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

Solar Pro 4 is an advanced AI model designed to effectively complete real-world tasks such as document analysis, tool execution, and deliverable production, ceasing operations when there is insufficient evidence. This model is specifically tailored for extensive and intricate workloads that span multiple documents, run commands in a terminal, and coordinate numerous tool interactions over several steps. With a remarkable 512K context window and the capacity for up to 128K output tokens, it enables the seamless incorporation of contracts, reports, and data files into a single workflow without the need for division. It can process both input and output in English, Korean, and Japanese, while users have the flexibility to adjust reasoning levels for either in-depth analysis or swift, real-time responses. Designed for precision, Solar Pro 4 maintains accuracy across lengthy documents, multi-turn tool applications, and terminal operations, ensuring that values and conclusions remain consistent throughout sequential deliverables, including Excel spreadsheets, comprehensive reports, and presentation slides. Moreover, its architecture supports collaborative projects by allowing teams to work simultaneously on various aspects of a task, enhancing overall productivity and efficiency.
