Hugging FaceGRPO for LLMs: Reward Design Matters More Than Algorithm Choice
GRPO makes RL for LLMs accessible, but reward hacking is a real risk. The key is group variation and careful monitoring—not just watching reward curves go up.
AssemblyAIVoice agents in production: cascading pipelines beat speech-to-speech
Production voice agents rely on cascading pipelines, latency budgets, and context management. Model quality is less critical than cost control and fallback…
Latent SpaceWhy OpenAI’s Productivity Lead Says Bottleneck Is Now Ideas, Not Code
AI democratizes building, but bottlenecks shift to ideas. OpenAI’s productivity lead on what engineering leaders should measure now: at-bats, not commits.
Y CombinatorWhy building a supersonic jet taught me software-like iteration is the key
How a 50-person team built a supersonic jet using software iteration, vertical integration, and early regulatory engagement. The lesson: own your critical…
InfoQRust prevents bugs you didn't know you could eliminate at compile time
Rust's type system prevents more than memory bugs. Learn how ownership, lifetimes, and the type-state pattern eliminate double-use errors, resource leaks…
AI EngineerSilent failures at scale: why your training code probably has undetected bugs
Poolside reveals how broken GPUs and FP8 kernel bugs silently corrupt pretraining. The solution isn't better data—it's training infrastructure that can catch…
AI EngineerEdge AI's dirty secret: DRAM cost, not model quality, is the bottleneck
For consumer robots and IoT, the bottleneck isn't model capability—it's DRAM cost. Google's lead engineer shows why fine-tuning tiny models on synthetic data…
Theo - t3․ggOpus 5: The first practical default model for AI-assisted coding
Opus 5 offers a compelling middle ground between capable and cheap coding. Real savings are 20-25%, not 50%. Teams should test it as a daily driver before…
AI EngineerYour Agent’s Real Benchmark Isn’t Public — It’s Your Production Trace
Turning agent traces into simulations creates a private benchmark that mirrors your tools and policies — the only reliable way to ship agents with confidence.
AI EngineerRelative Scoring and In-Loop Eval Fix AI Video Quality
Character.ai replaced slow, vibe-based video scoring with a fast distilled model that does axis-specific relative comparisons, embedding evaluation in the loop.
