AI News Today: OpenAI Confirms “12 Days” Event, Meta AudioBox 2 Launches, & NVIDIA Hits $4T

Thursday, December 4, 2025, marks the beginning of the counter-offensive. After spending the first half of the week watching Google Gemini 3 and AWS Olympus dominate the headlines, OpenAI has finally signaled its move. Sam Altman has confirmed the return of the “12 Days” release strategy starting tomorrow, promising a fortnight of updates to close out the year. Meanwhile, Meta has quietly revolutionized AI audio with the launch of AudioBox 2, and NVIDIA has ridden the week’s generative AI hype to a historic financial milestone.

OpenAI Announces “12 Days of Shipping” to Reclaim the Spotlight

The silence from San Francisco is over. Following leaks earlier this week regarding ad infrastructure in ChatGPT, OpenAI CEO Sam Altman tweeted a simple “Day 1 starts tomorrow,” accompanied by a snowflake emoji. This confirms widespread rumors that OpenAI is bringing back its holiday release marathon, a strategy designed to dominate the news cycle for two consecutive weeks.

While no specific products were named in the teaser, code sleuths and insiders suggest the lineup includes:

• Sora Turbo: A public-facing, faster version of their video generation model, likely available to Plus and Pro users immediately.
• Operator: A “computer-using agent” designed to compete directly with Anthropic’s Claude Opus 4.5 and Google’s Antigravity platform.
• GPT-4.5: A potential interim model update to bridge the gap to GPT-5, offering improved reasoning speed.

The timing is strategic. By spreading releases over 12 days, OpenAI aims to drown out the buzz surrounding Google’s Gemini 3 launch, forcing the industry to talk about OpenAI every single day through mid-December.

Meta AudioBox 2: The New King of Real-Time Translation?

While OpenAI teases the future, Meta delivered a tangible breakthrough today with the release of AudioBox 2. Mark Zuckerberg unveiled the model as the “world’s most advanced universal translator.”

Unlike Google’s Gemini Live, which focuses on conversational fluidity, AudioBox 2 focuses on voice preservation. The model can translate speech into 200+ languages in real-time while perfectly cloning the speaker’s original timbre, emotion, and prosody.

• Why it matters: This effectively kills the “dubbing” industry. A demo showed a creator speaking English, with AudioBox 2 instantly generating Japanese and Spanish audio tracks that sounded exactly like the creator, not a generic robot.
• Open Access: True to Meta’s strategy, the weights for the base model have been released to researchers, putting immense pressure on closed-source audio startups like ElevenLabs.

NVIDIA Hits $4 Trillion Market Cap on “Rubin” GPU Leaks

The AI arms race requires ammunition, and the market has decided NVIDIA is the only supplier that matters. Following the massive compute demands revealed by Amazon’s 2-trillion parameter Olympus model on Tuesday, NVIDIA stock surged again today, pushing the company’s market cap past $4 Trillion for the first time.

The rally is fueled by leaked specs of the upcoming “Rubin” GPU architecture (the successor to Blackwell). Supply chain reports from Taiwan indicate that Rubin chips will offer 4x the memory bandwidth of current generation hardware. This bandwidth is the critical bottleneck for running the massive multimodal agents released by Google and Anthropic this week. The market is betting that as models get larger, NVIDIA’s moat only gets wider.

Perplexity AI Disrupts E-Commerce with “Shopping Pro”

In a move to monetize search, Perplexity AI launched a new feature today called Shopping Pro. While Google is fighting the model wars, Perplexity is attacking the browser.

Shopping Pro allows “Buy with AI” functionality. Instead of clicking links to visit different retailers, Perplexity’s agent compares prices, reads reviews, selects the best item, and executes the checkout process on the user’s behalf (using stored payment credentials). This shifts AI search from “informational” (giving you answers) to “transactional” (doing the work), posing a direct threat to the traditional ad-based search models of Google and Amazon.

The “Shipmas” Season Has Begun

As we head into Friday, the pace of AI innovation is accelerating rather than slowing down for the holidays. The industry is bracing for OpenAI’s “Day 1” announcement tomorrow. Will it be a minor feature update, or will they drop the “Operator” agent to neutralize Anthropic’s lead?

Stay tuned to AI News Today; we will be covering every drop of the 12-day event as it happens.
