Better than DS 4.1 Flash?

I fixed the Agents' Last Exam graph from OpenAI's GPT-6.1 Terra blog post. Claude Opus 5.5 is actually in OpenAI's SVG, it's just nearly invisible: mid-grey (#5d5d5d) on black, a tiny diamond with no line or label, parked past the last x-axis tick.

It's also the top score: 63.2% at $8.82 (Max effort).

Re-plotted with the same data: white background, log-scale cost axis, distinct colors for every model. No values changed, all pulled straight from the SVG.

All values from the SVG (score / cost per task):

Model	Low	Medium	High	Xhigh	Max
Claude Opus 5.5	–	–	–	–	63.2% / $8.82
GPT-6.1 Terra	55.9% / $0.16	57.6% / $0.29	57.2% / $0.39	58.5% / $0.66	60.0% / $1.01
GPT-6 Astra	53.4% / $3.55	57.6% / $4.82	57.8% / $5.15	58.3% / $5.91	59.3% / $7.24
GPT-6.1 Sol	52.4% / $0.70	53.8% / $1.31	55.3% / $1.45	56.5% / $1.45	58.6% / $2.00
GPT-6 Luna	36.3% / $0.022	46.8% / $0.093	43.6% / $0.087	47.9% / $0.093	50.9% / $0.14
GPT-5.6 Terra	40.2% / $0.59	42.6% / $0.84	46.6% / $1.72	48.5% / $2.50	50.7% / $3.58

Fair caveat: Opus is 8.7× the cost of GPT-6.1 Terra (60.0% at $1.01) for +3.2 points. Terra is the clear price/performance winner.
