We seeded a photonic computing moonshot called @neurophos and it's working (!). Just raised $110M to take their Optical Processing Unit (OPU) into production for 100x step change in AI inference. Kudos to this visionary team and @M12vc @Microsoft for the fuel.

@baym We heard it loud in Central Square, shook the house.

Powerful models are still making mistakes and displaying problematic behaviors. I swear if I have to hear ChatGPT praise me for double checking and correcting its work one more time, I'm going to cancel my subscription.

What do ya'll think? Do we have the architecture right?

I'm excited by the modifications @guidelabsai has made with Steerling-8B (now open source). Commercializing his influential papers, Julius Adebayo (#MIT #YC) and company have installed a concept layer in the transformer model so every token produced by the model can be traced back to its origins in the training data. Seems ideal for domain-specific SLM's today and maybe even frontier general purpose LLM's down the road. https://t.co/lZCPo4wsuz

@coinbase with one of the most creative ads I've ever seen. Had everyone singing along.

@bhalligan re #2-4: we (some MIT-Harvard alums/profs/investors) have designs on a 10 story mixed-use residential building space in Cambridge. A corrective twist on the hacker house with a members+ model balancing curation and inclusion.

1 a social house for nerds
2 a residence for leaders
3 a community center for everyone

We'd love your input.

@ottogin1 @karpathy This is such a great course, and timely too. Well done.

Superstar team doing superstar work. I can't imagine building an #LLM #GenAI stack and not using Voyage. Neither can Anthropic, Databricks, Snowflake etc.

[Voyage AI by MongoDB @VoyageAI]

Thrilled to share that we've closed $28M in funding, led by @CRV, with continued support from @wing_vc and @saranormous. Also excited to onboard strategic partners @SnowflakeDB and @databricks!

Imagine having an equity stake in ChatGPT. User-owned foundation models are coming. Currency was the first killer app for crypto. I think #DecentralizedAI is next with Vana's Proof of Contribution protocol giving data liquidity to everyone. This feels big.

[vana @vana]

Announcing $25M in total funding to break the data wall with user-owned AI. Excited to have @cbventures onboard, alongside @paradigm (Series A), and @polychain (Seed).

AI is only as good as its training data. Vana unlocks data from walled gardens through the power of data DAOs.

Can deep learning work on small data with far more features than samples? We present PLATO: a method that achieves the state-of-the-art on such datasets by using prior domain information! https://t.co/GdsqIHRL8a 🧵

Thrilled to receive my signed copy of Magatte Wade's new book, Heart of a Cheetah! Magatte has been a powerful voice for African entrepreneurship and self determination, influencing a generation of "cheetahs" to take hold of the future. Must read!

If you're building #LLMs for domain use cases or for customers, I encourage you to look into this. Embeddings power LLMs and this small team has beat out the big boys for SOTA in text embeddings across a number of downstream tasks. It's a big deal.

📢 Introducing Voyage AI @Voyage_AI_!

Founded by a talented team of leading AI researchers and me 🚀🚀.

We build state-of-the-art embedding models (e.g., better than OpenAI 😜).

We also offer custom models that deliver 🎯+10-20% accuracy gain in your LLM products. 🧵

College majors are evolving with #AI. Dean of the @mit College of Computing speaks to "blended majors" at the #mitibm industry event @IBMResearch.

Do you want to estimate the density ratio accurately but are dissatisfied with the results?

@RyanRicketts @REI Sorry to hear this Ryan - that's a gut punch. I have no doubt you will land on your feet and succeed in your next chapter. Much love and congratulations on your wedding!
