Developer Rick Lamers shares his hands-on takes on current coding models, matching others' opinions: Sonnet 5.5 is great but you shouldn't be using it, Opus 5.5 writes super well, Sol 6.1 offers incredible value, while Astra and Fable 5.1 are niche choices usually not worth it.

He also notes an interesting detail: Pi Durable went through 7x rewrites, yet agent session files on disk remain unstandardized.
