It's a very low baseline with Siri, so almost anything would be an improvement.
Ollama! Why didn’t they just run Ollama and a public model! They’ve kept the last 10 years with a Siri who doesn’t know any contact named Chronometer only to require the best in class LLM?
The point is that once Siri is switched to a Gemini-based model, the baseline presumably won't be low anymore.
