Meta’s AI Mission took off last week with the launch of Llama 4.0.
Llama stands for “Large Language Model Meta AI.”
This is a serious upgrade in the world of artificial intelligence.
Hello and welcome back to the AI Six podcast, where I’m helping you embrace AI in just six minutes a day with explainers, tool recommendations, breaking news, and breaking down the AI stories.
Meta has released two main models under the Llama 4 name: they’re called Scout and Maverick. They claim these models are more powerful, more flexible, and smarter than anything Meta has released before.
They can understand not just text, but also images, videos and sounds. That means they’re what’s known as “multimodal”, in that they are able to take in different types of information, just like we humans do.
And in a move that’s helping Meta stand out from the LLM crowd, Meta has made these models open source, meaning anyone can access and build on them. That’s a big shift away from the closed-door approach of other tech giants.Speaking to followers on his Instagram account Zuck said: “Our goal is to build the world’s leading AI, open source it, and make it universally accessible so that everyone in the world benefits.”
What Can Llama 4 Actually Do?
Here are four key things you need to know:
1. It understands more than just words.
Llama 4 can take in videos, pictures, audio clips, and text. That means it can answer questions about a photo, summarise a podcast, or even explain what’s happening in a video.
This could be a game-changer for education, creativity, and customer service.
2. It remembers a lot more.
One of the new models – Llama 4 Scout – has a much bigger “memory” than earlier models. In simple terms, it can hold more information in its head at once – up to 10 million words. That’s like reading five novels at once and still remembering what’s going on.
3. It’s more efficient.
Llama 4 is built with a new design that only “switches on” the parts it needs. That makes it faster and less power-hungry. So it’s better for the planet and cheaper to run.
4. It’s already in your apps.
Meta has quietly rolled out Meta AI, powered by Llama 4, across WhatsApp, Messenger and Instagram. You can now ask it questions, get summaries, and more, right inside your chat.
Try asking Meta AI for recipe ideas, help with homework, or a quick explanation of something complex. You might be surprised at how natural it feels.
Llama 4.o being open-source is big news, but why?
When something is open source, it means the code and model behind it are freely available for anyone to use, study, or build upon.
That’s quite rare in the world of AI, especially when we’re talking about models as powerful as Llama 4.
Here’s why it matters:
1. More access = more innovation
When developers, researchers, and even startups can access the model without needing to pay massive licence fees, you open the door for new ideas, faster progress, and tools that might never have been built otherwise.
Think of it like this: Meta has built the Lego blocks, and now anyone can come and build their own creation with them.
2. It’s not just for the big players
AI development has often been dominated by huge companies like OpenAI, Google, and Microsoft, who mostly keep their models behind closed doors or locked behind subscriptions.
By going open source, Meta is saying: Let’s not keep this to ourselves.
That means universities, charities, public services, and small businesses can now experiment with cutting-edge AI too, not just Silicon Valley giants.
3. It encourages trust and transparency
When the model is open, people can actually see how it works, test its limits, and understand what it’s doing with their data.
That makes it more transparent and potentially safer. You can spot biases, test for misinformation risks, and hold the model to account.
It’s a step away from the black box approach of “just trust us”.
4. Global collaboration
Open-source models spark community involvement. Developers all over the world can help improve it, fix bugs, and add features, which means it evolves faster and better.
It’s like Wikipedia vs a private textbook: more eyes, more input, more value for everyone.
Bottom line?
Meta’s decision to open-source Llama 4 is a bold move that democratises AI. It puts powerful tools in more people’s hands — which could lead to breakthroughs in healthcare, education, the arts, climate solutions, and more.
It’s not just a tech launch. It’s an invitation.
So my final thoughts:
- AI just got a lot smarter and a lot more accessible.
- Llama 4 is built to help, not replace, whether that’s answering questions, helping you be more creative, or saving you time.
- Meta’s move to open-source this tech could spark huge innovation around the world.
