AI EngineerGraph Design Cut AI Tool Calls 40% in Code Search
A 40% drop in AI code-search tool calls wasn't from better models—it came from graph algorithms. But only if you build the graph right.
AI EngineerAI Model Quality Is Table Stakes—UX Now Decides Adoption
Many AI features fail because users don't trust them. This talk breaks down the UX patterns—citations, transparency, control—that can make or break adoption.
Theo - t3․ggFable 5 vs GPT-5.6: The Real Cost Is Merge Debt
Two top AI coding models, two opposite tradeoffs: cost vs merge quality. Fable 5 is the premium plan, Soul the fast executor. Here's when to use each.
AI EngineerLoops Won’t Replace Your Engineers—Unless You Let Them
Loops promise speed but demand discipline: verification gaps, cost, and code rot threaten to undercut the hype. Pragmatic teams start small.
David OndrejManaging AI Agents, Not Just Using Them
An AI engineer uses an agent manager and adversarial code review catching 63% of AI-generated changes—a shift in how teams should design AI workflows.
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.
