What are the best LLMs?

As of July 2026, the best-LLM shortlist is Anthropic's Claude Fable 5, OpenAI's GPT-5.6 family, and Google's Gemini 3.1 Pro — but which one is best for you depends entirely on the task. Here's the honest breakdown right now:

• Claude Fable 5 leads coding and agentic work, topping SWE-bench Verified at 95.0% — though it's priced like the specialist tool it is.
• Gemini 3.1 Pro leads scientific and abstract reasoning benchmarks like GPQA Diamond, at a noticeably lower price per token.
• GPT-5.6 — OpenAI's newest family, generally available since July 9, 2026 — ships in three tiers (Sol, Terra, and Luna), so you can trade capability for cost inside one lineup.

The real skill isn't memorizing that list, because it shuffles every few months. It's knowing how to choose. Three rules:

1. Match the benchmark to your job. A coding leaderboard tells you nothing about how a model writes marketing copy or handles customer email.
2. Factor in price. The number-two model at a fraction of the cost is usually the smarter pick for high-volume work.
3. Test on your own tasks. Ten of your real prompts beat any leaderboard, every time.
