OpenAI Chat examples for multimodal input and output, tools, reasoning, structured output, storage, and retries. | Example | Description | | ------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | [Access Memories in Memory Completed Event](/examples/models/openai/chat/access-memories-in-memory-completed-event) | Stream an agent run with stream\_events=True and read user memories off the MemoryUpdateCompleted event, backed by PostgresDb. | | [Chat Agent Flex Tier](/examples/models/openai/chat/agent-flex-tier) | Run o4-mini on the flex service tier by setting service\_tier on OpenAIChat. | | [OpenAI Audio Input Agent](/examples/models/openai/chat/audio-input-agent) | Send a WAV file fetched from a URL to gpt-audio and stream a text answer about it. | | [OpenAI Audio Input And Output Multi Turn](/examples/models/openai/chat/audio-input-and-output-multi-turn) | Send audio input to gpt-audio and carry the conversation across turns with audio replies. | | [OpenAI Audio Input Local File Upload](/examples/models/openai/chat/audio-input-local-file-upload) | Upload a local MP3 file to gpt-audio and get a text description of the audio. | | [OpenAI Audio Output Agent](/examples/models/openai/chat/audio-output-agent) | Get text and audio output from gpt-audio and save each spoken reply to a WAV file. | | [OpenAI Audio Output Stream](/examples/models/openai/chat/audio-output-stream) | Stream pcm16 audio from gpt-audio, printing the transcript while writing frames to a WAV file. | | [Chat Basic](/examples/models/openai/chat/basic) | Run a gpt-4o agent in sync, async, and streaming modes with OpenAIChat. | | [OpenAI Basic Stream Metrics](/examples/models/openai/chat/basic-stream-metrics) | Stream a response, then read run-level and per-message metrics from the last run output. | | [Custom Role Map](/examples/models/openai/chat/custom-role-map) | Point OpenAIChat at Mistral's base\_url and remap the `model` role to `assistant` via role\_map. | | [Chat DB](/examples/models/openai/chat/db) | Store session history in Postgres so a follow-up question can reference the previous answer. | | [OpenAI Generate Images](/examples/models/openai/chat/generate-images) | Legacy DalleTools example that generates an image and reads its URL from the run output. | | [Chat Image Agent](/examples/models/openai/chat/image-agent) | Analyze an image from a URL and search the web for related news, streaming the reply. | | [Chat Image Agent Bytes](/examples/models/openai/chat/image-agent-bytes) | Pass an image as raw bytes and combine vision with web search for current news. | | [Chat Image Agent with Memory](/examples/models/openai/chat/image-agent-with-memory) | Analyze an image with web search, keeping chat history so follow-ups can reference it. | | [Chat Knowledge](/examples/models/openai/chat/knowledge) | Load a PDF into PgVector-backed knowledge and answer questions from its contents. | | [Chat Memory](/examples/models/openai/chat/memory) | Store user memories and session summaries in Postgres and print them after each turn. | | [OpenAI Metrics](/examples/models/openai/chat/metrics) | Print per-message and aggregated run metrics after a YFinance tool call. | | [PDF Input File Upload](/examples/models/openai/chat/pdf-input-file-upload) | Attach a local PDF file to an OpenAI chat agent and ask it to suggest a recipe from the document. | | [Chat PDF Input Local](/examples/models/openai/chat/pdf-input-local) | Attach a local PDF by filepath and query its contents with gpt-4o. | | [Chat PDF Input URL](/examples/models/openai/chat/pdf-input-url) | Attach a PDF by URL and ask the agent for a recipe from the file. | | [Chat Reasoning O3 Mini](/examples/models/openai/chat/reasoning-o3-mini) | Run o3-mini with high reasoning effort and YFinance tools to write a stock report. | | [Retry](/examples/models/openai/chat/retry) | Review retry settings and why invalid model IDs cannot reliably exercise the retry path. | | [Chat Structured Output](/examples/models/openai/chat/structured-output) | Compare JSON mode, strict, and guided structured output for a Pydantic movie schema. | | [Text-to-Speech Agent](/examples/models/openai/chat/text-to-speech-agent) | Generate speech with the OpenAITools speech toolkit and save the returned audio to tmp/speech\_output.mp3. | | [Chat Tool Use](/examples/models/openai/chat/tool-use) | Answer questions with web search tools in sync, streaming, and async modes. | | [Chat Verbosity Control](/examples/models/openai/chat/verbosity-control) | Control response length with the gpt-5 verbosity parameter in a finance report agent. | | [OpenAI With Retries](/examples/models/openai/chat/with-retries) | Review retry settings and why invalid model IDs cannot reliably exercise the retry path. |
