MiMo-V3 is getting a new architecture. The core of it, HySparse2, is out today. Less prefill, a smaller KV cache, better long-context retrieval—and we got all three at once. Compared with MiMo-V2.6's Hybrid SWA architecture: • 5.02× lower prefill FLOPs at 1M tokens • 4.5× smaller KV cache at 1M tokens • Better MRCRv2 and RULER-v2 scores, plus lower AgentPPL and LongPPL Why build a new architecture? Agentic inference is a very different workload. Each round, a short action can return a long observation that needs to be prefilled, while the context keeps growing. That puts prefill cost, KV-cache size, and retrieval accuracy on the critical path at the same time. HySparse2 tackles all three with two levels of KV sharing: • KV Bridging: Following YOCO, full-attention layers in the cross-decoder build their K/V from self-decoder hidden states. • KV Reuse: Within each hybrid block, sparse layers reuse the preceding full-attention layer's KV cache and selection indices. Two more changes: token-level selection replaces block-level selection, and a forced window of recent tokens replaces the separate SWA branch, so local and global tokens share one KV cache. Since all cross-decoder KV caches now come from the self-decoder, prefill can stop once the self-decoder finishes. Paper: arxiv.org/pdf/2609.26368

Demand for Astra is really unprecedented. We're pulling all the levers possible to sustain the demand, but I've not seen anything like it until now and we went through very steep growth before. Priority will always be to keep excellent service for existing users, but we might have to pause new Pro subscriptions for a bit if this continues.

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

Strange as it sounds, YC wants companies it rejects to succeed. Otherwise we won't know if we reject someone good.

Chinese researchers published a paper with a devastating title: "The End of Software Engineering” it argues software engineering is finished. In traditional software, code is the carrier of pre-written human logic. In agentic software, the AI agent is the software. Code is no longer a permanent monument built by human hands. It is completely ephemeral, dynamically generated, executed, and discarded on the fly by an LLM-driven reasoning loop. Think about how software delivery has evolved: • Era 1: On-premise licensed software (you installed it locally) • Era 2: SaaS (hosted in the cloud, managed by vendors) • Era 3: Agent-as-a-Service (AaaS) Each historical shift transferred complexity away from the user. But this latest shift transfers something entirely different. It transfers decision-making complexity itself. The paper argues that traditional engineering is hitting a hard complexity wall. Human brains can only hold so much state, manage so many dependencies, and debug so many lines at once. LLM-based agents scale non-linearly. They don't just write functions faster. They navigate architectural complexity by outsourcing reasoning to models that improve every single month. Which means the role of the developer is permanently changing. You are no longer a code author typing syntax line by line. You are an intent architect. Your job is no longer writing the implementation. It is specifying goals, designing multi-agent coordination loops, and auditing outcomes.
