Today we announce our $100M seed round to redefine how humanity computes in AI's next chapter.

The future of compute and AI is heterogeneous. Callosum is building it:

are you ready to grow some brains? 🧠

Project A & @outlierlabshq are hosting a biocomputing hackathon with @CallosumAI and Frontier Computing (YC S26) @frontiergpu @MichaelDmrks!

come program living brain cells to control robots, fly drones, and build something crazy.

50 spots only.

AI inference is shifting from single GPU clusters to Heterogeneous Disaggregated Inference. Prefill (compute-bound) and Decode (memory-bandwidth-bound) have completely opposite hardware needs. Instead of forcing H100s/B200s to do both (poorly), the industry is splitting the pipeline across specialized chips.

Today’s guest is @achterbrain , co-founder and CTO of @CallosumAI .

Jascha’s bet is that the future of compute is heterogeneous: different chips working together on different parts of a problem.

Beyond the multichip future, we discuss:

- What neuroscience taught Jascha about designing computing systems

- How chipmakers discover what their hardware is best at

- Where thermodynamic, biological, and quantum computing could fit

- Hiring people who welcome having their ideas challenged

- Building an AI infrastructure company in London

SoTA Scientific Parallelism Hackathon | 21st-22nd November | London

Which scientific questions could we investigate better if computation were faster or could run at a greater scale?

The Society for Technological Advancement (@sotalikesfuture), supported by Callosum (@CallosumAI), Inherent Labs (@inherent_labs), the Advanced Research + Invention Agency (@ARIA_research) and Fractile (@fractile_ai), is holding a hackathon to tackle open scientific questions that could benefit from faster computation or experiments at a greater scale.

Contestants will use parallel computing on challenges across biology, chemistry, physics, materials science, astronomy, and Earth sciences – pushing GPUs to their limits and rethinking architectures for this new paradigm.
