web_search tool in deepseek harness needs api key from deepseek and deepseek charges you as deepseek-v4-flash usage.

Excerpt

I was experimenting with deepseek harness when found that even if you don't use deepseek models, you can configure the web_search tool with their api key and every hit will cost you as if you called deepseek-v4-flash model. It's a bummer. on top of that there is currently no other free web search plugin available submitted by /u/Motor_Ad16 [link] [comments]
