Notes
- Intelligence Index = Artificial Analysis Intelligence Index v4.0 (composite of 9 evals including GDPval-AA, Terminal-Bench, SciCode, AA-Omniscience). Higher is better. Scores reflect max-effort / adaptive reasoning mode where applicable.
- Hallucination Rate = AA-Omniscience Hallucination Rate (%). Lower is better. Tier labels: low (<30%), mid (30–54%), high (≥55%). Measures how often the model answers incorrectly when it should have refused or admitted uncertainty. See artificialanalysis.ai/evaluations/omniscience.
- Coding Agent Index = Artificial Analysis Coding Agent Index v1.1 — composite pass@1 across DeepSWE, Terminal-Bench v2, and SWE-Atlas-QnA for model+harness pairs. Higher is better. Scores shown use the best published harness per model; "—" means AA has not yet evaluated that model. See artificialanalysis.ai/agents/coding-agents.
- Pricing reflects standard (non-cached) token rates. Cached input tokens are typically ~92% cheaper.
- Gemini 3.1 Pro Preview pricing doubles to $4/$18 per 1M above 200K tokens per prompt.
- Claude Opus 4.7 and Claude Sonnet 4.6 both support a 1M token context window with 128K max output tokens.
- As of July 2026, GPT-5.5 (xhigh) and Claude Fable 5 are tied at the top of the AA Index at 60, with GPT-5.6 Sol close behind at 59.
- Claude Fable 5 and Claude Mythos 5 (Fable 5's unrestricted-cyber/bio counterpart) launched June 9, 2026. Access was suspended June 12–July 1, 2026 for U.S. export-control compliance; current pricing/scores reflect the restored, generally available model.
- GPT-5.6 ships as three durable capability tiers rather than a single model: Sol (flagship), Terra (balanced/everyday), and Luna (fastest/cheapest). AA-Omni scores for the GPT-5.6 family were not available from Artificial Analysis at time of writing.
- Grok 4.5 (high) is xAI's first release since its SpaceXAI rebrand and IPO; it's notably cost-efficient per completed task despite a high measured AA-Omniscience hallucination rate (~54%), so it's a strong pick on price but needs verification for high-stakes factual work. AA-Omni score not yet published.
- Open-weight models (self-hostable): Kimi K3 (weights releasing July 27, 2026), Kimi K2.6, MiMo-V2.5-Pro, GLM 5.1, DeepSeek V4 Pro, DeepSeek V4 Flash, Hy3-preview, Nemotron 3 Super.
- DeepSeek V4 Pro and V4 Flash OpenRouter pricing shown; first-party DeepSeek API pricing differs ($1.74/$3.48 for Pro, $0.14/$0.28 for Flash).
- Nemotron 3 Super is also available free-tier on OpenRouter (rate-limited).
