So basically Jev from Google?
Today we’re launching the Gemini Decisions API, powered by our new Gemini Decision 1 model in @GoogleAIStudio. Instead of generating text token by token, it’s built for closed-set choices scoring up to 1,000 questions across text, images, audio, video + PDFs in a single pass. A few details: - 3 decision types: yes/no, multiple choice (up to 255 options) + rubric scoring - $0.10 / 1M input tokens with $0 billed for output tokens (~5x cheaper than Flash-Lite) - leads on several benchmark evals with lowest calibration error Google teams are already building with it, below is a look at Stitch Rapid designing a full product flow in seconds (1x speed)

This Chhath Puja, we’re creating a special film from Dukaan celebrating Biharis building India’s future. Bihar has given India incredible entrepreneurs, engineers, technologists, scientists, researchers, creators and changemakers. I want to discover such stories. Tag someone from Bihar who’s doing meaningful work - whether they’re building a company, developing technology, working on breakthrough research, creating jobs or making a difference in their field. They don’t have to be famous. They just have to be doing something worth celebrating. Let’s show India what Bihar is capable of. ❤️

So much potential in the state, still needs to be utilised properly.

HIRING DEVS! I'm hiring agentic developers to work on a special project. The work is incredibly fun, and we are offering fully remote, well paid positions. Extra points if you're in Toronto as well. If you want to come work on the coolest thing of your career with other highly motivated A players, this is your chance! DMs open. I read every single DM!

Is it a new position? Or the same old position?

Anyone who tells you money won’t make you happy is lying to you. My AirPods Pro just broke. A year ago, I’d have stressed for an hour over which replacement I could afford. But this time, I just asked Claude. It found an Apple store 10 minutes away. So I got on my bike, rode straight there, and bought the new AirPods Pro 3 without thinking twice about the $249 price tag. Sure, money won’t make you fulfilled. But it sure as heck will give you the mental space to find fulfilment.

You lived through the scarcity to let abundance make you happy. I wonder if it works if you already have abundance.

working with AI is fundamentally asking someone else to produce the work you want we spend a lot of time communicating context, goals, giving feedback, setting rewards, shaping workflows and SOPs. it’s a managerial experience i’ve always felt a bit sad about that, because it took away the experience and joy of being a pure craftsman that produces great work directly chopin can’t be chopin by hiring a team and telling his employees to compose for him. these masterpieces had to be created by a craftsman directly, and i think many of us humans deep down seek that mastery and joy when the world gets filled with more and more agents and robots, every human’s job becomes an agent manager are we sure that’s what we want?

There will be a lot of new creative and un explored jobs coming up. There used to nothing called a programmers centuries ago.

NEW: Bambu Lab just launched a 3D printer with nine interchangeable tools that can switch between colors, materials, and nozzle sizes mid-print. The H3C is built to make complex objects in one run without constantly stopping to swap filament or hardware. -9 printing tools stay loaded and ready to use -Switches between materials in about 6 seconds -Can combine hard plastic and soft, rubber-like TPU in the same object -Uses different nozzle sizes in one print for both speed and fine detail -Can create a wider range of colors from five base filaments -Optional tools let it cut, draw, and press designs into materials Starts at $2,499.

What a world it would be if we can build custom appliances for cheap and according to needs a well.

Sandboxes have no moat. Just fat margins. We're launching agent37.com to kill those margins. For example, a sandbox with 2 vCPUs and 4 GB RAM when left running for an entire month: Vercel: $249 Cloudflare: $145 Daytona: $121 Agent37: $4.76 There's nothing magical about a sandbox that justifies keeping it expensive forever. Call it a race to the bottom. We'll see you there. If you can find a cheaper sandbox and we'll refund the difference.
Readers added context they thought people might want to know
Vercel and Cloudflare charge for active CPU time (excluding idle/waiting periods common in agent use) and provisioned memory while running, unlike the full-month 100% utilization figures quoted; Daytona bills full reserved resources while started. vercel.com/docs/sandbox/p… developers.cloudflare.com/containers/pla… daytona.io/pricing agent37.com

Unbelievable, Will have to explore. Is it possible for you to breakdown how and why so cheap even compared against the giants? Do you own the compute? Is it subsidised only for now?

Well I might consider it for oled and the weight. It's pretty light. But, let's wait it out till we see M6pros there. plus it's out of my budget 😂😆

RAG is officially cooked. IBM built a retriever that hallucinates 65x less than fine-tuned RAG systems. Right now, every company is using Retrieval-Augmented Generation (RAG) to stop their AI from hallucinating. The idea is to give the AI a private database to read so it doesn't make things up. But there is a massive structural flaw. Standard RAG blindly grabs documents based on vector similarity and forces the AI to read them. If the retriever pulls irrelevant garbage, the AI doesn't stop. It just hallucinates with citations. IBM just dropped a paper that changes the math entirely. They built a new retrieval architecture that hallucinates 65x less than state-of-the-art fine-tuned RAG systems. 65x is the difference between a fun prototype and a production-grade enterprise system. Instead of blindly dumping context into the model and hoping for the best, their system actively filters and validates the retrieved data before the generation step even begins. It cuts out the noise. It forces absolute precision. For businesses, this is the holy grail. Zero hallucinations means zero liability. It means autonomous agents can finally be trusted with sensitive company data without a human babysitting every output.

Well it will take a while for this to be in production so I will use RAG till then .

someone outside our GitHub org deleted one of our private repos. no membership or invite or role. nothing in our org or enterprise audit logs gave them access. just one repo.destroy from the gh CLI. and it's not in deleted repositories, so no restore. @github how is this possible, what sorcery is this?

2026 might be tbe worst year to buy high end flagship smartphones in India. Even the base variant models for new flagship series phones would be touching a lakh, the Pro model touching 1.3 - 1.5L and let's not speculate regarding the Ultra models moving forward. So you were expecting to buy a flagship smartphone be ready to pay 35-50% more for new models, my advise use your old phone if it's working well but If you really need to upgrade look for last year models.

Now it will only continue to rise. No hopes for it to go down.

Yubikey prices after this post 🪜☝🏻
I spent the last 48 hours rotating passwords, adding 2FA everywhere, and spawning agents to audit all my startups' codebases. I tried to brute-force my own code, but, of course, OpenAI and Anthropic models wouldn't let me. I also ordered a YubiKey for myself and to apply to OpenAI's Daybreak program. I called my family and told them to do the same (rotate pwd + add 2FA). Black October was the tip of the iceberg, I think.
