A professional creative studio puts GPT-6 to the test
OpenAI’s new model impressed us with writing, operating software, and visual design. Anthropic’s Fable still has better instincts for building a product.
Our tests show where it replaces Fable and Opus—and where we’re keeping the alternatives
Anthropic’s latest Opus can do impressive work—but getting it there may require dismantling the systems you already use
Sol is fast, resourceful, and unusually easy to steer—but Fable still gets the assignments we want to hand off completely
Anthropic’s new model can draft, code, and analyze competently, but every use case has a cheaper, faster, or smarter alternative
The Mythos-class model is a warp drive for power users—but overpowered for everyone else
Opus 4.8 tops both our Senior Engineer benchmark and our writing tests. It’s the most complete model we’ve tested. We just wish it had an app to match.
OpenAI’s new model is a top-end senior engineer—and easy to talk to
Anthropic's latest Opus is more precise, more literal, and the best coding model we've tested on well-specified tasks—but it won't fill in the gaps for you anymore
The AI-native IDE is now becoming an agent-orchestration tool. Will it work?
GPT-5.4 is fast, opinionated, and good enough to tempt our Opus loyalist
Sonnet 4.6 delivers Opus-close performance at half the price—but speed didn't come along for the ride
We’ve tested both models thoroughly—here’s our head-to-head Vibe Check
It one-shotted a problem other models missed—and brings agentic, parallel work to non-coding tasks
The autonomy we wanted is here—but the model still does what you say, not what you mean
OpenAI nailed the interface. But it's built for hardcore engineering.
The asynchronous, agentic workflow developers love is finally accessible to everyone—but the polish isn't there yet
OpenAI's latest model update excels at instruction-following and extended tasks, but don't expect it to surprise you
Switching browsers is a pain. Here are the ones that our team deemed worth it.
