OpenAI has recently announced several significant updates and new offerings as of November 2023:

1. GPT-4 Turbo: This is an enhanced version of the GPT-4 model, notable for its 128K context window, allowing it to process the equivalent of over 300 pages of text in a single prompt. It's also optimized for better performance and is cheaper than the previous version, with a 3x lower price for input tokens and a 2x lower price for output tokens【20†source】.

2. Function Calling Updates: The updated function calling feature in GPT-4 Turbo allows for more complex interactions, such as calling multiple functions in a single message. This improvement enhances the model's ability to handle tasks that require multiple actions simultaneously【21†source】.

3. Improved Instruction Following and JSON Mode: GPT-4 Turbo now exhibits better performance in tasks that require precise following of instructions. Additionally, a new JSON mode ensures the model's output is a syntactically correct JSON object, useful for developers working with JSON in the Chat Completions API【22†source】.

4. Reproducible Outputs and Log Probabilities: The introduction of a seed parameter allows for reproducible outputs from the model, enhancing its utility in debugging, unit testing, and control over model behavior. OpenAI also plans to introduce a feature for returning log probabilities of the most likely output tokens generated by GPT-4 Turbo and GPT-3.5 Turbo【23†source】.

5. Updated GPT-3.5 Turbo: Alongside GPT-4 Turbo, OpenAI has released an updated version of GPT-3.5 Turbo with a default 16K context window and improvements in instruction following, JSON mode, and parallel function calling【24†source】.

6. Assistants API: This new API helps developers build AI-based applications with specific instructions and the ability to call models and tools to perform tasks. It introduces capabilities like Code Interpreter and Retrieval, simplifying the development of AI apps【25†source】【26†source】.

7. GPT-4 Turbo with Vision: This feature allows GPT-4 Turbo to process images as inputs in the Chat Completions API, enabling a range of applications like image analysis and document reading with visual content【28†source】.

8. DALL·E 3 API: The DALL·E 3 API is now available for developers, allowing integration of this image creation tool into apps and products. This API includes built-in moderation features to prevent misuse【29†source】.

9. Text-to-Speech API: A new text-to-speech model offers human-quality speech generation from text, with six preset voices and two variants optimized for real-time use and quality【30†source】.

10. Experimental Access to GPT-4 Fine Tuning: An experimental program is being introduced for fine-tuning GPT-4, aimed at achieving significant improvements over the base model. Additionally, a Custom Models program is being launched for organizations needing highly tailored GPT-4 models【31†source】.

11. Lower Prices and Higher Rate Limits: OpenAI has reduced prices across its platform for various models and increased the tokens per minute limit for GPT-4 customers, aiding in scaling applications【32†source】【33†source】.

12. Copyright Shield and New Releases: OpenAI introduced Copyright Shield to protect customers against legal claims of copyright infringement. They also released Whisper large-v3, an improved automatic speech recognition model, and the Consistency Decoder, an enhancement for the Stable Diffusion VAE decoder【34†source】【35†source】.

These updates demonstrate OpenAI's continuous efforts to improve its offerings and provide more advanced tools and APIs for developers and researchers.

what about sam altman

Sam Altman, who co-founded OpenAI and served as its CEO, has been removed from his position. This decision, announced on November 17, 2023, came after a deliberative review process by OpenAI's board. The board concluded that Altman was not consistently candid in his communications with other board members, which hindered the board's ability to fulfill its responsibilities. As a result, the board expressed a lack of confidence in Altman's ability to continue leading OpenAI【49†source】【50†source】.

In response to his departure, Altman expressed his fondness for his time at OpenAI in a tweet, suggesting he would speak about his future plans later. Greg Brockman, a co-founder of OpenAI along with Altman, will step down as chairman of the board but will continue to serve as OpenAI’s president. Mira Murati, previously OpenAI's CTO, has been appointed as the interim CEO. OpenAI has begun a formal search for a permanent CEO【51†source】【52†source】.

Altman's removal was unexpected, especially considering his prominent role in the company's recent activities, including hosting OpenAI's first developer conference, OpenAI DevDay, and speaking at the Asia-Pacific Economic Cooperation conference. Altman has been a significant figure in steering OpenAI since its inception, co-founding the company with notable figures like Peter Thiel and LinkedIn co-founder Reid Hoffman. He has also been actively involved in shaping regulatory responses to AI, engaging with global leaders and participating in U.S. congressional hearings【53†source】【54†source】.

The reasons behind Altman's departure remain somewhat unclear, but it appears to be related to his relationship with OpenAI's board and the company's unique corporate governance structure. OpenAI operates a for-profit subsidiary, OpenAI Global, LLC, which is fully controlled by OpenAI's nonprofit. This structure allows the for-profit arm to commercialize its technology while adhering to the nonprofit's mission of attaining artificial general intelligence (AGI) that can outperform humans in most economically valuable work【55†source】.
