Retrieval-augmented generation, or RAG, combines a generative model with a search step that supplies relevant information at request time. A system converts the query into a searchable representation, retrieves passages from approved sources, and includes them as context for the model’s response. This approach can provide current or organization-specific facts without retraining the model and can support citations. Quality depends on document preparation, indexing, permissions, retrieval ranking, context limits, and the model’s ability to use evidence correctly. RAG reduces some unsupported claims but does not eliminate them: sources may be outdated, relevant material may be missed, and the model may still distort or ignore retrieved information.
Claude Haiku 5.5 cuts costs for everyday AI tasks, with API rates up to 20x below Sonnet and Anthropic-reported benchmark gains over GPT-6 Luna.
Google’s SynthID Detector is now available globally for image, video and audio checks. It detects supported AI watermarks, rather than proving a file is real.
Google Playground turns prompts into browser games without coding. Unity Spark will add a more advanced creation path, with a closed beta coming soon.
Google’s Nano Banana 2.1 improves image quality, text and editing consistency while cutting its image-output token price to a quarter of Nano Banana Pro’s rate.
OpenAI will watermark eligible ChatGPT and Codex text in the EU, but restricted detector access and editing-related limitations complicate the promise of identifying AI writing.
Google unveils Gemini 4 Argon, its most powerful AI model yet, with a one-million-token output limit, introductory API pricing, and a phased rollout.
Anthropic says Claude Opus 5.5 approaches Fable-level performance while costing 40% less to run than Opus 5 on typical workloads. Sonnet and Haiku 5.5 will follow in the coming weeks.
Alibaba unveiled its Zhenwu V900 AI chip and confirmed plans for a Qwen model of up to 10 trillion parameters, alongside a target of more than 20 gigawatts of cloud capacity by 2032.
SpaceXAI has released Grok 4.7, a coding and knowledge work model priced the same as Grok 4.6 but built on a larger base model with new safety testing and benchmark comparisons against rivals.
Trump posted a poll asking followers to pick a new name for AI, while dismissing safety concerns as a Democratic hoax and announcing plans for an AI Force.
