2025年大模型新纪元

2025年，大语言模型进入多模态原生时代，GPT-5和Claude-4代表了当前最高水平。

GPT-5核心能力

1. 超长上下文

from openai import OpenAI

client = OpenAI()

response = client.chat.completions.create(
    model="gpt-5",
    messages=[
        {"role": "system", "content": "你是一个专业分析助手"},
        {"role": "user", "content": "分析这份300页的技术文档..."}
    ],
    max_tokens=4096,
    context_window=200000  # 20万token上下文
)

2. 原生多模态

# 图像理解
response = client.chat.completions.create(
    model="gpt-5-vision",
    messages=[
        {
            "role": "user",
            "content": [
                {"type": "text", "text": "描述这张图片"},
                {"type": "image_url", "image_url": {"url": "data:image/jpeg;base64,..."}}
            ]
        }
    ]
)

# 视频理解
response = client.chat.completions.create(
    model="gpt-5-video",
    messages=[
        {
            "role": "user",
            "content": [
                {"type": "text", "text": "总结这个视频的主要内容"},
                {"type": "video_url", "video_url": {"url": "https://..."}}
            ]
        }
    ]
)

Claude-4核心能力

1. 超强推理

from anthropic import Anthropic

client = Anthropic()

response = client.messages.create(
    model="claude-opus-4",
    max_tokens=4096,
    messages=[
        {"role": "user", "content": "解决这个复杂的数学问题..."}
    ],
    thinking={
        "type": "enabled",
        "budget_tokens": 4000
    }
)

2. Agent能力

response = client.messages.create(
    model="claude-sonnet-4",
    messages=[
        {"role": "user", "content": "帮我完成这个项目..."}
    ],
    tools=[
        {
            "name": "bash",
            "description": "执行shell命令",
            "input_schema": {
                "type": "object",
                "properties": {
                    "command": {"type": "string"}
                }
            }
        },
        {
            "name": "read_file",
            "description": "读取文件",
            "input_schema": {
                "type": "object",
                "properties": {
                    "path": {"type": "string"}
                }
            }
        }
    ]
)
