Install the AI Packages

This is the step people skip, and skipping it is the single most common reason a correctly configured store translates nothing.

Why it is a separate step

The Symfony AI connectors are listed under suggest in the module's composer.json, not under require. Composer never installs suggest entries. So composer require on the module alone leaves you with a module that installs cleanly, loads its admin section, and fails on every translation.

Install them

composer require \
    symfony/ai-agent:^0.7 \
    symfony/ai-platform:^0.7 \
    symfony/ai-gemini-platform:^0.7 \
    symfony/ai-anthropic-platform:^0.7 \
    symfony/ai-open-ai-platform:^0.7 \
    symfony/ai-open-router-platform:^0.7 \
    symfony/ai-ollama-platform:^0.7 \
    symfony/ai-mistral-platform:^0.7 \
    symfony/ai-cerebras-platform:^0.7 \
    symfony/ai-cohere-platform:^0.7 \
    symfony/ai-deep-seek-platform:^0.7

What each package is for

Package	Needed for
`symfony/ai-agent`	The agent that issues the translation call. Always required.
`symfony/ai-platform`	The shared platform layer. Always required.
`symfony/ai-open-ai-platform`	OpenAI
`symfony/ai-gemini-platform`	Gemini
`symfony/ai-anthropic-platform`	Anthropic
`symfony/ai-ollama-platform`	Ollama
`symfony/ai-open-router-platform`	OpenRouter
`symfony/ai-mistral-platform`	Mistral AI
`symfony/ai-cerebras-platform`	Cerebras
`symfony/ai-deep-seek-platform`	DeepSeek
`symfony/ai-cohere-platform`	Cohere

Install all of them

The module checks for every bridge class before reporting the packages as available. Installing only the one provider you plan to use still shows the "missing packages" warning.

Pin to ^0.7

The module is written against the 0.7 API. A newer major version moves or renames the platform bridge classes and the admin reports the packages as missing.

Confirm they are installed

composer show | grep symfony/ai

Eleven packages should be listed, all on a 0.7.x version.

Next: Enable & Compile.
