AI has officially gone mainstream. 📈85% of developers use AI for coding. The data tells the story. The State of Developer Ecosystem 2025 Report is live. 🔗 See what’s shaping the next era of software: https://jb.gg/deveco-2025

Not every developer task requires a general-purpose LLM. We’re betting on specialized focal LLMs – smaller, faster, and focused. Join @jetbrains and @huggingface for a livestream on how focal models like Mellum will shape the industry. 📅 July 29, 6 pm CET 👉 Save your spot: jb.gg/uvl8n5

#PyConUS 2025 was an absolute blast! 🎉 We loved being part of the amazing #Python community, exchanging ideas, and showcasing the latest AI features in PyCharm. 🎥 Catch the video recap and feel the energy! How was your experience? Let us know in the comments! ✨

❓ Why did JetBrains build its own LLM? Because not every model needs to be a generalist. Meet Mellum — a fast, lightweight LLM for code completion 🤝 ▶️ youtu.be/7TqkvVXKxFA 💻 Try it in your JetBrains IDE: jb.gg/eg5f1f 🔬 Explore it on Hugging Face: huggingface.co/JetBrains/Me...

Hard disagree here. There’s a difference and a line between freedom of speech and a masked hate group marching through downtown. KC should not tolerate nor welcome the latter.

Can’t express how happy I am to have Wilbur back to work & on his first flight with me since his cancer diagnosis and lung surgery 💛

C# could never 😇 pythonic, iconic, and ready for #PyConUS 💅🏻

AI ethics requires finding middle ground between competing values. With shifting regulations, companies and users must prioritize transparency and responsibility. As @aiwithmichelle.com notes, in a conversation with @hanneslowette.net: "Don't be evil" remains essential.

It happened: today @lysnikolaou.com merged the PEP 750 t-strings PR for Python 3.14. Kudos to the long list of folks involved: Jim Baker, Guido, Dave Peck, Koudai, Andrea, and Lysandros (and me.) Thanks to Koudai and Misha/Daniil from PyCharm, here's a sneak peak of PyCharm support.

I’ve so much fun working on this collab with @jetbrains.com x @hf.co 🤗 Mellum is now open sourced and available on Hugging Face! More content related to this release coming soon, but for now, check this out: jb.gg/hi_mellum (And an extra special thank you to @witko.bsky.social for the swag 💕🤗)

🤗🤗🤗

JetBrains has been quietly building something special for the open-source LLM community. More details will be posted soon on Hugging Face. Stay tuned! 🧑‍💻

@devoxx.uk 2025 is just three weeks away and I am so looking forward to it!! If you are in or around London, tickets are still available here: www.devoxx.co.uk#tickets 🔥

All JetBrains AI tools – including our improved AI Assistant and new coding agent Junie – are now available within our IDEs under a single subscription and come with a free tier. Read the blog post for more details: 👉 jb.gg/jetbrains-id...

The @devoxx.uk schedule is LIVE! Our team have put together an awesome lineup of speakers & sessions covering Java, AI, Security, Culture & much more. Some of your favourite speakers will be there, along with some exciting new faces. Which sessions are you excited about? devoxx.co.uk/schedule/

🚀 Our AI code completion is getting smarter every day, and we’re bringing you along for the ride! 📈 Higher acceptance rates ❌ Fewer canceled suggestions 🤯 No LLM retraining needed! Curious how we pulled it off? 👀 #JetBrainsAI #LessIsMore jb.gg/kk6nty

It’s been a whirlwind rollercoaster of a few weeks here, after finding out the Very Best Boy™️ Wilbur had lung cancer. 4 days post surgery, seeing this boy up, walking (albeit like a drunk man), and smiling (!!) brings me the greatest joy 🖤

Do you use Kotlin DataFrame or have you used it in the past? The team is looking for feedback and suggestions #kotlin #dataframe github.com/Kotlin/dataf...

To whomever needs to hear this: using AI-powered web search or even the Deep Research tool (and competitors) is not “research”. A scientific and methodical process != “I read a few prompted articles and/or summaries”. Thank you, and good day.

🔥 Get more AI power in JetBrains AI Assistant! AI Assistant now supports the latest models: ⚡ GPT-4.5 (OpenAI) 🧠 Claude 3.7 Sonnet (@anthropic.com) 🚀 Gemini 2.0 Flash (Google DeepMind) Pick the model that fits your coding needs and boost your productivity! jb.gg/oag_b

Wilbur is doing his best to distract me from work this morning 🥺

Every time I think I’ve hit my shocked/horrified limit…. The post moves

I’ll take an easy ‘What Not To Do With AI’ For 100, Alex

Heads up for all the lucky folks who has access to #JetBrains #Junie EAP! Do you wanna know how to optimize using follow-up prompts and new prompts? Here is a tip for you (link in comment) #AI #prompts

After 6+ months in the making and over a year of GPU compute, we're excited to release the "Ultra-Scale Playbook": hf.co/spaces/nanot... A book to learn all about 5D parallelism, ZeRO, CUDA kernels, how/why overlap compute & coms with theory, motivation, interactive plots and 4000+ experiments!
