Behind every O-mega agent is a powerful AI model that processes requests, reasons through problems, and generates responses. O-mega supports models from leading providers including OpenAI, Anthropic, Google, and others—giving you access to the latest advances in artificial intelligence.
Each agent can run on a different model, allowing you to optimize for specific use cases. Some agents might benefit from faster, more efficient models, while others might need the deeper reasoning capabilities of more advanced options.
Default Models
For most users, the default model works perfectly out of the box. O-mega automatically selects optimized default models based on your subscription plan, choosing options that provide the best balance of capability, speed, and cost for your tier.
These defaults aren't static—they're continuously updated as new models are released and benchmarked. When a better option becomes available for your plan level, you automatically benefit without needing to change any settings.
The practical implication is that you don't need to think about model selection unless you have specific requirements. The platform handles the complexity of choosing appropriate models, letting you focus on what you want your agents to accomplish.
Changing Your Agent's Model
If you do want to use a different model—perhaps for specific capabilities or to optimize for a particular use case—you can change the setting at any time.
To change your agent's model:
- Open the agent you want to configure
- Go to the agent's Info section
- Find the Model setting
- Select from the available options in the dropdown
- Save your changes
The models available to you depend on your subscription plan. Higher-tier plans unlock access to more powerful (and more resource-intensive) models that might not be available on lower tiers.
Changes take effect immediately. Your agent will use the new model for all subsequent interactions and tasks.
Separate Model for Browser Automation
O-mega allows you to set a different model specifically for browser automation tasks. This separation exists because browser automation has different requirements than general conversation.
Reasons you might want a different browser model:
- You want a faster model for web navigation to speed up multi-step automations
- You want to optimize costs for high-volume browsing tasks that don't need maximum reasoning power
- A specific model performs better for your particular automation use case
This setting appears in the same Info section as the main model selection. If you don't set a separate browser model, your agent uses its main model for all tasks including browser automation.
When to Change Models
Most users should stick with the defaults, but there are situations where switching models makes sense.
Consider changing models when:
- Tasks are too slow - A faster model might complete work more quickly if you don't need maximum quality
- Quality isn't sufficient - A more capable model might produce better results for complex reasoning tasks
- Costs are too high - A more economical model might handle your workload at lower resource consumption
- Specific requirements - Some models excel at particular tasks like coding, mathematical reasoning, or creative work
The key is matching the model's strengths to your actual needs. Using the most powerful model available isn't always better if a lighter model can handle your use cases effectively.
Model Updates
O-mega regularly updates the available models as providers release new versions. When new models become available, they appear in your model selection dropdown.
Your default model setting automatically benefits from improvements. If you've explicitly chosen a specific model, you'll continue using that version until you manually switch—giving you stability when you need it and access to the latest when you want it.
