OpenAI Assistants API
OpenAI's stateful agent platform
Overview
The Assistants API is OpenAI's stateful agent platform — persistent threads, code interpreter, retrieval, function calling. Most production AI assistants from non-AI-native companies are built on this. Per-token pricing plus storage.

ASEAN Perspective
OpenAI Assistants API in Southeast Asia
ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
The Assistants API was OpenAI's stateful agent framework, giving developers managed threads, tool use, code interpreter and file retrieval without building their own orchestration. It was capable and well-integrated with OpenAI's models, and many production assistants were built on it.
The overriding caveat is that it is deprecated: OpenAI announced its sunset for 26 August 2026 and is steering developers to the newer Responses + Conversations APIs, which is a full architectural migration, not a drop-in swap. New projects should NOT build on Assistants today. We score it low on forward-looking value purely because of the end-of-life status; the docs and SDKs themselves remain excellent. Global service, no SEA-specific provisions.
