OpenAI's flagship AI platform — had what Everyday AI's Jordan Wilson called 'the most consequential product week in years' (April 21-27, 2026): GPT-5.5 'Spud' launched with 60% fewer hallucinations, scored 84.9 on GDPval benchmark, and ties/outperforms expert humans 85% of the time. ChatGPT Images 2.0 launched simultaneously — production-grade typography, 2K resolution, multilingual text rendering, 8 coherent images per prompt, beat every other image model by 236 points in blind testing. ChatGPT Workspace Agents launched — persistent AI assistants that run complex multi-step workflows automatically, even offline. Caveat: GPT-5.5 is optimized primarily for agentic coding tasks — content marketers focused on writing quality may not notice dramatic improvements over previous versions.

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.
