I had the same thought about haiku 3.5. They claimed it was due to the model being more capable, which basically means that they raised the price because they could.

Then there is Poe with its pricing games. Prices at Poe have been going up over time since they were extremely aggressive to gain market share presumably under the assumption that there would be reduced pricing in the future and the reduced pricing for LLMs did not materialize.
