Agents can build a whole app's UX now. What if stakeholders could review all the UX changes at once? To go from a V1 to a great app, you need to iterate until it's amazing. Use Decode, work together, and get there the fastest.

Take your LangChain agent public or share it with just those people who need it most with Blocks.ai. No replatforming, no messy middleware, no extra cost to you. How Blocks and #LangChain work together: bit.ly/4hNWzdY

Building #benchmarking and validation tools requires a clear vision for what you want to measure. Product Leader Cres Hay built a blocks.ai agent validation tool with this idea in mind. She defined the input and output criteria before creating anything. Then she built her agent and set it loose to measure agent effectiveness on Blocks. Learn how she did it, get her advice to new builders, and unpack product management in the #agentic age of #AI with her in our latest Blocks Builders series. bit.ly/4yoDggs

AI uses less electricity to write code than a human at a desk: Human: 3 workdays (24 hrs) @ 135W = 3.24 kWh AI Pod: 10 mins @ 5,000W = 0.92 kWh Even drawing 40× the peak power, the AI finishes so fast it uses 3.5× less total energy, including time it takes to correct AI mistakes

You don't need to switch apps to switch models. Switch to @TaskletAI and you can use them all together
Gemini 4 Argon is live in Tasklet. Google’s new frontier model is built for long, multi-step work across finance, legal, and video. Your agents shouldn’t belong to one model. Select Argon on any agent—your connections, skills, and context stay put.

You could call @THEDEVRELMARKUS one of our "founding fathers" as he's been running developer relations for us since the beginning. He built a Plant Doctor agent from a Hugging Face model that blew up in a matter of days - turns out that green thumbs are contagious! Read the full builder story below.
He needed help with apartment plants, found a fine-tuned #Qwen classifier on Hugging Face, ran it locally, then used a Blocks skills file in Cursor to put the agent on the network. The model stays on his machine, the connect out lives with Blocks.ai We interviewed @THEDEVRELMARKUS to get tips for agent builders out there. Habits worth stealing: 🔍 Look on Hugging Face, GitHub, and Blocks before you burn tokens reinventing an agent that already exists. 👩‍🔬 Test edge cases. A keychain photo of a plant convinced his Plant Doctor agent it was looking at a real one. 🚀 Split workflows. Scrape, summarize, and score as three agents, not one mega-agent. Cheap models for the small jobs; the heavy model only where reasoning matters. 🤖 Host skills as agents, not just files. Update once, and everyone calling it gets the new version. The catch: the same skills file does not behave the same on Opus, Fable, and Astra, so eval across models. Read more: bit.ly/4AVTK20
