IBM TechnologyThe Model Wars Are Over—Customization Is the New Moat
Inkling’s open-weight fine-tuning platform vs. Muse Spark’s agent focus: The model race is no longer about benchmarks but who gives teams the most control.
AI EngineerExecution Is Cheap—Your Eval Design Will Make or Break Success
An AI agent won a coding competition by executing human ideas, signaling execution is automated. High-leverage work shifts to evaluation design, architecture.
Theo - t3․ggYour Model Is Fine, Your System Prompt Is Sabotaging You
Codex’s hidden system prompt mandates specific border radii and bans empty states, wasting tokens and producing generic output. Fix the harness, not the model.
InfoQCutting SDK Duplication in Half with a Rust Core
Temporal's shared Rust core halved SDK duplication, but the bridge layer's complexity is the real lesson for leaders scaling multi-language products.
AI EngineerBetter Agent Tooling Can’t Hide Near‑Zero Success on Real Tasks
Background computer‑use agents gain a cross‑platform driver that lifts success rates, but new benchmarks expose a gap on real‑world tasks.
The Pragmatic EngineerDark AI Factories Break: Context Engineering and Slow Loops Work
Dex Horthy explains why his lights-off coding factory failed and how context engineering plus incremental loops are the pragmatic path to reliable AI code.
IBM TechnologyWhen AI Guardrails Lock Out the Good Guys
Open models unshackle attackers but block defenders with guardrails. CISA’s simpler patch-prioritization model may lack teeth.
AI EngineerAI Skills Without Evals Are Production Time Bombs
AI skills boost agents ~15%, but unevaluated skills silently fail and waste tokens. Here's the eval discipline most teams are missing.
AI EngineerHow Cursor’s FDE Team Avoids the Staff Augmentation Trap
Cursor’s FDE lead shares a sharp framework for deciding where high-touch engineering actually drives ROI—and where it’s just expensive staff augmentation.
GOTO ConferencesAI Agents Need Sandboxing, Not Free Rein
Tau5 experiments with AI agents given temporary access to system internals via MCP—but only inside a sandbox. A safe pattern for dev tooling.
