## 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

## GitLoop

GitLoop indexes your repository so an AI assistant can reason over your actual code, configuration and conventions. Instead of pasting snippets into a general chatbot, you ask questions in natural language and get answers grounded in files, modules and processes that really exist in your project. The indexing is built to stay fast and accurate on sizeable codebases.

Beyond question answering, GitLoop automates several recurring engineering chores. It drafts documentation for features, files and modules, generates unit tests tailored to your existing patterns, and runs an AI review agent over pull requests and commits to flag problems before they reach production. The agent behaves more like a reviewer than a linter: it leaves comments and replies in context.

Repository topics include codebase insights and complexity mapping, natural-language search, onboarding support for new developers, and bug detection. GitLoop supports Git hosting platforms including GitHub and GitLab, and its published pricing comparison places its paid tier below comparable general-purpose coding assistants. A free plan covers basics, with premium tiers for larger teams and higher volume.

**Pricing & Plans:** GitLoop uses a freemium model: a free plan covers basic capabilities for small projects and evaluation, while premium subscription plans add advanced features, higher processing volume and dedicated support. The site's own comparison lists a paid tier around $15/month against roughly $20/month for comparable general assistants. Check the official pricing page for current tiers.

- **Chat with your repository:** Ask questions in plain language and get answers drawn from your actual files, structure and conventions rather than generic snippets.
- **AI pull request and commit review:** An automated reviewer inspects code changes, spots potential bugs and vulnerabilities, and posts contextual comments and replies.
- **Documentation generation:** Generate descriptions for functions, modules and features so onboarding and reference material stay close to the real code.
- **Unit test generation:** Ask for tests and GitLoop searches the codebase, analyses the relevant code and produces tailored test cases.
- **Natural language codebase search:** Navigate large projects by describing what you are looking for, with fast indexing that keeps search responsive.
- **Onboarding and code explanation:** New team members can request explanations of features, processes and relationships to ramp up faster.

**Strengths:** Answers are grounded in your real repository rather than a pasted snippet; Covers chat, review, docs and tests in one tool; Supports both GitHub and GitLab repositories; Published pricing undercuts many general-purpose coding assistants

**Limitations:** Value depends on codebase size and how quickly indexing completes; AI review still needs human sign-off before merging; Feature depth differs between free and premium tiers
