OpenAI DevDay — Custom GPTs, GPT Store, and GPT-4 Turbo
At its first developer conference, OpenAI announced custom GPTs — user-configurable AI assistants with custom instructions, knowledge files, and tool access — along with a GPT Store for sharing and discovering them. OpenAI also unveiled GPT-4 Turbo with a 128,000-token context window and significantly lower API pricing compared to the original GPT-4. The Assistants API with code execution and file retrieval was launched simultaneously.
Why it mattersCustom GPTs and the Assistants API gave developers a no-code path to productize AI workflows with file retrieval and code execution, dramatically lowering deployment friction.
Try itIn retrospect, the pattern to notice is that GPT-4 Turbo's 128K context at lower cost made retrieval-augmented generation optional for many use cases where context could fit the full document.
