GitHub adds model choice

GitHub has added model selection for Claude and Codex agents on github.com, letting users choose an Anthropic or OpenAI model when they start an agent task. (github.blog) GitHub posted the change in its changelog on April 14, 2026. The company said model selection now works for the Claude and Codex third-party coding agents on github.com, similar to the existing Copilot cloud agent flow. (github.blog) In GitHub’s setup, a coding agent is a tool that can take a task, work on it asynchronously, and return code changes or a draft pull request. GitHub said users can assign issues and pull requests to Claude, Codex, Copilot, or multiple agents, and can call them with `@claude`, `@codex`, or `@copilot` in pull request comments. (github.blog) The update keeps that workflow inside the same GitHub web interface while changing the model underneath. GitHub’s docs say users can choose a model from a dropdown when managing cloud agents, instead of being locked to a single default model. (docs.github.com) GitHub started this multi-agent push on February 4, 2026, when it announced Claude by Anthropic and OpenAI Codex in public preview on GitHub and Visual Studio Code under what it called “Agent HQ.” On February 26, 2026, GitHub expanded Claude and Codex availability to Copilot Business and Pro users. (github.blog 1) (github.blog 2) GitHub’s documentation says third-party agents are available across GitHub Copilot Pro, Pro+, Business, and Enterprise plans, but they must be enabled in account or organization policies before people can use them. Organization settings can separately allow Anthropic Claude and OpenAI Codex, and those agents only get access to repositories where Copilot cloud agent is enabled. (docs.github.com 1) (docs.github.com 2) The pricing and control piece is part of the rollout. GitHub says advanced models and some agent features consume “premium requests,” and those counters reset monthly, with separate tracking for Copilot coding agent usage since November 1, 2025. (docs.github.com 1) (docs.github.com 2) On GitHub’s current pricing page, the Pro plan includes Claude and Codex on GitHub and Visual Studio Code, plus 300 premium requests a month and the option to buy more. GitHub also says paid plans include access to models from Anthropic, Google, OpenAI, and others, which puts the new Claude-and-Codex selector inside a broader multi-model Copilot strategy. (github.com) The immediate effect is narrower than a full product relaunch: GitHub changed the picker for third-party agents on github.com, not the basic fact that Claude and Codex were already available in Copilot. What changed on April 14 is that businesses using those agents on the web can now choose which Anthropic or OpenAI model runs the task. (github.blog)
