Claude Opus 4.8
Best-in-class for complex multi-step agentic workflows, long-horizon planning, and large codebase refactors. Strong instruction-following on ambiguous, open-ended tasks.
Highest per-token cost in the catalog and noticeably higher latency — reserve for tasks that genuinely need top-tier reasoning rather than routine completions.
Grok 4.3
Strong real-time knowledge via X/Twitter integration and competitive general reasoning at a lower price than other flagship models.
Smaller third-party ecosystem and fewer enterprise compliance certifications than OpenAI/Anthropic/Google offerings.
