Organization and Business [Abstract]
Organization and Business	1. Organization and Business
	The Blended Strategies Portfolio (the “Fund”) is a series of Graham Alternative Investment Fund I LLC (“GAIF I”), a Delaware Series Limited Liability Company established through an amendment to the certificate of formation, effective March 28, 2013. GAIF I has two other series in addition to the Fund, Systematic Strategies Portfolio and Discretionary Strategies Portfolio. GAIF I commenced the liquidation process for the Discretionary Strategies Portfolio on July 31, 2014. Prior to March 28, 2013, GAIF I was organized as a Delaware Limited Liability Company which was formed on May 16, 2006 and commenced operations on August 1, 2006. Comparative information contained within these financial statements for periods prior to March 28, 2013 represent the data pertaining solely to the Blended Strategies Portfolio. GAIF I is registered as a commodity pool with the U.S. Commodity Futures Trading Commission.
	As a Series Limited Liability Company each series is legally segregated, and the assets associated with each series are held separately and accounted for in separate and distinct records from the assets of any other series of GAIF I. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular series are enforceable against the assets of such series only, and not against the assets of GAIF I generally or any other series thereof. Further, none of the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to GAIF I are enforceable against the assets of any other series.
	The Fund offers investors Class 0 and Class 2 units. The Fund invests all of its assets dedicated to trading in Graham Alternative Investment Trading LLC (“GAIT”), a Delaware Limited Liability Company which was formed on May 18, 2006 and commenced operations on August 1, 2006. GAIT invests in various master trading vehicles (“Master Funds”), all of which are managed by Graham Capital Management, L.P. (the “Advisor” or “Manager”). The Manager is the manager and the sole investment advisor of GAIT and the Fund. The Manager is registered as a Commodity Pool Operator and Commodity Trading Advisor with the U.S. Commodity Futures Trading Commission and is a member of the National Futures Association. The Manager is also registered as a Registered Investment Advisor with the Securities and Exchange Commission. The Fund’s Units are registered under the Securities Exchange Act of 1934.
	The investment objective of the Fund is to achieve long-term capital appreciation through professionally managed trading in both U.S. and foreign markets primarily in futures contracts, forwards contracts, spot currency contracts, and associated derivative instruments, such as options and swaps, through its investment in GAIT, which in turn invests in various Master Funds. The Master Funds seek to profit from opportunities in the global financial markets, including interest rate futures, foreign exchange, global stock indices and energy, metals and agricultural futures, as professionally managed multi-strategy investment vehicles. Each of the investment programs consists of multiple trading strategies of the Manager, which the Manager has combined in an effort to diversify the Fund’s investment exposure and to make the Fund’s performance returns less volatile and more consistently profitable.
	SEI Global Services, Inc. (“SEI”) is the Fund’s independent administrator and transfer agent. SEI is responsible for certain matters pertaining to the administration of the Fund.
	The Fund will terminate on December 31, 2050 or at an earlier date if certain conditions occur as outlined in the Limited Liability Company Agreement (“LLC Agreement”).
	The performance of the Fund is directly affected by the performance of GAIT; therefore these financial statements should be read in conjunction with the attached financial statements of GAIT.
	Duties of the Manager
	Subject to the terms and conditions of the LLC Agreement, the Manager has complete and exclusive responsibility for managing and administering the affairs of the Fund and for directing the investment and reinvestment of the assets of the Fund and GAIT.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies
	These financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) and all amounts are stated in U.S. dollars. The Fund is an investment company and applies specialized accounting guidance as outlined in Financial Accounting Standards Board Accounting Standards Update 2013-08, Financial Services – Investment Companies (Topic 946), Amendments to the Scope, Measurement, and Disclosure Requirements. The Manager has evaluated this guidance and has determined the Fund meets the criteria to be classified as an investment company. The preparation of these financial statements requires the Manager to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
	Investment in Graham Alternative Investment Trading LLC
	The Fund records its investment in GAIT at fair value based upon the Fund’s proportionate share of GAIT’s reported net asset value in accordance with U.S. GAAP. In determining its net asset value, GAIT records its investments in Master Funds at fair value based upon GAIT’s proportionate share of the Master Funds’ reported net asset value. The Fund records its proportionate share of GAIT’s investment income and loss, expenses, fees, and realized and unrealized gains and losses on a monthly basis and includes them in the statements of operations. Purchases and sales of units in GAIT are recorded on a trade date basis. The accounting policies of GAIT are described in its attached financial statements.
	GAIT charges its investors, including the Fund, an advisory fee, sponsor fee, and incentive allocation, all of which are described in detail in Note 4. The Fund does not charge any additional fees; however each investor in the Fund indirectly bears a portion of the advisory fee, sponsor fee, and incentive allocation charged by GAIT.
	At December 31, 2014 and 2013, the Fund owned 52.82% and 54.85%, respectively of GAIT.
	Fair Value
	The fair value of the assets and liabilities of the Fund and GAIT, which qualify as financial instruments under U.S. GAAP, approximates the carrying amounts presented in the statements of financial condition. Changes in these carrying amounts are included in the statements of operations.
	The Fund follows U.S. GAAP for fair value measurements, which defines fair value, establishes a framework for measuring fair value, and requires certain disclosures about fair value measurements. The Fund reports the fair value of its investment related assets and liabilities in accordance with the hierarchy established under U.S. GAAP. U.S. GAAP uses a three level hierarchy for fair value measurement based on the activeness of the market and the transparency and independence of inputs used in the valuation of an asset or liability as of the measurement date.
	The fair value hierarchy categorizes asset and liability positions into one of three levels, as summarized below, based on the inputs and assumptions used in deriving fair value.
		·	Level 1 inputs are unadjusted closing or settlement prices for such assets or liabilities as published by the primary exchange upon which they are traded.
		·	Level 2 inputs include quoted prices for similar assets and liabilities obtained from independent brokers and/or market makers in each security. With respect to the Fund’s investment in GAIT, Level 2 inputs include the net asset value of the underlying fund in which it holds an investment.
		·	Level 3 inputs are those which are considered unobservable and are significant in arriving at fair value.
	In accordance with this hierarchy, the Fund’s investment in GAIT has been classified as a Level 2 valuation. There were no Level 3 assets or liabilities held at any point during the years ended December 31, 2014 and 2013 by the Fund, GAIT, or the Master Funds, and there were no transfers between levels during those periods. Transfers between levels, if any, are recognized on the actual date of the event or change in circumstances that cause the transfer.
	Recent Accounting Pronouncement
	In August 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-15 – Presentation of Financial Statements – Going Concern (Subtopic 205-40). The pronouncement determines management’s responsibility regarding the assessment of the Fund’s ability to continue as a going concern even if the Fund’s liquidation is not imminent. Under this guidance, during each period in which financial statements are prepared, management will need to evaluate whether there are conditions or events that, in the aggregate, raise substantial doubt about the Fund’s ability to continue as a going concern within one year after the date the financial statements are issued. Substantial doubt would exist if conditions or events indicate that the Fund will be unable to meet its obligations as they become due. Accounting Standards Update 2014-15 is effective for annual periods ending after December 15, 2016, however early adoption is permitted. The Manager is currently assessing the impact that this pronouncement will have on the financial statements.
	Indemnifications
	In the normal course of business, the Master Funds, GAIT, Graham Cash Assets LLC (“Cash Assets”), and the Fund enter into contracts that contain a variety of indemnifications. Such contracts may include those by Cash Assets and the Master Funds with their brokers and trading counterparties. The Fund’s maximum exposure under these arrangements is unknown; however, the Fund has not had prior claims or losses with respect to such indemnifications and considers the risk of loss to be remote.

Capital Accounts [Abstract]
Capital Accounts	3. Capital Accounts
	The Fund offers two classes (each a “Class”) of Units (collectively the “Units”), being Class 0 Units and Class 2 Units. The Fund may issue additional Classes in the future subject to different fees, expenses or other terms, or to invest in other investment programs or combinations of investment programs managed by the Manager.
	A separate Capital Account is maintained for each Member with respect to each member’s Class of Units. The initial balance of each Member’s Capital Account is equal to the initial contribution to the Fund by such Member with respect to the Class to which such Capital Account relates. Each Member’s Capital Account is increased by any additional subscription, and decreased by any redemption by such Member of Units of such Class to which the Capital Account relates. All income and expenses of the Fund are allocated among the Members’ Capital Accounts in proportion to the balance that each Capital Account bears to the balance of all Capital as of the beginning of such fiscal period.
	Subscriptions
	Units may be purchased at a price equal to the Net Asset Value per Unit of the relevant Class as of the immediately preceding Valuation Day as defined in the LLC Agreement. The minimum initial subscription from each investor in each Class is $50,000. Members may subscribe for additional Units in a minimum amount of not less than $5,000.
	Units are available for subscription as of the first business day of each month upon written notice of at least three business days prior to the last business day of the preceding month.
	Redemption of Units
	Units are not subject to any minimum holding period. Members may redeem Units at the Net Asset Value thereof as of each Valuation Day, as defined in the LLC Agreement, upon not less than three business days’ prior written notice to the administrator. A partial redemption request for an amount less than $10,000 will not be accepted, nor will a redemption request be accepted to the extent that it would result in an investor owning less than $25,000. The redemption proceeds will normally be remitted within 15 days after the Valuation Day, without interest for the period from the Valuation Day to the payment date.
	Redemption Fees
	Class 2 Units are subject to a redemption fee equal to 2% of their Net Asset Value if redeemed within six months from their subscription date and a redemption fee equal to 1% of their Net Asset Value if redeemed more than six and less than twelve months from their subscription date. Class 0 Units are not subject to a redemption fee. Redemption fees are payable to the Manager upon redemption of Units from the proceeds of such redemption. Redemption fees of $0 and $4,244 were paid to the Manager for the years ended December 31, 2014 and 2013, respectively, and are included as redemptions in the statements of changes in members’ capital.

Fees and Related Party Transactions	4. Fees and Related Party Transactions
	Advisory Fees
	For the years ended December 31, 2014 and 2013, each Class of GAIT other than Class M paid the Manager an advisory fee (the “Advisory Fee”) at an aggregate annual rate equal to 1.75% of the Net Asset Value of such Class. The Advisory Fee is payable monthly in arrears calculated as of the last business day of each month and any other date the Manager may permit, in its sole and absolute discretion, as of which any subscription or redemption is effected with respect to Units of such Class during the month.
	Sponsor Fees
	For the years ended December 31, 2014 and 2013, each Class of GAIT other than Class M paid the Manager a sponsor fee (the “Sponsor Fee”) at an annual rate of the Net Asset Value specified in the table below. The Sponsor Fee is payable monthly in arrears calculated as of the last business day of each month in the same manner as the Advisory Fee. For the three months ended March 31, 2013, the annual rate listed below for Class 2 comprised a Sponsor Fee of 0.75% and selling agent fee (the “Selling Agent Fee”) of 2%, which was used to compensate selling agents for initial and on-going services to the Fund. Subsequent to March 31, 2013, the Sponsor Fee and the Selling Agent Fee were combined to form the Sponsor Fee listed in the table below.
	Class	Annual Rate
	Class 0		0.75	%
	Class 2		2.75	%
	Incentive Allocation
	At the end of each calendar quarter, the Manager of GAIT will receive a special allocation of net profits (the “Incentive Allocation”) in an amount equal to 20% of the New High Net Trading Profits of each Class of GAIT, as defined in the LLC Agreement. The Incentive Allocation is also accrued and allocable on the date of redemption with respect to any Units that are redeemed prior to the end of a calendar quarter. Additionally, any loss carryforward attributable to any class of GAIT shall be proportionately reduced, effective as of the date of any redemption of any Units of such class, by multiplying the loss carryforward by the ratio that the amount of assets redeemed from such class bears to the net assets of such class immediately prior to such redemption. The loss carryforward of a class must be recouped before any subsequent Incentive Allocation can be made to the Manager. The total Incentive Allocation allocated to the Fund by GAIT for the years ended December 31, 2014 and 2013 were $1,924,711 and $0, respectively.
	Administrator’s Fee
	For the years ended December 31, 2014 and 2013, GAIT paid SEI a monthly administrator’s fee based on GAIT’s net asset value, calculated as of the last business day of each month. In addition, GAIT reimbursed SEI for reasonable out-of-pocket expenses incurred on behalf of GAIT. The total administrator’s fees, including out-of-pocket expenses, allocated to the Fund by GAIT for the years ended December 31, 2014 and 2013 were $121,838 and $168,689, respectively.
	Any portion of any of the above fees, including the Incentive Allocation, may be paid by the Manager to third parties as compensation for selling activities in connection with the Fund.

Income Taxes [Abstract]
Income Taxes	5. Income Taxes
	No provision for income taxes has been made in the accompanying financial statements, as members are individually responsible for reporting income or loss based upon their respective share of the Fund’s revenues and expenses for income tax purposes.
	U.S. GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. U.S. GAAP requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet a more-likely-than-not threshold would be recorded as a tax expense in the current year and the Fund identifies its major tax jurisdictions as U.S. Federal and Connecticut State. The Manager has evaluated the Fund’s tax positions and has concluded that there are no significant tax positions requiring recognition, measurement or disclosure in the financial statements for open tax years 2010 through 2013 or expected to be taken in the Fund’s 2014 tax returns. The Manager has evaluated the Fund’s tax positions and has concluded that there are no significant tax positions requiring recognition, measurement or disclosure in the financial statements. The Manager is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax expense will change materially in the next twelve months. Tax years which are considered open by the relevant jurisdiction are subject to potential examination.

	Total expenses after Incentive Allocation		5.21	%		3.02	%		6.98	%		4.96	%
	Total return is calculated for Class 0 and Class 2 Units taken as a whole. Total return is calculated as the change in total members’ capital adjusted for subscriptions or redemptions during the period. An individual member’s return may vary from these returns based on the timing of capital transactions and the applicability of Advisory Fees, Sponsor Fees, and the Incentive Allocation. The net investment loss and total expense ratios (including Incentive Allocation) are calculated for Class 0 and Class 2 Units taken as a whole and include net amounts allocated from GAIT. The computation of such ratios is based on the amount of net investment loss, expenses and Incentive Allocation. Net investment loss and total expense ratios are computed based upon the weighted average of members’ capital for Class 0 and Class 2 Units of the Fund for the years ended December 31, 2014 and 2013.

	The Fund follows U.S. GAAP for fair value measurements, which defines fair value, establishes a framework for measuring fair value, and requires certain disclosures about fair value measurements. The Fund reports the fair value of its investment related assets and liabilities in accordance with the hierarchy established under U.S. GAAP. U.S. GAAP uses a three level hierarchy for fair value measurement based on the activeness of the market and the transparency and independence of inputs used in the valuation of an asset or liability as of the measurement date.
	The fair value hierarchy categorizes asset and liability positions into one of three levels, as summarized below, based on the inputs and assumptions used in deriving fair value.
		·	Level 1 inputs are unadjusted closing or settlement prices for such assets or liabilities as published by the primary exchange upon which they are traded.
		·	Level 2 inputs include quoted prices for similar assets and liabilities obtained from independent brokers and/or market makers in each security. With respect to the Fund’s investment in GAIT, Level 2 inputs include the net asset value of the underlying fund in which it holds an investment.
		·	Level 3 inputs are those which are considered unobservable and are significant in arriving at fair value.
	In accordance with this hierarchy, the Fund’s investment in GAIT has been classified as a Level 2 valuation. There were no Level 3 assets or liabilities held at any point during the years ended December 31, 2014 and 2013 by the Fund, GAIT, or the Master Funds, and there were no transfers between levels during those periods. Transfers between levels, if any, are recognized on the actual date of the event or change in circumstances that cause the transfer.
Recent Accounting Pronouncements	Recent Accounting Pronouncement
	In August 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-15 – Presentation of Financial Statements – Going Concern (Subtopic 205-40). The pronouncement determines management’s responsibility regarding the assessment of the Fund’s ability to continue as a going concern even if the Fund’s liquidation is not imminent. Under this guidance, during each period in which financial statements are prepared, management will need to evaluate whether there are conditions or events that, in the aggregate, raise substantial doubt about the Fund’s ability to continue as a going concern within one year after the date the financial statements are issued. Substantial doubt would exist if conditions or events indicate that the Fund will be unable to meet its obligations as they become due. Accounting Standards Update 2014-15 is effective for annual periods ending after December 15, 2016, however early adoption is permitted. The Manager is currently assessing the impact that this pronouncement will have on the financial statements.
Indemnifications	Indemnifications
	In the normal course of business, the Master Funds, GAIT, Graham Cash Assets LLC (“Cash Assets”), and the Fund enter into contracts that contain a variety of indemnifications. Such contracts may include those by Cash Assets and the Master Funds with their brokers and trading counterparties. The Fund’s maximum exposure under these arrangements is unknown; however, the Fund has not had prior claims or losses with respect to such indemnifications and considers the risk of loss to be remote.
