## Summary
The Models page is now split into two tabs. **Your models** shows the
models your project has actually used in the selected time range, with
usage charts (cost over time, tokens over time, calls by model), a
per-model table of calls / cost / avg TTFC / avg tokens-per-sec, and
calls/tokens trend sparklines. **Model library** is the full catalog,
reordered from alphabetical to a relevance-based provider order
(Anthropic, OpenAI, Google, then the rest), newest models first within
each provider, with a "New" badge on models released in the last 7 days.
One time-range selector drives the whole Your models tab, so the charts,
the table, and the sparklines all share the same window. Opening a model
shows its own metrics with an independent range picker and a "View in AI
metrics" link that opens the AI metrics dashboard filtered to that
model. The active tab is kept in the URL so it survives a refresh and is
shareable.
## Prompt caching & cost accuracy
Both the Your models tab and the AI metrics dashboard now surface
prompt-cache usage: a cache-savings column plus per-model cached-tokens
and cache-hit-rate views, and a caching section on the dashboard (hit
rate, cached tokens, estimated savings, and hit rate by model).
Building this surfaced a cost bug. `input_tokens` is the total prompt
count and already includes cache-read and cache-creation tokens, but the
cost pipeline charged the full input at the input price and then added a
separate cache line, so cached tokens were billed twice (and on
Anthropic, cache reads were never discounted because their price is
keyed differently). The input price now applies only to the non-cached
remainder, with cache prices resolved across the provider-specific keys,
so LLM cost and the cache hit-rate metric are accurate. Hit rate is
computed as cached reads over total input.
## Notes
Also fixes React "invalid DOM property" console warnings from the
provider icons (the Llama and DeepSeek SVGs used raw `fill-rule` /
`clip-rule` / `clip-path` attributes), which this page surfaces by
rendering more provider icons.
