Lines connect measured and explicitly modeled effort points. Filled dots are measured by Artificial Analysis; hollow dots are formula-derived. Snapshot: (26 frontier rows re-probed, plus one deployed-product comparator).
Sol pricing refreshed. OpenAI lowered Sol to $4 input and $20 output per million tokens on August 21. The lower promotional price is available at least through November 21, 2026. All 26 frontier rows were re-probed so every cost remains on one current AA basis.
AI Health Export lens. Gemini 3.1 Flash-Lite remains as a single gray diamond because v2 currently uses it. The orange hollow-square line shows the entire Luna effort curve with Fast pricing. Fast is a per-request service tier, not a medium-only model, so every Luna point keeps its measured intelligence score and moves to exactly 2× its Standard cost. Luna medium therefore moves from $0.0116 to $0.0232/task. This is a pricing scenario, not a separate AA latency benchmark. Google Cloud billing and bulk prompt-test spend do not feed this axis.
| Model | Effort | Index | $/task | Point | Source / basis |

Configurations. OpenAI says max gives GPT-5.6 more
reasoning time than xhigh, while ultra coordinates four agents in parallel by default.
Ultra is a separate multi-agent mode without a directly comparable AA cost/task point, so it is not plotted.
The app ladder differs from the API ladder plotted here: the ChatGPT/Codex picker shows
Light · Medium · High · Extra High · Ultra for Sol and Terra, but only
Light · Medium · High · Extra High for Luna (no Ultra) — observed 2026-08-04. The names do not
correspond to the API's low…max, the app offers no "Max", and whether app "Ultra" maps to
API max is undocumented. Every rung plotted here is an API configuration measured by AA.
OpenAI cut Luna 80% ($1.00/$6.00 → $0.20/$1.20) and Terra 20%
($2.50/$15.00 → $2.00/$12.00) on 2026-07-30. On 2026-08-21, OpenAI also lowered
Sol to $4.00 input and $20.00 output per million tokens. Sol's price is promotional
and available at least through 2026-11-21.
Gemini 3.7 Flash is measured at low, medium, and high.
Grok 4.6 supports low, medium, high, and
xhigh reasoning effort, with high as the default. AA currently measures
only high, so Grok's other three rungs are visibly hollow M1 projections. xAI does not
document a max rung for Grok 4.6, so none is plotted.
Cost axis is AA Intelligence-Index cost per task, not coding-agent cost. Hollow points are modeled scenarios, not published measurements. To update, edit AA_SNAPSHOT and keep the companion Markdown in sync.
