SemiAnalysis: Opus 5.5 gives 5x the subscription value of GPT-6.1 Sol as OpenAI halves $200 plan limits

kimmonismus flags a reversal within weeks: per SemiAnalysis, Anthropic's Opus 5.5 delivers over 5x the API-equivalent value of GPT-6.1 Sol for agentic workloads at the same subscription price — "not even close." On top of that, OpenAI just halved usage limits on its $200 ChatGPT plan, forced to conserve resources despite its compute firepower. Anthropic is the new efficiency champion; a striking turn from the erstwhile aggressor.
