## Gemini 4 Carbon (Gemini Carbon 4)

Gemini 4 Carbon (frequently searched as Gemini Carbon 4) is Google DeepMind's flagship frontier model announced on October 28, 2026, arriving just two weeks after Gemini 4 Argon. Built for sustained, multi-day agentic engineering and autonomous cyberdefense, Gemini 4 Carbon debuted at #1 on the Artificial Analysis Intelligence Index v5.0 with a score of 59—outperforming Claude Opus 5.5 (58), GPT-6 Astra (57), and Gemini 4 Argon (50) while using 29% fewer output tokens per task than Claude Opus 5.5.

Across the cybersecurity defense lifecycle, Gemini 4 Carbon establishes a decisive frontier lead: it scores 88.2% on SEC-bench Pro for discovering real-world software vulnerabilities, 54.8% on ExploitGym for validating exploitability, and 71.0% on Collinear's CWE-bench for generating root-cause patches. Internal Google evaluations show more than a 2x uplift in generating vulnerability-free code over Gemini 4 Argon, and the Chrome security team reported 10x higher patch quality compared to competing frontier models. Beyond security, Carbon jumps +89 Elo to #4 (1768) on WebDev Arena, reaches 96.2% F1 on GraphWalks (256K–1M long-context reasoning), scores 80.0% on RiemannBench, and ranks #1 of 93 models on Vals AI's Legal Research Bench.

Google is rolling out Gemini 4 Carbon through a deliberate staged release: initial access began via Google's Fairwind Program for vetted cybersecurity defenders and U.S. government pre-release testing partners, followed by broader availability across Google AI Ultra and Pro subscriptions, Google AI Studio, Vertex AI, and the agent-first Google Antigravity IDE. API pricing launches with a 50% introductory discount at $2.00 per 1M input tokens and $10.00 per 1M output tokens ($4.00 / $20.00 standard pricing after the promotional period), with cached input tokens discounted by 95% ($0.10–$0.20 per 1M).

**Pricing & Plans:** API introductory launch pricing (50% off): $2.00 / 1M input tokens and $10.00 / 1M output tokens ($4.00 / $20.00 standard rate), plus 95% off cached input tokens ($0.10–$0.20 / 1M). Staged access via Google's Fairwind Program, Google AI Studio, Vertex AI, and Google AI Ultra ($99.99–$199.99/mo) & Pro ($19.99/mo).

- **#1 on Artificial Analysis Intelligence Index v5.0 (Score 59):** Leads overall frontier intelligence across HLE-Diamond, Terminal-Bench-Science (64.8%), AA-Omniscience, and AutomationBench-AA, scoring 9 points higher than Gemini 4 Argon at comparable per-task cost ($7.76).
- **Full-Lifecycle Cybersecurity Defense (SEC-bench Pro 88.2%):** State-of-the-art autonomous vulnerability discovery (88.2% SEC-bench Pro), exploit validation (54.8% ExploitGym), and root-cause patching (71.0% CWE-bench), generating 2x more secure code than Argon.
- **Multi-Day Long-Horizon Agentic Engineering:** Persists for days through dead ends and complex tool-call loops across large codebases and low-level systems, scoring 65.2% on Terminal-Bench 4.0 and 1768 Elo (#4, +89 Elo) on WebDev Arena.
- **1M-Token Native Multimodal Context (96.2% GraphWalks F1):** Processes text, code, images, audio, speech, and video within a 1-million-token context window, achieving 96.2% F1 on 256K–1M GraphWalks and 72.5% on Chartography.
- **Hardened Alignment & Prompt-Injection Resilience:** Combines chain-of-thought monitoring, real-time misuse defenses, and high-pressure alignment training that cuts unsupported claims and fabrications by 2x compared to Gemini 4 Argon.

**Strengths:** Ranked #1 overall on Artificial Analysis Intelligence Index v5.0 (59), ahead of Claude Opus 5.5 (58) and GPT-6 Astra (57); Unmatched cybersecurity benchmark leadership on SEC-bench Pro (88.2%), ExploitGym (54.8%), and CWE-bench (71.0%); Aggressive 50% launch API discount ($2 / $10 per 1M tokens) with 95% off context caching and 29% lower output token consumption than Claude Opus 5.5; True 1M-token multimodal context window with a 12-point jump on 256K–1M GraphWalks (96.2% F1 vs Argon's 84.2%)

**Limitations:** Staged rollout starts with Google's Fairwind Program for cyber defenders before general availability in Google AI Studio and Gemini apps; Standard API pricing doubles to $4.00 / $20.00 per 1M tokens once the introductory 50% launch discount period ends; High reasoning effort modes exhibit longer time-to-first-answer-token latency (9.75s–23.45s) on deep multi-step tasks

## Layout

Layout takes a natural-language brief and turns it into a running full-stack application. The builder understands what you describe, then produces a functional codebase using a modern stack: interactive frontend UI plus a backend powered by Supabase for Postgres storage, authentication and real-time data sync. The output is not a static mockup — it is an app you can click through, extend and deploy.

Because the whole project is editable through both a visual canvas and the underlying code, Layout straddles the no-code and pro-code worlds. Founders can tweak layouts and copy without touching a file, while engineers can export the entire project, push it to their own repository, or continue development locally. The v2 release emphasises faster generation with better structural results.

Connectivity is the other half of the story: Supabase supplies instant auth and real-time databases, Stripe handles monetisation so an app can start accepting payments without custom integration code, and GitHub sync is on the roadmap so generated output stays aligned with professional CI/CD workflows. Hosting is included under a Layout domain, with custom domains and team collaboration flagged as coming soon. A free tier with limited generation credits lets you evaluate the builder before upgrading.

**Pricing & Plans:** Freemium. A free tier provides limited generation credits so you can explore the platform; paid plans unlock more features and higher usage. Exact plan prices are published on the Layout pricing page.

- **Prompt-to-app generation:** Describe your idea in chat and Layout produces a working codebase with frontend UI, routing and project structure rather than a static mockup.
- **Supabase-backed backend:** Managed Postgres, instant REST and GraphQL APIs, real-time sync over WebSockets, built-in authentication and row-level security come out of the box.
- **Stripe payments integration:** Connect a Stripe account in seconds to accept one-time purchases, subscriptions or tiered memberships without writing payment code.
- **Code export and ownership:** Export the entire project codebase to continue development locally or host it anywhere, so you are never locked into the platform.
- **Built-in hosting:** Deploy finished projects instantly on a Layout subdomain with no server setup; support for custom domains is in development.

**Strengths:** Generates a genuinely full-stack app — database, auth and APIs included, not just front-end markup; Works for non-coders and developers alike thanks to simultaneous visual and code-level editing; Full code export prevents vendor lock-in and lets you host anywhere; Integrations with Supabase and Stripe cover the two most common early-stage needs

**Limitations:** Team collaboration and custom domain support are still marked as coming soon; Free tier credits are limited for heavier experimentation; Not a substitute for engineering review on security-critical production apps
