  What happens when you build an app so insanely
• 0:02
  popular that the millions of people using it
• 0:04
  actually force you into bankruptcy? It sounds
• 0:07
  completely paradoxical. But, you know, it actually
• 0:09
  just happened. Welcome to the Deep Dive. Today
• 0:12
  is Tuesday, October 13th, 2026. We are looking
• 0:16
  at a fundamental crisis in AI today. Today's
• 0:19
  stack of sources reveals a massive industry shift.
• 0:22
  A massive compute cost nightmare is bankrupting
• 0:26
  industry giants. Yeah, the growth at all costs
• 0:28
  era is officially dead. We are exploring the
• 0:31
  sudden collapse of character AI. We're also diving
• 0:34
  into the pivot toward hyper -efficient new architectures.
• 0:37
  And we're looking at the wild west of vibe coding.
• 0:40
  Right. It's causing absolute enterprise security
• 0:43
  nightmares for IT departments everywhere. I'm
• 0:45
  really excited to dig into these specific sources.
• 0:47
  They perfectly connect to show the maturing of
• 0:50
  consumer AI. And, well, they highlight the growing
• 0:54
  pains, too. You have this paradox where massive
• 0:57
  popularity is actually fatal. To understand how
• 1:01
  that is mathematically possible right now, we
• 1:04
  have to look at what just happened to Character
• 1:06
  AI. It is a pretty wild story, honestly. They
• 1:10
  just filed for Chapter 11 bankruptcy very recently.
• 1:12
  This is stunning when you realize they launched
• 1:15
  five years ago. They were once a wildly hot consumer
• 1:18
  tech startup. Oh, absolutely. They reached 20
• 1:21
  million monthly active users remarkably quickly.
• 1:24
  And they raised over $193 million total. But
• 1:29
  that massive engagement created massive daily
• 1:31
  inference costs. Yeah, the current financials
• 1:34
  reveal a very grim picture. They currently hold
• 1:37
  between $50 and $100 million. That covers both
• 1:40
  their liquid assets and their total liabilities.
• 1:43
  Which is not a great ratio. Not at all. Disney
• 1:46
  actually stepped in to buy some specific core
• 1:48
  assets. They agreed to pay $20 million in cash.
• 1:51
  This includes a perpetual license to their underlying
• 1:54
  technology. The platform is still running during
• 1:57
  this bankruptcy sale process, but there is currently
• 2:00
  no buyer for the entire business. If they cannot
• 2:02
  find one, it shuts down entirely. That would
• 2:05
  be a huge loss for those users. Let's frame this
• 2:09
  problem as the success penalty. Imagine running
• 2:12
  a very busy, popular local restaurant. It's an
• 2:15
  all -you -can -eat buffet, basically. Okay, I
• 2:17
  like this. Every time a customer takes a single
• 2:20
  bite, the restaurant has to buy a brand -new
• 2:23
  stove. Wow. Yeah. That is how a large language
• 2:26
  model context window works. People talk to these
• 2:30
  artificial bots for hours daily, but every single
• 2:34
  chat costs raw server compute power. That is
• 2:37
  a perfect way to visualize the underlying mechanism.
• 2:40
  Massive engagement only helps under one very
• 2:42
  specific condition. Your monetization must actually
• 2:46
  scale faster than your infrastructure costs.
• 2:49
  People formed very deep emotional bonds with
• 2:52
  these specific chatbots. They used them for everything
• 2:55
  from entertainment to deep therapy. But artificial
• 2:58
  empathy is incredibly expensive to compute. Because
• 3:02
  language models are inherently stateless by design,
• 3:05
  they do not actually remember your past conversations
• 3:07
  at all. Exactly. To create the illusion of memory
• 3:10
  and deep comfort, you have to feed the entire
• 3:13
  chat history back in. You do this every single
• 3:15
  time you send a message. And that memory requires
• 3:18
  massive parallel processing power running constantly.
• 3:22
  Every single word generated burns real electricity
• 3:25
  in a server. The model calculates the exact probability
• 3:28
  of the next word. It is doing this for 20 million
• 3:31
  active users simultaneously. The sheer electrical
• 3:34
  cost of that is completely mind -boggling. Which
• 3:37
  leads to an incredibly vicious cycle of server
• 3:39
  debt. But this raises a very obvious question
• 3:42
  about their business. Why couldn't they just
• 3:44
  cap usage or charge their most active users more
• 3:47
  to cover the server bills? Well, consumer AI
• 3:49
  markets are just far too intensely competitive.
• 3:52
  If you introduce friction, you completely kill
• 3:55
  the magic. You kill the organic viral growth
• 3:58
  you desperately need. Because they just leave.
• 4:00
  Right. If you tell a user they have run out of
• 4:02
  messages, they simply migrate to the next free
• 4:04
  available alternative. You absolutely cannot
• 4:06
  afford to lose that precious network effect.
• 4:09
  So aggressive paywalls would have instantly killed
• 4:11
  the viral growth they depended on. Exactly. Friction
• 4:15
  is death in the modern consumer app space. If
• 4:18
  massive open -ended chat models just bankrupted
• 4:20
  character AI, how is the industry fixing this
• 4:23
  compute cost crisis? The answer is extreme specialization
• 4:27
  and deep technical focus. Yeah, a total pivot.
• 4:30
  ScaleDown just unveiled a radically different
• 4:32
  model architecture recently. They call them constrained
• 4:35
  decoding models, or simply CDMs. What exactly
• 4:38
  are these models in practical terms? AI models
• 4:42
  trained to output only specific structured data
• 4:44
  formats. Think about the typical large language
• 4:47
  model used today. It is essentially a massive
• 4:50
  supercomputer trying to be human. It knows Shakespeare,
• 4:54
  quantum physics, and basic baking recipes. It
• 4:57
  uses all that generalized knowledge to answer
• 4:59
  simple questions. That is incredibly inefficient
• 5:02
  for basic data processing enterprise tasks. It
• 5:05
  is like hiring a brilliant university physics
• 5:09
  professor. You hire them just to sort your daily
• 5:11
  office mail. Right. And Scaledown realized this
• 5:14
  architecture was completely financially unsustainable.
• 5:18
  Constrained decoding models fix this fundamental
• 5:20
  structural problem beautifully. Instead of predicting
• 5:23
  any possible word in the universe, these CDMs
• 5:26
  physically restrict the pathways the AI model
• 5:28
  takes. They physically prune the unnecessary
• 5:31
  neural pathways entirely. So you don't generate
• 5:35
  freeform text token by token anymore. Exactly.
• 5:38
  These models are built for incredibly narrow
• 5:41
  specific production tasks. Tasks like fast classification,
• 5:45
  data extraction, and context compression. The
• 5:48
  performance numbers here are frankly quite staggering
• 5:51
  today. Scaledown claims up to 200 times faster
• 5:55
  inference speeds. They claim 467 times lower
• 5:59
  operating costs. It's unbelievable. This is compared
• 6:02
  to standard frontier AI software models. And
• 6:05
  they handle input contexts up to 1 million tokens.
• 6:08
  Whoa. Imagine scaling to a billion queries without
• 6:12
  bankrupting the company. It completely rewrites
• 6:15
  the fundamental rules of scaling software. The
• 6:18
  pricing makes this completely clear to modern
• 6:20
  developers. It costs about five cents per million
• 6:22
  text tokens. Wow. That is for one million text
• 6:25
  input tokens specifically. The output tokens
• 6:28
  are effectively free for your application. OpenRouter
• 6:31
  even shows a discounted rate on this right now.
• 6:34
  Oh, really? Yeah, it's roughly four cents per
• 6:36
  million input tokens currently. And they integrate
• 6:38
  perfectly with Langchain and DeepAgents today.
• 6:41
  They also work flawlessly with Langsmith directly.
• 6:44
  So you look at the newly released Gemini 4 Argon.
• 6:47
  Google just made it globally available to everyone
• 6:50
  recently. It is rolling out across all paid API
• 6:53
  endpoints right now. But you save those massive
• 6:56
  models for hard reasoning problems. You use CDMs
• 7:00
  as cheap. lightning -fast assembly line workers.
• 7:02
  They do the boring high -volume digital tasks
• 7:05
  almost instantly. Speed and cost matter much
• 7:08
  more than open -ended intelligence here. Yeah,
• 7:10
  that makes sense. Former ex -product head Nikita
• 7:13
  Beer noted something similar recently. He says
• 7:16
  technical moats are fading incredibly fast right
• 7:18
  now. The generalized models themselves are rapidly
• 7:21
  becoming cheap, basic commodities. Wait, hold
• 7:25
  on a second. I have to push back on this a little
• 7:26
  bit. If these CDMs are so restricted in what
• 7:29
  they output, won't developers find them too rigid
• 7:32
  to build creative apps? That is the counterintuitive
• 7:34
  secret of the modern software industry. Developers
• 7:37
  actually crave absolute predictability for modern
• 7:40
  production apps. Really? Yeah. Creativity is
• 7:43
  the absolute enemy of stable software systems.
• 7:46
  If you are building an app that processes digital
• 7:49
  invoices, you don't want the AI to creatively
• 7:52
  interpret the total. Oh, I see. every single
• 7:57
  time, guaranteed. You want it outputted in a
• 8:00
  strict JSON format. You want the data output
• 8:03
  to be perfectly boring. Right. Predictable, boring
• 8:06
  data is exactly what you need to build stable
• 8:08
  software. Exactly. This segment is brought to
• 8:11
  you by our partners. So we have these incredibly
• 8:14
  cheap specialized models now. The extreme cheapness
• 8:18
  of these specialized models connects perfectly
• 8:20
  here. It connects directly to a booming modern
• 8:22
  software trend today. Because compute is so cheap,
• 8:26
  Anyone can now build software. Right. You don't
• 8:29
  actually need to know how to write code. This
• 8:31
  creates incredibly powerful new enterprise tools
• 8:33
  for everyone, but it also creates a massive hidden
• 8:36
  security disaster simultaneously. We are talking
• 8:39
  about the rise of vibe coding. Let's define what
• 8:43
  this actually means in practice for you. Using
• 8:45
  natural language and AI tools to write software
• 8:48
  applications. You literally just talk to the
• 8:51
  computer in plain English. Google Play now lets
• 8:54
  users vibe code Android apps directly. You can
• 8:57
  launch them privately via Google AI Studio today.
• 9:00
  You just describe the general vibe of the app.
• 9:03
  And it hallucinates a fully functional application
• 9:06
  into existence instantly. Yeah, it's like stacking
• 9:10
  Lego blocks of data using just words. I still
• 9:14
  wrestle with prompt drift myself when vibe coding.
• 9:18
  It is profoundly difficult to keep the underlying
• 9:20
  logic stable. You fix one bug and the AI breaks
• 9:23
  three other features. Right. And this brings
• 9:26
  us to the serious corporate fallout because it's
• 9:29
  not just hobbyists building little weather apps
• 9:31
  anymore. Pluto Security just raised $42 million
• 9:35
  very recently. That's a massive series raise.
• 9:38
  They are specifically tackling AI -related enterprise
• 9:41
  network security risks today, and they found
• 9:44
  something genuinely terrifying in their recent
• 9:47
  corporate data. 60 % of enterprise AI risks come
• 9:51
  from vibe -coded tools. Wow. Yeah. 60 %? Yeah.
• 9:55
  These are tools built entirely by non -developers
• 9:59
  internally today. Finance teams are actually
• 10:03
  the worst security offenders here. Let's really
• 10:05
  dig into how this actually happens internally.
• 10:08
  Imagine you are a senior financial analyst at
• 10:10
  a corporation. You want to automate a massive,
• 10:14
  complex quarterly spreadsheet. You don't know
• 10:16
  how to write Python code at all. So you just
• 10:19
  ask an AI agent to build it. The AI generates
• 10:22
  thousands of lines of highly complex code. It
• 10:25
  runs perfectly. and saves you countless hours
• 10:27
  of work. You look like an absolute genius to
• 10:30
  your department boss. But the code also secretly
• 10:32
  exposes the company database externally. It might
• 10:36
  hardcode API keys directly into the plain text.
• 10:39
  The analyst has absolutely no idea it is highly
• 10:43
  vulnerable. None at all. They just know that
• 10:46
  the internal application works perfectly today.
• 10:49
  This is known as shadow IT in the corporate world.
• 10:52
  But it's shadow IT on an unprecedented global
• 10:55
  scale now. You cannot expect a non -developer
• 10:59
  to patch system vulnerabilities. They don't even
• 11:01
  know what a security vulnerability actually is.
• 11:04
  Pluto Security saw this exact pattern happening
• 11:06
  absolutely everywhere now. It's wild. We are
• 11:09
  entering a massive IP and ethics wild west. The
• 11:13
  strict lines between building and using software
• 11:16
  are blurring. Look at what SpaceX AI just bundled
• 11:19
  together very recently. They bundled X -Premium,
• 11:22
  Grok, and Cursor all together. all your AI agents
• 11:25
  and coding tools under one bill. It democratizes
• 11:29
  software creation for the average person completely.
• 11:32
  But the sheer potential for digital fraud is
• 11:34
  also escalating. Did you see the story about
• 11:36
  the music fraudster recently? A man just got
• 11:39
  18 months in federal prison. Oh, I saw that.
• 11:42
  He made $8 million just from purely artificial
• 11:47
  bot streaming numbers. Yeah, it is a seriously
• 11:50
  wild and... deeply complex criminal scheme he
• 11:53
  used 10 000 automated bots for his entire operation
• 11:56
  he programmed them to mimic real human listening
• 11:59
  patterns online they streamed his ai generated
• 12:02
  songs billions of times continuously he collected
• 12:05
  eight million dollars in fake streaming royalties
• 12:08
  total that is just incredible it shows how these
• 12:10
  tools scale malicious behavior completely effortlessly
• 12:14
  We also see major IP legal battles continuing
• 12:17
  today. A judge just ordered OpenAI to hand over
• 12:20
  internal records. These are hiring records tied
• 12:23
  to former Apple employees specifically. It is
• 12:26
  part of a massive ongoing trade secrets legal
• 12:29
  case. Apple now gets faster access to these private
• 12:32
  company messages. We are simply observing the
• 12:35
  rapidly shifting legal landscape here. The legal
• 12:38
  frameworks are desperately struggling to keep
• 12:40
  pace currently. The entire AI -empowered new
• 12:43
  app ecosystem is evolving incredibly fast. OpenCode
• 12:47
  2 .0 now lets you code with an open -source agent.
• 12:50
  Oh, that's interesting. You can run it directly
• 12:51
  from your local computer terminal. Muse Wonder
• 12:54
  brings Meta's most highly capable AI models forward.
• 12:57
  They provide deep expert knowledge in complex
• 13:00
  law and finance. Mention Bird helps your brand
• 13:02
  get mentioned by Claude directly now. Kai handles
• 13:05
  your daily emails and schedules your corporate
• 13:07
  meetings. With finance teams secretly building
• 13:10
  risky AI tools, how does a company even begin
• 13:13
  to audit code that no human actually wrote? Well,
• 13:17
  this is exactly why companies like Pluto Security
• 13:19
  exist today. You simply cannot audit the hallucinatory
• 13:23
  AI code itself easily. It is just too massive
• 13:25
  and it changes far too frequently. Right. You
• 13:28
  must monitor the actual AI agent behavior instead.
• 13:31
  You watch what the code physically tries to access
• 13:34
  internally. You put guardrails around the database,
• 13:37
  not around the code. Got it. So we need AI security
• 13:39
  guards to watch the AI programmers. Let's bring
• 13:43
  all of this together right now. We are clearly
• 13:46
  moving past the growth at all costs era. The
• 13:49
  bankruptcy of character AI proves this point
• 13:52
  incredibly clearly. Big, expensive, open -ended
• 13:56
  general models aren't sustainable for everything.
• 13:59
  You can't just burn compute for massive scale
• 14:01
  anymore. The future definitely belongs to tools
• 14:04
  like scaled -down CDMs. They are hyper -fast,
• 14:08
  incredibly cheap, and highly specialized software
• 14:11
  models. We don't need a massive generalized brain
• 14:14
  for every task. We just need extremely efficient
• 14:17
  digital workers doing narrow tasks. Non -developers
• 14:20
  are using them to vibe code highly custom solutions.
• 14:23
  They're doing this despite the massive hidden
• 14:26
  network security risks. And we're now racing
• 14:28
  to intelligently secure the chaos they create.
• 14:31
  If models are becoming 400 times cheaper and
• 14:34
  anyone can vibe code an app. What happens to
• 14:38
  the value of software when creating a custom
• 14:41
  app costs less than the electricity required
• 14:43
  to run it? That's a great question. Thank you
• 14:47
  for joining us on the Deep Dive today. Keep questioning
• 14:49
  the information you constantly see around you.
