2025 will be the year we see the first self-driving startups. Level 0: No AI .People do everything. They come up with ideas, build products, and run operations. Many legacy businesses still work this way. Level 1: People use AI tools ⬅︎ we are here.People might use ChatGPT.

Building on durable objects is so fun. Took me 10 LOC to make our cloudflare agents subclass automatically resume LLM requests that got cancelled because the durable object crashed or got evicted or whatever

Does parallel tool calling not work in the openai responses API when streaming or something? Even when I set parallel_tool_calls: true, I can't get any model to start more than one function tool call per response.

5 y/o had friends over and did a spy meeting. I found this afterwards:. Plan to escape. Shoot the grownups. ❤️

Insane when your AI gets involved without you even planning for it

Massive accomplishment. Congrats @antonosika and team 🫡.
Lovable just raised $200M at a $1.8B valuation led by Accel. This all started unexpectedly with me calling my friend at 6AM to go for a walk. I've never shared this story before: (thread)

Let’s savour this one last time.
Humanity has prevailed (for now!). I'm completely exhausted. I figured, I had 10h of sleep in the last 3 days and I'm barely alive. I'll post more about the contest when I get some rest. (To be clear, those are provisional results, but my lead should be big enough)

Getting to that age where most people I meet don't even know who Guybrush Threepwood is.

Imagine a Silicon Valley startup doing this. No over-strategizing. Just ship. I guess it’s not obvious this is actually a good strategy for Kimi, but it is certainly good for us!.
We've heard your feedback — Kimi K2 is SLOOOOOOOOOOOOW 😭.Especially for agentic apps, output tokens per second really matters. The main issue is the flooding traffic and huge size of the model, we are actively working on inference optimization and BUY MORE MACHINES!. Speed.

Cursor keeps suggesting irrelevant things like "User prefers the padding on the right side of the stream to be p-4 when working in this repo". Making a good memory system for LLMs is hard!.
