My impression is that none of those systems seems to be efficient. We see time after time systems that solves most 80% of the case to be 90% cheaper. And the way it is, it seems to me that nor openai nor Anthropic can keep the current prices.
Some say that if Anthropic keep delivering improvements and be the first it will make it but for that, you need to disregard all competition from other llm companies and from other competitor systems.
And even though they have the smartest model ever, if someone offers something 90% of it for 90% cheaper it will be worth it.
We already see plenty of companies reducing ai cost because they don't see enough roi
