in November. After 4.5 came out I uninstalled my IDE when I realized that I’d been doing 100% of my coding in a terminal for a few weeks. With Fable, it’s felt like Claude has stepped up from being a coding agent to a thought and design partner in building the product. Fable has judgement, taste, and dimensionality in a way that previous models didn’t, leading me to trust it more with the most complex work. I think the first time I had this realization was when I asked Fable to debug something. It is the first model I have used that was so methodical and precise, taking measurements and adding logs then verifying that it truly fixed the issue before declaring victory. There’s nothing in claude code’s prompting telling the model to do that, it’s just part of its personality. It really has this “big model smell” that I haven’t felt before.

LOL i think AI is oversold, far from replacing human IMO AI gen code, human keep the gate. I thought it is a common practice to have code review dont we? Shit code has not way making to prod if not for the shitty gate keeper
Replying to @Muggle_AI @shub0414
A slot machine is not a process/culture problem, AI was sold was a replacement to humans that works faster, changing the narrative and blaming the user for a bad tool is a stupid way to approach it.

I would expect the over selling will cool down a bit after the ipos

same. for me the missing piece is less “more commands” and more state awareness: what changed, what failed, what needs a human click, and what should not be touched.

We sre listening, any specific edge case you have in mind?
Replying to @Muggle_AI
This gets more convincing once it handles messy edge cases beyond the launch video.
