Alternatives to GPT-6 Sol

OpenAI LMArena 1395.4 $4.00/M on a balanced workload prices as of 2026-10-06

2 models are higher-scoring or cheaper, with neither dimension worse.

Of the 144 models carrying both an independent score and a published price at the same delivery mode, 71 score at least as high as GPT-6 Sol and cost no more under at least one listed workload, with at least one of those dimensions improved. 69 of them cost less; the rest match the price and have a higher score. 2 match or beat its recorded context, maximum output, input modes, tool use and extended reasoning. 69 have a recorded capability loss, named on every row.

Dominance is not a property of a model. It is a property of a model, a capability lens and a workload, and all three are named on every row. Scores are LMArena Elo, used under CC BY 4.0 from the official dataset; prices are blended per million tokens. A higher score is not a drop-in replacement.

This page is built only while a candidate improves score or price without worsening the other under a listed workload. When that comparison no longer holds, it is not generated.

Where it holds

Workload	GPT-6 Sol $/M	Recorded capabilities preserved	Recorded capability losses
Balanced	$4.00	2	69
Summarise	$1.89	2	69
Chat	$4.66	2	68
Code gen	$6.66	2	68
Agentic	$2.13	2	67

Workload mixes are defined on the methodology page. Cached input is priced at the cached rate, and reasoning tokens at the worse of the reasoning and output rates.

What you would be replacing

Intelligence	1395.4
Context window	1M
Max output	128K
Input modes	file, image, text
Tool use	yes
Extended reasoning	yes

Preserving recorded capabilities requires matching or beating these fields. Full record for GPT-6 Sol, or check GPT-6 Sol against the whole catalogue.

Recorded capabilities preserved 2

Each option has a higher score or a lower price, with neither dimension worse under the listed workloads. It matches or beats GPT-6 Sol on recorded context, maximum output, input modes, tool use and extended reasoning.

What this compares, and what it leaves out

Quality is LMArena Elo, used under CC BY 4.0 from the official dataset. The 95% confidence interval on a difference between two scores is about ±10.47 points, so a gap smaller than that is marked tie rather than an improvement — see significance bands.
204 further models at this delivery mode carry a price but no independent score. They are absent from the comparison in both directions — unrated is not a zero, and an unmeasured model is neither an alternative nor a worse buy.
Retired models are never offered as an alternative, and a model only competes against its own delivery mode: batch trades latency for price, so it is not a like-for-like swap.
Nothing here measures latency, throughput, rate limits or how a model behaves on your prompts. Two models with the same index score are not interchangeable.
Models with no higher-scoring or cheaper alternative that is no worse on the other axis are on the value frontier. Models with such an alternative are listed here.
