Hyperagent says Opus 5 is clearer, while GPT-5.6 Sol is leaner and cheaper

Hyperagent's testing suggests flagship models are now judged less by raw capability and more by how they behave in practice.
The post highlights two tradeoffs:
- Opus 5 writes more clearly and does well in browser-based work and evidence-backed decisions, but is cautious and verbose.
- GPT-5.6 Sol is leaner, less verbose, and consistently cheaper.
The takeaway: choose the model that fits the task instead of treating one as universally best.
