Anthropic Claude Sonnet 5 vs Sonnet 4.6 vs Opus 4.8: Agentic Coding Benchmarks, API Pricing, and Cost-Performance Tradeoffs Compared
Why it matters
Anthropic's new Sonnet model challenges the performance/cost hierarchy in LLMs, forcing teams to reconsider which tier they're paying for—critical for engineering leaders managing inference budgets.
Key signals
- Claude Sonnet 5 performance on agentic coding benchmarks now competitive with Opus 4.8
- Sonnet 5 offered at lower token pricing than Opus 4.8
- Comparison includes cost-performance tradeoff analysis across three model tiers
- Focus on agentic coding as evaluation metric
The hook
Claude Sonnet 5 just closed the gap to Opus on agentic coding. At half the token cost.
Anthropic's Claude Sonnet 5 narrows the gap to Opus 4.8 on agentic coding, at cheaper Sonnet token pricing.
