OpenAI releases GPT-4, the first multimodal large language model

Capability Breakthrough

事件摘要

On March 14, 2023, OpenAI released GPT-4 — a multimodal model that could accept both text and image inputs while generating text outputs. GPT-4 scored in the 90th percentile on the bar exam, the 99th percentile on the SAT, and demonstrated dramatically improved reasoning, factuality, and steerability over GPT-3.5. It was integrated into ChatGPT Plus as a premium tier, and its API became the default for developers building on LLMs. GPT-4 raised the bar on what LLMs could do and set a new baseline for AI capability that persisted until the model release wave of late 2024.

影响评估

  • Capability Leap +2 · Long-term

    Achieved professional-level performance on standardised exams (90th percentile bar exam, 99th percentile SAT Math). Introduced multimodal input (vision + text) at scale. Demonstrated significant reductions in hallucination and improved instruction-following compared to GPT-3.5.

    Affected Groups: AI researchers, developers, professionals, students

  • Economic Disruption +2 · Medium-term

    Accelerated AI integration across professional services (law, accounting, consulting, software). ChatGPT Plus ($20/month with GPT-4) became the fastest-growing consumer subscription product. Triggered a wave of enterprise AI adoption across Fortune 500 companies.

    Affected Groups: tech industry, professional services, enterprises, investors

  • Risk Creation -2 · Medium-term

    Raised the stakes on AI safety, alignment, and regulation. GPT-4's improved capabilities (including vision) expanded the surface area for misuse — generating convincing fake documents, detailed instructions for harmful activities, and automated disinformation at scale. Accelerated regulatory efforts including the EU AI Act.

    Affected Groups: policymakers, ethicists, general public, AI safety researchers

OpenAI says GPT-2 is 'too dangerous to release' — the first mainstream AI safety debate goes global

On February 14, 2019, OpenAI announced GPT-2, a language model capable of generating remarkably coherent text. But instead of releasing it fully, OpenAI withheld the complete model, citing 'concerns about malicious applications.' The decision sparked an intense global debate: was OpenAI responsibly cautious or grandstanding for attention? The staged rollout — releasing progressively larger versions over months — became a template for AI safety disclosure. It also marked the first time ordinary people heard the argument that AI could be too dangerous to release, permanently changing how the public thought about AI risk.

OpenAI releases GPT-3, proving that scaling language models unlocks emergent capabilities

In June 2020, OpenAI published GPT-3 (Generative Pre-trained Transformer 3), a 175-billion-parameter language model that demonstrated remarkable few-shot learning—the ability to perform novel tasks from just a handful of examples without fine-tuning. GPT-3 could write essays, generate code, translate languages, and answer questions at a quality that often blurred the line between human and machine output. The paper 'Language Models are Few-Shot Learners' (Brown et al.) validated the scaling hypothesis: larger models trained on more data get qualitatively better, not just incrementally better.

OpenAI launches ChatGPT, bringing AI to 100 million users in two months

OpenAI released ChatGPT, a conversational AI product based on GPT-3.5, free to the public on November 30, 2022. It reached 1 million users in 5 days and 100 million in 2 months, becoming the fastest-growing consumer application in history. The launch marked the moment AI became a mainstream conversation—not just for researchers and tech enthusiasts, but for policymakers, teachers, artists, and the general public worldwide.

Meta releases LLaMA, triggering the open-weight LLM revolution

Meta published LLaMA (Large Language Model Meta AI) in February 2023, a set of foundation language models from 7B to 65B parameters trained on publicly available data only. LLaMA-13B outperformed GPT-3 (175B) on most benchmarks, proving that smaller, well-trained models could rival much larger ones. Although originally released under a non-commercial research license, the weights were leaked and quickly fine-tuned by the community — spawning the open-weight LLM ecosystem that reshaped the AI industry.

Auto-GPT goes viral, giving mainstream developers their first taste of autonomous AI agents

Released on March 30, 2023 by developer Toran Bruce Richards, Auto-GPT was an open-source autonomous AI agent that could break down goals into sub-tasks and execute them using tools like web browsing and file management. It went viral on GitHub, becoming the first widely accessible demonstration of 'AI agents' — AI systems that act autonomously rather than just generating text. Auto-GPT inspired a wave of agent-building and laid the conceptual groundwork for the agent boom of 2025-2026.

Google releases Gemini 1.5 Pro with a million-token context window

On February 15, 2024, Google released Gemini 1.5 Pro, the first large language model with a 1 million token context window — later expanded to 2 million. This breakthrough allowed the model to process entire codebases, hundred-page documents, and hours of video in a single prompt, achieving a 'needle in a haystack' retrieval accuracy of 99.7% across the full context. It set a new capability frontier that competitors raced to match throughout 2024.

EU approves the world's first comprehensive AI law

On March 13, 2024, the European Parliament approved the EU AI Act, the world's first comprehensive legal framework for artificial intelligence. The Act classifies AI systems by risk level (unacceptable, high, limited, minimal), bans certain uses of AI, and imposes transparency and governance requirements on developers. It entered into force on August 1, 2024, with phased implementation through 2026-2027. The law became the global template for AI regulation, influencing legislation in the US, China, and other jurisdictions.

OpenAI releases GPT-4o, bringing real-time voice conversation with AI to everyone

On May 13, 2024, OpenAI released GPT-4o ('omni'), a natively multimodal model combining text, vision, and audio processing in a single neural network. For the first time, users could have real-time voice conversations with an AI that could express emotion, laugh, pause, and adjust its tone — indistinguishable from human conversation. GPT-4o matched GPT-4 on text benchmarks while dramatically improving voice and vision performance. The model was made free for all ChatGPT users, effectively doubling the available AI capability overnight.

Meta releases Llama 3.1 405B, the first frontier-level open-source AI model

On July 23, 2024, Meta released Llama 3.1 405B — the first open-weight model to match closed-source frontier models like GPT-4 and Claude 3.5 Sonnet on key benchmarks. With 405 billion dense parameters and a 128K token context window, it proved that open-source AI could compete at the highest level. The release reshaped the AI industry by demonstrating that open models could match proprietary ones, accelerating the open-weight ecosystem that would define 2025.

OpenAI releases o1, the first reasoning model that 'thinks before it answers'

On September 12, 2024, OpenAI released o1 (codenamed 'Strawberry'), a large language model trained to spend more time 'thinking' before generating responses — using a chain-of-thought reasoning process internally. o1 scored in the 89th percentile on the International Mathematics Olympiad qualifier and reached PhD-level accuracy on physics, chemistry, and biology benchmarks. It demonstrated that scaling compute at inference time — not just training time — could unlock new capabilities, opening a second axis of AI progress.

OpenAI releases GPT-5, unifying reasoning, multimodality, and task execution in a single system

On August 7, 2025, OpenAI released GPT-5, a unified AI system that combined advanced reasoning, native multimodality, and autonomous task execution — eliminating the need for users to switch between separate models (GPT-4o for chat, o-series for reasoning, DALL-E for images). According to Sam Altman, GPT-5 could 'provide PhD-level expertise' across domains. The release marked the culmination of OpenAI's journey from a single-purpose language model (GPT-3, 2020) to a general-purpose AI system capable of reasoning, creating, and acting.
