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.
AI EngineerUber’s AI Agent Lesson: Redundant QA Gates Stop Reward Hacking
Uber’s photo agent auto-tunes via closed-loop evals, but layered QA gates stop hallucinations and reward hacking before reaching users.
AI EngineerYour Traces Just Got a New Job: Fueling Self-Fixing Code
Arize's Signal turns observability into PRs, so engineers review fixes, not dashboards—needs more telemetry, custom skills, trust.
OpenAIStop Counting Tokens, Start Measuring Outcomes
OpenAi’s ‘value maxing’ reframes AI spend around outcomes, not tokens. GPT-5.6 caching and compaction cut costs 80%+—if you avoid breaking the KV cache.
Y CombinatorYour dev teams are already using a coding agent you haven't approved
Model-agnostic coding agents spread bottom-up: Open Code’s 20x growth shows devs bypass procurement. Enterprises must urgently govern token costs.
AI EngineerStop Code-Chasing Models: Why AI Tasks Need Function-Like Abstraction
DSPy lets teams abstract AI tasks from model implementation, potentially reducing costs and vendor lock-in—but strict interface definitions are mandatory.
AI EngineerThe Real Cost of AI: Why Model Loyalty Is a Trap
AI token economics are broken: providers overcharge and lock you in. Notion’s model-agnostic, open-weight, governance-driven approach offers an exit.
