Sundar Pichai: In three years, today's AI will look as primitive as a flip phone. The progress we're about to see will surprise people.” “We are in that rare moment in technology. The curve is so steep.” “People will look back three years from now and say, ‘You mean you couldn't do those things?’” “We are all laying the foundation for agents, but agents will be very common.” “People will be relying on them to get things done in a more seamless way.” “Any content can go from any modality to any modality. We've shown hints of it with Nano Banana, Veo, and Omni.” “It doesn't matter how the content was originally created. People can consume it in many different forms.”

Gemini 4 Carbon vs Opus 5.5 tested both with the same prompt [Voxel Floating Kingdom] • Opus 5.5: high reasoning, 1h 15m, ~$12 • Gemini 4 Carbon: high reasoning, 1h 15m, ~$0.95 at that price difference, Carbon is looking like the better deal. but which model actually did better here?

Happy Gemini 4 Hydrogen Day? Logan just posted “Gemini” again, exactly what he posted before Carbon dropped yesterday. Hydrogen could be next. here’s what we should expect based on early checkpoints tested on Arena as “gemini-3.8-flash”: > fast generation, especially for coding and big jump over 3.8 > strong 3D coding with lots of detail and creativity > much cheaper than the larger Gemini 4 models, as expected of a Flash model. if Google can deliver this level of quality at Flash speeds and pricing, it's going to be a seriously competitive model. are you excited for the Hydrogen bomb?

Gemini 4 Carbon (Voxel Floating Kingdom) - high reasoning in Cursor, ~ 1h 15m ~ $0.95 in API costs over 3 million voxels, this much detail and creativity, all for less than a dollar. (est. 11.7M tokens) easily the cheapest SOTA-level model i’ve tested so far. the price-to-quality ratio is impressive. Google cooked insanely hard with this model
Gemini 4 Carbon is now available. It’s our strongest model, built to dig deeper, handle long-horizon tasks, and multi-step reasoning. If Argon is great for complex tasks, Carbon is the model you bring in for your hardest problems.

POV: OpenAI in the AI race after Gemini 4 Carbon and Fable 5.2 dropped
We're turning our lessons from defending OpenAI into practical tools for our customers. On Thursday, join us at Cyber at the Frontier, a live keynote, for our latest cyber announcements. Working with our frontier models, we've identified and resolved important vulnerabilities in our own code and infrastructure. That experience is informing the tools and playbooks we're building to help other security teams strengthen their defenses. @gdb shares what we've learned and why security teams should keep putting the latest models to work as capabilities improve. Tune in on November 12 at 10 a.m. PT: openai.com/cyber-at-the-fron…

Fable 5.2 vs Gemini 4 Hydrogen (Pelican SVG Test) same prompt: create an svg of a pelican riding a bicycle across five animated seasons. • Fable 5.2 (high, Claude Code): ~25 mins, ~$25 • Gemini 4 Hydrogen (Arena): ~5 mins, cost unknown. Hydrogen held up surprisingly well against Fable and could be 10x cheaper than Fable when it launches. Fable 5.2 did a really impressive job overall but is the extra detailing worth the cost?

Grok 4.8 is finally coming this week Elon says the 2.5T model has finished pre-training and is now in RL and it’s a major jump over 4.7 xAI also rebuilt the RL and inference systems from scratch in C/C++, which explains the long delay the model is set to begin rolling out to Grok Bot users later this week one question: will it be on par with Opus 5.5 when it drops?
Replying to @cradrrat
We have dumped JAX/SGLang and rewritten the entire RL and inference stack from scratch in C/C++, which took some extra time. Training (aka pre-training) is done. Lot of cleanup was needed on the SFT data to get that mostly right. Now, 4.8 is in RL and the evals are starting to climb. We will do a soft rollout to Bot users later this week and see how it goes. Grok 4.8 will bear no resemblance to 4.7 (thankfully). It is not yet incredible, but, this time, the foundations are built right, so I expect it to evolve to be something special.

the Anthropic effect is already kicking in less than 24 hours after Fable 5.2 launched, Gemini team is already back to vague posting. Carbon has already appeared in Google Cloud’s billing catalog, and new Hydrogen checkpoints have been testing on Arena for days now. the timing is interesting. we might see wider Carbon access or Gemini 4 Flash sooner than expected.

Fable 5.2 (3D Sailing Ship) - medium reasoning on claude code, est. ~38 minutes ~$17 Anthropic cooked with this model. it built this in Three.js, no Blender or external 3D assets were used we’re getting to the point where 3D scenes built entirely with code are starting to look like actual renders. OpenAI really has to step up now and drop 6.2 Astra

GPT 6.2 Sol vs Opus 5.5 [3D Sailing Ship Test] same prompt: create an interactive sailing ship in three.js, make it detailed as possible: - GPT 6.2 Sol: ~27 minutes and cost $3 - Opus 5.5: max reasoning ~1hr 35 mins and cost $16 Sol did a better job recreating the ship itself, especially the shape, sails and lighting but Opus has a more detailed background overall. be honest, which one would you pick here?

[GPT-6.2 Sol] 3D Sailing Ship Test this model is seriously good at 3D coding. asked it to recreate a sailing ship in Three.js, all in a single HTML file with no external 3D assets. > the interior, water reflections, lighting and day/night transitions all look so good. this could even beat Opus 5.5 in 3D coding. I’ll run the same test and see.
GPT-6.2 Sol (PS5 Controller SVG) GPT-6.1 Sol (Max) has started routing to the newer model for some users, including me. > it’s a big upgrade over the previous 6.1 models even Astra, the detailing here is impressive tbh if you want to check yours, ask: “do you know Fable 5? don’t search the web or use memory” the routed version recognizes it, while regular 6.1 Sol doesn’t.

new OpenAI and Anthropic models have been spotted in Devin CLI, just hours apart. • claude-donut-eap and new Mythos 5.1 reasoning tiers • aurora-alpha and halo-alpha with five reasoning levels they could possibly be Fable 5.5 and GPT-6.2 Astra/Sol they look prepped for release, but with the recent safety concerns, i’m not convinced we’ll see them released just yet.

Gemini 4 Hydrogen vs GPT 6.1 Sol same prompt: create a hypercar in three.js and make it as realistic and detailed as possible (add decals, make it shiny) > gemini 4 hydrogen came super fast under ~5 mins in Arena > gpt 6.1 sol ran on max reasoning in codex cli, took ~20 mins GPT-6.1 Sol did a good job too, but 20 minutes feels pretty slow for a prompt like this. what do you think? PS: GPT 6.2 Sol isn’t dropping this week btw :(
Gemini 4 Hydrogen: new checkpoint (Floating Kingdom) spotted as "gemini-3.8-flash" on Arena and it built this in a single prompt under ~10 mins > there are currently two checkpoints, likely the team is A/B testing different variants can't say much about it yet but it seems newer flash models from gemini are getting a big boost.

Happy Qwen 4 Day to those who celebrate? the Qwen team just posted a teaser, and it looks like Qwen 4 is finally about to drop. the signs have been there to see for weeks: - Alibaba confirmed Max, Plus, Flash and 27B last month - Qwen 4 checkpoints on Arena: (Kalmia, Kerria, Kentia) - Qwen Code added Qwen 4 Max, Plus and Coder references - last Thursday, Alibaba's CTO even said "Qwen 4 next week" the checkpoints on Arena were impressive. I’m really curious to see how the final models perform, especially the open-weight 27B. we should expect announcements anytime soon, are you looking forward to this launch?
The becoming begins.

Gemini 4 Hydrogen (SVG Pelican on Bicycle Test) it took around 5 minutes to finish and each season has its own little details after Fable 5.5's realistic pelican set a new bar, this one held up pretty well for a flash model. the new checkpoint is really impressive tbh, it’s looking real close to Sonnet 5.5 in 3D coding. which model would you want me to compare it with?

Introducing GPT-6 Cyber, OpenAI’s new cybersecurity model. it’s the same model behind yesterday’s Linux kernel research, where it helped • find 948 vulnerabilities could let hackers gain access • reproduced over 1,700 security flaws • generated patches to fix them with all the hacks we’ve been seeing lately, this is a much needed release and we really need more cyber models but, when are we getting GPT-6.2 Astra and 6.2 Sol?
Introducing GPT‑6 Cyber: a major advance in security research that pairs stronger capabilities with better model alignment. The model powered the Linux kernel research we announced yesterday, and security teams at companies like Mozilla, Palo Alto Networks, Calif, and Cisco—alongside our own at OpenAI—are already putting it to work. GPT-6 Cyber is available to select Daybreak Red customers and we are expanding access over time. openai.com/index/introducing…
