Lovable: GPT-6.1 Sol Now Available for Your App's AI Features
LovableLovable added OpenAI's GPT-6.1 Sol (openai/gpt-6.1-sol) as a model option for the AI features built into apps made with Lovable. The model targets complex coding and professional work, accepts text and image input, and responds with text. Builders can name the model in a prompt or let Lovable pick one based on the described feature.
Key Takeaways
- Lovable now supports OpenAI's GPT-6.1 Sol (
openai/gpt-6.1-sol) for the AI features inside apps built on the platform. - The model is aimed at complex coding and professional work, making it a fit for demanding in-app reasoning tasks.
- It accepts text and image input and returns text only, so image or audio generation needs a different model.
- Builders can ask for it by name in the project chat, or describe the feature and let Lovable pick the model.
- It extends the multi-model choice Lovable offered just days earlier with Gemini 4 Argon, giving builders a second major model family for app AI features.
- No separate provider setup is described, so adopting it happens entirely through the chat workflow.
GPT-6.1 Sol joins the model lineup for app AI features
Lovable now lets the AI features inside an app use OpenAI's GPT-6.1 Sol, identified as openai/gpt-6.1-sol. The model is positioned for complex coding and professional work, which makes it a candidate for in-app features that need more careful reasoning than a lightweight model provides, such as assistants that analyze documents, draft structured output, or work through multi-step tasks.
What the model accepts and returns
GPT-6.1 Sol takes text and image input and responds with text. That means an app built with Lovable can pass a user's written request together with an uploaded screenshot, diagram, or photo, and receive a written answer. It does not generate images or audio as output, so features that need those should rely on other models.
How to use it
There is no new setting to find. A builder can ask Lovable in the project chat to use GPT-6.1 Sol for a given AI feature, or describe what the feature should do and let Lovable choose the model itself. This follows the same pattern Lovable used days earlier when it added Gemini 4 Argon for app AI features, so builders can now choose between model families based on the task, cost, and quality they need.
Why it matters
Model choice is one of the main levers on the quality and cost of an AI-powered app. Adding GPT-6.1 Sol gives Lovable builders another high-capability option without wiring up a separate provider account or writing integration code, since the model is requested through the same chat-based workflow used to build the rest of the app.
