Is Open Claude Free?

Upon using the command /cost, it says some amount like below.

Total cost: $66.07 (costs may be inaccurate due to the usage of unknown models)

Any idea on this, please

its free but you still need to pay for models you need to use

I am using models from nvidia build, specifically "https://build.nvidia.com/openai/gpt-oss-120b", which is free, could you please advice on this as well, if this would cost me any dollar? @kevincodex1

Hello. Did you try Xiaomi MiMo and are you happy with this model. Do you recommend it and can you compare it with Claude and Codex v5.4 or v5.5?
