Question
An analysis of my spent is showing that it is going to the roof. Below my tokens which is just going wild. I changed from Opus 4.6 to Opus 4.7 for most of my work on Jun 6.

I asked Cortex Code to analyze why this happens:
No, caching is NOT being applied to your REST API calls.
Here's the evidence:
Service | cache_read_input | cache_write_input | Caching Active?
-- | -- | -- | --
REST API (your calls) | NULL | NULL | No
Cortex Code Snowsight | 271,527+ per request | 8,123+ per request | Yes>
What This Means
- Your REST API calls show only
input and output in TOKENS_GRANULAR — no cache_read_input or cache_write_input fields at all. - By contrast, your Cortex Code Snowsight usage (this session) shows 96%+ cache hit rates (
cache_read_input dominates input), meaning prompt caching is heavily utilized there.
Cost Impact
Prompt caching on Anthropic models typically gives 90% discount on cached input tokens. Your REST API calls average ~300K input tokens per request with zero caching. If even 70% of those tokens were cacheable (common for repeated system prompts, tool definitions, or conversation history):
- Current: ~300K input tokens billed at full rate per request
- With caching: ~90K at full rate + ~210K at 10% rate = effective ~111K tokens
- Potential savings: ~63% on input token costs → roughly ~$4,000/month in savings at current volume
