Happy birthday MCP! 🥳 The world's fastest growing protocol was released on 26th November 2024 and has captivated developers and users alike. I am certain that everyone reading this newsletter has used MCP in one way or another, and will be happy to hear that there is plenty of work going on to keep improving and evolving the protocol. In the newsletter this week we have stories on prompt caching, JSON outputs, product evals, and the evolution of LLM extensions that has brought us to the state...

There has been a flurry of new frontier models dropping over the last week that you can already use in your applications. Gemini 3 was released today, and Grok 4.1 and GPT-5.1 both arrived last week. This week we're also learning a lot of lessons from how coding agents are built, including building a coding agent in Langflow if you want hands-on experience with your own. There's also much debate over the efficiency of MCP and whether other tools fit the job better. Phil NashDeveloper...

The topic of security, specifically around prompt injection, is often raised and then dropped with a bit of a shrug as the path to a solution isn't very clear. Thankfully there are people out there thinking hard about it. In AI++ today, there are articles from Meta and Perplexity on this, with ways to mitigate the issue that we should all read and learn from. We've also got news of some great AI events coming up, including the online OpenRAG Summit, along with news of introspective AI models,...

If you like building agents that get work done, you're in for a treat in this newsletter. CUGA is a new agent framework that is topping benchmarks and using all sorts of cunning under the hood to help you build better agents that can execute complex tasks. There is also news on model releases, code execution sandboxes, and the latest podcast episode from The Flow, all on OAuth and MCP.

I normally like to open the newsletter with general news in the world of AI, but I've been heads-down with the rest of the Langflow team working on the newly released Langflow version 1.6. With features like OAuth for MCP, a Docling powered file component, and compatibility with the OpenAI API, it's been worth it. What else has been going on then? OpenAI just hosted their DevDay event with a pile of new releases, while Anthropic had people queue for 2 hours for free hats. Everyone else seems...

Over the last weekend the Langflow team was out at the CascadiaJS conference and Cascadia AI Hackathon. It was inspiring to meet so many developers, work with them on their AI hacks, and see fewer demo hiccups than a Meta product launch. The winning team built a full music sequencer, MIDI keyboard and visualizer that generated beats that could then be edited by hand or further with AI. Congratulations to the winning teams and to everyone who built something and learned something new over the...

Who is naming these model releases? Gemini’s new image editing model is called Nano Banana (and they dropped a great tutorial on how to use it as a developer). Meanwhile, Microsoft AI launched two models in the new MAI series, presumably pronounced “my” because they’re not OpenAI models. At least OpenAI, the creators of gpt-4o-mini and o4-mini, were a bit more sensible with their recent release of gpt-realtime along with the generally available Realtime API. And that’s only some of the newly...

Privacy has been a hot topic for consumer AI applications this month. Users have been finding out that chats with OpenAI, Grok, and MetaAI that they shared, were being indexed by Google and showing up in search results. Sharing a chat with your friend doesn't mean you want to share it with every search engine out there, so make sure your users know what they're doing and don't forget your robots.txt. Multi-agent systems are the theme for this newsletter, with tutorials on how to build them...

OpenAI dominated the AI headlines last week with the release of new open weights models (their first open release since GPT-2) and GPT-5. There’s been some user backlash against GPT-5 replacing all the models in ChatGPT, but as developers we can still pick the GPT we want to use. Not wanting to feel left out, Anthropic released Claude Opus 4.1 and the Qwen team impressed with Qwen-Image. This week in AI++ we have some great open-source examples of agents, we dive into UX and accessibility for...
