GitHub Copilot Has Removed All Gemini Models from Its Web Interface

GitHub quietly dropped every Gemini model from Copilot Chat on github.com on May 20, along with GPT-5.2 Codex and GPT-5.4 nano. OpenAI and Claude models remain available. GitHub says it's about reliability — the scope of what was cut says more than the explanation does.

GitHub removed all Gemini models from Copilot Chat on github.com on May 20. The official changelog entry is brief: “We are limiting the list of available models on github.com so that we can consistently ensure reliable responses.”

The removal covers every Gemini model on the web interface. It also removes GPT-5.2 Codex and GPT-5.4 nano on the OpenAI side. Claude and OpenAI models otherwise remain.

What changed

Copilot Chat at github.com now has a narrower model picker. The longer list of options — which had included multiple Gemini generations alongside Claude and GPT variants — is gone for Gemini entirely.

Developers who were using Gemini models through github.com chat will need to switch to a remaining option or use Gemini directly through Google AI Studio, Antigravity, or another product.

This doesn’t affect VS Code or JetBrains IDE integrations, where model availability follows separate rollout decisions. The IDE integrations got a related update the same week: auto model selection in VS Code now routes requests by task type rather than defaulting to a single model. The web interface and the IDE extensions are moving in different directions.

The stated reason vs. the broader picture

GitHub’s explanation — consistent, reliable responses — is a real concern for a platform product. When you expose many model options, you own the support and reliability consequences of each one. Narrowing the list is a real product decision.

But the scope of the cut is categorical, not selective. Every Gemini model is gone, not just ones with known quality issues. GitHub is owned by Microsoft, which has a multi-billion dollar partnership with OpenAI. Google is a direct competitor. The practical effect of the change is that GitHub’s web interface now surfaces only the partner’s models alongside Claude.

This fits a pattern that’s been building since early 2026. In March, GitHub removed free models from the student plan. Also in March, Gemini 3 Pro was deprecated. The May 20 change is the most sweeping step yet, and each move has been framed in terms of quality or reliability while also reducing Google’s presence on GitHub’s surfaces.

On the same day GitHub dropped Gemini from the web, a separate update brought semantic issue search to Copilot Chat. Users can now search GitHub Issues using semantic understanding rather than keyword matching, which makes it easier to find related issues by meaning rather than by exact phrasing.

It’s a useful addition that got minimal attention in the context of the model changes.

What this means in practice

If you use Copilot Chat at github.com and had a preference for Gemini, that option is gone from this surface. The remaining choices are Claude models at various tiers and OpenAI’s current lineup. For most developers, the quality difference in a chat context is small enough that the change is more noticeable as an absence than as a practical downgrade.

If model flexibility on Copilot matters to you, the VS Code extension is currently the better place for it. GitHub is clearly investing more in the IDE experience than in the web chat interface.
