Specifications
AI Evaluation
Anthropic reliability at commodity prices. The right engine for classification, extraction and routing tiers where a frontier model would be waste - and the wrong one for anything hard.
Pros
- Anthropic safety profile at $0.24/task
- Simple, cheap, predictable
- Strong value score (125) for a closed model
Cons
- Intelligence Index 30 - commodity tier
- 200k context is small for 2026
- No coding-agent benchmark presence
Related Tools
Claude Opus 4.8
Claude Opus 4.8 is Anthropic's June 2026 flagship model, succeeding Opus 4.7. It posts a headline score of 81 on the hardest agentic coding and reasoning suites, holds long-horizon tool-use plans together across far more steps, and is notably more candid about its own uncertainty - refusing to fabricate rather than confidently pressing on. It is the default choice for serious agentic and software-engineering workloads.
Claude Fable 5
Claude Fable 5 is Anthropic's most intelligent generally available model and the first of its Mythos-class tier, positioned above Opus. It tops the Artificial Analysis Intelligence Index at 60, leads SWE-bench Pro at 80.3%, and dominates knowledge-work benchmarks on substance - at $2.75 per measured task, the highest in the field. It returned to sale on 1 July 2026 after a fortnight-long US export-control suspension.
Claude Sonnet 5
Claude Sonnet 5 is Anthropic's mid-size default, released 30 June 2026 with a 1M-token context window as standard. It scores 53 on the Intelligence Index - three points off Opus 4.8 - and actually edges the flagship on GDPval knowledge work, at roughly half the per-token cost, with introductory $2/$10 pricing until 31 August 2026.
