Since openai removed access to 4.5, I am looking for something comparable from any other company.
Personally, I used it when 4o was not good enough. 4.5 was way better at research and doing more complex programming tasks.
What is comparably good in your experience?


Yea, the best way to know is to input things you would really try
Recently discovered https://lmarena.ai/ and sometimes I try a prompt that isn’t personal or sensitive, and check how the different models do. Allows me to find the best (or less bad) one
