+> The default context size for many models (such as `gpt-oss`) is 4,096 tokens, which is limiting for coding tasks.
+> You can repackage it with a larger context window:
+>
+> ```console
+> $ docker model pull gpt-oss
+> $ docker model package --from ai/gpt-oss --context-size 32000 gpt-oss:32k
+> ```
+> Alternatively, models like ai/glm-4.7-flash, ai/qwen2.5-coder, and ai/devstral-small-2
+> come with 128K context by default and work without repackaging.
