For blog writing, Claude Sonnet 4.6 (Anthropic) is our pick. Best daily driver for coding and writing — the model most developers actually reach for. It costs $3/1M input and $15/1M output tokens, with a 1M-token context window — enough headroom for all but the largest blog writing jobs. Claude 4 Haiku is the closest alternative if it doesn't fit your setup.
Because the work it is built for overlaps closely with blog writing: daily coding in Cursor — debugging, refactoring, and feature implementation and drafting polished client reports, strategy memos, and long-form editorial content. The best all-around model for most developers and writers. Strong SWE-bench, excellent writing, 1M context — all at $3/1M input. Hard to beat as a daily driver.
On a moderate month — 10M input and 2M output tokens — Claude Sonnet 4.6 runs about $60.00 at list price, with no batch or caching discounts applied, so treat that as a ceiling. Claude 4 Haiku is the cheaper route at roughly $16.00 for the same volume, if blog writing is high-volume enough for price to lead the decision.
Claude Opus 4.7 has a higher current premium coding ceiling. GPT-5.5 or GPT-5.4 are better picks when OpenAI computer-use workflows are the priority. Avoid it if you specifically need desktop-control capabilities (GPT-5.5/GPT-5.4) or the absolute highest coding ceiling (Opus 4.7). None of that rules it out for blog writing on its own — but if one of those limits maps onto how you actually work, take the alternative on this page seriously rather than defaulting to the top pick.
Claude 4 Haiku at $0.8/1M input is the budget option here. Best low-cost writing option for fast-moving content teams. Expect a quality step down on the hardest cases — the usual pattern is to route routine blog writing volume to Claude 4 Haiku and keep Claude Sonnet 4.6 for the work where a wrong answer is expensive.
Claude 4 Haiku, rated very fast against Claude Sonnet 4.6's balanced. Speed matters most for interactive and high-volume work; if your blog writing runs in the background, the slower and more capable model is usually the better trade.
