I’m significantly older than you. I started coding in the late 60s. My current strategy is to not read any of the code written by my agents. That’s the only way I can take advantage of their productivity. What I do instead is to surround the agents with extreme constraints. Unit tests, gherkin tests, QA procedures, quality metrics, mutation testing, test coverage, and a plethora of others. In the end, I have very high confidence in the code they produce because they’ve had to run the gauntlet of all of my constraints and tests.
A few patterns we frequently use with Fable 5:
Use Fable 5 as an "advisor."
An executor (Sonnet 5) calls Fable 5 for guidance.
Most tokens are billed at the lower executor rate.
I've heard a lot of questions about Fable's availability on subscription plans.
While it will come off subscriptions after July 7th, we aim to restore Fable as a standard part of our subscriptions as soon as capacity allows, as we mentioned in our original blog post.
🇯🇵 A Cruel End for Japan’s Warrior Captain
Some footballers leave their mark with tricks, headlines and highlight reels. Wataru Endo left his with honesty, courage and an unfashionable devotion to the team.
The moment he limped out of Liverpool's season at Sunderland, the fear was immediate. You watched a player who would willingly put himself in harm's way for the cause, and you wondered whether the price had finally become too high. Sadly, it has.
There's something particularly cruel about a captain being denied his final World Cup. Endo had earned that stage. He'd earned the armband. He'd earned the chance to lead his country one last time before passing the torch.
The reaction from supporters tells its own story. Not of a global superstar, but of a footballer held in genuine affection wherever he has played. People speak of a warrior, a professional, a man of character. Those aren't empty compliments. They're the tributes reserved for players who make others better, who carry responsibility without complaint and who never ask for applause.
Football increasingly celebrates the spectacular. Endo belongs to an older tradition. He wins duels, covers ground, protects teammates and accepts the hard work that allows others to shine. Every successful side needs players of his kind, even if they rarely occupy the headlines or match reports.
Japan will miss him. The game will miss him too.
A fine footballer, a respected captain and, by all accounts, a thoroughly decent man. His is a career worth saluting.
