    E4
    DeepSeek is a Game Changer for AIAn AI model that changed the fortunes of silicon valley overnight. Deep Seek has been released open source, and requires far less hardware and investment. Mike Pound is based at the University of Nottingham.
  • How CPU Memory & Caches Work
    E5
    How CPU Memory & Caches WorkRelatively speedy-to-access cache saves your computer having to trudge over to the RAM, but with multiple levels of cache memory, how does it all work?
  • Finding The Slope Algorithm (Forward Mode Automatic Differentiation)
    E6
    Finding The Slope Algorithm (Forward Mode Automatic Differentiation)The algorithm for differentiation relies on some pretty obscure mathematics, but it works! Mark Williams demonstrates Forward Mode Automatic Differentiation.

    E9
    Carbon: (C++)++ ? Can Carbon De-Throne C++?Carbon is a brand new programming language still under development. It aims to dethrone C++ by being interoperable & compatible in both directions. Dr Guiffreida from the University of Nottingham gives us the lowdown on this ambitious new programming language.
  • Behind the Scenes at GTC AI Conference
    E10
    Behind the Scenes at GTC AI ConferenceGTC AI Conference is held each year by Nvidia and showcases AI and related technologies. This year Computerphile visited, here's a taste of what we saw. Full interviews coming soon, and yes, we did speak to him!

  • Ai Will Try to Cheat & Escape (aka Rob Miles was Right!)
    E12
    Ai Will Try to Cheat & Escape (aka Rob Miles was Right!)As Large Language Models improve, the tokens they predict form ever more complicated and nuanced outcomes. Rob Miles and Ryan Greenblatt discuss "Alignment Faking" a paper Ryan's team created - ideas about which Rob made a series of videos on Computerphile in 2017.
  • Reputation Lag Attack
    E13
    Reputation Lag AttackDiscussing how scammers take advantage of the way certain online systems work to leverage the delays. Dr Tim Muller is based at the University of Nottingham.
  • Shortest Path Algorithm Problem
    E14
    Shortest Path Algorithm Problem A seemingly simple problem that's "in general" incredibly difficult! CEO of Redwood Research Buck Shlegeris explains his favourite algorithmic fact!
  • What is Cuda?
    E15
    What is Cuda?What is Cuda and why do we need it? An Nvidia invention, Cuda is used in many aspects of parallel computing. We spoke to Stephen Jones, one of the architects of Cuda at the recent GTC conference.
  • Is this AI's Version of Moore's Law?
    E16
    Is this AI's Version of Moore's Law?Research suggests the rate at which AI is able to stay 'on task' is doubling every seven months. Is this the AI equivalent of Moore's Law? - Sydney Von Arx works on adversarial stress-testing at METR (Model Evaluation & Threat Research.)
  • Subroutines in Low Level Code
    E17
    Subroutines in Low Level CodeBashing out low-level code, it can be annoying to re-type the same commands over and over when you need to repeat a routine. Matt Godbolt explains how we can save frequently used code as a subroutine and reuse whenever its needed.
  • Hash Collisions & The Birthday Paradox
    E18
    Hash Collisions & The Birthday Paradox Mike Pound discusses hash collisions & the birthday paradox

    E19
    Forbidden' AI TechniqueThe so-called 'Forbidden Technique' with Chana Messinger
  • AI Sandbagging
    E20
    AI SandbaggingFollowing the theme of AI research and safety, Aric Floyd talks about how some Large Language Models might follow the all too human trait of sandbagging - "lying" about their true capabilities.
