OpenAI has recently launched new audio features and tools aimed at enhancing the capabilities of AI agents. The releases include updated transcription and text-to-speech models, as well as tools for building AI agents. The audio models, named gpt-4o-transcribe and gpt-4o-mini-transcribe, promise better performance than the previous Whisper models, achieving lower word error rates across multiple languages and demonstrating improvements in challenging audio conditions like varying accents and background noise. These models are built on top of language models, making them potentially vulnerable to prompt injection attacks.
OpenAI also unveiled new tools for AI agent development, featuring a Responses API, built-in web search, file search, and computer use functionalities, alongside an open-source Agents SDK. Furthermore, they introduced o1 Pro, a new reasoning model, positioned for complex reasoning tasks, comes with a high cost, priced at $150 per million input tokens and $600 per million output tokens. The gpt-4o-mini-tts text-to-speech model introduces "steerability", allowing developers to control the tone and delivery of the model.

OpenAI has recently unveiled a suite of new tools aimed at simplifying the development of AI agents. This release includes the Responses API, designed as a flexible foundation for building agents, along with built-in capabilities for web search, file search, and computer use. An open-source Agents SDK is also part of the package, intended to help developers orchestrate both single-agent and multi-agent workflows, providing the essential building blocks for creating reliable AI agents.
OpenAI has also introduced o1 Pro, its latest AI reasoning model, but it comes with a steep price tag. At $150 per million input tokens and $600 per million output tokens, o1 Pro is significantly more expensive than previous models, costing ten times the price of the standard o1 model and twice as much as GPT-4.5. OpenAI claims that o1 Pro "thinks harder" and provides "consistently better" responses, especially for complex tasks, but early benchmarks suggest the improvements may be incremental.

OpenAI has unveiled its Agents SDK, along with a revamped Responses API, built-in tools, and an open-source SDK. These tools simplify the development of AI agents for enterprise use by consolidating the complex ecosystem into a unified framework. This platform allows developers to create AI agents capable of performing tasks autonomously. The Responses API integrates with OpenAI’s existing Chat Completions API and Assistants API to assist in agent construction, while the Agents SDK helps users orchestrate both single and multi-agent workflows.
This initiative addresses AI agent reliability issues, recognizing that external developers can offer innovative solutions. The SDK reduces the complexity of AI agent development, enabling projects that previously required multiple frameworks and specialized databases to be achieved through a single, standardized platform. This marks a critical turning point as OpenAI recognizes the value of external contributions to the advancement of AI agent technology. With web search, file search, and computer use integrated, the Responses API enables agents to interact with real-world data and internal proprietary business contexts more effectively.
