 - Do not add explicit caching or memoization around `process.env` reads or parsed env-var values unless there is a measured hot-path need
 - Exception: in `packages/models`, explicit duplication of model/provider mappings is acceptable and preferred over helper-based expansion. This is the only place in the repo where duplicating model definitions is OK. NEVER add helper functions (e.g. `makeModel(...)`/`makeProvider(...)`) that build model or provider definition objects, even when it means repeating fields across entries — write each model and provider mapping out in full as a plain object literal in the `models` array. Small shared `const` values are fine, but the definition objects themselves must not be constructed by a function.
 - Models and provider mappings in `packages/models` can NEVER be removed, only deactivated. To retire a model or provider mapping, set `deactivatedAt: new Date("YYYY-MM-DD")` (today's date) on the relevant provider mapping(s) instead of deleting the definition. Historical usage records and analytics reference these definitions, so deleting them breaks lookups.
+- In `packages/models`, ALWAYS express per-token prices (`inputPrice`, `outputPrice`, `cachedInputPrice`, and any other per-token price field) using `e-6` notation so the coefficient reads directly as USD per million tokens (e.g. `"1.4e-6"` for $1.40/M — the exact number providers publish). Never use `e-3` or other exponents for per-token prices. This does NOT apply to `requestPrice`, which is a flat USD amount charged per request (e.g. `"0.035"`), nor to `perSecondPrice`.
 - No unnecessary code comments
 - Do not use broad try/catch in API handlers unless to check for specific errors; instead, let errors propagate and be handled by the global error handler
