Claude vs Gemini for coding

Anthropic's and Google's flagship models, compared on what matters when they write code: independent coding votes, price per million tokens, context window, and how they behave inside an editor. Scores and prices are read live, not copied from a launch post.

Claude and Gemini flagships compared for coding: independent votes, price and context, read live.

The short answer

Today's flagships are Claude Opus 5.5 and Gemini 4 Argon. On LMArena's coding board, where developers vote between two anonymous answers to the same programming prompt, Claude Opus 5.5 is ahead right now (1545 against 1539). A gap of a few points is within noise; a gap of tens of points is a real difference people notice.

The full head-to-head, with benchmarks and the monthly cost of three workloads, is on the Claude Opus 5.5 vs Gemini 4 Argon page, and every model's coding rating is on the best AI model for coding ranking.

Price and context

Model	Input / 1M	Output / 1M	Context
Claude Opus 5.5 anthropic/claude-opus-5-5	₹395	₹1,975	1M
Gemini 4 Argon google/gemini-4-argon	₹197	₹987	1.05M

Coding work is input heavy. An agent in your editor sends the open files, the error, and often a slice of the repository with every turn, so the input rate and prompt caching decide most of the bill. Both providers cache repeated prefixes, and Rapid Router bills cached tokens at the provider's cache rate automatically.

How they differ in practice

Claude models are widely used in agentic coding tools for following long instructions and editing several files in one pass. Gemini models bring very long context and native handling of images, video and audio, which helps when the task includes screenshots or logs alongside code. Both support tool calling and JSON output through the same OpenAI-compatible request on Rapid Router.

The honest way to choose is to run both on a week of your own tasks. With one key you can, without a second account or a second bill.

Using both in your editor

Our Cursor, Cline, Continue and Roo Code guides set the base URL to https://rapidrouter.ai/api/v1. After that, switching between the two is a change of model string.

Common questions

Is Claude or Gemini better for coding?

On LMArena's coding board at the time of writing, Claude Opus 5.5 rates 1545 and Gemini 4 Argon rates 1539. The ratings move as votes come in; the live numbers are on our coding ranking page.

Which is cheaper for coding?

Claude Opus 5.5 costs ₹395 in and ₹1,975 out per million tokens; Gemini 4 Argon costs ₹197 in and ₹987 out. Coding sessions send a lot of context, so the input price matters more than it does for chat.

Can I use both in the same editor?

Yes. Tools such as Cursor, Cline, Continue and Roo Code accept an OpenAI-compatible base URL. Point them at Rapid Router and switch between Claude and Gemini by changing the model string.

Which has the bigger context window?

Claude Opus 5.5 reads up to 1M tokens and Gemini 4 Argon up to 1.05M in one request, per our catalogue. Both hold a large repository slice; neither holds a whole large codebase.
