Corey: 我认为OpenAI开发者日发布的更新大多是实用且对开发者友好的增量式改进,而非具有突破性的重大改变。实时API允许开发者构建类似ChatGPT应用中的语音到语音对话体验,未来还将支持视频和视觉等更多模态。然而,实时API的高昂成本(约9-18美元/小时)限制了其在应用程序中的广泛应用。我们尝试使用实时API创建了一个收费的"Corey Hotline"来测试其功能,结果显示其语音交互能力出色,但仍然能识别出是AI。与Retell等其他公司提供的语音模型相比,OpenAI的先进语音模式虽然体验更好,但成本更高,在商业应用中缺乏竞争力。OpenAI的实时API最主要的应用场景是创建具有持久记忆和工具调用的智能语音助手,这将极大地提高工作效率。 Chris: OpenAI开发者日发布了很多对开发者友好的实用更新,而非颠覆性的重大突破。实时API允许开发者构建类似ChatGPT应用中的实时语音对话体验,微软的新Copilot也使用了类似的先进语音模式。Retell提供了多种语音功能,包括内置的LLM和WebSocket技术,与OpenAI的实时API类似。Retell克隆的Corey语音在对话中断和保持主题方面表现出色,在保持对话目标和回答问题方面取得了平衡,在成本效益方面更具优势,且应用广泛。OpenAI的先进语音模式虽然体验更好,但其高昂的成本使其在商业应用中缺乏竞争力。OpenAI的实时API存在供应商锁定问题,因为它依赖于GPT-4.0模型,在控制用户体验方面存在局限性,因为它缺乏对模型内部过程的干预能力。未来,结合视觉UI的语音API将提供更丰富的交互体验,但许多用户不需要AI模拟真人,他们更关注任务的完成效率。 Corey: OpenAI的提示缓存功能可以自动缓存提示中的不变元素,从而提高效率并降低成本。缓存的提示比未缓存的提示便宜一半。这个功能对于需要重复使用相同图像或文本的应用场景非常有用。然而,提示缓存功能对图像的处理存在局限性,它只能缓存与之前完全相同的图像。OpenAI的提示缓存功能与Anthropic的缓存机制不同,它会自动缓存提示中的不变元素,而Anthropic需要手动指定缓存内容。OpenAI的提示缓存功能可以对文本进行部分匹配,并自动缓存相似的元素,从而降低成本和提高速度。对于需要提供大量上下文信息的应用场景,提示缓存功能可以显著提高效率。

Key Insights

What were the key announcements at OpenAI Dev Day 2024?

OpenAI Dev Day 2024 featured several key announcements, including the real-time API for developers to use the advanced voice mode, fine-tuning of vision capabilities, prompt caching, and model distillation. The real-time API allows for voice-to-voice interactions, and OpenAI hinted at adding video and vision capabilities in the future.

How does OpenAI's real-time API differ from traditional APIs?

The real-time API uses WebSockets, which allows for asynchronous communication. Unlike traditional APIs where a request is sent and a response is received, WebSockets enable continuous, bidirectional communication. This allows for features like interrupting the AI, proactive messaging, and dynamic interactions.

Why is the cost of OpenAI's real-time API a concern?

The real-time API is currently expensive, costing between $9 and $18 per hour for voice conversations. This makes it cost-prohibitive for many applications, especially for subscription-based services where users might engage in lengthy conversations, potentially leading to financial losses for developers.

What is the purpose of prompt caching in OpenAI's API?

Prompt caching automatically stores elements of a prompt that don’t change, reducing the cost and time of processing repeated inputs. This is particularly useful for applications where the same context or knowledge is reused frequently, making interactions more efficient and cost-effective.

What is model distillation and how is it used in OpenAI's API?

Model distillation involves training a smaller, more efficient model using the outputs of a larger, more powerful model. This allows for the creation of specialized models that are cost-effective and tailored to specific use cases, such as analyzing contracts or generating specific types of content.

What are the limitations of OpenAI's vision fine-tuning?

Vision fine-tuning, while useful for specific tasks like web navigation or document analysis, may not always outperform dedicated vision models. It can be time-consuming and expensive, and the benefits may not justify the costs compared to using existing specialized models for tasks like facial recognition or object detection.

What is the Corey Hotline and how does it demonstrate OpenAI's real-time API?

The Corey Hotline is a demonstration of OpenAI's real-time API, where users can interact with an AI named Corey in a conversational manner. It showcases the API's ability to handle interruptions, maintain context, and provide human-like responses, although the voice still has identifiable AI characteristics.

How does Microsoft Copilot integrate OpenAI's technology?

Microsoft Copilot integrates OpenAI's technology to provide advanced voice and vision capabilities. It aims to act as an AI companion for both personal and professional tasks, such as summarizing news, assisting with work documents, and even helping with everyday activities like finding dog parks.

What is the significance of OpenAI's Canvas feature?

Canvas is OpenAI's response to Claude's Artifacts, allowing users to collaborate on writing and coding within a workspace. It provides an editor where users can make changes, ask the AI to improve content, and adjust parameters like length or style, offering a more interactive and productive AI experience.

What are the ethical concerns surrounding Meta Ray-Ban's doxing capabilities?

Meta Ray-Ban's smart glasses, combined with facial recognition technology, can instantly identify and provide personal information about strangers in real-time. This raises significant privacy concerns, as it enables social engineering and potential misuse of personal data, such as names, phone numbers, and addresses.
