Overview

Ollama v0.18.3 includes a targeted fix for API compatibility with Microsoft's Copilot Chat integration. The update addresses how model names are returned from the /api/show endpoint.

What Changed

The Problem: Copilot Chat integration previously preferred using general.basename for model identification, but this name isn't typically displayed directly to users and may be shared across multiple models, creating ambiguity.

The Solution: The /api/show endpoint now returns req.Model instead, which provides the specific model value returned from the /api/tags endpoint. This gives Copilot Chat the correct, unique model identifier it needs for proper integration.

Developer Impact

If you're using Ollama with Copilot Chat or have custom integrations that rely on the /api/show endpoint, this change ensures you receive more accurate and disambiguated model names. No action is required for most users, as this fix improves compatibility out of the box.
