## Overview

**gpt-4-0314** is the launch snapshot of [GPT-4](/families/gpt-4), released by [OpenAI](/openai) on Mar 14, 2023 — the [system card](https://cdn.openai.com/papers/gpt-4-system-card.pdf)'s "GPT-4-launch," i.e. [GPT-4-early](/models/gpt-4-early) plus the safety-focused RLHF pass. It shipped to ChatGPT Plus subscribers and a waitlisted API on day one; Microsoft simultaneously confirmed [Bing Chat](/models/bing) had been running a GPT-4 lineage model since February.[^announcement]

Launch claims centered on professional-exam performance — most famously a simulated bar exam score "around the top 10% of test takers" against GPT-3.5's bottom 10%.[^announcement] (Eric Martínez's later re-analysis put it "below the 69th percentile" against July test-takers, and around the 48th on the essay portion — the top-10% framing held only against February repeat-takers.[^barexam]) Context length was 8,192 tokens, with a `gpt-4-32k` variant. GPT-4 was announced as multimodal, but at launch "image inputs [were] still a research preview"[^announcement] and stayed so until GPT-4V arrived in ChatGPT in late September 2023[^gpt4v] — as deployed, 0314 was text-only.

The launch also marked a turn in AI discourse: OpenAI published no architecture, parameter-count, or training-data details, citing "the competitive landscape and the safety implications of large-scale models,"[^report] and within two weeks the Future of Life Institute's open letter called for a pause on training systems "more powerful than GPT-4."[^pause]

## Lifecycle

- Superseded in the API by [gpt-4-0613](/models/gpt-4-0613) on Jun 13, 2023; `gpt-4` requests pointed at the newer snapshot thereafter.
- The ChatGPT product clock ran separately: "GPT-4" left ChatGPT on Apr 30, 2025, fully replaced by GPT-4o (by then it was serving 0613-lineage weights),[^retire] while 0314 stayed reachable in the API until its retirement in March 2026.
