Discussing GPT 5.6's Instruction Following Performance

The post asks about GPT 5.6's performance on 'instruction following' and 'abstract concept understanding', which the author says are the most important dimensions when building evaluation/agent frameworks.
It also compares GPT 5.5 high and Claude Opus 4.8 high: the former is better for instruction following and implementation, the latter is better at understanding and proactive completion. The author says combining both yields a stronger agent.
