A new HydraFusion Max option is introduced, tuned for frontier capability on more demanding tasks while still considering token efficiency. Both HydraFusion and HydraFusion Max remain in research preview and are available across VS Code, the GitHub Copilot app, and GitHub Copilot CLI for Copilot Pro, Pro+, Business, and Enterprise plans with experimental features enabled. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What models does GitHub Copilot's HydraFusion use now? HydraFusion and HydraFusion Max draw from an updated model pool that includes Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna. Which models get used for a given task varies based on the orchestration workflow (Cascade or Critique) rather than being a fixed single-model choice. _Developers choosing an orchestration-based coding assistant can track model pool changes like this on daily.dev._ ### What is the difference between HydraFusion and HydraFusion Max in GitHub Copilot? HydraFusion offers a balanced approach with moderate token savings for agentic tasks needing speed, cost, and performance balance, while HydraFusion Max is tuned for frontier capability on more demanding tasks requiring the deepest reasoning and most thorough analysis. Both share the same architecture and orchestration workflow techniques and are available in research preview across VS Code, the Copilot app, and Copilot CLI. _Teams deciding which Copilot orchestration tier fits their workload can follow updates like this on daily.dev._ ### How do the Cascade and Critique workflows work in GitHub Copilot's HydraFusion? Cascade uses an initial model to attempt the task and escalates to a stronger model when needed, now with an added judging step that requests repair only when necessary. Critique uses parallel critic models that inspect the actual workspace directly via tools rather than relying mainly on text summaries, as it did previously. _Developers tuning agentic coding workflows can keep up with orchestration changes like these on daily.dev._ ## Similar posts on daily.dev - [GPT-6.1 Sol in GitHub Copilot](https://daily.dev/posts/gpt-6-1-sol-in-github-copilot-xpbo94oza) · GitHub Changelog · 0 upvotes · 0 comments - [OpenAI’s GPT-5.6 Sol, Terra, and Luna are now available in GitHub Copilot](https://daily.dev/posts/openai-s-gpt-5-6-sol-terra-and-luna-are-now-available-in-github-copilot-zqr1kvlht) · GitHub Changelog · 0 upvotes · 0 comments - [GitHub Copilot auto mode: should you disable models?](https://daily.dev/posts/github-copilot-auto-mode-should-you-disable-models--8o2kzibto) · The Art of Simplicity · 2 upvotes · 1 comments --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#github](https://daily.dev/tags/github), [#ai-coding](https://daily.dev/tags/ai-coding), [#vscode](https://daily.dev/tags/vscode) [View this post on daily.dev](https://daily.dev/posts/hydrafusion-updates-and-new-max-option-jfkj8co0c) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"HydraFusion updates and new Max option","url":"https://daily.dev/posts/hydrafusion-updates-and-new-max-option-jfkj8co0c","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/hydrafusion-updates-and-new-max-option-jfkj8co0c"},"datePublished":"2026-10-14T20:25:12.774Z","dateModified":"2026-10-14T20:25:32.791Z","description":"GitHub Copilot's HydraFusion multi-model orchestration feature received an updated model pool (Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna), per-step...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7e8577c6287118db52aacbd83e810ab9?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7e8577c6287118db52aacbd83e810ab9?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"GitHub Changelog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"GitHub Changelog","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/15004b7835da4d89b02b115871f0f6dc","url":"https://daily.dev/sources/github_updates"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/hydrafusion-updates-and-new-max-option-jfkj8co0c","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,github,ai-coding,vscode","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"GitHub Changelog","item":"https://daily.dev/sources/github_updates"},{"@type":"ListItem","position":3,"name":"HydraFusion updates and new Max option"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/hydrafusion-updates-and-new-max-option-jfkj8co0c#faq","mainEntity":[{"@type":"Question","name":"What models does GitHub Copilot's HydraFusion use now?","acceptedAnswer":{"@type":"Answer","text":"HydraFusion and HydraFusion Max draw from an updated model pool that includes Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna.
