Install the AI Packages

This is the step people skip, and skipping it is the single most common reason a correctly configured store generates 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 and then shows a "required packages are missing" warning in its configuration section.

Install them

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

The admin shows this exact command, with a Copy button, when any package is missing.

What each package is for

Package	Needed for
`symfony/ai-agent`	The agent that issues the generation call. Always required.
`symfony/ai-platform`	The shared platform layer. Always required.
`symfony/ai-open-ai-platform`	ChatGPT (OpenAI)
`symfony/ai-gemini-platform`	Google Gemini
`symfony/ai-anthropic-platform`	Anthropic Claude
`symfony/ai-mistral-platform`	Mistral AI
`symfony/ai-ollama-platform`	Ollama
`symfony/ai-open-router-platform`	OpenRouter
`symfony/ai-generic-platform`	Generic OpenAI-compatible bridge. Part of the required set.
`symfony/ai-cerebras-platform`	Cerebras
`symfony/ai-cohere-platform`	Cohere
`symfony/ai-deep-seek-platform`	DeepSeek

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, and the configuration fields stay hidden.

Pin to ^0.7

The module is written against the 0.7 API. A different 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

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

Next: Enable & Compile.
