Jeff Dean writes, “Have a glimpse at this! Nice work, @AndrewDai and Elorian folks!” https://twitter.com/AndrewDai/status/2111142161584628060 In the quoted announcement, Andrew Dai introduces Glimpse as their first visual thinking model, claiming competitive frontier performance compared with Astra on key public visual reasoning benchmarks.
Google is rolling out Gemini 4 Argon globally to developers, enterprises, and paid subscribers, emphasizing coding, professional knowledge work, multimodal understanding, and sustained task execution. API pricing is $2 per million input tokens and $10 per million output tokens through November 30, rising to $4 and $20 on December 1. Google reports that Argon worked unattended for 11 hours on ADK optimizations, with engineers merging two changes; Ethan Mollick described improvements but noted remaining weaknesses in complex multi-agent tasks.
UBTECH introduces Thinker-WM, a multimodal world model that jointly models RGB video, depth, and robot actions through a shared Unified Dynamics Transformer. In material supplied by UBTECH and republished by QbitAI, the company reports leading results on WorldOlympiad, EWMBench, and WorldArena1.0 Track-1, including scores of 0.740 on WorldOlympiad and 4.66 on EWMBench. The model supports six capability modes through shared weights, and adding depth improved RoboTwin single-task success by 15 percentage points over a baseline without depth.
Elorian released Glimpse on Friday as a research preview with API access and a waitlist-only chat interface. Its visual scratch space lets it crop image regions, retrieve video frames, and run code to measure or compare visual content during reasoning. Pricing is $0.60 per million input tokens and $3 per million output tokens; Elorian’s evaluations report performance above GPT-6 Astra on scientific chart reasoning and short-form video captioning.
The Verge’s three reviewers spent a week testing five Nvidia RTX Spark laptops, finding capable graphics and generally workable Windows on Arm apps alongside high prices, weaker CPU performance than Apple rivals, and demanding local AI workloads. Sean Hollister’s Asus ProArt P16 lasted roughly 5 hours to 5 hours and 40 minutes during everyday work. Their local AI experiments encountered substantial battery drain, heat, slow responses, and uneven results, despite configurations offering up to 128GB of unified memory.
Why it matters: The hands-on comparisons show how large unified memory and capable graphics translate into everyday tradeoffs in local AI workloads, battery life, and software compatibility.
Google DeepMind’s Gemini 4 Argon scored 97.5 percent on ARC-AGI-3 using the Provider Adapter Harness at a cost of $4,800, behind GPT-6 Astra’s 99.9 percent. Its score fell to 49.8 percent at low reasoning in the Standard Harness, where API problems prevented completion of all games. Epoch AI placed Argon at 165 ECI points, close to Opus 5.5 and GPT-6 Astra, although early estimates ranked it eighth in math and sixth in software engineering.
Why it matters: The comparison shows how testing environments can change benchmark standings, providing context for interpreting Argon’s proximity to leading models alongside its weaker math and software engineering results.
Aravind Srinivas says Gemini 4 Argon has set a new SoTA on the Wide-And-Deep-Research (WANDR) benchmark and is now available to all Perplexity users in fast search and Computer (agent) modes. https://t.co/0U671BhbMj The quoted @perplexity_ai announcement specifies availability for Pro and Max subscribers. https://t.co/n1TyI9RhBX
Why it matters: The post identifies availability across fast search and Computer modes, while its broader access claim differs from the quoted announcement limiting availability to Pro and Max subscribers.
