GPT-4 launched with 8,192 tokens and a limited 32,768-token variant.

The Claim

GPT-4 had a context window of 128,000 tokens at its release in March 2023.

The March 2023 release did not provide a 128,000-token context window. OpenAI documented an 8,192-token window for GPT-4 and limited access to a 32,768-token variant; the 128K window was announced for GPT-4 Turbo in November 2023. The claim conflates the original model with that later release.
