Grok 4.5, SpaceXAI’s latest coding model, is now available as a selectable model in GitHub Copilot across VSCode and other Copilot products (including cloud agents and the Copilot CLI). For some businesses and enterprises the model must be enabled in Copilot settings; Grok 4.5 is also offered directly via the SpaceXAI console at $2 per million input tokens and $6 per million output tokens.
Project HydraFusion is a research preview for GitHub Copilot that implements runtime orchestration of models from multiple providers, dynamically assembling execution plans and using three execution patterns based on task complexity. Early evaluations reported in the preview indicate high task quality while substantially reducing operational costs.
GitHub announced a research preview of Project HydraFusion in GitHub Copilot. In controlled offline evaluations, HydraFusion’s selective coding workflows matched or exceeded the evaluated Opus 5 baseline while reducing estimated workflow cost, according to a post on the GitHub Blog.
GitHub published a beginner guide on the GitHub Blog showing how to run parallel agents in the GitHub Copilot app. The post aims to help users move from apprehension to productive use of multiple agents in the app.
A GitHub AI & ML blog post outlines why shorter model outputs can sometimes increase costs and describes how GitHub Copilot reduces wasted work across the full coding task. The post appears on The GitHub Blog but does not detail specific implementation changes in this summary.
