Obama: "We are living in a time where it can be hard to hope. Each day we wake up to some new assault on our democratic institutions. Another setback to the idea of the rule of law ... but this man - Rev. Jesse Jackson - inspires us to take a harder path ... bc if we don't step up, nobody else will"

The way to train the BioMetagenome and sequence embedding as BioNLP for large scale sequence inferences.

As tabular data and inferences.

What the white eagle doesn’t understand is that the águila real (Iztcuahtlli), the cóndor (Kuntur), and the goose (Niska) share the continent. And that they together are stronger the any bald-eagle (gringo) bully.

The future of quantum chemistry research is being redefined today.

After 8 months of exploration and hard work, we are thrilled to introduce two agents for chemistry:

⚛️ El Agente Quntur for quantum computing, and

🔬 El Agente Estructural for molecular geometry generation and manipulation.

Our second agent, El Agente Estructural (“Structural” in Spanish) is a multimodal, natural-language–driven agent for molecular geometry generation and manipulation.

Obviously a lot is going on (gestures widely)

Amid chaos, I cope by doing *something* -- anything. Lately, it's been coding for @avogadro.cc because it feels like some small change I can do myself

For *years* I've wanted to show electron density volumes .. little clouds ☁️☁️

This is the best speech, just from a pure rhetoric perspective - its sophistication and persuasiveness - that I've seen a politician deliver in a good long while. Really recommend watching or reading the whole thing.

Agreed! Based on all of this conversation, I will make a substack post and also accelerate the development of El Agente Pirata. It has many security implications that will take time to get in the hands of everybody but I agree the feature is very important.

Keep the questions coming of course! Yes, we have a planned scheme to support your local resources (El Agente Pirata) hence the name. That one, unlike Gráfico is still just a point in the roadmap with no code yet but we totally agree with the use case as a huge democratization opportunity!

Stay tuned for our paper on El Agente Gráfico. It will cover both points in some aspects and further work we are doing on El Agente Pirata will complete the vision. We should have a preprint of Gráfico soon out there!

Yes, we support GPU access in our cloud alpha. I am not clear what you mean by API access ? Access to an API to talk to the tools directly?

Happy New Year!

We began the year by reading this amazing Chemistry World article by @robinson-julia.bsky.social on how AI agents are democratising computational chemistry.

We are missing some quantum chemistry ones

Resonance
Orbital Momentum
The Exchange
The Radical
Through the double slit
The Bond
The Conical
