inputOther was set to raw input_tokens which already includes cache tokens, causing double-counting. Subtract cache_read_input_tokens and cache_creation_input_tokens to get the actual non-cache input count, matching the OpenAI provider's calculation pattern.

In
packages/kosong/src/providers/anthropic.ts,_extractUsageassignedusage.input_tokensdirectly toinputOther. Per the Anthropic API,input_tokensis the total billed input tokens which already includes cache-read and cache-creation tokens. This inflated the reported non-cache input count.Test plan
inputOther + inputCacheRead + inputCacheCreationnow sums correctly toinput_tokens🤖 Generated with Claude Code
