The way I keep describing Fable 5.1 to people is that it just works. I explain what I want in a few vague, messy sentences, and it figures out the rest. It fills in the gaps the way I would have. It's a truly impressive model in so many ways and I hope you enjoy using it! 107.9K views · 1.1K likes · 21 reposts · 95 replies Open on X →

Some of my favorite graphs from Opus 5 launch. We put a ton of work into making this model token efficient across domains while still raising the intelligence bar. It feels very smooth to use and I prefer it over Fable 5 for many coding tasks. https://t.co/bScX0FgtLq 60.3K views · 694 likes · 36 reposts · 53 replies Open on X →
