OpenAI GPT-6 Family · Sol 1.1 · DevDay September 29, 2026
20 free GPT-6.1 Sol prompts for agentic coding, multi-agent orchestration, long-context analysis, and enterprise automation. OpenAI's upgraded Sol model — near-Astra performance at 1/5 the cost. No signup.
This page gives you 20 copy-paste prompts built for GPT-6.1 Sol — OpenAI's upgraded Sol-tier model, released at DevDay on September 29, 2026. GPT-6.1 Sol improves on GPT-6 Sol with meaningfully better agentic coding performance: +6.4 points on SWE benchmarks, near-parity with GPT-6 Astra on desktop automation, and beta multi-agent support in the Responses API — at the same price as GPT-6 Sol ($2/$10 per MTok). It is available in ChatGPT Work, Codex, and the OpenAI API.
The prompts here are structured for GPT-6.1 Sol's specific strengths: agentic workflows that benefit from multi-agent orchestration, coding tasks that demand near-Astra depth without Astra's cost, and long-context analysis using the 1,050,000-token context window. Each prompt includes bracketed placeholders — fill them in and paste directly into ChatGPT Work, Codex, or the API.
Software engineering benchmark improvement over GPT-6 Sol
Near-Astra performance on DeepSWE v1.1 at a fraction of the cost
Orchestrate sub-agents via the Responses API — new in 6.1
Reduced cached-input pricing — efficient for long-running agents
Built for agentic coding, multi-agent workflows, and long-context tasks. Works on GPT-6.1 Sol, GPT-6 Sol, and Astra.
Design and execute a multi-agent workflow for the following task. You are the orchestrator agent. Task: [describe the end goal in one sentence] Available sub-agents: [list their capabilities — e.g. code execution, web search, file access, API calls, database query] Constraints: [time budget, auth scope, off-limits systems, output format] Successful completion means: [define the exact state that confirms the task is done] As orchestrator: 1. Decompose the task into the minimum number of sub-agent calls needed (no redundant calls) 2. Specify each call: AGENT → INPUT → EXPECTED OUTPUT → NEXT STEP OR BRANCH 3. Identify the dependencies — which calls must complete before others can start (parallelise where safe) 4. Define the 3 most likely failure modes and the recovery action for each 5. Write the verification step: how you confirm the final output is correct, not just complete Return the orchestration plan as a numbered DAG with explicit branch logic.
Perform a deep code review on the following code. Match the depth of a senior engineer with a security background. Language/framework: [specify] PR description or change intent: [what this change is supposed to do] Code diff or full files: ``` [paste the code] ``` Known risks or concerns: [anything the team already suspects] Review dimensions (cover all, don't skip): 1. CORRECTNESS — logic errors that produce wrong output in production. Cite the specific line and the exact failure scenario. 2. SECURITY — injection, auth bypass, secrets exposure, SSRF, insecure deserialization, rate-limit bypass. Each finding: severity (CRITICAL/HIGH/MEDIUM), line, exploit path, specific fix. 3. PERFORMANCE — O(n²) or worse, N+1 queries, blocking I/O in hot paths, unbounded memory growth. 4. AGENT SAFETY — if this code runs in an agent: prompt injection vectors, tool call boundaries, unintended side effects, missing confirmation gates. 5. TEST GAPS — the 3 inputs most likely to expose a bug, with the expected behaviour and why it won't be caught without a test. End with: SHIP / SHIP WITH CHANGES / DO NOT SHIP and a one-sentence rationale.
Write a complete agentic task specification that a coding agent (GPT-6.1 Sol in Codex) can execute end-to-end without human clarification. Task goal: [describe the software change or feature to implement] Repository context: [language, framework, relevant file paths, coding conventions] Acceptance criteria: [what must be true for the task to be complete — write as testable assertions] Out of scope: [explicitly list what the agent must NOT change] Available tools: [file read/write, shell execution, test runner, linter, git] Specification must include: 1. STARTING STATE — what the agent reads first and why 2. IMPLEMENTATION STEPS — numbered, each with: action, file(s) affected, validation check 3. SELF-VERIFICATION — the exact commands to run (tests, lint, typecheck) before declaring success 4. ROLLBACK PLAN — how the agent restores the original state if a step fails mid-way 5. EDGE CASES — the 3 scenarios the implementation must handle that aren't obvious from the goal statement
Debug the following failing test or broken behaviour using a structured root-cause process. Do not guess — diagnose before proposing fixes. Language/framework: [specify] Failing test or error: ``` [paste the exact test, error message, or stack trace] ``` Relevant code: ``` [paste the code under test and any relevant helpers] ``` Environment details: [OS, runtime version, relevant env vars or config] What I've already tried: [list any steps already taken] Process: 1. HYPOTHESIS RANKING — list the top 3 root causes by probability, with your confidence percentage and the evidence for each 2. DIAGNOSTIC STEPS — for each hypothesis: the exact command or code change that would confirm or rule it out (no destructive changes yet) 3. ROOT CAUSE — after diagnosis: the specific line(s) and the mechanism of the failure 4. FIX — the minimal change that resolves the root cause (show the diff) 5. REGRESSION TEST — the new test case that would catch this failure in future 6. SIMILAR RISKS — 2 other places in the codebase where the same pattern could cause the same failure
Design an enterprise automation workflow for the following recurring process. Process: [describe the current manual process — steps, stakeholders, frequency, systems involved] Trigger: [what initiates this process — a schedule, an event, an email, a form submission?] Enterprise tools in use: [Salesforce / Jira / Confluence / Slack / SAP / ServiceNow / other — list all] Compliance requirements: [audit trail, approval gates, data residency, access controls] Error budget: [can errors be caught and corrected, or must this be zero-failure?] Deliver: 1. WORKFLOW DIAGRAM (text-based): each step as [STEP] → [SYSTEM/AGENT] → [OUTPUT] → [NEXT STEP or BRANCH CONDITION] 2. HUMAN-IN-THE-LOOP GATES — exactly where a human must review or approve before the workflow continues 3. AUDIT TRAIL — what is logged at each step, where, and in what format 4. FAILURE HANDLING — for each gate: what triggers escalation, who is notified, and what the SLA is 5. ROI ESTIMATE — hours of manual effort replaced per week, and the single highest-risk step that still needs a human
Plan a migration of the following codebase from its current architecture to the target architecture. Produce a phased plan an engineering team can execute. Current architecture: [describe — monolith / modular monolith / microservices, language, frameworks, databases] Target architecture: [describe the goal state and why it's being pursued] Critical constraints: [zero downtime, data integrity, rollback capability, team size, timeline budget] Known risks: [anything the team already knows is fragile or tightly coupled] Key codebase files or modules: [paste relevant architecture docs, key files, or dependency lists] Migration plan: 1. PHASE 0 — PREPARATION (no behaviour changes — tests, interfaces, seams) 2. PHASE 1 — STRANGLER FIG / PARALLEL RUN (incremental replacement with traffic shadowing) 3. PHASE 2 — CUTOVER (switchover strategy, rollback gate) 4. PHASE 3 — CLEANUP (remove old code, update documentation) For each phase: duration estimate, team roles, the go/no-go criteria, and the rollback procedure.

Review the following pull request as if you were an orchestrating senior engineer running multiple specialist checks in parallel. PR title and description: [paste the PR title, description, and any linked issue] Code diff: ``` [paste the full diff] ``` Run all of these checks and report findings in a single structured review: CHECK 1 — CORRECTNESS: Logic errors. State each as: location → failure scenario → fix. CHECK 2 — SECURITY: Vulnerabilities. Each: severity → exploit path → fix. CHECK 3 — PERFORMANCE: Regressions. Each: location → impact → fix. CHECK 4 — TESTS: Coverage gaps. Each: scenario missing a test → recommended test. CHECK 5 — AGENT SAFETY: If this code runs in an agent context — injection vectors, unintended side effects.

How GPT-6.1 Sol compares for agentic coding and complex professional tasks.
| Model | Best For | Agentic Coding | Context | Cost |
|---|---|---|---|---|
| GPT-6.1 Sol ✓ New | Agentic coding, multi-agent orchestration, long-context | Near-Astra | 1.05M tokens | Medium |
| GPT-6 Sol | Complex coding, research synthesis, structured documents | Strong | 1.05M tokens | Medium |
| GPT-6 Astra | Frontier tasks, computer use, maximum reasoning depth | Maximum | 1M+ tokens | High |
| GPT-6 Luna | Everyday tasks, high-volume API, fast drafting | Basic | Standard | Low |
| Claude Fable 5.1 | Nuanced reasoning, coding, instruction adherence | High | Standard | Medium |
GPT-6.1 Sol is OpenAI's upgraded Sol-tier model, released at DevDay on September 29, 2026 — seven days after GPT-6 Sol. It improves on GPT-6 Sol with meaningfully better agentic coding (+6.4 points on SWE benchmarks), stronger multi-step agent performance (+3.0 points on the General agent profile), and beta multi-agent support in the Responses API. In side-by-side benchmarks, GPT-6.1 Sol reaches within 2 percentage points of GPT-6 Astra on OSWorld 2.0 desktop automation tasks — at roughly one-fifth of Astra's cost per task.
GPT-6.1 Sol is the agentic-focused upgrade to GPT-6 Sol: same price ($2/$10 per MTok), same context window (1.05M tokens), but measurably stronger on coding agents. It outperforms GPT-6 Sol by +6.4 points on software engineering benchmarks, +1.7 points on agentic coding specifically, and +3.0 points on the General agent profile. It also adds beta multi-agent orchestration support in the Responses API and reduces cached input pricing to $0.10/MTok, making it more cost-efficient for agents that re-use long context across many calls.
GPT-6.1 Sol is priced at $2.00 per million input tokens, $0.10 per million cached input tokens (reduced from the standard cached rate), and $10.00 per million output tokens via the OpenAI API. The reduced cached-input price is particularly valuable for agentic use cases where the same long system prompt or codebase context is reused across many calls — it makes GPT-6.1 Sol significantly more cost-efficient than GPT-6 Astra for sustained agent workflows. Check the OpenAI pricing page for the latest rates.
For most production coding agent workflows, GPT-6.1 Sol matches GPT-6 Astra's output quality while running at roughly one-fifth of the cost per task. On the DeepSWE v1.1 benchmark, GPT-6.1 Sol achieves parity with Astra. On OSWorld 2.0 desktop automation, it closes to within 2.1 percentage points of Astra. For the narrowest frontier tasks — novel security research, the most complex multi-file architectural redesigns, or tasks requiring maximum reasoning depth — Astra still holds the edge. For most real-world software engineering agents, GPT-6.1 Sol is the better economic choice.
GPT-6.1 Sol added beta multi-agent support in the OpenAI Responses API, allowing it to function as an orchestrator that spawns and coordinates sub-agents. In a multi-agent setup, GPT-6.1 Sol can decompose a complex task, route sub-tasks to specialised agents or tools, synthesise their results, and handle failures — all within a single orchestration loop. This is in beta as of September 2026 and is available to API users. It makes GPT-6.1 Sol the recommended model for building production-grade agentic workflows on the OpenAI platform.
GPT-6.1 Sol is available in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Education users, and via the OpenAI API. It was released on September 29, 2026 at OpenAI DevDay. In ChatGPT Work, it is the recommended model for complex coding and agentic tasks — one step above GPT-6 Sol in the model selector. In the API, it is available as a named model endpoint alongside GPT-6 Sol, Luna, and Astra.
