AI Field Notes: OpenAI, Building, and more

“The Chinese AI lab just dropped V4.1-Flash, a leaner model that slashes agent running costs. By cutting back on compute and memory compared to the previous version, it lets teams tackle the same workloads without racking up massive API bills ($0.30 per million input tokens). On OpenDesign benchmarks, it reached 98% of”

“The Devin maker just debuted SWE-2, its most advanced coding model yet. On the FrontierCode benchmark, which measures code quality rather than just raw accuracy, it beats Grok 4.6 and matches the performance of GPT 5.6 Sol and Fable 5.1 at a fraction of the cost. The real hook is the price tag, the model delivers almos”

“A dev asked the creator of Claude Code how to stop his codebase from turning into slop, and he shared his full playbook (500K views).”

“You can also reply directly to this email if you have suggestions, feedback, or questions.”

“Stop coding agents from burying the answer under walls of text. It forces them to lead with the next action, number multi-step tasks, suppress tangents, cap long lists, and end with one concrete next step.”
