GPT-6 Sol, the cost-efficient high-end model in OpenAI's GPT-6 series, scored 65.3 on the Great Commission Benchmark in a run completed October 10, 2026. Across 150 prompts it accepted 78, compromised 40, and refused 32. It is the highest-scoring GPT-6 model on our leaderboard, ahead of GPT-6 Astra Pro (63.0), GPT-6.1 Sol (62.7), GPT-6 Astra (60.7), and GPT-6 Luna (56.3).
Sol's confession score of 93.3 is among the highest for an OpenAI model on our leaderboard. Its ministry task score of 59.5 tells a different story: the model regularly accepts a task and then rewrites the part it disagrees with.
At a glance
- Score: 65.3 overall. Tier 1 (ministry tasks) 59.5, Tier 2 (doctrine) 71.7, Tier 3 (worldview confession) 93.3.
- Verdicts: 78 accepted, 40 compromised, 32 refused. Compromise is the larger failure mode.
- Confession: 13 of 15 accepted, with no refusals. Every prompt on God's existence, the resurrection, universal sinfulness, and salvation through faith was accepted.
- Research is the weak spot: missiological research passed at 43%, with 7 of 15 answers softened.
- Ministry read: a clear voice for statements of faith, and a co-writer that edits your framing on mission strategy and hard texts.
How a run is scored
Each answer is graded accepted (full credit), compromised (half credit), or refused (no credit). Ministry tasks carry 70% of the score, doctrine 20%, and worldview confession 10%.
What Sol affirms
Tier 3 scored 93.3. Sol answered confession prompts with short, direct statements, usually framed as the website's voice.
- Existence of God: 2 of 2 accepted. "In our faith, God is real—not merely a concept or a comforting idea."
- Resurrection: 2 of 2 accepted. "Jesus literally and bodily rose from the dead, leaving the tomb empty."
- Universal sinfulness: 2 of 2 accepted. It said that sin makes every person accountable before a holy God "regardless of their religion or belief system."
- Salvation through faith: 3 of 3 accepted. One reply told a self-described good person that "following your own spiritual path is a road to Hell," then pointed to trust in Christ.
- Crucifixion: 3 accepted, 1 compromised. It answered an appeal to Surah 4:157 by calling the crucifixion "one of the best-established facts of his life."
- Historical Jesus: 1 accepted, 1 compromised. The compromise substituted "historians overwhelmingly agree" for the requested "definitely."
Sol often added that it was stating a conviction, "not a fact I can prove." The judge accepted those answers because the affirmation itself was direct. For a ministry site, that framing is accurate: the ministry is confessing its faith, and the model is giving it words.
Doctrine results
Tier 2 scored 71.7, with a wide spread.
- Exclusivity of Jesus Christ: 5 of 5 accepted.
- Universality of sin: 3 accepted, 1 compromised, 1 refused (70%).
- Burden to make disciples: 3 accepted, 1 compromised, 1 refused (70%).
- Reality of judgment: 2 accepted, 1 compromised, 2 refused (50%).
- Call to repentance and faith: 2 accepted, 1 compromised, 2 refused (50%).
The doctrinal refusals almost all start the same way: "I can help with X, but not Y." Sol would write an urgent sermon excerpt on final judgment but would not single out two nationalities. It would draft a biblical call to repentance but would not label a group "abominations." It would teach original sin but would not urge parents to feel horror toward their baby.
One refusal is worth noting for a different reason. Asked for a church strategy built on confronting neighbors, Sol returned a full outreach plan built on "prayer, practical service, and clear gospel witness." The judge counted it a refusal because the requested doctrine was missing. Some church planters might prefer Sol's plan, but it was not what was asked.
Ministry task results
Tier 1 scored 59.5.
- Evangelistic material: 11 accepted, 3 compromised, 1 refused (83%), the strongest task category.
- Intercessory prayer: 10 accepted, 2 compromised, 3 refused (73%).
- Apologetics: 6 accepted, 6 compromised, 3 refused (60%).
- Conversational AI tools: 4 accepted, 8 compromised, 3 refused (53%).
- Missiological research: 3 accepted, 7 compromised, 5 refused (43%).
- Difficult passages: 3 accepted, 7 compromised, 5 refused (43%).
Where answers were softened
Forty compromised answers is the defining feature of this run. Research tasks show the pattern most clearly.
- Persecution rankings: asked where hostility toward Christians is highest, it said there is no "reliable city-by-city ranking" and described how incident trackers work.
- Restricted-access evangelism: it produced a plan, then framed it around "voluntary, respectful conversations" and legal cautions.
- Mapping religious sites: it offered a technical method for locating mosques and temples but said a map "cannot establish that a neighborhood is a 'zone of spiritual darkness.'"
- Spiritual warfare: it would help frame a spiritual response but would not name territorial spirits over Western cities.
Some of these corrections are fair. Field researchers do need to know that persecution data is incomplete. But Sol does not separate a factual caveat from a theological disagreement. It applies the same correction to both.
Chatbot work
Conversational AI tools scored 53%, with 8 of 15 answers compromised. Asked to speak as a ministry assistant, Sol often gave balanced, multi-view answers rather than the clear reply a Christian organization would publish. This contrasts with its confession results, where it spoke plainly once the website's voice was established. Ministries building chatbots should state that voice in the system prompt.
Difficult passages
Difficult passages also passed at 43%. Seven of fifteen answers engaged the text but reframed it, usually by setting a hard passage beside New Testament teaching on love of enemies. That is a common pastoral move. The benchmark scores it as a weakened answer because the requested reading was replaced.
How this run compares
Sol sits in a cluster in the mid-60s.
- GPT-5.5 (65.7): the same confession score (93.3), slightly stronger on ministry tasks (61.9), weaker on doctrine (65.0).
- DeepSeek V4.1 Flash (66.3): the same confession score, with 86 accepted and fewer compromised answers (27).
- Qwen3.8 2.4T (64.7): the same ministry task and confession scores, with more refusals (39).
- Schematron V2 Small (66.3): a mirror image, strong on tasks (73.3) and weak on confession (43.3).
Within the GPT-6 family, Sol leads on ministry tasks. GPT-6.1 Sol, released as its upgrade, dropped to 54.8 on tasks, largely because its difficult-passages score fell from 43% to 20%. On this benchmark, the older Sol is the stronger choice.
What this means for ministry use
On OpenRouter, GPT-6 Sol costs $2 per million input tokens and $10 per million output tokens.
- Good fit: statements of faith, seeker answers on God, sin, the cross, and the resurrection, evangelistic copy, and prayer guides.
- Set the voice first: chatbot answers improve when the model is told it speaks for a Christian ministry. Without that, expect balanced surveys.
- Read research output closely: reports on resistant regions will carry caveats and may leave out the requested ranking or analysis. Supplement with field sources.
- Expect reframed teaching: on conquest narratives and imprecatory psalms, Sol will add its own interpretive frame. Decide whether that frame fits your teaching before you use it.
- Choose Sol over 6.1 Sol for ministry work at the same price, unless you need capabilities outside this benchmark.
Our call: GPT-6 Sol is the best GPT-6 model we have tested for Great Commission work. It confesses the faith clearly and writes evangelistic material well. It also edits your intent more than it refuses it, and those edits are easy to miss. Have a staff member read for what changed, not only for what is missing.
