The change only applies to experiments created after that date; earlier experiments keep their recorded model. Because Argon is a higher‑tier model, token pricing will also shift, so users should verify their billing settings.\n\nFor users in Japan (and Canada), Gemini 2.5 Pro has been discontinued for Gemini Enterprise apps that store data locally, and those workloads have been switched to the domestic Gemini 3.5 Flash version. The model remains available in global, US and EU regions.\n\nOpenAI also revealed a partnership with Google Cloud, making GPT‑6 Astra, GPT‑6.1 Sol and GPT‑6 Luna available in the Model Garden on an invite‑only preview. General availability is expected within the next few weeks, and usage will be billed through the Google Cloud account, simplifying contracts for customers who primarily use Google Cloud.","keyPoints":["From Oct 26, AlphaEvolve experiments without a specified model will default to Gemini 4 Argon, replacing Gemini 3.8 Flash.","In Japan, Gemini 2.5 Pro is discontinued for domestic Gemini Enterprise apps and switched to Gemini 3.5 Flash.","OpenAI’s GPT‑6 Astra, GPT‑6.1 Sol and GPT‑6 Luna are now available on Google Cloud via invite‑only preview, with GA expected in weeks."],"whyItMatters":"The changes affect billing and model performance for cloud AI experiments, and give Google Cloud users direct access to OpenAI’s latest models without separate contracts.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Google","OpenAI","AlphaEvolve","Microsoft"],"models":["Gemini 4 Argon","Gemini 3.8 Flash","Gemini 3.5 Flash","GPT-6 Astra","GPT-6.1 Sol","GPT-6 Luna"],"people":[]},"firstPublishedAt":"2026-10-24T20:44:00Z","updatedAt":"2026-10-24T20:44:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"Today's Cloud AI Memo (10/25): 'Default Models' are changing starting tomorrow—AlphaEvolve's switch to Gemini 4 Argon and OpenAI models coming to Google Cloud","url":"https://note.com/ruru_4869keiei77/n/n4038100382c0?hl=en","publishedAt":"2026-10-24T20:44:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"AI Assistants Battle for 2026 Dominance","url":"https://digestai.news/thread/anthropic-opens-claude-duet-research-preview-for-us-pro-and-max-users","storyCount":3},"cite":{"text":"Digest AI, \"Google Cloud switches AlphaEvolve default to Gemini 4 Argon and adds OpenAI GPT-6 models\", 24 October 2026, https://digestai.news/story/google-cloud-switches-alphaevolve-default-to-gemini-4-argon-and-adds-o","publisher":"Digest AI","title":"Google Cloud switches AlphaEvolve default to Gemini 4 Argon and adds OpenAI GPT-6 models","datePublished":"2026-10-24T20:44:00Z","url":"https://digestai.news/story/google-cloud-switches-alphaevolve-default-to-gemini-4-argon-and-adds-o"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
