GPT-4.5的成本可能是其前任的20倍，但其对话风格将更具创造力和“自然”

OpenAI于2月27日发布了GPT-4.5的研究预览，其最先进的AI模型可以识别模式，建立连接并提供创意见解

ChatGPT-maker OpenAI’s upcoming model could be as much as 20 times more costly than its predecessor but will be far more creative and “natural” in its conversational style, according to OpenAI and early testers.

OpenAI和早期的测试人员称，Chatgpt-M-M-M-M-Openai即将推出的模型的成本可能是其前任的20倍，但其对话风格的创造力和“自然”将会更加有创意和“自然”。

OpenAI released a research preview of GPT-4.5 on Feb. 27, its most advanced AI model, which can recognize patterns, draw connections, and make creative insights without reasoning in a superior way to earlier versions, the company said.

该公司表示，OpenAI于2月27日发布了GPT-4.5的研究预览，其最先进的AI模型可以识别模式，建立连接并提供创造性的见解，而无需以优越的方式推理，而没有以优越的方式进行推理。

OpenAI said GPT-4.5’s broader knowledge base and improved “EQ” (emotional intelligence) make it more useful for creative tasks and solving practical problems, OpenAI said in a Feb. 27 statement.

Openai在2月27日的声明中说，Openai表示，GPT-4.5的更广泛的知识库和改进的“ EQ”（情绪智力）使其对创造性任务和解决实际问题更有用。

GPT-4.5’s enhanced creativity and more “natural conversational style” means it isn’t well-suited to perform detailed step-by-step logic — at least compared to OpenAI’s o-series-models, it added.

GPT-4.5的增强创造力和更“自然的对话风格”意味着它不太适合执行详细的分步逻辑 - 至少与Openai的O-series-Models相比。

The trade-off is that it lacks “chain-of-thought reasoning and can be slower due to its size,” the firm said. It also doesn’t produce multimodal output like audio or video.

该公司表示，这是不权衡的是，它缺乏“经过思考的推理，由于其规模，可能会较慢。”它也不会产生音频或视频等多模式输出。

GPT4.5 is "sometimes worse" at following instructions

GPT4.5在按照说明中“有时更糟”

OpenAI’s latest model received a similar review from Dan Shipper, CEO of AI and the business newsletter Every.

Openai的最新模型收到了AI和商业新闻通讯首席执行官Dan Shipper的类似评论。

"It's not going to blow your mind, but it might befriend you," Shipper said, who said his firm has been testing the latest version for a few days.

托运人说：“这不会让您震惊，但可能会与您成为朋友。”他说，他的公司已经测试了几天的最新版本。

Shipper also said that GPT-4.5 is "sometimes worse" at following instructions.

托运人还表示，按照说明，GPT-4.5“有时更糟”。

AI researcher Aran Komatsuzaki also said that GPT-4.5 costs around 15 to 20 times more than GPT-4o to access the API. Ashutosh Shrivastava, founder of the AI Compass newsletter, added:

AI研究员Aran Komatsuzaki还说，GPT-4.5的成本比GPT-4O高出约15至20倍以访问API。 AI Compass通讯的创始人Ashutosh Shrivastava补充说：

In a Feb. 27 post on X, OpenAI CEO Sam Altman admitted the new reasoning model “won’t crush benchmarks” and is a “giant expensive model.”

在2月27日在X上的帖子中，OpenAI首席执行官Sam Altman承认新的推理模型“不会粉碎基准测试”，并且是“巨大的昂贵型号”。

But other testers highlighted some surprising strengths in the latest model.

但是其他测试人员在最新模型中强调了一些令人惊讶的优势。

For instance, biomedical scientist and Professor Derya Unutmaz of The Jackson Laboratory, claimed that GPT-4.5 "appears to be remarkable" in medical image diagnosis — correctly spotting a tubal ectopic pregnancy.

例如，杰克逊实验室的生物医学科学家兼教授Derya Unutmaz声称，GPT-4.5在医学图像诊断中“似乎是显着的” - 正确地发现了输卵管异位妊娠。

Other AI models, such as Grok 3, Claude 3.7 Sonnet, Gemini 2.0 and earlier ChatGPT models, mistakenly identified a medical image as a normal pregnancy, Prof. Unutmaz said.

Unutmaz教授说，其他AI模型，例如Grok 3，Claude 3.7十四行诗，Gemini 2.0和更早的ChatGpt模型，错误地将医疗形象确定为正常怀孕。

OpenAI's latest iteration of ChatGPT comes as Chinese-based competitor High Flyer launched the open-source AI large-language model DeepSeek R1 in January, which was developed at a fraction of the cost compared to OpenAI's models.

Openai的最新迭代Chatgpt是随着中国竞争对手High Flyer在一月份推出了开源AI大型模型DeepSeek R1，这与OpenAI型号相比，其成本的一小部分开发。

OpenAI's CEO Sam Altman, however, claims the cost to build these AI models is falling tenfold or more each year.

但是，OpenAI的首席执行官Sam Altman声称，建立这些AI模型的成本每年下降十倍或更多。

"You can see this in the token cost from GPT-4 in early 2023 to GPT-4o in mid-2024, where the price per token dropped about 150x in that time period," Altman said in a Feb. 10 post.

Altman在2月10日的帖子中说：“您可以在2023年初的GPT-4到2024年中期的GPT-4O的代币成本中看到这一点，在那段时间内，每个令牌的价格下降了约150倍。”

On Feb. 12, Altman said GPT-5 would be released in a matter of months, which will integrate multiple versions —including o3 — into one, OpenAI said on Feb. 13.

Openai在2月13日表示，2月12日，Altman表示，GPT-5将在几个月内发布，其中包括多个版本（包括O3）纳入一个版本。

The free tier of ChatGPT will get unlimited chat access to GPT-5.

chatgpt的免费级别将获得无限制的聊天访问GPT-5。
