.@SFMTA_Muni what is up with these new concrete things on Folsom @ 21st? They cause cars to just drive into the bike lane and it’s really dangerous for bicycles. Here is a small sample of people doing it over just a couple minutes. Cc @sfbike
Our 20-month-old has figured out how to consistently open a baby gate. While I appreciate his problem solving skills, I thought we had more time of being able to contain him :|
Our new model Claude 2.1 offers an industry-leading 200K token context window, a 2x decrease in hallucination rates, system prompts, tool use, and updated pricing. Claude 2.1 is available over API in our Console, and is powering our claude.ai chat experience.
Pretty exciting personal news news. Started a new job today at Anthropic! Really pumped about the mission, team, and product!
It’s that time of year when it’s 100% worth it to have a portable AC for 2 nights or so.
Pretty happy how this magical little box came out (for controlling LEDs). Has a built-in wireless DMX receiver, panel mounted power, and stereo input (for sound reactive animations). Powered by a teensy 4.0 (with a beastly 600mhz arm cortex w/ FPU). Not super fun wiring it tho
I probably won’t have anything good to post, but same name on threads threads.net/@mikelewis
Convenient (and probably dangerous) way to roll up tie down and ratchet straps
Ooh are these some Osprey flying over the bay?
Really don’t like SF making national headlines these days :(
Great way to start off a day. Accidentally emailed whole office about a chair 🤦♂️
Neighbor: Are you working on a cool project? Saw you with a dome thing Me: Nope. I have disgusting cats and deep cleaning a disgusting robot

I gave Claude 3 the entire source of a small C GIF decoding library I found on GitHub, and asked it to write me a Python function to generate random GIFs that exercised the parser. Its GIF generator got 92% line coverage in the decoder and found 4 memory safety bugs and one hang.

Fun story from our internal testing on Claude 3 Opus. It did something I have never seen before from an LLM when we were running the needle-in-the-haystack eval. For background, this tests a model’s recall ability by inserting a target sentence (the "needle") into a corpus of…

Today, we're announcing Claude 3, our next generation of AI models. The three state-of-the-art models—Claude 3 Opus, Claude 3 Sonnet, and Claude 3 Haiku—set new industry benchmarks across reasoning, math, coding, multilingual understanding, and vision.

a lot of great updates today from Anthropic! was also thrilled to get to help design and build a new prompt workbench to help people better test and iterate on prompts for claude ✨
We’re enhancing our developer experience with a new Workbench feature in the Console that makes it easier for Claude API users to test prompts. We’re also introducing system prompts, which allow users to provide custom instructions to structure responses in a more consistent way.
