# Release history

## 2026-06-22 — Inline video frames

* **Added**: `video_frames` content part for chat completions — pass pre-decoded video frames inline (each with an `image_url` and a `timestamp_ms`) as an alternative to a single `video_url`. Useful when you've already sampled frames client-side or need precise control over which frames the model sees.

## 2026-06-15 — Files API

* **Added**: `/v1/files` endpoints (upload, list, retrieve, retrieve content, delete) for uploading images and video once and referencing them by id across requests.
* **Added**: Files developer guide and OpenAI-compatible API reference pages.

## 2026-06-09 — Detect API

* **Added**: `/v1/detect` endpoint for direct grounded object detection — return boxes or points from text `categories`, annotated `exemplars`, or exhaustive detection, without building a chat-completions prompt.
* **Added**: Detect capability guide and API reference pages with full request/response schemas.

## 2026-05-12 — Perceptron Mk1 launch

* **Added**: `perceptron-mk1` — flagship VLM with image + video input, 32K context, and reasoning support.
* **Added**: Video capability guides (Video Q\&A, Video Clipping, ICL Video) plus matching cookbook notebooks.
* **Added**: Models tab with per-model spec pages (modality, context, pricing).
* **Updated**: Image capability guides rewritten for Perceptron Mk1 and the new SDK API surface.

## 2026-03-31 — Perceptron MCP launch

* **Added**: Tutorials for manufacturing defects, OCR & Layout Extraction, and PDF document intake.
* **Added**: Best practices playbooks for prompting, latency optimization, and security.
* **Added**: API reference navigation with endpoint examples and CLI commands.
