3 verifications about GPT-4 GPT-4 ×
“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.
“OpenAI released GPT-4 in March 2023.”
Reliable primary documentation and independent news reporting confirm that OpenAI released GPT-4 in March 2023. Most sources identify March 14 as the announcement and initial rollout date; reporting dated March 15 reflects publication timing or the continuing rollout, not a substantive contradiction.
“OpenAI released GPT-4 on March 14, 2023.”
Contemporaneous evidence confirms that OpenAI released GPT-4 on March 14, 2023. OpenAI’s announcement is independently corroborated by Reuters, Bloomberg, and other major outlets. Access was initially phased, but that does not alter the official release date.
