The Sequence AI of the Week #793: DeepSeek's New Paper: Storing 100B Parameters on CPU RAM

TheSequence • 21 implied HN points • 21 Jan 26
🕹 Technology Hardware
  1. The current LLM trend is to scale models huge and use sparsity tricks like Mixture-of-Experts so only a small part of the model activates per token, reducing FLOPs.
  2. Reusing an old technique — storing large, static lookup-like memories on CPU RAM and conditionally accessing them — can let models hold around 100B parameters off-GPU and avoid expensive dense computation.
  3. The key insight is that many LLM costs come from simulating static lookup tables with neural computation, so replacing that simulation with real conditional lookups makes models much more efficient.

Time to First Token

Kesav’s Lab • 8 implied HN points • 26 Jan 26
🕹 Technology Hardware
  1. Using an inference provider gets you serverless endpoints, streaming, and time-to-first-token optimizations fast and is great for experimentation, but it sacrifices control over data residency and token logging. Building your own infra gives maximum control and compliance but is costly, slow to provision, and requires tradeoffs between speed, quality, and price.
  2. Provisioning large GPU instances is as much political and logistical as it is technical — expect weeks of lead time, enterprise support, and close coordination with cloud vendors to get high-end capacity. Tools like managed notebooks speed prototyping, but real deployments involve lots of debugging and operational overhead.
  3. TechBio workloads need specialized compute and tight lab-in-the-loop integration, which opens a market for domain-specific inference platforms that help fine-tune models and evaluate clinical viability. Because downstream clinical validation is slow and expensive, models that focus on toxicology and clinical outcomes are especially valuable for capturing real-world ROI.
