OpenAI API
The OpenAI API is an application programming interface service provided by OpenAI that allows developers to invoke its large language models (such as the GPT series) and related AI capabilities through standardized HTTP requests, including text generation, conversation, image generation, and embedding vectors. Its interface specification has been widely adopted and referenced by many third-party AI services, establishing it as an important reference standard for AI model integration.
Core Facts
@ai-sdk/togetherai is the official Vercel AI SDK adapter for the TogetherAI platform, built on top of the openai-compatible base package.
@ai-sdk/zai depends on @ai-sdk/openai-compatible, indicating that Zhipu GLM's API interface is largely compatible with OpenAI's calling conventions.
llama-server is a local HTTP inference service provided by llama.cpp that implements an interface specification highly compatible with the OpenAI Chat Completions API.
Timeline (last 90 days)
Kimi K3.1 Pro can be accessed through an OpenAI-compatible endpoint without changing the SDK.
Telnyx AI Gateway's architecture divides the system into a management plane, an inference plane, and an observation plane; the management plane uses account API keys to manage token groups, token keys, budgets, and usage reports, while the inference plane is OpenAI API compatible and uses only token keys.
N.O.V.A. calls models through NVIDIA's OpenAI-compatible API, with keys stored encrypted and never sent to the browser.
The OpenAI API key needs a small amount of prepaid credit; about 500 rupees lasts 6-7 months.
In the OpenAI API, service tiers are usually passed as a request parameter to choose between standard scheduling and higher-priority scheduling.
Multi-turn tool calling in Agents workflows means a single user request may trigger multiple model calls in series, and the network and queueing latency of each hop accumulates.
The ultrafast service tier sits alongside existing tiers such as priority, and developers must explicitly specify it in the request for it to take effect.
Failure to L2-normalize embedding vectors causes bias in pgvector's cosine similarity ranking; after normalization recall@10 improved from 0.68 to 0.91.
The customer app is built on the OpenAI API, with goals of basket building, repeat purchases, and meal suggestions tailored to shopper preferences.
The project's system architecture splits the computer-use agent into three parts: the eyes use AirPlay mirroring to capture the screen, the hands use an ESP32-S3 disguised as a USB mouse and keyboard to send input, and the brain uses an OpenAI-compatible vision-language model to make decisions.

65%VerifiedThe API aggregation layer is typically built on the OpenAI-compatible interface specification, allowing existing tools to connect simply by modifying the endpoint address.
65%VerifiedMainstream APIs from OpenAI, Anthropic, and others all use the SSE protocol to return token streams, with the frontend consuming data via the EventSource API or the fetch ReadableStream interface.
65%VerifiedThe core of the OpenAI-compatible protocol is the /v1/chat/completions REST interface specification, which defines fields such as model, messages, and temperature, as well as the streaming response (Server-Sent Events) format.
65%VerifiedLocalAI is a fully localized AI inference engine compatible with the OpenAI API interface specification.
65%VerifiedEvery Function Call must have a corresponding Function Call Output, and the call_id of both must be exactly identical; otherwise the OpenAI API will reject the request and return an error.
65%VerifiedWhen using a relay station, only the base_url and API key need to be modified, and client programs can seamlessly switch from the official API to the relay station without any code changes.
