> Didn’t Sol-6.1 top Astra?

On specific coding skewed benchmarks yes.

But Astra is in a different league when it comes to doing research and investigative tasks that require exploration.

For my usecases, Astra is pareto frontier - it dominates Fable 5.1 on cost. Fable 5.1 is a phenomenal model but Astra is cheaper and uses way less tokens and steps to produce similar output.
