Advanced AI assistant known for nuanced understanding, detailed analysis, and high-quality long-form content creation. Excels at complex research, strategic planning, and maintaining consistent brand voice. As of May 2026, Anthropic doubled rate limits across all paid plans and eliminated peak-hour throttling for Pro and Max — the result of a compute partnership with SpaceX's Colossus One facility. Also in research preview as of May 2026: Claude Managed Agents with a 'dreaming' capability — agents that autonomously review their own past sessions and curate better memory between projects, making repeat client work progressively more efficient.

Google's flagship AI model family. Gemini 3.1 Pro (released February 19, 2026) is a major leap: scored 77.1% on ARC-AGI-2 benchmark (up from 31.1% — more than doubled), tops both Claude Opus 4.6 (68.8%) and GPT-5.2 (52.9%), and sets a record on GPQA Diamond graduate-level science questions at 94.3%. API pricing: $2/million tokens vs. Claude Opus at $15/million. Real-world caution: early testing flagged planning loops where the model reasons in circles without producing output. Context window spec is 1M tokens but reliability degrades past ~120-150K tokens in practice. Also includes Google Lyria 3 for free music generation inside Gemini.

Google's AI research assistant built around 'notebooks.' With Deep Research enabled, it can take a question, design a research plan, search across many sources, read your uploaded documents, and return structured, source-cited summaries and reports. It's designed to replace many paid research tools for content marketers, consultants, and analysts.
