 ## Request-image pricing
 
-An adapter whose provider charges visual tokens for request images declares per-route pricing by overriding `LlmAdapter.imageRequestPricing`, and `ctx.llm.imageRequestPricing(provider, model)` resolves it synchronously for consumers. The token meter resolves the routed model's pricing on every measurement so compaction pressure, retention, and range selection price image history as the routed request actually sends it; the DeepSeek adapter prices each retained occurrence at its per-model pixel-budget projection with the published v4 vision accounting and each occurrence the session's `image/offload` watermark marks offloaded as its placeholder text, while provider usage remains the authoritative anchor for completed requests.
