I’m comparing prices between Claude Haiku and Flash 1.5, which have different price rates and tokenizers for the Thai language.
Clearly, Flash 1.5 has a better tokenizer, converting 512 characters to 199 tokens, while Haiku converts 512 characters to 414 tokens.
Therefore, I’ve concluded that Flash 1.5 is more cost-effective for common chat,
but I would like to know about the extra token cost for function calling.
