Description
Claude Sonnet 5.5 is a general-purpose AI model from Anthropic built for everyday professional tasks, agentic coding, knowledge work, and fast iteration. It is the second model in the Claude 5.5 family and is intended to complement Claude Opus 5.5 by offering lower-cost performance on more clearly defined workloads. Anthropic reports that Sonnet 5.5 generates output more than 30% faster than Sonnet 5 and usually completes tasks with fewer tokens. Pricing remains $2 per million input tokens and $10 per million output tokens, with cache reads priced at $0.20 per million tokens. On Terminal-Bench 4.0, the model scores 70.6%, compared with 10.3% for Sonnet 5, while also posting sizable improvements on FrontierCode, CursorBench, and other coding benchmarks. Its knowledge-work results are also substantially stronger, including a GDPval-AA score of 1844 and an AA-Briefcase score of 1811, both close to Claude Opus 5.5. Anthropic says early testers found the model faster, more collaborative, more concise, and particularly strong at design-oriented work such as polished interfaces and presentation decks. The model supports adjustable effort levels so users can trade off speed and cost against more extended reasoning and checking. Claude Sonnet 5.5 is available through Claude apps, Claude Code, the Claude Platform, and major cloud providers including AWS, Google Cloud, and Microsoft Azure.
Description
Gemini 4 Carbon is a frontier AI model developed by Google DeepMind to support advanced cybersecurity defense, autonomous software engineering, and complex reasoning tasks. The model builds on Gemini 4 Argon with improvements in coding accuracy, long-running agent workflows, scientific problem-solving, and multimodal understanding. Its cybersecurity capabilities include identifying software vulnerabilities, validating exploitability, analyzing security risks, and generating code patches that address underlying defects. Gemini 4 Carbon achieved 88.2% on SEC-bench Pro for vulnerability detection, 54.8% on ExploitGym for exploit validation, and 71.0% on CWE-bench for vulnerability remediation in Google's reported evaluations. Its long-horizon agentic capabilities allow the model to investigate complex engineering problems, navigate dead ends, and coordinate tasks that may require extended execution. Software development features include repository-level debugging, secure code generation, full-stack web development, and automated remediation of difficult programming issues. The model also includes improved factual reliability, prompt injection resistance, instruction following, and safeguards against unintended actions. Google reports that Gemini 4 Carbon ranks first on the Artificial Analysis Intelligence Index version 5.0 with a score of 59.
