Model capabilities

Babbily gives you access to multiple models from one chat surface. The best model depends on what you are trying to do, how much context you need, and which capabilities are available for your plan.

Use the model picker as the source of truth for your account, but these recent additions can help when you are choosing quickly:

Capability signals

The model picker and composer can show what a model supports. Common capability differences include:

• File types and file size behavior.
• Context window size.
• Tool availability.
• Image generation or editing.
• Video generation or editing.
• Memory personalization availability.
• Speed and reasoning depth.
• Multi-step or agentic task behavior.
• Codebase-scale context handling.
• Fast mode availability.
• Sunsetting status for older model options.
• API usage budget impact.

If a file type, tool, or media action is hidden, the selected model may not support it. When a model is marked Sunsetting, it remains available for continuity, but Babbily recommends choosing a newer model for new work when one is available.

​

Advanced reasoning and coding work

Some models are built for specialized advanced work, such as comparing multiple approaches, reviewing code, working across large files, or planning multi-step engineering tasks. Choose these models when the task benefits from depth, synthesis, or a larger working context. For better results:

• State the goal, constraints, and expected output.
• Include only the files or excerpts the model needs.
• Ask for a plan before large edits or refactors.
• Ask the model to call out uncertainty, risks, and tradeoffs.

​

Switch models during work

You can switch models when the task changes. Good switching patterns:

• Start with a faster model to brainstorm.
• Switch to a stronger reasoning model for decisions or plans.
• Switch to a file-capable model before attaching documents.
• Switch to a media-capable model for image or video work.
• Use Fast mode when it appears and you want quicker supported replies, then check your API usage budget for heavier work.
• Start a new thread if older context is steering the answer in the wrong direction.

​

Usage considerations

More advanced model work can use more of your API usage budget, especially when it includes tools, long file context, image generation, video generation, or deep research. For budget-sensitive work:

• Use shorter prompts when the task is simple.
• Avoid unnecessary file attachments.
• Turn tools Off for model-only drafting.
• Use search or deep research only when sources matter.
• Check your usage card before running image or video generation.

​

Troubleshooting

If a capability is missing:

• Switch to a model that supports it.
• Change tool mode from Off to Auto or Manual.
• Check whether your plan supports the feature.
• Check your remaining API usage budget.
• Try a new thread if the current one has a long or confusing context history.
