Claude Sonnet emerges as the best AI for coding

Claude Sonnet has pushed ChatGPT and Gemini into the background in the demanding world of code assistance. Programmers who demand few errors, smooth corrections and internal execution have found their best ally in this Anthropic model. But not all workflows are equal: the combination of IDE and extensions makes the difference between a useful tool and a frustration machine.

The average user looks for an AI that "makes few mistakes", "accepts corrections and incorporates them", "runs the code internally before delivering it" and "explains what each line does". Those four pillars support real productivity. Anyone who has tried the free versions knows that ChatGPT tends to promise and fail; Gemini fails to convince; Grok comes second. The paid experience with Claude Sonnet, both in versions 4.6 and 5, takes the applause.

The debate doesn't stop at the base model. Setups appear such as the Antrigravity IDE with the Claude Code extension and specific skills (caveman, ponytail, headroomlabs) that automate complex tasks. Others bet on Claude Code directly in the terminal, or on Sonnet plus any IDE accompanied by GitHub Spec Kit to avoid repetitive prompts. The flexibility is enormous, but the cost is minimal: Claude Pro costs 10 euros a month. The free alternative GPT-5.6 doesn't quite work out: "it says everything is fine until it fails and doesn't correct", according to shared experience.

Claude Sonnet's dominance in assisted programming seems solid, but the model race moves fast. GPT-5.6 and Gemini's promises could close the gap. For now, whoever invests 10 euros a month gets a digital partner that writes, debugs and explains with hardly any supervision. The question is not whether AI codes better than a human, but which one does it with fewer headaches.
