Artificial intelligence companies have rolled out significant updates to their models in May 2026. OpenAI released GPT-5.5 with improved reasoning capabilities, while Anthropic updated its Claude model with enhanced safety features.
Other notable releases include Google's Gemma 4 and xAI's Grok voice mode. Meta also introduced Muse Spark, its latest creative AI tool for content generation.
