Tamarin Bay, Mauritius: one of the best e-foil spots on the island Why Tamarin? The Rivière du Rempart meets the ocean here, which leaves a natural opening in the reef. Walk in a few metres and you’re up and foiling, with no rocks or coral to worry about. It’s ideal for beginners and experienced riders alike. On this perfect morning, we had the bay to ourselves. Glassy conditions, crystal-clear turquoise water, nobody else around. Rider: Jorgen Setup: Board: @fliteboard Pro, Soft Top (Saltbush) Propulsion: Jet2 Front wing: Wave 850 Back wing: Cruiser Jet 300 Video setup: DJI Avata 360 📍 Location: Tamarin Bay, west coast of Mauritius 🏄 Want to try e-foiling in Mauritius? @efoilmauritius

@grok explain what these symbols are. Why are the popping up now everywhere? Why does it look like a bug?

Does it matter if secrets were "sealed" on railway? Everything exposed?

Coding is solved. Building good products not.

Yesterday, I was celecrating the voice chat function fo @bot. Today, the content of a voice call of 15 minutes just vanished 😣
Just used the voice chat function in @bot for my first weekly checkin with my CoS. I love it!

I switch from hermes to grok bot ~5 weeks ago. Loved the on-boarding experience. But got annoyed my the the model and grok 4.7 was disappointing. Started migrating to hermes again. Now, grok bot is using anthropic models, too, I should hop back to grok bot...
I stopped using Hermes, finished migrating everything to Grok Bot now Grok Bot is just too good!

How to get Jev out of my timeline again?

I have an energy analytic platform. AI was helping me a lot to introduce new features. But it also needs a lot of maintanence and still quite buggy. I lean more and more to the @salesforce approach: Headless service offering, agents first, humans oversee in their favorite UI.

Just a hyped launch? We will find out soon. First you have to know: Jev is not an LLM. But it is a super fast and cheap judge. My favorite use cases:
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

You have to know: Jev doesn’t chat. You give it state + typed questions (pick one / score / yes-no). It returns labels and calibrated probabilities in one fast pass.

For example: User: “Can you fix it?” Jev Choice: {ready, need_clarification, off_topic} → need_clarification (0.86) App asks: “Fix what—the login error, the invoice, or something else?” No chat model runs until the ask is clear.

Can't wait to test it

What? @cursor_ai bugbot used all my "other model" tokens of the Ultra plan in 2 days 🙄 This is fucked up! Didn't even know it exists or was activated. How to deactivate this money draining thing?

How is Atra doing?
I didn't think to give Astra access to my Gmail and Notion until today. Immediate thoughts: holy sh*t this might actually be AGI...
