Background
Claude 3.5 Sonnet (mid-2025) was widely regarded as the best capability-per-dollar model of the year: near-flagship intelligence at a lower price tier. For cross-border teams, SaaS founders, and content operators, it marked the point where AI moved from experimentation to daily production.
Key points
- Coding & agents: much better completion of long, multi-step tasks; became the mainstream choice for agent workflows.
- Writing & localization: strong multilingual output, great for bilingual content restructuring.
- Artifacts: the workspace extended from chat to docs, code, and visuals.
Engineering takeaways
- Agentification is not a switch: context management, tool use, and error recovery matter as much as model capability.
- Run the workflow on a mid-tier model first; upgrade to flagship only where needed.
