Anthropic's 5.5 lineup dissected: only Opus 5.5 truly special, Haiku costs 4x tokens

Blogger haider1 argues Anthropic's 5.5 family has made OpenAI look clueless, but the picture varies by model:
- Opus 5.5 is the only one that's truly special and efficient.
- Sonnet 5.5 sees barely any usage.
- Haiku 5.5 beats Luna on benchmarks but uses nearly 4x more tokens per task and costs more per million tokens — winning on scores, losing on economics.
