Per million tokens: input, output, cache write, cache read. Thinking tokens bill as output. Agent-made runs use the same table
Agent-made runs marked est.: The Agent tool reports only its final context size, and every tool step re-reads that cached context, so a session is estimated from its steps: cache read = steps × 0.6 × context, cache write = context × 1.5, input = steps × 1,500, output = steps × 350
