OpenAI updated ChatGPT’s default model to GPT‑5.5 Instant on May 5, 2026, positioning it as a smarter and more accurate daily-use model.
The company said internal evaluations showed 52.5% fewer hallucinated claims than GPT‑5.3 Instant on high-stakes prompts in medicine, law, and finance.
OpenAI also reported a 37.3% reduction in inaccurate claims on difficult conversations that users had previously flagged for factual errors.
The release adds improvements in image and photo analysis, STEM question answering, and model decisions about when to invoke web search.
OpenAI said responses are now shorter and clearer, with less overformatting, fewer unnecessary follow-up questions, and less gratuitous emoji use.
The post also emphasizes stronger use of previously shared context for personalization, with new controls around how responses are tailored.
GPT‑5.5 Instant is available as the default ChatGPT model for all users, according to the release.

Google introduced Multi-Token Prediction drafters for Gemma 4, positioned as an inference-speed upgrade for the model family
The company says the approach can deliver up to a 3x speedup, targeting generation latency rather than a new model release
The method adds lightweight drafters that predict multiple upcoming tokens, while the main Gemma 4 path verifies and advances decoding from those candidates
Google highlighted integration paths across LiteRT-LM, MLX, and Hugging Face Transformers, which points to both on-device and developer-stack use cases
Gemma 4 31B is part of the supported lineup mentioned in the release materials, alongside the broader Gemma 4 ecosystem
Google says Gemma models were downloaded more than 60 million times in the first few weeks, giving the optimization immediate relevance for existing deployments
The update focuses on inference bottlenecks and throughput efficiency, which may reduce serving cost or improve responsiveness for apps built on Gemma 4
Google published the announcement on 2026-05-05 through its official blog, and the core speedup and rollout details align with supporting coverage

Anthropic introduced ten ready-to-run agent templates for financial services work, including pitchbooks, KYC screening, valuation review, and month-end close tasks.
The templates ship as plugins for Claude Cowork and Claude Code, and as cookbooks for Claude Managed Agents on the Claude Platform.
Each template packages task-specific skills, governed data connectors, and subagents for focused steps such as comparables selection or methodology checks.
Anthropic said the release is paired with Claude Opus 4.7, which it says leads Vals AI's Finance Agent benchmark at 64.37%.
Claude add-ins for Microsoft 365 now extend the workflow into Excel, PowerPoint, and Word, with Outlook listed as coming soon.
Anthropic said context can carry across those apps, so work started in a model can continue into decks or documents without re-entering the same instructions.
New connectors add governed real-time access to providers including Dun & Bradstreet, Financial Modeling Prep, Guidepoint, IBISWorld, SS&C IntraLinks, Third Bridge, and Verisk.
Moody's also launched an MCP app that brings proprietary credit ratings and company data covering more than 600 million public and private companies into Claude.
