 A group of AI agents produced a proof for the Navier-Stokes Millennium Prize Problem, OpenAI claims.
OpenAI announced it's sharing a solution to the Navier-Stokes Millennium Prize Problem, one of math's deepest unsolved challenges, produced by a group of agents using a next-generation model more capable than GPT-6 Astra. This would be a landmark achievement if independently verified.
However, mathematician Tristan Buckmaster has alleged the proof builds on his and Levent Alpöge's recent related work without proper attribution, a claim OpenAI denies. Given the dispute, this claim should be treated as unconfirmed pending independent mathematical review.
Key Capabilities:

• Major Claim: OpenAI says its agents solved one of seven Millennium Prize Problems in mathematics.
• Disputed Origin: A mathematician alleges the proof builds on his uncredited prior research, which OpenAI denies.
• Unverified Status: Not yet confirmed by independent mathematical peer review, so treat with caution.

Grok connects directly to Coinbase, letting users check balances and execute trades using plain language.
Grok announced users can connect their Coinbase accounts on grok.com and use natural-language commands to check balances, analyze holdings, execute trades, or cancel orders for available assets. Coinbase CEO Brian Armstrong responded enthusiastically to the update.
The feature builds on Coinbase's existing "Coinbase for Agents" tools, letting AI handle financial tasks with user-set guardrails. This comes amid growing interest in AI-driven trading tools across the industry.
Key Capabilities:

• Natural Language Trading: Execute or cancel trades using plain chat commands instead of a trading interface.
• Full Account Access: Check balances and analyze holdings directly from within a Grok conversation.
• User Guardrails: Built on Coinbase's agent tools, which include user-set limits for AI-driven actions.

Three new models launch together, letting users remix existing tracks or create from images and audio.
Suno launched v6, introducing three models: a flagship v6 for polished results, experimental v6-wild, and a free v6-mini for quick generations. It can turn images, videos, and voice memos into music, and lets users make precise changes to songs they've already created.
Built with licensed music following recent copyright settlements, the models include royalty structures for rights holders. New editing features let users adjust song sections with simple instructions, mash up tracks, or isolate individual instruments.
Key Capabilities:

• Multi-Input Creation: Turns images, videos, or voice memos directly into finished music tracks.
• Precise Editing: Lets users edit specific song sections or isolate instruments with simple instructions.
• Three Tiers: Offers a flagship v6, experimental v6-wild, and a free v6-mini option.

H3 Reference Turbo Realtime lets creators guide video generation with far more visual control than before.
Reactor introduced H3 Reference Turbo Realtime, the latest model by MiniMax. It streams video with audio and guide generation using up to 9 reference images, giving creators significantly more control than earlier versions.
This pushes real-time, reference-guided video generation further, letting users blend multiple visual inputs into a single coherent stream. It's available today on Reactor for developers to start building with immediately.
Key Capabilities:

• More References: Supports up to 9 reference images at once, far more than typical video models.
• Live Streaming: Generates video with audio in a real-time streaming format, not just static clips.
• Available Now: Live today on Reactor for developers to start building with right away.
