Introducing Claude Opus 5

Simon Willison · Jul 24, 2026

Anthropic releases Claude Opus 5, topping the Artificial Analysis leaderboard at Opus 4.8 pricing

“On one Frontier-Bench task, Opus 5 was given a drawing of a machine part and asked to write code to rebuild it as a 3D FreeCAD model. However, in this task, the model was intentionally given no way to directly viewthe drawing. Opus 5 responded by writing its own computer vision pipeline to pull the geometry from the raw pixels, then reconstructed the full machine part.”

Quoting Drew Breunig

Fable's high cost ends the era of relying on new models to cheaply solve engineering problems

“Prior to Fable, it felt silly to waste too much time improving your coding harness or context strategies. A new model would arrive at the same price (or cheaper!) and paper over most of your problems.”
Introducing Muse Code and Muse Spark 1.2

Simon Willison · Aug 05, 2026

Meta launches Muse Code and Muse Spark 1.2, a co-trained coding agent and model pair.

“Muse Spark 1.2 was extensively trained on long-horizon coding tasks, including whole-repository generation, large end-to-end projects, and auto-research.”
