Meta's Inference Accelerator & Applied Optoelectronics (AAOI)

Austin recaps moderating an agentic AI panel at Synopsys Converge, then gives an in-depth technical breakdown of Meta's MTIA custom silicon. Why they're building it, how chiplets let them ship a new chip every 6 months, and how the roadmap is shifting toward gen AI inference. Vik digs into Applied Optoelectronics (AAOI), the vertically integrated Texas laser shop whose stock went from $1.48 to $100+, and whether history is about to rhyme.

Topics covered:
• Agentic AI in chip design — how it changes roles for junior and senior engineers
• Optical circuit switching and what it means for Arista's business model
• Meta's ad-serving pipeline: Andromeda, Lattice, and the GEM foundation model
• Why custom silicon (MTIA) makes sense at Meta's scale
• MTIA chiplet strategy — 4 generations in 2 years
• AAOI's vertical integration, Amazon's $4B warrant deal, and the 2017 parallel
