# GPT-4 launched with 8,192 tokens and a limited 32,768-token variant. > Source: > Published: 2026-09-07 12:45:14+00:00 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. NOT BS TOTAL BS TOTAL BS — Verdict: False Verified by Lenz · Sep 7, 2026 The Short Version 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. Caveats The claim conflates the original GPT-4 with the later GPT-4 Turbo model. The 128K context window was announced in November 2023, not March 2023. General references to long-context research do not establish a 128K launch capacity.
