Frequently asked questions
Does Gemini really have a 2 million token context window?
Yes, Gemini 3.1 Pro offers a context window of up to 2 million tokens, which is the largest available context window among major AI models. This makes it possible to process very large documents, complete codebases, or hours of video at once. In practice, this is especially useful for analyzing large document collections or multimedia files. Most codebases fit comfortably within Claude's 1 million tokens.
Is Claude better than Gemini for programming?
In most benchmarks and user experiences, Claude scores higher on code-related tasks, particularly for complex refactoring, architecture advice, and understanding intricate type systems. However, Gemini has shown strong improvements in recent updates and is competitive for standard programming tasks. The difference is narrowing with each update, but Claude maintains an edge in consistency and accuracy.
Which model is more affordable?
Gemini offers more free capabilities through integration in Google products like Gmail and Docs. Both have a Pro tier at $20 per month. At the API level, Gemini is generally cheaper per token, while Claude offers competitive pricing for its Haiku model for simple tasks and Sonnet for most programming work.

At MG Software, we use exactly this combination. You can integrate both models into your workflow through API integrations or by switching between the chat interfaces.
How do Claude Projects compare to Gemini Gems?
Claude Projects lets you store per-project custom instructions, documents, and context that are available in every conversation. This is ideal for development teams working per repository. Gemini Gems are custom AI personas with specific knowledge and instructions. Projects is more focused on knowledge management, while Gems are more focused on creating specialized assistants with a specific personality or expertise.
Which model is better for analyzing images?
Gemini has an edge in multimodal tasks including image analysis, because it was built from the ground up as a multimodal model. Claude also supports image input and performs well at analyzing screenshots, diagrams, and UI designs. For video and audio analysis, however, Gemini is the only option, as Claude does not support these input types natively.
How quickly are both models improving?
Both models are updated multiple times per year with significant improvements. Anthropic releases new Claude versions in a cadence of four to six months, while Google updates Gemini more frequently with smaller improvements. The competition between both companies ensures that quality is rising rapidly. We recommend reconsidering your model choice at least every quarter based on the latest benchmarks and your own experiences.
