Goldman Sachs International Equity Insights Fund Investment Risks - Institutional [Member] - Goldman Sachs International Equity Insights Fund	Dec. 31, 2025
European Investment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	European Investment Risk. The Fund is more exposed to the regulatory, economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse regulatory, economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (“EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries. While the EU-UK Trade and Cooperation Agreement governs certain aspects of the EU’s and UK’s relationship following the UK’s withdrawal from the EU (“Brexit”), the full effects of Brexit are unknown at this time and could negatively impact the value of the Fund’s investments.
Foreign and Emerging Countries Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign and Emerging Countries 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. These risks are more pronounced in connection with the Fund’s investments in securities of issuers located in, or otherwise economically tied to, emerging countries.
Investment Style Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Investment Style Risk. Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.
Japan Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Japan Risk. The Japanese economy is heavily dependent upon international trade and may be subject to considerable degrees of economic, political and social instability, which could negatively affect the Fund’s investments. Japan has limited natural resources and relies on imports to meet its commodity needs, such as fossil fuels. Fluctuations or shortages in the commodity markets, trade tariffs, and competition from emerging economies could have a negative impact on the Japanese economy. In the past, Japan’s economic growth has remained relatively low, and it may remain low in the future. The Japanese economic growth rate could be impacted by massive government debt, the Bank of Japan’s monetary policies, interest rate fluctuations, tax increases, budget deficits, consumer confidence and low domestic consumption, currency volatility, certain corporate structural weaknesses, an unstable financial sector, government policy, an aging demographic, a declining population and/or geopolitical conflicts, including with neighboring countries. The performance of the global economy could have a major impact upon equity returns in Japan. Japan has also experienced natural disasters, such as earthquakes and tsunamis, of varying degrees of severity, which could negatively affect the Fund’s investments.
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 net asset value (“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.
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. The Investment Adviser attempts to execute a complex strategy for the Fund using proprietary quantitative models. Investments selected using these models may perform differently than expected as a result of the factors used in the models, the weight placed on each factor, changes from the factors’ historical trends, and technical and other issues in the construction, implementation and maintenance of the models (including, for example, data problems, unauthorized changes and/or software issues). There is no guarantee that the Investment Adviser’s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.
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.
Mid Cap and Small Cap Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Mid-Cap and Small-Cap Risk. Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.
Portfolio Turnover Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Portfolio Turnover Rate Risk. A high rate of portfolio turnover involves correspondingly greater expenses which must be borne by the Fund and its shareholders.
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.
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.
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.
