fix: correct cache hit rate calculation and improve display format#776
Conversation
The cache hit rate formula was double-counting cached tokens because inputTokens (from AI SDK's prompt_tokens) already includes cached tokens. The old formula `cached / (input + cached)` produced ~47% when the actual rate was ~88%. Also restructures the token display from: Tokens: In 525.1k · Out 5.1k · Cache 461.3k/46.77% To: Tokens: In 525.1k (Cached 461.3K, Cache Hit 87.85%) · Out 5.1k Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
