GT DeepSeek for AI

GT DeepSeek for AI is an independent DeepSeek provider for the native WordPress AI Client in WordPress 7.0+. It registers the isolated provider ID gt-deepseek, so it can run beside another connector registered as deepseek during migration.

The plugin supports DeepSeek text generation, reasoning, tools, structured output, server-side web search, and seven WordPress editorial abilities. It does not advertise capabilities the DeepSeek API does not provide.

Feature coverage

The V4 Flash adapter combines reasoning, final text, and function calls into one WordPress AI Client candidate. This keeps toText() correct while preserving reasoning in the thought channel. Search citations and search actions remain available in the result's additional data.

Honest image ALT text

DeepSeek cannot inspect image pixels. The gt-deepseek/generate-alt-text ability writes ALT text only from textual evidence WordPress already has:

• attachment filename, title, caption, and description
• existing ALT text
• parent post title, excerpt, and body context
• optional context supplied by the editor

Every evidence value is treated as untrusted data. The ability returns vision_based: false, a confidence level, the evidence labels used, and a warning. With save: true, it updates _wp_attachment_image_alt only when the result is non-empty and confidence is medium or high. Weak, conflicting, or decorative-image context produces an empty ALT value.

Included abilities

• gt-deepseek/stop-slop-scan
• gt-deepseek/rewrite-for-voice
• gt-deepseek/suggest-internal-links
• gt-deepseek/generate-faqs-accordion
• gt-deepseek/generate-alt-text
• gt-deepseek/research-with-web-search
• gt-deepseek/rankmath-meta-sync

Abilities that read or modify stored content check the current user's permission for the exact post or attachment.

Requirements

• WordPress 7.0 or later with the WordPress AI Client
• PHP 7.4 or later
• A DeepSeek API key

ACF Blocks and Rank Math are optional. The related abilities report their integration state or return portable output when those plugins are unavailable.

Installation

GitHub release

1. Download gt-deepseek-for-ai-<version>.zip from GitHub Releases.
2. In WordPress, open Plugins → Add Plugin → Upload Plugin.
3. Upload the release ZIP and activate it.

The source and release ZIP are public under the GPL. Manual GitHub installs do not require a product license, but they must be updated manually.

Free checkout with protected updates

Complete the free FluentCart checkout to receive the same plugin plus a lifetime license key for protected WordPress updates. Enter that key under Settings → GT DeepSeek → License and updates.

The FluentCart license controls update delivery only. It does not change the GPL license and is separate from your DeepSeek API key.

Configuration

1. Open Settings → Connectors and add the key for GT DeepSeek.
2. Open Settings → GT DeepSeek to choose default models and reasoning behavior.

The connector uses the WordPress-managed option connectors_ai_gt_deepseek_api_key. For managed deployments, GT_DEEPSEEK_API_KEY can be supplied as an environment variable or constant. GT_DEEPSEEK_BASE_URL can override the API base URL.

Defaults:

• text: deepseek-v4-pro
• structured output and web search: deepseek-v4-flash
• base URL: https://api.deepseek.com/v1

Development

composer install
composer lint
composer phpcs
node --check assets/editor-sidebar.js
./bin/build-zip.sh

bin/build-zip.sh produces a reproducible package in dist/. Runtime changes should be tested by installing that ZIP, not the source directory, into a disposable WordPress site.
