GPT-6 Sol

A new workhorse route for difficult coding and agent tasks with a 1.05M context window. The specifications and price are concrete, but the launch performance claims are vendor-reported, so HubAI withholds a score until a same-work test measures accepted results and complete cost.

What we can verify

Supplier information and independent test results are separate. Check the linked product and pricing sources before purchase.

What an independent test needs to cover

Test output accuracy, retries, reviewer effort, data handling and total cost using the pilot below. No completion date is scheduled; a score will require a published method and results.

EDITOR VERDICT

WHAT IT IS

GPT-6 Sol, explained.

GPT-6 Sol is designed for complex coding, agentic and professional tasks where higher accepted-task quality can justify a premium over a volume model. HubAI treats it as a workflow purchase rather than a novelty: the relevant question is whether it produces an acceptable result repeatedly, with controls your team can understand and a cost that remains predictable after the trial ends.

Verify the data-use, retention, model-improvement, regional-processing and administrator terms for the exact OpenAI API, ChatGPT Work, Codex or GitHub Copilot route. OpenAI lists EU data residency only for the standard API tier; product surfaces and third-party routes have separate controls.

DEPLOYMENT

gpt-6-sol through the OpenAI API, with gradual rollout in ChatGPT Work, Codex and eligible GitHub Copilot plans. The API page lists a 1,050,000-token context window, 128K maximum output and reasoning from none through max. Inputs above 272K use higher full-request rates.

STRENGTHS

What earns its shortlist place.

+01

Published 1,050,000-token context window and 128K maximum output

Why it matters: accelerates repository navigation.

+02

Reasoning controls from none through max, with text and image input

Why it matters: removes repetitive implementation work.

+03

Available through API, ChatGPT Work, Codex and eligible GitHub Copilot plans

Why it matters: keeps explanation and change close together.

LIMITATIONS

What can break the business case.

−01

Launch benchmarks, factuality and safety comparisons are provider-reported

Buyer impact: can create plausible but fragile code.

−02

Inputs above 272K reprice the full request at higher rates

Buyer impact: moves effort into review and testing.

−03

Tools, retries, infrastructure and reviewer time can dominate complete task cost

Buyer impact: requires policy controls for private repositories.

Cost reality

The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.

PRICING DECODER

Budget for the result, not the plan badge.

Published structure: $2/1M input, $0.20/1M cached input, $2.50/1M cache write and $10/1M output at standard API rates; requests above 272K input use higher rates · Profile record only; separate pricing check not recorded: 23 September 2026. USD list price; UK price/VAT to confirm.
Free or trial route: Metered API access; gradual availability in ChatGPT Work and Codex for eligible paid, Business, Enterprise and Edu plans, plus selected paid GitHub Copilot plans
Primary cost driver: seat price, premium requests, agent runs and reviewer correction time
Budget test: Record the total cost, attempts and human correction needed to produce ten accepted results.

Separate pricing check date: not recorded. Profile review: 23 September 2026. Confirm live price, VAT, region, usage rights and cancellation terms with the vendor before purchase.

Where GPT-6 Sol earns its place.

Build and test a long-running coding agent

Test this job with your own inputs and judge the finished result—not the first draft.

Run multi-file refactoring with deterministic tool calls

Test this job with your own inputs and judge the finished result—not the first draft.

Evaluate a complex enterprise workflow against cost and latency

Test this job with your own inputs and judge the finished result—not the first draft.

A safer four-step trial

Start with one narrow job that matches GPT-6 Sol's strongest use case.
Prepare approved source material, examples and a clear acceptance standard.
Run three realistic tasks and record attempts, correction time and export quality.
Keep human approval before publishing, sending or acting on the result.

READY-TO-USE PROMPTS

Start with a better brief.

Act as a specialist in model ai. Ask me three questions before creating the first draft. The outcome I need is: [describe outcome].

Create two approaches for [task]. Use this audience: [audience]. Respect these constraints: [constraints]. Explain the trade-off between the two approaches.

Review this output against accuracy, tone, privacy, cost and usability. List the changes required before a person should approve it.

RISK & GOVERNANCE

What to check before adoption.

Do not place confidential, personal or rights-restricted material into GPT-6 Sol until your organisation has reviewed its current terms, retention settings and account controls. AI output can be plausible and still wrong; regulated, financial, legal and employment decisions require qualified human review.
