Claude 3.5 Sonnet is Anthropic's mid-cycle flagship model, balancing strong reasoning, coding, and instruction-following with a 200K context window. It sits between Haiku and Opus in Anthropic's lineup, offering near-flagship quality at a lower cost than top-tier models.
Verdict
One of the best models for coding and complex instruction-following, but its premium pricing demands premium use cases.

Pricing at $6 input / $30 output per million tokens is significantly higher than GPT-4o ($2.50/$10). Best accessed via Anthropic API or Amazon Bedrock. Claude 3.5 Sonnet (October 2024 version) supersedes the June 2024 release with improved performance.
Claude Opus 4.7 moved into premium coding recommendations
Claude Opus 4.7 now leads premium coding recommendations because it has the strongest current public SWE-Bench Pro score among generally available models.
Claude Opus 4.7 is best for highest-ceiling coding, agentic workflows, and deep research. It is a strong fit when that workflow matters more than the tradeoffs around premium pricing and deliberate speed.
When should I avoid Claude Opus 4.7?
You need cheaper high-volume throughput, image generation, or a workflow that must stay inside OpenAI tooling.
What is a cheaper alternative to Claude Opus 4.7?
Mistral: Mistral Nemo is the lower-cost option to compare first when you want a similar workflow fit with less token spend.
What is a faster alternative to Claude Opus 4.7?
