Gemini 4 Argon versus Opus 5.5 and GPT-6 Astra across coding, terminal agents and automation benchmarks—and how to compare them in your own workflow.

Haiku wins on short-request pricing; Flash-Lite is cheaper for long inputs. Current rates, independent benchmarks, and practical choices for automation and business agents.

GPT-5.6 is a routing family, not a universal default. API pricing is now official: promotional Sol is $4/$20, Terra $2/$12, and Luna $0.20/$1.20 per million tokens.

Datacurve published DeepSWE on May 26, 2026: a benchmark for long-horizon coding agents. The important part is not just the leaderboard, but the measurement method: original tasks, larger repository changes, and behavioral verification.

Google released Gemini 3.5 Flash at I/O 2026. Independent benchmarks show excellent speed and agentic performance, but also a higher cost than the older Flash model and weaker spots in hard coding, instruction following and sensitive decisions.
