---

OpenAI's GPT-5.6 Terra — the balanced middle tier of the July 2026 GPT-5.6 preview, priced at half of GPT-5.5 ($2.50/$15 per 1M tokens). OpenAI pitches it as 5.5-competitive for everyday work; our matrix agrees.

**Score:** 5/5 benchmarks passed · **Cost across the matrix:** $0.392

## Strengths
- Perfect score with the tightest tool budget of the run: 2-4 calls per benchmark, 13 total.
- Cheapest Sales pass in the matrix: two tool calls and $0.023 on the Crunchbase brief, taking the crown from Gemini 3 Flash.
- Fastest cell of the whole run — the Sales brief completed in 9 seconds.

## Watch-outs
- The CX benchmark ate $0.20 — over half its matrix total. Open-ended review mining makes it think; budget for that on ambiguous tasks.
- Preview pricing. The $0.39 total assumes the half-of-5.5 preview rate holds at GA.
- Same short-horizon caveats as the rest of the matrix: 2-9 tool-call tasks, no adversarial inputs, no multi-hour chains.
