What is GPT-5.2-Codex?

GPT-5.2-Codex is OpenAI’s most capable agentic coding model, engineered for professional software engineering and cybersecurity use cases. It builds on the strengths of GPT-5.2 while introducing optimizations for long-running coding sessions. The model excels at maintaining context across extended workflows using native context compaction. GPT-5.2-Codex performs reliably in large repositories and complex project structures. It achieves state-of-the-art results on SWE-Bench Pro and Terminal-Bench 2.0, reflecting strong real-world coding performance. Native Windows support improves reliability for cross-platform development. Enhanced vision capabilities allow the model to interpret design mocks, diagrams, and screenshots. GPT-5.2-Codex supports iterative development even when plans change or attempts fail. The model also shows substantial gains in defensive cybersecurity tasks. It can assist with vulnerability discovery and secure software development workflows. Additional safeguards are built in to address dual-use risks. GPT-5.2-Codex advances the frontier of agentic software engineering.

What is Claude Sonnet 5.5?

Claude Sonnet 5.5 is Anthropic’s faster, lower-cost Claude 5.5 model for well-scoped professional work, software development, agentic workflows, and content creation. Anthropic positions it below Claude Opus 5.5 for the most complex open-ended work, but says it can perform comparably on some benchmarks when run at higher effort settings. The model delivers a particularly large improvement in coding, including a 70.6% result on Terminal-Bench 4.0, 46.2% on FrontierCode at Max effort, and 55.5% on CursorBench 4.0. It also scores 1844 on GDPval-AA, 1811 on AA-Briefcase, 64.5% on Humanity’s Last Exam with tools, and 80.1% on OSWorld 2.1 partial. Anthropic reports that Sonnet 5.5 is better at long-horizon work, image understanding, collaboration, and codebase comprehension than Sonnet 5. The company also highlights design-oriented improvements, including the ability to produce polished documents, spreadsheets, slides, and user interfaces with less editing. Sonnet 5.5 generates output more than 30% faster than its predecessor and is Anthropic’s fastest Sonnet model to date. Although its listed token prices are unchanged from Sonnet 5, Anthropic says greater token efficiency can reduce per-task cost by up to 30%. Pricing is $2 per million input tokens, $10 per million output tokens, $2.50 per million cache-write tokens, and $0.20 per million cache-read tokens. The model includes cyber safeguards, biology safeguards, reasoning-extraction protections, and preserved-thinking controls, with some higher-risk cyber requests falling back to Sonnet 5. Claude Sonnet 5.5 is available with zero data retention across Claude products, the Claude Platform, AWS, Google Cloud, and Microsoft Azure under the model name claude-sonnet-5-5.
