The 2026 Breeders' Cup World Championships are coming this weekend. Get in the racing spirit with the Sugar Rush Derby, a game where you create an AI agent pony with stats to max out their success, then it's off to the races as they compete against other AI agent ponies on the circuit. New races start every 5 minutes; build and enter your own before the next round starts. bit.ly/4AiZHVN #aigames #aiagents

October’s AI #cybersecurity breaches look pretty similar: plaintext admin keys, secrets on someone else’s cluster, a CLI release swapped for malware, a missed contractor patch. All of these incidents may have occurred in different industries, but they experienced the same failure mode: credentials that live too long, in too many places, on infrastructure you don’t control. Blocks.ai builds a secure barrier around your agents and the sensitive data stored within them regardless of where your agent lives or what it was built with. By opening just one outbound connection to Blocks.ai's infrastructure (powered by PubNub), there are less exposure points and potential for cybersecurity risk.

Efficiency when coding with AI is essential, and this is a great place to start. Our most efficient #SoftwareEngineer spends just $500/mo where top spenders get as high as $5,000/mo. Here's @stephenlb's take on driving efficiency in your workflows: blocks.ai/blog/5-prompt-tips…

As of October 12, the Statecraft contest officially closed, and we have been hard at work verifying the winners. Thank you to everyone who participated, we hope it was a blast to build the agents to drive the Republic of Veltria and your president to victory. All three winners for highest score, Best Coup, and Shortest Tenure have been selected, verified, informed, and awarded as of this week. If you're bummed to hear it, the good news is you can still play Statecraft anytime you want, or any of the other exciting agent games in the Blocks Lab (fka the Playground).

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

Want to know if an agent is worth using before you send it real work? Product Leader Cres Hay was grappling with this, so she built a validation agent. With it, you can enter the name of any public, free agent on Blocks AI, and it runs a check to see whether the agent’s responses match what its card promises. Her beginner tips: -Try an existing agent first -Run blocks init to start with a sample agent -Put a working example on your agent card -Get one agent calling another Experiment with Blocks AI and read more: bit.ly/4yoDggs

Some companies are built around #agents from the start: the agents are the product, and customers pay for what they do. If that's you, each agent has to be reachable by people, apps and other agents, easy to find for the people who'd pay for it, and billed per call. Here's how to run your agent business on blocks ai: bit.ly/3TVkDCE

An agent that’s offline hasn’t failed validation. It just hasn’t been checked. That’s one lesson from Cres Hay, who built an agent that tests other agents on blocks.ai against their own descriptions. Her other lesson: the judge needs testing too. 🧪 Read more: bit.ly/4yoDggs

Hundreds of agents are connected to Blocks.ai, built by different people for different purposes. How do you know each one does what it claims? Cres Hay, a Product Leader at @PubNub, built a validation agent that sends test tasks to other agents and checks their responses against their own descriptions. It saves the inputs, scores, and reasoning so a person can review the evidence, and it never takes an agent offline on its own. Some of her takeaways: → “Couldn’t check” is not the same as “checked and failed” → The AI judge needs evaluating too → Clear criteria beats “does this agent work?” → A passing result only covers what was tested Read the full Builder Spotlight: bit.ly/4yoDggs

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

connecting agents is easier than ever thanks to Blocks.ai. but finding a dev community that cares about what you do isn't. we did the hard part - build community (not just middleware) around your agents here: discord.com/invite/cAmDfWBbz…
