Expense Narrative [Text Block] oef_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Portfolio. The table and the example do not include any fees or sales charges imposed by your variable annuity or variable life insurance contract. If they were included, your costs would be higher. Please refer to your variable contract prospectus for information on the separate account fees and expenses associated with your contract.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text] oef_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees Acquired Fund Fees and Expenses are the indirect cost of investing in other investment companies, the costs of which will not be included in the Portfolio's financial statements. The operating expenses in this fee table will not correlate to the expense ratio in the Portfolio's financial highlights because the financial statements include only the direct operating expenses incurred by the Portfolio.
Expense Example [Heading] oef_ExpenseExampleHeading Example:
Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. You would pay the same expenses if you did not redeem your shares. However, each variable contract and separate account involves fees and expenses that are not included in the Example. If these fees and expenses were included in the Example, your overall expenses would be higher. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same (except that the Example reflects any applicable contractual fee waivers/expense reimbursement arrangements for only the first year). Although your actual costs may be higher or lower, based upon these assumptions your costs would be:
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover:
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities or instruments (or "turns over" its portfolio). These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio's performance. A higher portfolio turnover rate may indicate higher transaction costs. During the most recent fiscal year ended December 31, 2025, the Portfolio's portfolio turnover rate was 56% of the average value of its portfolio.
Portfolio Turnover, Rate oef_PortfolioTurnoverRate 56.00%
Strategy [Heading] oef_StrategyHeading Principal Investment Strategies:
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities. Securities selected will consist of developed market equity securities and emerging market equities, of companies with similar capitalizations of the companies included in the MSCI ACWI ex-USA Index, selected using a proprietary quantitative model. The model systematically tracks and ranks the characteristics of issuers across developed and emerging markets, and is designed to select stocks based on an analysis of a wide range of factors, such as relative value; earnings quality; market sentiment; and thematic insights. The Portfolio's sub-adviser is BlackRock Investment Management, LLC ("BlackRock" or the "Sub-Adviser").

Equity securities include common stock, preferred stock, exchange-traded funds ("ETFs"), including ETFs that are affiliated with the Sub-Adviser, securities convertible into common stock and securities or other instruments whose price is linked to the value of common stock. Preferred stock is a class of stock that often pays dividends at a specified rate and has preference over common stock in dividend payments and liquidation of assets. Convertible securities typically pay current income as either interest (debt security convertibles) or dividends (preferred stock), and their value usually reflects both the stream of current income payments and the market value of the underlying common stock.

Under normal circumstances, at least 80% of the Portfolio's net assets will be invested in or exposed to securities of non-U.S. issuers ("foreign securities") or derivative instruments with exposure to foreign securities of at least three different countries outside the United States. Investments are deemed to be "foreign" if: (a) an issuer's domicile or location of headquarters is in a foreign country; (b) an issuer derives a significant proportion (at least 50%) of its revenues or profits from goods produced or sold, investments made, or services performed in a foreign country or has at least 50% of its assets situated in a foreign country; (c) the principal trading market for a security is located in a foreign country; (d) it is a foreign currency or (e) is an exchange-traded fund predominately invested in companies listed in a foreign country. The Portfolio may invest in securities of foreign issuers in the form of depositary receipts or other securities that are convertible into securities of foreign issuers.

The Portfolio may use derivatives, including futures, foreign exchange transactions, and/or forward foreign currency contracts to gain equity exposure and to manage cash flows into or out of the Portfolio effectively. Derivatives are financial instruments whose value is derived from underlying market factors or another asset, such as a security, a commodity, a currency or an index.

Bar Chart and Performance Table [Heading] oef_BarChartAndPerformanceTableHeading Performance:
Performance Narrative [Text Block] oef_PerformanceNarrativeTextBlock

The bar chart and performance table below show the variability of the Portfolio's returns, which is some indication of the risks of investing in the Portfolio. The bar chart shows performance of the Portfolio's Class I shares for each full calendar year since the Portfolio's inception and the table shows how the average annual total returns of the Portfolio's Class I shares compared with the returns of an index that measures broad market performance. The performance in the bar chart and the table does not include the effect of variable contract charges. If variable contract charges had been included, performance would have been lower. Because all of the Portfolio's shares are invested in the same portfolio of securities, returns for the Portfolio's Class II shares differ only to the extent that the classes do not have the same expenses. You should be aware that the Portfolio's past performance may not be an indication of how the Portfolio will perform in the future.

Global Atlantic BlackRock Disciplined International Core Portfolio | Affiliated Underlying Fund Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Affiliated Underlying Fund Risk: The Portfolio invests in Underlying Funds that are affiliated with a Sub-Adviser. The Sub-Adviser is subject to conflicts of interest when allocating Portfolio assets among the various Underlying Funds both because the fees payable to it and/or its affiliates by some Underlying Funds are higher than the fees payable by other Underlying Funds and because the Sub-Adviser and its affiliates are also responsible for managing the Underlying Funds.
Global Atlantic BlackRock Disciplined International Core Portfolio | Convertible Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Convertible Securities Risk: The market value of a convertible security is usually inversely related to the market interest rate. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer's credit rating or the market's perception of the issuer's creditworthiness. A convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock into which it may be converted.
Global Atlantic BlackRock Disciplined International Core Portfolio | Depositary Receipts Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Depositary Receipts Risk: American Depositary Receipts are receipts typically issued by an American bank or trust company that evidence underlying securities issued by a foreign corporation. The Portfolio may invest in unsponsored Depositary Receipts. Depositary Receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted, including changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies.
Global Atlantic BlackRock Disciplined International Core Portfolio | Derivatives Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Derivatives Risk: The use of derivatives may increase costs, reduce the Portfolio's returns and/or increase volatility. The use of derivatives may also result in leverage, which can magnify the effects of changes in the value of investments, make such investments more volatile and expose the Portfolio to losses that exceed the initial amount invested. Many types of derivatives are also subject to the risk that the other party in the transaction will not fulfill its contractual obligation. Derivatives are subject to risks arising from margin requirements. In addition, the fluctuations in the values of derivatives may not correlate perfectly with, and may be more sensitive to market events than, the overall securities markets. The possible lack of a liquid secondary market for derivatives and the resulting inability to sell or otherwise close-out a derivatives position at an advantageous time or price could expose the Portfolio to losses and could make derivatives more difficult to value accurately. Derivative investments are further subject to regulatory risks, from both U.S. and foreign regulators that may impact the availability, liquidity and costs associated with such investments and potentially limit the ability of mutual funds to invest in derivatives.
Global Atlantic BlackRock Disciplined International Core Portfolio | Emerging Markets Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Emerging Markets Risk: Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.

Risk [Text Block] oef_RiskTextBlock

Equity Risk: Common and preferred stock prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.
Global Atlantic BlackRock Disciplined International Core Portfolio | ETF Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

ETF Risk: Investments in underlying ETFs typically present the same risks as investments in conventional Underlying Funds. In addition, disruptions to the creations and redemptions process through which market makers directly purchase and sell ETF shares, the existence of extreme market volatility or potential lack of an active trading market, or changes in the liquidity of the market for an ETF's underlying portfolio holdings, may result in the ETF's shares trading at significantly above (at a premium to) or below (at a discount to) net asset value, which may result in a Portfolio paying significantly more or receiving significantly less for ETF shares than the value of the relevant ETF's underlying holdings. Because the value of ETF shares depends on the demand in the market, the Portfolio may not be able to liquidate its holdings at the most optimal time, adversely affecting performance.
Global Atlantic BlackRock Disciplined International Core Portfolio | Foreign Currency Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Foreign Currency Risk: Exposure to foreign securities denominated in non-US dollar currencies will subject the Portfolio to currency trading risks that include market risk and country risk. Market risk results from adverse changes in exchange rates. Country risk arises because a government may interfere with transactions in its currency.
Global Atlantic BlackRock Disciplined International Core Portfolio | Foreign Investment Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Foreign Investment Risk: Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity,

greater volatility, restrictions on capital movements, less developed or less efficient trading markets, political instability, sanctions, and differing auditing and legal standards.
Global Atlantic BlackRock Disciplined International Core Portfolio | Forward Currency Contracts Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Forward Currency Contracts Risk: Use of forward currency contracts can have the effect of reducing returns, limiting opportunities for gain and creating losses. Forward currency contracts do not eliminate fluctuations in the value of foreign securities but allow the Portfolio to establish a fixed rate of exchange for a future point in time.
Global Atlantic BlackRock Disciplined International Core Portfolio | Issuer Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Issuer Risk: The value of a security may decline for a number of reasons that directly relate to the issuer, such as management performance or the historical and prospective earnings of the issuer.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Market Risk: Overall securities market risks may affect the value of individual securities. The market prices of securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions. Factors such as foreign and domestic economic growth and market conditions, interest rate levels, and political events may adversely affect the securities markets. Local, regional or global events such as war, military conflict, geopolitical disputes, acts of terrorism, the spread of infectious illness or other public health issues, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions, increased government spending, social or political unrest or other events, or the threat or potential threat of one or more such events and developments, could also have a significant impact on the Portfolio and its investments.
Global Atlantic BlackRock Disciplined International Core Portfolio | Over-the-Counter Transactions Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Over-the-Counter Transactions Risk: The Portfolio engages in over-the-counter ("OTC") transactions, some of 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 transactions entered into on organized exchanges, with OTC transactions subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations.
Global Atlantic BlackRock Disciplined International Core Portfolio | Quantitative Investing Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Quantitative Investing Risk: Investments selected using quantitative analysis or "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 issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the use of these models will result in effective investment decisions for the Portfolio.
Global Atlantic BlackRock Disciplined International Core Portfolio | Settlement Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Settlement Risk: Settlement risk is the risk that a settlement in a transfer system does not take place as expected. If the Portfolio cannot settle or is delayed in settling a sale of securities, it may lose money if the value of the security then declines or, if it has contracted to sell the security to another party, the Portfolio could be liable for any losses incurred.
Global Atlantic BlackRock Disciplined International Core Portfolio | Underlying Fund Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Underlying Fund Risk: Underlying Funds are subject to investment advisory and other expenses, which will be indirectly paid by the Portfolio. As a result, your cost of investing in the Portfolio will be higher than the cost of investing directly in an Underlying Fund and may be higher than other mutual funds that invest directly in stocks and bonds. Because the Portfolio's investments include shares of the Underlying Funds, the Portfolio's risks include the risks of each Underlying Fund.

[1] The "Other Expenses" for Class III shares are based on estimated amounts.
[2] Acquired Fund Fees and Expenses are the indirect cost of investing in other investment companies, the costs of which will not be included in the Portfolio's financial statements. The operating expenses in this fee table will not correlate to the expense ratio in the Portfolio's financial highlights because the financial statements include only the direct operating expenses incurred by the Portfolio.
[3] The Portfolio's investment adviser, Global Atlantic Investment Advisors, LLC (the "Adviser"), has contractually agreed to waive its fees and to reimburse expenses, at least until May 1, 2027, to ensure that total annual portfolio operating expenses after fee waiver and/or reimbursement (exclusive of any front-end or contingent deferred loads, brokerage fees and commissions, Acquired Fund Fees and Expenses, borrowing costs (such as interest and dividend expense on securities sold short), taxes and extraordinary expenses, such as litigation) will not exceed 0.79%, 1.04%, and 0.94% of average daily net assets attributable to Class I, Class II and Class III shares of the Portfolio, respectively. The expense reimbursement is subject to possible recoupment from the Portfolio in future years on a rolling three-year basis (within the three years after the fees have been waived or reimbursed) if such recoupment, after giving effect to the recoupment amount, can be achieved within the lesser of the expense limits listed above and any expense limits applicable at the time of recoupment. The agreements may be terminated only by the Portfolio's Board of Trustees, on 60 days' written notice to the Adviser.
