    Cerebras's decade: the wafer-scale bet, G42 and CFIUS, OpenAI's $20B inference deal, IPO popCerebras十年史：晶圆级芯片赌局、G42与CFIUS风波、OpenAI 200亿美元推理合同与上市首日暴涨more
    • Wafer-scale yield became a manageable engineering problem
      • Cores shrunk to 0.05mm², ~1% of an H100 SM, 100x defect tolerance
      • 1-1.5% spare cores plus on-chip fabric routes around ~46 defects
    • Inference's serial nature ends up favoring Cerebras
      • Decode moves weights and cache per token; memory bandwidth is bottleneck
      • Memory and compute on same silicon gives thousands of times GPU bandwidth
    • Prefill and decode should run on different chips
      • Prompt processing parallelizes; answer generation is strictly serial
      • AWS deal: their training chips do prefill, our wafer does decode
    • We'll partner with every hyperscaler except Nvidia
      • Their silicon handles part of the problem, ours handles the rest
      • Combined solution beats any single supplier
    • G42 both saved Cerebras and killed its first IPO
      • G42 was over 83% of 2023's $78.7M revenue, 87% in H1 2024
      • CFIUS opened a national-security review; company withdrew its S-1
    • Proving the tech isn't enough; deep tech needs a paying anchor customer
      • First-gen WSE sold barely a dozen units, second-gen about 300
      • Two or three years ahead of market; nobody cared how fast we were
    • We dodged the three tightest AI chip supply bottlenecks
      • No HBM, no CoWoS advanced packaging, no TSMC 3nm line
      • But entire roadmap still rests on TSMC 5nm capacity
    • Speed creates entirely new applications, not just nicer UX
      • Over 2,000 tokens/sec versus 200-300 for conventional stacks
      • Hover-to-callgraph, live whiteboard tutoring, AI scientist searching papers mid-meeting
    • Falling gross margin is a deliberate choice, not eroding advantage
      • Renting back already-sold systems in Q2-Q3 costs 10-15 margin points
      • Full-year guidance runs 10 points above original plan
    • OpenAI's in-house Jalapeño chip is a long-term threat
      • Inference ASIC built for language models, part of full-stack self-reliance
      • Cerebras must prove its speed edge is durable and irreplaceable
    • Scaling Law was the real basis for the 2016 wafer-scale bet
      • Baidu's 300M-parameter model took three months; gains predictable and linear
      • Researchers foresaw models far past 500M params, beyond GPU clusters
    • 晶圆级良率难题被拆成可管理的工程问题
      • 核心缩到0.05平方毫米，约H100单核的1%，容错能力百倍量级
      • 多放1%-1.5%备用核心，片上网络动态绕开约46处缺陷
    • 推理时代的串行性反而成就了Cerebras
      • decode每生成一个token都要搬动权重与缓存，瓶颈是内存带宽
      • 内存与计算在同一片硅上，带宽达GPU数千倍量级
    • prefill和decode该用不同芯片分工
      • 处理prompt可并行，生成答案严格串行
      • 与AWS合作：其训练芯片做prefill，Cerebras晶圆做decode
    • 除英伟达外，我们愿与所有超大规模云厂商合作
      • 拿别人的芯片处理推理的一部分，自己做另一部分
      • 组合方案比单一供应商更强
    • G42既救了Cerebras，也毁了它第一次上市
      • 2023年营收7870万美元中G42占超83%，2024上半年升至87%
      • CFIUS就阿联酋客户启动国安审查，公司主动撤回S-1
    • 技术验证不够，深科技硬件必须有大客户真金白银部署
      • 第一代WSE只卖出十几台，第二代约300台
      • 走在市场前面两三年，速度再快也没人在乎
    • 我们避开了AI芯片行业最紧张的三个供应瓶颈
      • 不用HBM、不用CoWoS先进封装、不用台积电3纳米产线
      • 但5纳米产能仍是命门，全部产品链建在其上
    • 速度提升会创造全新应用形态，而非只是体验优化
      • 每秒超2000 token，传统方案约200-300
      • 悬停即出调用图、实时板书教学、开会时同步检索论文的AI科学家
    • 毛利率下滑是主动选择，不是技术优势被成本吃掉
      • 二三季度从客户手中把已售设备租回，影响毛利率10-15个百分点
      • 全年指引比原计划高出10个百分点
    • OpenAI自研Jalapeño是Cerebras的长期威胁
      • 专为语言模型推理设计的ASIC，全栈自控战略一部分
      • Cerebras必须证明推理速度长期不可替代
    • Scaling Law是2016年押注晶圆级引擎的真正依据
      • 百度3亿参数模型训练要三个月，提升可预测且线性
      • 研究员预判十年内模型远超5亿参数，现有GPU集群量级不够

  13. Dwarkesh Podcast media
    Dwarkesh on continual learning: safety regulation, lab moats, and why personalized weights favor big firmsDwarkesh谈持续学习：安全监管、实验室护城河，以及个性化权重为何利好大公司more
    • Session-to-session markdown notes can't replace real continual learning
      • like infinite saxophone students passing notes, none ever plays it
      • skills must accumulate in weights, not text handoffs
    • Pre-deployment safety checks will stop being a meaningful category
      • model may update daily from millions of work sessions
      • monthly or quarterly risk inspections fit better than one gate
    • Locking in AI safety regulation now is dangerous
      • technology unknown even one year out
      • risk of freezing an archaic, counterproductive approach
    • Alignment research ignores the constant-weight-update case
      • current work only asks whether frozen weights behave
      • pooled learning lets users inject backdoors into base model
    • Continual learning increases diversity of AI minds, a net good
      • today under five base models, all trained on similar data
      • experience differs per company and per instance, breaking mode collapse
    • Labs can no longer sit on their best model
      • Anthropic reportedly ran Mythos internally February to June
      • competitor shipping a worse model gains real-world experience faster
    • Continual learning gives labs the moat they now lack
      • switching means firing an employee with months of org context
      • cloud margins are high because switching is costly, per Dario
    • Labs will pay for, and gate access on, training rights
      • already visible in discounts to new coding-product users
      • best models withheld from enterprises refusing session training
    • Personalized weights economically favor large organizations
      • sparse models like DeepSeek v3 want 2400+ concurrent sequences
      • batch-size-one individual user suffers 100x worse compute efficiency
    • 靠会话间写markdown笔记替代不了真正的持续学习
      • 就像无数学生轮流进琴房传笔记，没人能吹好萨克斯
      • 技能必须沉淀进权重，而非文本交接
    • 部署前安全检查将不再是一个有意义的环节
      • 模型可能每天根据数百万次工作会话更新
      • 按月或季度做风险检查比设一个关卡更合适
    • 现在就把AI安全监管框架定死很危险
      • 一年后的技术形态都无法预知
      • 可能锁定一套过时甚至有反作用的做法
    • 对齐研究几乎没碰权重持续更新这一情形
      • 现有工作只问冻结权重在部署中是否听话
      • 跨用户汇总学习会让用户往基础模型里塞后门
    • 持续学习会增加AI心智的多样性，这是好事
      • 当今不到五个基础模型，训练数据大致相同
      • 经验因公司和实例而异，打破现在的模式崩塌
    • 实验室再也没法把最强模型压在手里
      • 据称Anthropic的Mythos二月内部使用、六月才公开
      • 对手发布日上线较弱模型，却靠真实经验更快变聪明
    • 持续学习会给头部实验室带来目前缺失的护城河
      • 换模型等于辞掉积累数月组织上下文的员工
      • Dario类比云厂商：高毛利来自迁移成本高
    • 实验室会补贴用户、也会用断供换取训练授权
      • 编程产品给新用户的优惠折扣已是如此
      • 拒绝授权会话数据的企业拿不到最强模型
    • 个性化权重的经济性明显偏向大型组织
      • DeepSeek v3这类稀疏模型最优批量超2400条并发序列
      • 批量为一的个人用户算力效率差两个数量级以上

    Sarah Guo and Elad Gil on trillion-dollar math, RSI timelines, compute oligopoly, California exodusSarah Guo与Elad Gil谈万亿公司算术、RSI时间表、算力寡头与加州出逃more
    • Few more trillion-dollar companies will emerge in the next three to five years
      • Needs $50-100B revenue at good margin, very few markets support that
      • Past five years were punctuated equilibrium, not the new normal
    • Investors are conflating market size with speed of getting there
      • Physical-goods plays like energy and robotics lack footprint to scale that fast
      • People invest as if velocity to a trillion is proven
    • The best new founders are picking niches out of fear of labs
      • Flight to hardware, American dynamism, inference-cloud features labs 'would never do'
      • Harvey, Decagon, Sierra entered huge markets on labs' roadmaps and won

      • One AI year equals three to four normal cycle years
      • Pre-scheduling removes emotion and blame from who raised it
    • Financing gets easier, not harder, from here
      • Huge returns mean bigger funds that must deploy capital

    • The 18-month RSI timeline is a poor predictor
      • Smart researchers have said 18 months away, every 18 months, for five years
      • Gathering data for less verifiable domains is the hard part, not algorithms
    • Compute scarcity enforces an oligopoly among the big labs
      • Roughly pro-rata compute caps how fast any single lab can progress

    • Compute prices must rise sharply to bridge the revenue-vs-compute growth gap
      • lab revenue 10x/yr but compute only 3x/yr — margins alone can't close gap
      • 90%+ margins unlikely to persist against competition; rising compute prices are the escape valve
    • Smarter models will price out consumer AI use cases
      • frontier labs will outbid consumers for tokens to automate AI research
      • H100 could justify 15x current spot price if running human-level software engineer
    • 3x annual compute scaling is hard to sustain, let alone accelerate
      • Moore's Law, new fab construction, and wafer-share gains each near their limits
      • AI wafer share at TSMC N3 nodes approaching ceiling (~86%) by end of next year
    • 算力价格必须大幅上涨，才能弥合营收与算力增速的差距
      • 实验室营收年增10倍，算力仅增3倍，单靠提升利润率无法填补缺口
      • 超过90%的利润率难以在竞争中维持，算力涨价是唯一泄压阀
    • 更智能的模型将把消费级AI应用挤出市场
      • 前沿实验室愿意为自动化AI研究支付更高的token费用，胜过普通消费者

    • Quantizing more layers can raise fidelity, not lower it
      • errors of chosen layers cancel out in final logit distribution
      • proved by KL divergence; 20% more quantized than Nvidia's, faster too
    • Repeated-token collapse is a software bug, not the weights
      • same weights on a different inference engine don't loop
      • kernel race exposed only on clusters with slower node-to-node KV transfer
    • Stacked optimizations give 4-10x over off-the-shelf serving
      • NVFP4 ~2x, speculator ~2x, PD disaggregation ~2x
      • baseline trillion-param model on stock engine runs 30-40 tokens/second
    • I'm bearish on mega-kernels
      • writing a truly optimized one is extremely hard; teams rarely ship them
      • separately optimized TRT-LLM and Modular kernels end up faster
    • Rubin turns inference into an infrastructure problem
      • more emphasis on CPU-GPU and GPU-GPU interconnect
      • KV offloading, cache-aware routing, disaggregation become the valuable work
    • GPUs are drifting toward ASICs, undercutting AI-ASIC startups
      • specialized tensor cores, TMAs, instructions shaped to today's head dimensions
      • weights etched into silicon go stale within a month or two
    • Interconnect, not kernels, blocks 100x faster inference
      • KV cache moves node-memory then HBM, two-stage transfer bottleneck
      • fast enough NICs would give ~100x on disaggregated serving
    • Long-form video generation must go autoregressive
      • 5s of 480p is already 35k tokens, attention quadratic beyond
      • sparse attention wrecks quality; chunk-stitching drifts darker to black screen
    • 100x cheaper open video models still lose to closed ones
      • media companies pay $1000 for Veo or Kling cuts anyway
      • weak demand means fewer open checkpoints; latest Wan releases went closed
    • Continual learning lands on KV cache compaction, not weight edits
      • edited weights fix one-hot facts but fail second-order reasoning questions
      • compacted near-infinite KV keeps knowledge and leaves inference stack unchanged
    • Dedicated endpoints beat shared APIs for domain-tuned speculators
      • draft model trained on your traffic hits near-perfect acceptance
      • shared endpoint can't know if you're coding or summarizing Harry Potter
    • Open weights let you mix components across labs
      • Kimi vision encoder grafted onto GLM-5.2 by training only the projector
      • result: Kimi vision, GLM weights, DeepSeek attention in one model
    • 多量化几层反而可能更忠实原模型
      • 所选层的量化误差在最终 logit 分布上互相抵消
      • 用 KL 散度验证：比 Nvidia 的量化多压 20%，还更快
    • 反复输出同一 token 是软件 bug，不是权重问题
      • 同样权重换个推理引擎就不复现
      • kernel 竞态只在节点间 KV 传输较慢的集群上暴露
    • 叠加优化能比开箱即用快 4 到 10 倍
      • NVFP4 约 2 倍、speculator 约 2 倍、PD 分离约 2 倍
      • 万亿参数模型在原生引擎上基线只有每秒 30-40 token
    • 我对 mega-kernel 不看好
      • 写出真正高效的极难，做了的团队多半不上生产
      • 分开各自优化的 TRT-LLM、Modular kernel 反而更快
    • Rubin 时代推理更像基础设施问题
      • 更强调 CPU 到 GPU、GPU 之间的互联
      • KV 卸载、按缓存路由、PD 分离成为最有价值的活
    • GPU 正在往 ASIC 靠，AI ASIC 创业逻辑变弱
      • 专用 tensor core、TMA，指令形状贴合当下模型的 head 维度
      • 权重烧进芯片一两个月就过时
    • 挡住百倍推理提速的是互联，不是 kernel
      • KV cache 要先进节点内存再进 HBM，两段搬运成瓶颈
      • 若 NIC 足够快，分离式服务可提速近百倍
    • 长视频生成必须走自回归
      • 5 秒 480p 已是 3.5 万 token，注意力还是平方增长
      • 稀疏注意力伤画质，分段拼接会逐段变暗直至黑屏
    • 开源视频模型便宜百倍也抢不过闭源
      • 影视公司宁愿花 1000 美元用 Veo、Kling 剪片
      • 需求少导致开源 checkpoint 更少，最新 Wan 版本已闭源
    • 持续学习的落点是 KV cache 压缩，不是改权重
      • 改权重只能塞进单点事实，二阶推理问题答不对
      • 压缩后近乎无限的 KV 保住知识，推理栈几乎不变
    • 专属端点在定制 speculator 上胜过共享 API
      • 按你的流量训练的草稿模型接受率接近满
      • 共享端点无法预知你是写代码还是总结小说
    • 开源权重让人跨实验室拼零件

    • Inference serving has no losers
      • new inference providers keep appearing, none shrinking from competition
      • everyone grows in step
    • Infra is the product, not a support role
      • model- and product-first companies compromise on infra's aesthetics
      • infra teams stay undervalued, forced into hacky patches for others
    • Base models should count as part of infra
      • the toolbox includes codebases, sandboxes, environments, intermediate checkpoints
      • combining them is how you keep producing task-specific models
    • SGLang and vLLM differ in focus but will converge
      • SGLang went into thousand- and ten-thousand-GPU production serving earlier
      • vLLM covered community and long-tail model support earlier
    • Formal verification's real-world reach is too narrow
      • verifying a program costs far too much
      • what can be verified is tiny, so impact stays small
    • Shared prefixes exist in nearly every serving scenario
      • multi-turn chat necessarily reuses prior history
      • agentic and complex workloads make prefix sharing more common
    • The hard part of AI infra is the team, not technical change
