GPT-5.6 Sol: Specs, Access, Changes, and the Risks That Still Matter

OpenAI's current GPT-5.6 Sol model page lists a 1.05M context window, 128K max output, reasoning controls, and a time-sensitive API price card. Here is what those facts mean for API, Codex, and browser users.

All prompts and workflows
Agent workflow · API configurationSource reviewed

Design a verifiable multi-agent workflow with the Responses API

Separate judgment from deterministic processing, then combine programmatic tool calls, parallel subagents, and prompt-cache boundaries into a long-running workflow whose cost, latency, citations, and failures can be reviewed.

Prepare
user goal, tool schemas, agent responsibilities, cache boundaries, acceptance criteria
Runtime
OpenAI Responses API and a production agent harness; define tool calls and human checkpoints yourself

reasoning · speed-latencySource reviewed

Route ChatGPT tasks through Sol’s reasoning settings

Run the same task at faster and deeper reasoning settings: prefer speed for short questions, then increase reasoning for planning, research, writing, coding, and decisions; OpenAI’s 68% figure is an internal relative change, not public accuracy.

Prepare
task type, fixed acceptance criteria, speed and quality preference, client and date record
Runtime
ChatGPT web, mobile, or desktop client; do not infer Codex or API parameters

Coding · Agent workflowUnverified

Configure Codex for a million-token context and auto-compaction

The source shows config.toml and one-session CLI examples for the model ID, a 1,000,000-token context budget, and a 900,000-token compaction threshold; confirm client support and keep a rollback configuration before editing.

Prepare
Codex version, model ID, configuration backup, context target, read-only validation task
Runtime
Codex CLI; confirm client version, model support, and local configuration path

Coding · Agent workflowSource reviewed

Deliver code with prediction, planning, review, and verification

Split long-running coding into prediction, planning, implementation, adversarial review, and independent verification, checking the plan, tests, and stop conditions item by item; this is a commenter’s personal workflow, not Codex’s default configuration.

Prepare
repository, task goal, risk list, test commands, acceptance signals, stop conditions
Runtime
Codex, OpenCode, or a coding agent that can save plans and run tests; map stages to actual hooks or commands

OpenAI release note: Sol's official results on long-horizon, coding, and knowledge work

OpenAI reports Sol at 53.6 on Agents’ Last Exam, near Fable 5 on the Intelligence Index, and 80 on the Coding Agent Index, plus 92.2% on BrowseComp and 62.6% on OSWorld 2.0; these are dated vendor results.

Evidence

Boundary
Does not support independent reproduction, a universal cross-model ranking, or current product availability.
Artificial AnalysisIndependent measurement

Artificial Analysis: Sol's intelligence, coding-agent result, and cost per task

Artificial Analysis records Sol max at 59 on its Intelligence Index, about $1.04 per task, and 80 on its Coding Agent Index, with roughly 15,000 output tokens per task; models are paired with complete harnesses such as Codex.

Evidence
Independent measurement
Boundary
Does not support extrapolating 59, 80, or cost per task to other clients, live prices, or all tasks.
CodeRabbitIndependent measurement

CodeRabbit: Sol's trade-offs in long coding-agent runs and code review

CodeRabbit reports a 63.7% long-run coding pass rate for Sol with 20,968 average output tokens per completed task; review passed 69/99 actionable cases at 31.6% precision while producing 231 comments, combining recall gains with noise.

Evidence
Independent measurement
Boundary
Does not support general success or precision rates independent of CodeRabbit's harness.
