Features -------- [](#features) - Low-level `ChatGPT` client for single Responses API requests - Stateful `GPTConversation` with context management - Bounded multi-round tool execution - PHP callable and manually defined function tools - Hosted web search - JSON Schema responses with local validation - Serializable and resumable conversation sessions - Prompt-cache configuration and usage metrics - Image and custom attachment inputs - Text-to-speech output - Pluggable PSR-18 HTTP transport Requirements and installation ----------------------------- [](#requirements-and-installation) The library requires PHP 8.1 or newer and the extensions listed in `composer.json`. Install the package with `composer require dv-team/openai-chatgpt-api`. Applications must provide an HTTP transport. The bundled `Psr18HttpClient`adapter accepts a PSR-18 client and PSR-17 request and stream factories. Developer documentation ----------------------- [](#developer-documentation) - [Getting started and low-level requests](docs/getting-started.md) - [Conversations, serialization, restoration, and prompt caching](docs/conversations.md) - [Attachments and custom attachment serialization](docs/attachments.md) - [Structured JSON responses](docs/structured-responses.md) - [Tool calling](docs/tool-calling.md) - [Web search](docs/web-search.md) - [Text to speech](docs/text-to-speech.md) - [Models and reasoning](docs/models-and-reasoning.md) - [Executable examples](examples/README.md) All detailed code examples live in `docs/` or `examples/`. The README remains a compact project and documentation index. API overview ------------ [](#api-overview) ### `ChatGPT` [](#chatgpt) `DvTeam\ChatGPT\ChatGPT` is the stateless, low-level client. The caller supplies the complete context for one API request and receives a `ChatResponse`. `ChatGPT` does not retain context or execute requested tools. ### `GPTConversation` [](#gptconversation) `DvTeam\ChatGPT\GPTConversation` owns a conversation context, appends model responses, executes registered PHP tools, and records their results. `step()` performs one API request. `runUntilResponse()` continues through tool rounds until a visible response is produced or its configured step limit is reached. Complete sessions can be persisted with `toArray()` or `toJson()` and restored with `fromArray()` or `fromJson()`. Runtime dependencies and the currently available tools are injected during restoration. Running the executable examples ------------------------------- [](#running-the-executable-examples) Set `OPENAI_API_KEY`, install development dependencies with `composer install`, and follow the commands in [the examples index](examples/README.md). Development ----------- [](#development) Run the unit tests with `composer test`. Run static analysis with `composer run phpstan`. Notes ----- [](#notes) - The library uses the Responses API input format. - JSON Schema responses are validated with `opis/json-schema`. - A custom HTTP adapter must implement `HttpPostInterface` and return an `HttpResponse`. - `ChatResponse::firstChoice()` returns the first response choice. Maintenance ----------- [](#maintenance) Whenever new functionality is added, update both `README.md` and `AGENTS.md` so human-facing and agent-facing documentation stay aligned. ### Health Score 44 — FairBetter than 90% of packages Maintenance94 Actively maintained with recent releases Popularity18 Limited adoption so far Community8 Small or concentrated contributor base Maturity45 Maturing project, gaining track record Bus Factor1 Top contributor holds 98.3% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
