+description: How to configure a reasoning models
+---
+
+# Reasoning models
+
+Many 
+"reasoning" models have restrictions on streaming and setting the temperature parameter.
+Aider is configured to work properly with these models
+when served through major provider APIs.
+
+You may need to [configure model settings](/docs/config/adv-model-settings.html)
+if you are using them through another provider
+and see errors related to temperature or system prompt.
+
+Include settings for your new provider in `.aider.model.setting.yml` file
+at the root of your project or in your home directory.
+
+## Temperature, streaming and system prompt
+
+You should find one of the existing model setting configuration entries
+for the model you are interested in, say o3-mini:
+
+```yaml
+- name: o3-mini
+  edit_format: diff
+  weak_model_name: gpt-4o-mini
+  use_repo_map: true
+  use_temperature: false             # <---
+  editor_model_name: gpt-4o
+  editor_edit_format: editor-diff
+```
+
+Pay attention to these settings, which must be set to `false`
+for certain reasoning models:
+
+- `use_temperature`
+- `streaming` 
+- `use_system_prompt`
+
+Here's an example of
+the settings to use o3-mini via Azure.
+Note that aider already has these settings pre-configured, but they
+serve as a good example of how to adapt the main model
+settings for a different provider.
+
+```yaml
+- name: azure/o3-mini
+  edit_format: diff
+  weak_model_name: azure/gpt-4o-mini
+  use_repo_map: true
+  use_temperature: false             # <---
+  editor_model_name: azure/gpt-4o
+  editor_edit_format: editor-diff
+```
+
+## Thinking tokens
+
+There is also a `remove_reasoning` setting, which takes the name of a tag.
+This is used to remove everything inside that XML tag pair.
+
+When using DeepSeek R1 from Fireworks, the reasoning comes back inside
+`<think>...</think>` tags, so aider's settings
+include `remove_reasoning: think` to remove that part of the response.
+
+Aider will still *display* think reasoning output, it just won't use it
+to find file editing instructions, etc.
+
+```yaml
+- name: fireworks_ai/accounts/fireworks/models/deepseek-r1
+  edit_format: diff
+  weak_model_name: fireworks_ai/accounts/fireworks/models/deepseek-v3
+  use_repo_map: true
+  extra_params:
+    max_tokens: 160000
+  use_temperature: false
+  editor_model_name: fireworks_ai/accounts/fireworks/models/deepseek-v3
+  editor_edit_format: editor-diff
+  remove_reasoning: think                 # <---
+```
