如何在 DALL-E 3 的圖片上增加文字

根據 OpenAI 官方部落格的說明, DALL-E 目前仍然不擅長在圖片上生成文字:

您可能會想要指示 DALL·E 在圖像中生成文本,方法是給它“藍天白雲和天空書寫中的“你好”一詞”之類的指令。

然而,這不是創建文本的可靠或有效的方法。DALL·E 目前的設計目的不是生成文本,而是根據您的關鍵字或短語生成逼真且藝術的圖像。目前,它對書寫、標籤或任何其他常見文本沒有具體的理解,並且經常產生扭曲或難以理解的結果。

據筆者實際嘗試的結果,目前其他主流的 AI 生成繪圖平台如 MidJourney 、 Stable Diffusion 同樣也不擅長在圖片上生成文字。但相對於其他平台, DALL-E 3 借助於 ChatGPT 對於文字的理解能力,在某種程度上更容易生成文字。

實際操作技巧

方法:在 prompt 中加入 [ 你想要的文字 ],並加入明確的指示詞如 write 、 text 、 on 等等讓 DALL-E 3 知道你是要它把 [ ] 中的內容視作文字。請注意,盡量使用簡單的單字,避免採用過長的文字,且這個方法生成的圖片會有一定的失敗率,不是每張圖都可以順利顯現你想要的文字。若剛開始無法產生滿意的結果,請按下 Reload 按鈕多次嘗試。

The image should be in a 16:9 format, emphasizing the vibrant and lively environment.

第一次輸出的二張圖片中,第一張圖片正確地顯示” LEGGIE “這個單字,而第二張圖片多了一個i。

這時我們發現兩個狀況:

  1. GPT-4V 會把我們輸入的 [ ] 轉變成 ‘ ‘ 再提供給 DALL-E 3 作圖。
  2. 我們指定的文字正確,但是圖片中未指定的文字幾乎都是錯的。

第一個狀況其實筆者認為是 GPT-4V 與 DALL-E 3 溝通時的轉譯。筆者實際比較 [ ] 與 ‘ ‘ 指定輸出文字的結果,認為使用 [ ] 還是比較容易讓 DALL-E 3 聽話,正確率相對會高很多。

第二個狀況則暫時無解,在同樣的情景下只能讓 DALL-E 3 跑出相對其他文字較不明顯的圖,或調整圖片背景的描述。例如修改成這樣的 prompt :

Make an advertising board with [LEGGIE] written on it on a high mountain. Sun, sunshine, seagulls, palm trees. 16:9 format.

輸出

Here are the images featuring the 'LEGGIE' advertising board on a high mountain, surrounded by sunshine, seagulls, and palm trees. Each image is presented in a 16:9 format. Let me know if you need any further adjustments!

prompt: An advertising board with the word ‘LEGGIE’ prominently displayed, situated on a high mountain. The scene is bathed in sunshine, with a clear blue sky and the sun shining brightly. Around the board, there are a few palm trees swaying gently in the breeze, adding a tropical feel to the mountain landscape. Seagulls are flying in the sky, enhancing the serene and beautiful outdoor setting. The image should be in a 16:9 format, capturing the contrast between the rugged mountain and the serene, sunny atmosphere with palm trees and seagulls.

更換適合的背景會使得文字相對突出,並減少出現錯誤文字的機率。

Sam Altman 重掌 OpenAI 執行長大位

在經歷了一段波折後,Sam Altman 重返 OpenAI,再次擔任執行長一職。這一令人矚目的變動不僅標誌著這家高科技 AI 初創企業內部的巨大轉變,也顯示出這個行業巨頭在管理層面的新戰略。

事件背景:一週動盪的內部爭議

OpenAI 最近的發展充滿戲劇性。僅僅在一周之前,Altman 被驚人地從他共同創立的公司中解僱,這一決定引發了廣泛的關注和討論。在接下來的五天內,經過激烈的討論和說服,這家被認為是美國最有價值的初創企業最終達成了一項原則性協議,決定讓 Altman 回歸。

OpenAI 董事會重組:新面孔,新期望

在這場風波中,OpenAI 的董事會也經歷了重大改革。多名曾因上周的決定而受到嚴厲審查的成員被撤換。新董事會的成員包括前 Salesforce 聯合首席執行官 Bret Taylor、前美國財政部長 Larry Summers,以及 Quora 創始人 Adam D’Angelo。其中,Taylor 將擔任董事會主席。

微軟的參與:重要的策略伙伴

微軟,作為 OpenAI 的重要投資者,對這家公司有著深厚的影響力。微軟已向 OpenAI 投資超過 110 億美元,持有約 49% 的股份。上周 OpenAI 的決定讓微軟感到意外,迅速行動,邀請 Altman 領導該公司的一個新 AI 小組。在先前董事會決定之後,包括 OpenAI 前總裁 Greg Brockman 在內的許多成員選擇辭職,以示抗議。Brockman 也表示將隨 Altman 一同回歸 OpenAI。

Altman 和 Brockman 的聲明:堅定的回歸

對於回歸 OpenAI,Altman 表達了他對這家公司及其使命的深厚愛意。他提到,決定加入微軟是考慮到這對他和團隊是最佳選擇。然而,在新董事會的支持和微軟 CEO Satya Nadella 的鼓勵下,他決定重返 OpenAI,並期待與微軟繼續深化合作夥伴關係。

微軟的回應:承諾與支持

微軟 CEO Satya Nadella 對 OpenAI 董事會的變動表示鼓舞,他認為這是實現更穩定、明智和有效治理的第一步。Nadella 強調,他、Altman 和 Brockman 一致認為,他們將在 OpenAI 的領導下發揮關鍵作用,以確保公司的持續繁榮並實現其使命。微軟將繼續強化與 OpenAI 的合作,將最新一代 AI 技術的價值帶給客戶和合作夥伴。

對 AI 產業的影響:領先地位與影響力

OpenAI 不僅被廣泛認為是當前 AI 競賽的領跑者,而且在不到一年的時間內,也成為了數千家其他初創企業的王牌製造者,這些企業正在 OpenAI 的軟體平台上開發新技術。對 OpenAI 的投資也大幅提升了微軟在 AI 方面的努力,幫助它吸引了許多企業,並增強了華爾街對微軟未來的積極展望。

投資者觀點:對未來的樂觀期待

OpenAI 的支持者,如 Thrive Capital 創始人 Joshua Kushner,對 Altman 回歸表示樂觀。Kushner 強調,Altman 和 Brockman 對公司的完整性擁有深厚的承諾,且在激勵和領導方面無人能及。他表示,這對 OpenAI 的創始人和他們所建立的公司來說是一個非常令人興奮的回歸。

結論:全方位的積極展望

這次事件的結局對 OpenAI、其員工、依賴其技術的合作夥伴,以及整個世界都是一個最佳的結果。這不僅顯示了 OpenAI 團隊在過去幾天所展現的韌性和力量,也為這家公司和其合作夥伴在未來的合作鋪平了道路。

Google 搜尋團隊 : SEO 應重視基本技術問題與高品質內容

Google Search 關係團隊三位資深成員 Martin Splitt、Gary Illyes 以及 John Mueller 在 Search Off the Record 這個播客節目中,針對 SEO 從業人員提供了許多實戰經驗和看法。其中最值得關注的,是他們強烈主張 SEO 不該流於形式,而要專注在解決基本技術問題以及創造高品質內容上。

技術 SEO 的基礎工作

技術 SEO 確保搜尋引擎可以順利抓取和理解網站上的資訊。Gary Illyes 提到,很多大型網站的 SEO 卻時常忽略一些最基本的技術要求,例如網站的可抓取性,如果 Googlebot 連接不上網站或者渲染頁面失敗,那就無從談起 SEO 了。此外,適當配置網站結構和 URL 是讓搜尋引擎正確索引內容的必要條件。如果忽視了這些基礎工作,那麼再多的流量和關鍵詞優化也毫無意義。

重視內容品質和用戶體驗

Martin Splitt 指出,許多 SEO 過分強調流量數字,但真正重要的是用戶的轉化率或商業利潤。Gary Illyes 則認為,優質內容應該要能幫助用戶解決問題並達成目標。內容本身的價值高低,才是網站可持續發展的關鍵。

John Mueller 也提到了網站除彈性之外,還需要定期評估內容的品質和必要性。刪除或合併過時內容,使資訊更加集中和易於查找。

評估內容品質的方式

要評估內容對用戶的價值,關鍵在於分析相關查詢的表現,以及用戶在特定內容上花費的時間。如果用戶只點閱一瞬間就離開,那麼這類內容就必須重新審視和優化。最直接的方法是檢視用戶評論,看看他們對某些內容是否感到滿意和有幫助。

結語

要實現 SEO 的長期穩定成效,技術基礎和內容品質都是不可或缺的。SEO 從業人員要牢記為用戶服務的初衷,在優化過程中關注用戶的真實需求和感受,這樣才能建立起可持續發展的數字資產。
