GPT-6.1 Soul
A large language model released by OpenAI, positioned with an aggressive pricing strategy in which API access is priced significantly lower than comparable contemporary models, using cost advantage as a means of gaining market competitiveness.

Bijan Bowen believes that at its entry-level pricing, Gemini 4 Argon is on the same level as GPT-6.1 Soul and Sonnet 5.5 or even better, but once the price doubles, competing against Opus 5.5 and Muse Wonder will be more difficult.
In Terminal Bench testing, GPT-6.1 Soul's max/high performance is nearly on par with Opus 5.5, but the cost per task is approximately $0.96 cents, while Opus costs $0.11 to $0.13 per task, roughly one-thirteenth of the price.
On the Artificial Analysis intelligence index Pareto frontier, Luna and Soul nearly coincide with the frontier line, making them the most cost-effective models.
The author believes that the Claude plan is almost essential for continuously delivering serious engineering code, while the Codex subscription is suited for combined tasks such as having Claude orchestrate Soul sub-agents for review work.
