The best LLM models for coding

1. Claude Opus 4.6
The #1 coding model, unmatched at multi-file reasoning and real-world bug fixing
Benchmark: 80.8% SWE-bench
2. Gemini 3.1 Pro
Google's latest flagship, doubled reasoning vs Gemini 3 Pro
Benchmark: 80.6% SWE-bench
3. MiniMax M2.5
Best open-source model, 230B params, strong agentic coding at low cost
Benchmark: 80.2% SWE-bench
4. GPT-5.4
Best all-rounder, first model with native computer use surpassing human performance
Benchmark: 77.2% SWE-bench
5. Grok 4.2 Beta
The most architecturally unique model right now, four specialized AI agents running in parallel on every complex query
Benchmark: Top 10 SWE-bench Verified (Beta, exact score TBA)
In any case, out of all the models I would choose Opus 4.6, especially if you can afford the 20× Max subscription
Claude still handles coding the best in my experience
But things are changing very fast, so keep an eye on new LLM models as they appear
