GPT-4.5的成本可能是其前任的20倍，但其對話風格將更具創造力和“自然”

OpenAI於2月27日發布了GPT-4.5的研究預覽，其最先進的AI模型可以識別模式，建立連接並提供創意見解

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和早期的測試人員稱，Chatgpt-M-M-M-M-Openai即將推出的模型的成本可能是其前任的20倍，但其對話風格的創造力和“自然”將會更加有創意和“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.

該公司表示，OpenAI於2月27日發布了GPT-4.5的研究預覽，其最先進的AI模型可以識別模式，建立連接並提供創造性的見解，而無需以優越的方式推理，而沒有以優越的方式進行推理。

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日的聲明中說，Openai表示，GPT-4.5的更廣泛的知識庫和改進的“ EQ”（情緒智力）使其對創造性任務和解決實際問題更有用。

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的增強創造力和更“自然的對話風格”意味著它不太適合執行詳細的分步邏輯 - 至少與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.

該公司表示，這是不權衡的是，它缺乏“經過思考的推理，由於其規模，可能會較慢。”它也不會產生音頻或視頻等多模式輸出。

GPT4.5 is "sometimes worse" at following instructions

GPT4.5在按照說明中“有時更糟”

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和商業新聞通訊首席執行官Dan Shipper的類似評論。

"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.

托運人說：“這不會讓您震驚，但可能會與您成為朋友。”他說，他的公司已經測試了幾天的最新版本。

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

托運人還表示，按照說明，GPT-4.5“有時更糟”。

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研究員Aran Komatsuzaki還說，GPT-4.5的成本比GPT-4O高出約15至20倍以訪問API。 AI Compass通訊的創始人Ashutosh Shrivastava補充說：

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首席執行官Sam Altman承認新的推理模型“不會粉碎基準測試”，並且是“巨大的昂貴型號”。

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

但是其他測試人員在最新模型中強調了一些令人驚訝的優勢。

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，傑克遜實驗室的生物醫學科學家兼教授Derya Unutmaz聲稱，GPT-4.5在醫學圖像診斷中“似乎是顯著的” - 正確地發現了輸卵管異位妊娠。

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教授說，其他AI模型，例如Grok 3，Claude 3.7十四行詩，Gemini 2.0和更早的ChatGpt模型，錯誤地將醫療形象確定為正常懷孕。

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是隨著中國競爭對手High Flyer在一月份推出了開源AI大型模型DeepSeek R1，這與OpenAI型號相比，其成本的一小部分開發。

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

但是，OpenAI的首席執行官Sam Altman聲稱，建立這些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日的帖子中說：“您可以在2023年初的GPT-4到2024年中期的GPT-4O的代幣成本中看到這一點，在那段時間內，每個令牌的價格下降了約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將在幾個月內發布，其中包括多個版本（包括O3）納入一個版本。

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

chatgpt的免費級別將獲得無限制的聊天訪問GPT-5。
