Recently shipped native document input and image search for the Agent API.

**The Agent API now reads documents and images.**
- Native document input takes PDF, DOC, DOCX, TXT, and RTF as `input_file` content, inline or from a public HTTPS URL. Multi-turn conversations continue with `previous_response_id` without re-uploading inline documents.
- `image_search` returns typed `image_search_results` with image and source-page URLs, plus result limits and domain, format, and safe-search filters. It costs $2.50 per 1,000 successful invocations.

**Search presets got cheaper and faster.** The `low`, `medium`, and `high` presets now use Fast Search for `web_search`, cutting cost from $2.50 to $1.00 per 1,000 invocations and saving roughly 800 ms. `xhigh` is unchanged.

**Sandbox extraction now reports what it costs.** Token usage and cost for successful `pplx_sdk.llm.extract` calls show up in `usage.tool_calls_details.sandbox` and roll into `usage.cost.total_cost`, priced with `openai/gpt-6-luna`. Historical responses are not backfilled.

**Decisions API switched its default model.** `pplx-decider-v1.1-27b` replaces `pplx-decider-v1-27b`, with input at $0.02 per million tokens, down from $0.04. The old name still works at the same rate. Claude Haiku 5.5 (`anthropic/claude-haiku-5-5`) also joined the Agent API; requests over 100k input tokens use higher rates.
