GPT-6.1 Sol vs GPT-6 Sol

Updated November 13, 2026. Rank says GPT-6.1 Sol is ahead. Price, access, and your workload can each overturn that. Public scores include evidence status and uncertainty. This is a same-family comparison, so migration details appear when the source data supports them.

Decision reading

GPT-6.1 Sol has the higher public score estimate, 84.63 versus 77.44, but the 90% score intervals overlap. Treat that as a lead, not a settled winner. 22 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

    GPT-6.1 Sol

    GPT-6.1 Sol has the higher public coding point estimate, 73.4 to 67.3, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Which one for a specific job

Choose a job from the LLM Selector's task catalog to see the category row it rests on, under the same basis rules as the table below. A directional row stays directional; choosing a job never creates a winner.

GPT-6.1 Sol has the higher coding point estimate. Conditional score ranges do not establish rank confidence.

Or describe your own job

The LLM Selector reads what you need a model for and returns a shortlist, ranked in the same order the job pages publish.

Describe the task and constraints. This selector recommends models; it cannot carry out the task or access your files and accounts.

We keep what you type here, drafts included, for 180 days, and after that only the job and requirements read from it. Nothing is tied to your IP address or account. Leave out names and other personal details. Privacy

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

1 category rests on Estimated evidence or different evidence sets. Those rows remain visible for coverage context but do not name a winner.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

Bars run 0–100 on each benchmark’s normalized display scale

Category results, on a stated basis

Each row shows the public-lane category score for both models: the BenchAlign v5.8 lane for agentic, coding, reasoning, multimodal, and knowledge, and the weighted public rows elsewhere, with the same rank each model page reports. A row is like-for-like only when both scores rest on Supported evidence or the same weighted set. Directional and not-comparable rows remain visible, but they never receive a winner.

Ranks count the models scored in each category’s lane, so the agentic, coding, reasoning, multimodal, and knowledge denominators (BenchAlign v5.8) differ from the provisional-lane categories. Unranked scores sit on the provisional lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.

Questions

Which is better, GPT-6.1 Sol or GPT-6 Sol?

GPT-6.1 Sol has the higher public score estimate, 84.63 versus 77.44, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, GPT-6.1 Sol or GPT-6 Sol?

GPT-6.1 Sol has the higher public coding point estimate, 73.4 to 67.3, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Which is better for agentic tasks, GPT-6.1 Sol or GPT-6 Sol?

GPT-6.1 Sol has the higher public agentic tasks point estimate, 65.7 to 65.1, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Which costs less, GPT-6.1 Sol or GPT-6 Sol?

For the stated presets, chat costs $0.007 on GPT-6.1 Sol and $0.007 on GPT-6 Sol; repository review costs $0.13 and $0.13; the cache-heavy agent loop costs $0.16 and $0.18. Costs use the listed standard API rates.

Which has the larger context window, GPT-6.1 Sol or GPT-6 Sol?

Both models list the same context window, 1.05M.
