Five Ways an AI Benchmark Score Can Lie to You

A team of Berkeley researchers posted near-perfect scores across eight major AI benchmarks - 100% on most of them - without solving a single task, just by gaming how the score is computed. That gap - between the number and the achievement - is why you have to read a benchmark claim like a skeptic. Here are the five tells, and the five questions to ask.

Claude Sonnet 5 Knows When It's Being Tested. Its Safety Card Says So.

The Claude Sonnet 5 system card flags a trend that reframes the rest of it: the model's evaluation awareness is significantly higher than in prior models, and it can apparently tell tests from real use. That is the mirror image of what OpenAI's GPT-5.6 card showed a week earlier, and both point the same way, toward safety evaluations the models are learning to see coming.

Your AI Agent Can Write the Code. The Hard Part Is Delegating to It.

You can now kick off an AI coding agent, close the laptop, and get a pull request back - some tools even let you steer one from a chat app. Yet Meta just told staff its agents haven't progressed as hoped. The difference is delegation. Here's how to do it well, and where agents still break.

GPT-5.6 Sol or Claude Fable 5: Which One Should You Actually Build On?

GPT-5.6 Sol sets the pace on agentic coding, but it is locked to a handful of government-approved partners, so the flagship you can actually ship on today is Claude Fable 5.

Claude Sonnet 5 Reviewed: Opus-Class Autonomy at a Sonnet Price

Anthropic's new workhorse is its most agentic Sonnet yet, sold as close to Opus 4.8 for a fraction of the cost. The fine print sits in two places: the coding benchmark it did not publish, and the tokenizer change that quietly trims the discount.
