alt Hacker NewsThe people who switch back and forth between providers every month are a very small, but loud, minority.
OpenAI did pull ahead in limits and quality for a while. Anthropic took it back with the Opus 5.5 rollout. I maintain subscriptions to both providers and use both daily. I can confirm these differences were real, not "it's just vibes and nobody knows anything".
I would bet that 99% of each company's paying customers either did not notice, or did not care enough to consider changing.
The concern for them is if that small group expands. Moving back and forth limits perceived lock in. Someone who moves between oai and Anthropic will also move to e.g. an open source when it’s good enough for their purposes, or will start experimenting and combining. This is how the market will slip through the attempted control.
