SCORING METHODOLOGY
PROVISIONAL CALIBRATION per /NM310-A1 (2026-09-07) — 1 BAND / 3 BAND-COMPOSITE / 15 INHERITED-PROVISIONAL / 1 PROXY; re-calibrate when per-dimension evals land. Flagship of the GPT-5.6 family (preview 2026-06-26, GA 2026-07-09). Naming system: number = generation, Sol/Terra/Luna = durable capability tiers. Pricing $5/$30 per M in/out (long-context: $10/$45 above threshold; cache writes 1.25x, cache reads -90%). Context ~1M tokens (docs; the circulated 1.5M figure was wrong), 128K max output. Model ID gpt-5.6-sol; bare gpt-5.6 alias routes here. Reasoning modes incl. max + ultra (parallel sub-agents); Sol Ultra = high-compute mode, not a separate SKU. Sol Pro exposed via OpenRouter/ChatGPT Pro. Vendor-reported leads: Agents' Last Exam (~54% xhigh), AA Coding Index (80), Terminal-Bench 2.1 (Ultra 91.9%), ARC-AGI-3 (~8%), OSWorld w/ 85% fewer output tokens than Opus 4.8. Trails Claude on SWE-Bench Pro, GDPval ELO, AAII, SimpleBench (Sol Pro 71.7% vs Fable ~82%). UK AISI found universal jailbreaks within hours at launch (since mitigated per OpenAI). Cerebras serving at up to ~750 tok/s announced for July. US govt requested limited preview before GA. PROVENANCE (-A1 lanes M1/M1b, per-dim): Planning and Execution [BAND:GPT-5.6 Sol (Ultra) — Terminal-Bench 2.1 (2026-07) 91.9]; Reasoning + Bulk Apperception [BAND-COMPOSITE:AA Intelligence Index — GPT-5.6 Sol (max) — 2026-07 59]; Code Generation [BAND-COMPOSITE:AA Coding Agent Index — GPT-5.6 Sol (max) — 2026-07 80]; Cost Efficiency [PROXY:AA $11.25/M blended]; all remaining 15 dimensions [INHERITED-PROVISIONAL:gpt-5-5]. Supersedes the 2026-09-06 header, whose counts (1 BAND / 18 INHERITED / 1 PROXY) predated the Reasoning and Code Generation composite bands written on 2026-09-07.
