Goldman Sachs Trend Driven Allocation Fund Investment Risks - Institutional [Member] - Goldman Sachs Trend Driven Allocation Fund	Dec. 31, 2025
Absence of Regulation Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Absence of Regulation Risk.  The Fund engages in over-the-counter ("OTC") transactions, which trade in a dealer network, rather than on an exchange. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges.
Asset Allocation Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Asset Allocation Risk.  The Fund’s allocations to the various asset classes may cause the Fund to underperform other funds with a similar investment objective.
Credit Default Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Credit/Default Risk.  An issuer or guarantor of fixed income securities or instruments held by the Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). These risks are heightened in market environments where interest rates are rising as well as in connection with the Fund’s investments in non-investment grade fixed income securities.
Derivatives Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Derivatives Risk. The Fund's use of options, forwards, interest rate futures, interest rate swaps, credit default swaps and other derivative instruments may result in losses, including due to adverse market movements. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other assets and instruments, may increase market exposure and be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of the underlying assets or instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.
Expenses Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Expenses Risk. By investing in pooled investment vehicles (including investment companies and ETFs), partnerships and real estate investment trusts (“REITs”) indirectly through the Fund, the investor will incur not only a proportionate share of the expenses of the pooled investment vehicles, partnerships and REITs held by the Fund (including operating costs and investment management fees), but also the expenses of the Fund.
Foreign Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation; less public information; less stringent investor protections; less stringent accounting, corporate governance, financial reporting and disclosure standards; and less economic, political and social stability in the countries in which the Fund invests. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is impossible to predict. For example, the imposition of sanctions and other similar measures could, among other things, cause a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact the Fund’s liquidity and performance. Foreign risk also involves the risk of negative foreign currency exchange rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.
Geographic Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Geographic Risk. If the Fund focuses its investments in issuers located in a particular country or geographic region, it will subject the Fund, to a greater extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions and developments that may be particular to that country or region, such as: adverse securities markets; adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other developments; or natural disasters.
Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Interest Rate Risk. When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities will normally have more price volatility because of this risk than short-term fixed income securities or instruments. Changing interest rates may have unpredictable effects on the markets, may result in heightened market volatility and may detract from Fund performance. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Funds with longer average portfolio durations will generally be more sensitive to changes in interest rates than funds with a shorter average portfolio duration. Fluctuations in interest rates may also affect the yield and liquidity of fixed income securities and instruments held by the Fund.
Investing in the Underlying Funds [Member]
Prospectus [Line Items]
Risk [Text Block]	Investing in the Underlying Funds. The investments of the Fund are concentrated in one or more underlying funds including ETFs and other registered investment companies (“Underlying Funds”) subject to limitations and/or conditions prescribed by the Investment Company Act of 1940, as amended (the “Investment Company Act”), or rules, regulations or exemptive relief thereunder. The Fund’s investment performance is directly related to the investment performance of the Underlying Funds it holds. The Fund is subject to the risk factors associated with the investments of the Underlying Funds and will be affected by the investment policies and practices of the Underlying Funds in direct proportion to the amount of assets allocated to each. A strategy used by the Underlying Funds may fail to produce the intended results. If the Fund has a relative concentration of its portfolio in a single Underlying Fund, it may be more susceptible to adverse developments affecting that Underlying Fund and may be more susceptible to losses because of these developments.
Investments in ETFs [Member]
Prospectus [Line Items]
Risk [Text Block]	Investments in ETFs. The Fund may invest directly in ETFs, including affiliated ETFs. The Fund’s investments in ETFs will be subject to the restrictions applicable to investments by an investment company in other investment companies, unless relief is otherwise provided under the terms of a Securities and Exchange Commission (“SEC”) exemptive order or SEC exemptive rule.
Large Shareholder Transactions Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.
Leverage Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Leverage Risk.  Borrowing and the use of derivatives may result in leverage and may increase market exposure and make the Fund more volatile. The use of leverage may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet margin/collateral requirements when it may not be advantageous to do so. The use of leverage by the Fund can substantially increase the Fund’s investment risks and cause losses to be realized more quickly.
Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Liquidity Risk.  The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, declining prices of the securities sold, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell investments at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, potentially causing increased supply in the market due to selling activity. Redemptions by large shareholders may have a negative impact on the Fund’s liquidity.
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management Risk. A strategy used by the Investment Adviser may fail to produce the intended results.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. The value of the securities in which the Fund  invests may go up or down in response to the prospects of individual companies, particular sectors, governments or countries and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Events such as war, military conflict, geopolitical disputes, acts of terrorism, social or political unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions or the spread of infectious illness or other public health threats, or the threat or potential of one or more such events and developments, could also significantly impact the Fund and its investments.
NAV Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	NAV Risk.  The NAV of the Fund and the value of your investment may fluctuate.
Other Investment Companies Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Other Investment Companies Risk. By investing in other investment companies (including ETFs) indirectly through the Fund, investors will incur a proportionate share of the expenses of the other investment companies held by the Fund (including operating costs and investment management fees) in addition to the fees and expenses regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investment companies in direct proportion to the amount of assets the Fund invests therein.
Stock Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S.and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.
Swaps Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Swaps Risk.  In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged and subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.
Tax Diversification Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Tax Diversification Risk. The Fund intends to meet the diversification requirements that are applicable to insurance company separate accounts under Subchapter L of the Internal Revenue Code of 1986, as amended (the “Code”) (the “Diversification Requirements”). In order for the Fund to qualify for “look through” treatment under the Diversification Requirements, Fund shares must be sold only to persons permitted to hold shares, directly or indirectly (each, a “Permitted Investor”), under Section 817 of the Code and Treasury Regulation 1.817-5(f), as supplemented by published rulings and procedures issued thereunder by the Internal Revenue Service (“IRS”). To the extent an investor in Fund shares no longer qualifies as a Permitted Investor, and such investor fails to restore its status as a Permitted Investor or obtain a waiver or closing agreement with respect to such failure from the IRS, the Fund may no longer qualify for “look through” treatment. Therefore, in testing compliance with the Diversification Requirements, an investor in the Fund, such as, for example, an insurance company separate account, no longer would be able to look through the Fund to its underlying investments. Instead, the Fund would be considered a single investment for purposes of the Diversification Requirements. A failure to satisfy the Diversification Requirements (whether resulting from investors in Fund shares or otherwise) could have significant adverse tax consequences for variable contract owners whose contract values are determined by investment in the Fund. See “Taxation” in the Statement of Additional Information (the “SAI”) for more information.
US Government Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	U.S. Government Securities Risk. The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. government securities issued by those agencies, instrumentalities and government sponsored enterprises, including those issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal Home Loan Banks, are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. government securities held by  the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	Loss of money is a risk of investing in the Fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
