Slow Developer Experience Will Bottleneck Fast Models
博客要点 (中文)
Sean Goedecke 2026-09-14 工程短文。中心论点：当模型 tok/s 还在 60 上下时 DevEx 是秒级的事，瓶颈是思考和等待；Taalas 的 LLaMA-3.1-8B 已经在 17,000 tok/s 下做到「回车即出」，未来当快速模型被接成 subagent 后，每 100ms vs 10ms 文件读取、500ms vs 2s 测试循环都会被放大成「分钟级等待 vs 即时响应」差距。预言 2020 年代末重新出现一波 DevEx 团队，但服务对象变成 agent——优先选编译快、依赖轻的语言（点名 Golang），把 dev loop 调到极致。这条对在 2026 年还把 DevEx 当 2010 年代遗物砍掉的团队是提醒：当 agent 接管大部分代码动作后，开发体验的瓶颈会从「人开心」变成「agent 不会因为慢而退化」。
Key claims (English)
Sean Goedecke's 2026-09-14 engineering short makes a concrete forecast. With models at ~60 tok/s, DevEx is a second-scale affair and the bottleneck is thinking + waiting. Taalas's LLaMA-3.1-8B already runs at 17,000 tok/s — 'press enter, get output'. When those fast models are wired up as subagents, the 100 ms vs 10 ms file read or 500 ms vs 2 s test loop multiplies into 'minutes of waiting vs instant response'. Goedecke predicts a new wave of DevEx teams in the late 2020s, but the customer is now the agent — favor fast-compiling, dependency-light languages (Golang gets a call-out) and tune the dev loop to extremes. The note is a wake-up call to teams still treating DevEx as a 2010s artifact: once agents do most code actions, the bottleneck moves from 'human happiness' to 'agent not degrading under latency'. Specific: tok/s, model name, and frameworks are all spelled out.
