Microsoft has launched Phi-4-Reasoning-Plus, a 14B parameter open-weight model designed to excel at complex tasks like coding, math, and logic, challenging much larger systems in raw reasoning power.

The Details:

  • Trained on 16B tokens and fine-tuned using supervised learning and reinforcement learning, Phi-4-Reasoning-Plus was built for structured, step-by-step thinking.

  • Despite its compact size, it beats larger models like DeepSeek-R1-Distill-70B on key benchmarks such as AIME 2025 and math-focused tests.

  • It uses custom  tags to separate reasoning steps from final answers, making its logic more transparent and usable in audit-heavy workflows.

  • The model supports 32K-token inputs (tested up to 64K) and runs on popular frameworks like Hugging Face Transformers, vLLM, llama.cpp, and Ollama.

  • Licensed under MIT, it’s free to use, fine-tune, and deploy, even in commercial and enterprise environments.

Why it matters:

Phi-4-Reasoning-Plus is proof that smarter training can beat brute-force size. For enterprises and developers, it offers a lean, powerful model that’s easier to deploy, interpret, and scale, without sacrificing reasoning quality. Microsoft is pushing the boundaries of what ā€œsmallā€ models can really do.

NVIDIA & ANTHROPIC

In a rare public feud, Nvidia hit back at Anthropic’s push for tighter chip export rules, mocking the startup’s claims about smuggling AI chips into China.

The Details:

  • Anthropic published a blog post warning about chip smuggling into China, citing tactics like hiding hardware in ā€œprosthetic baby bumpsā€ or with ā€œlive lobsters.ā€

  • Nvidia fired back, calling the claims ā€œtall talesā€ and accusing Anthropic of trying to win through regulation instead of innovation.

  • The Biden-era ā€œAI Diffusion Rule,ā€ set to begin May 15, restricts exports of advanced AI chips and model weights to slow China’s AI progress.

  • Anthropic, backed by Amazon, proposed tightening controls further and lowering export thresholds for Tier 2 nations to close smuggling loopholes.

  • Nvidia CEO Jensen Huang recently praised China’s AI capabilities, saying Huawei has made major progress and is now a top global tech force.

Why it matters:

This clash shows deepening tensions between top AI players over policy, power, and global dominance. With export rules tightening and political shifts looming, the stakes for U.S. leadership in AI have never been higher. This isn’t just a tech debate—it’s a race to define who controls the future of intelligence.

OpenAI is launching a new shopping mode in ChatGPT that lets users compare prices, view reviews, and buy products directly in chat. It’s ad-free and includes images, links, and pricing. The feature is rolling out soon to all users, including free accounts.

Amazon unveiled Nova Premier, a powerful AI model with a 1M token context window for deep reasoning and multimodal tasks. It powers multi-agent workflows and can train smaller versions like Nova Micro, now available on Amazon Bedrock for scalable, cost-efficient deployments.

Tavus unveiled Hummingbird-0, a zero-shot lip-sync model that needs only one video to match any voice. Built on Phoenix-3, it delivers ultra-realistic results with no training required. Try it now on Fal or via Tavus’ API.

Meta’s Ray-Ban smart glasses now auto-record voice commands by default, with no way to fully disable it—only delete or turn off voice control. The change helps train Meta’s AI, but raises privacy concerns as the AI-powered mic stays live unless fully shut off.

Duolingo is phasing out human contractors, shifting content creation and other repetitive tasks to AI. CEO Luis von Ahn says future hiring will only happen if AI can’t do the job. AI is also now used in hiring decisions and performance reviews.
