GPT-4o
OpenAI
The fastest reliable generalist. Best when you need an agent that calls tools, writes code, and ships.
- Mature function calling
- Voice + vision in one model
- Predictable latency
- Smaller context than rivals
- Output can feel templated

Claude 3.5 Sonnet
Anthropic
The thinker. Best when quality and nuance matter more than raw speed — writing, analysis, refactor.
- Best-in-class reasoning
- Cleanest code refactors
- Careful, honest tone
- Slower on long outputs
- More refusals on edge prompts
Gemini 1.5 Pro
The librarian. Best for projects with huge context — whole codebases, long research, video.
- 1M token window
- Native video understanding
- Strong factual grounding
- Less consistent on agents
- Newer ecosystem
Where this fits in IINT apps
BridgeMaster bridges your conversations across all three models — search history from one, merge it into a chat with another, and never re-explain context. The model picker is a single tap.
The Master App Builder routes each step of a build to the model that's strongest at it: Gemini reads your whole project, Claude writes the refactor, GPT-4o executes the tool calls. You don't choose — the build flow does.
