COMPARISONS

Best LLM for coding: how to choose

Coding models compared by price and fit: Claude Sonnet and Opus, GPT Codex, Kimi K2.7 Code, DeepSeek V4 Pro and Gemini Pro. Test them on one key in your own tools.

THE SHORT ANSWER

There is no single best coding LLM for every team. Claude Sonnet and Opus, GPT Codex models, Kimi K2.7 Code, DeepSeek V4 Pro and Gemini Pro are the common candidates. Pick two by budget, run them on your own tasks in your coding agent, and compare cost per accepted change. All are available on one Tokely key.

Shortlist by budget

Premium: Claude Opus and GPT pro or Codex variants. Mid-range: Claude Sonnet and Gemini Pro. Low-cost: Kimi K2.7 Code and DeepSeek V4 Pro, which are priced well below the premium tier per token.

Agents are dominated by input tokens

Coding agents resend the repository context and tool definitions on every turn, so input and cache-read prices matter more than output price. Prefer models with prompt caching and check cache-read rates in the table.

Measure on your codebase

Give each candidate the same 10 to 20 real tickets in your agent, count accepted changes and total cost, and keep the cheapest model that meets your bar. Use the expensive model only for the hardest tasks.

One key for every model

Every model on this page is available through one OpenAI-compatible endpoint and one balance, with routing modes, bounded fallback, spending limits and request logs.

Questions before you switch

What is the cheapest good coding model?

Kimi K2.7 Code and DeepSeek V4 Pro are the low-cost candidates on Tokely; whether they are good enough depends on your tasks, so test them against a premium model.

Can I use these models in Cline, Roo or Claude Code?

Yes. OpenAI-compatible agents connect to https://api.tokely.me/v1; Claude Code uses the native /v1/messages endpoint for Claude models. See the coding agents guide.
