first_img OpenAI grants free API credits to ChatGPT Pro and Business

OpenAI documentation shows that eligible ChatGPT Pro and Business subscriptions can receive free API credits for building applications and agents within their own API organization. The credits are automatically issued based on the subscription, and any unused portion expires at the end of the billing cycle without carrying over; when there are valid free credits, there is no need to bind an API payment method. In terms of monthly credits, Pro's tiers of $100, $200, and $500 correspond to $100, $200, and $500 respectively; Business Standard provides $20 per paid seat, and Business Premium provides $100 per paid seat.The initial issuance is calculated proportionally based on the remaining time in the current subscription billing cycle and expires at the end of that cycle. Business API credits are shared within the workspace, with a monthly cap of $500; annual payment workspaces receive a one-time issuance of the annual credits, which expire at the end of the annual billing cycle. Users must log in to ChatGPT with an eligible subscription account, with Pro credits claimed in Settings under Billing, and Business credits claimed in the workspace billing settings or Admin Console, confirming the API organization receiving the credits.The credits cover the paid usage of associated organizations on the API Platform, including Responses API, Agents API, Decisions API, GPT-Live and Realtime API, Images API, as well as built-in tools and related costs such as web search, document search, and Code Interpreter. Using Codex via API key is not included in the benefits, and the credits will not increase the usage limits for ChatGPT or Codex that is already logged in. Free credits are prioritized over purchased credits; when exhausted and no remaining credits are available, requests will fail with HTTP 429 and error code credit_balance_exhausted.

first_img Ethena Pay launched Earn+, aiming for rewards of up to 12%

Ethena Pay has begun rolling out the Earn+ feature, which claims that the dollar balance can earn a target annual reward of up to 12%. Initially, it is open to Pro and VIP users, with plans to expand to all users in the coming days. This feature will transfer funds from the main payment balance to an external Upshift vault, where Steakhouse Financial will execute a leveraged USDe strategy on Aave, aiming for a yield higher than the app's existing maximum tiered reward of 6%.According to documents released by Ethena Pay, the vault targets approximately 11 times leverage on Aave v4 on Avalanche, packaging repeated borrowing and reinvestment into a one-click deposit. The specific path involves depositing USDe as collateral, borrowing USDT, and then using the borrowed tokens to purchase more USDe in a loop, with returns depending on whether the USDe rewards can cover the USDT borrowing costs. Ethena Pay states that it only provides the interface and does not guarantee the assets, and users must bear the risk of vault losses, which may result in losing part or all of their invested funds.Ethena Pay claims that the simplified interface does not eliminate liquidation risk; when collateral is insufficient to cover debts, positions will face liquidation, with liquidators repaying debts and taking collateral and rewards. The 12% is only a target and not a guaranteed return, rates may be adjusted downwards, and Earn+ balances do not enjoy the Daily Boost of the main account. This product has no lock-up period, no fees for deposits or withdrawals, and withdrawals are processed to the main dollar account within 24 hours but may be delayed, and are not considered insured bank deposits. The initial total capacity limit for the vault is $4.5 million, with individual limits of $50,000 and $200,000 for Pro and VIP users, respectively, and $20,000 for Standard users.

OpenAI announced the model breakthrough index time hypothesis

OpenAI recently announced that its AI model has cracked the Exponential Time Hypothesis, abbreviated as ETH, which has been a longstanding conjecture in computer science for over twenty years, and is not related to Ethereum. This hypothesis focuses on how difficult particularly hard problems are, using the Boolean Satisfiability Problem (SAT) as an example: given a set of logical conditions, is there an assignment that makes all conditions true simultaneously? As the problem size increases, the best-known methods essentially can only try possible answers one by one, with the time cost growing exponentially with the size. The Exponential Time Hypothesis further asserts that such problems cannot be significantly accelerated, and there are no truly sub-exponential time efficient algorithms.Since its proposal in 1999, this hypothesis has been a crucial cornerstone of theoretical computer science, with numerous papers proving that certain problems are hard and that some algorithms are close to optimal based on it. If the Exponential Time Hypothesis were to be overturned, it would imply that many problems considered nearly impossible to solve faster might theoretically have better solutions. OpenAI claims that its model has found a deterministic algorithm that can accurately count the number of solutions to the k-SAT problem in sub-exponential time, and it has been formally verified using Lean. If this result withstands expert scrutiny, it will directly challenge the Exponential Time Hypothesis.

Bitget partners with VETA Finance to upgrade stock dual-currency investment and expand the tokenized wealth management scenarios for U.S. stocks

According to official news from Bitget, the platform announced a collaboration with the structured product liquidity service provider VETA Finance to upgrade its stock dual-currency investment products. This upgrade expands the product pool on top of existing popular targets such as NVIDIA (rNVDA), Google (rGOOGL), and AMD (rAMD), enriching the investment duration options; relying on deeper liquidity support, it offers more competitive annualized returns while optimizing product structure and settlement mechanisms, bringing users a better trading experience and more diverse income opportunities.Currently, Bitget's stock dual-currency investment supports two strategies: "buy low" and "sell high." Users can use USDT or eligible U.S. stock tokens for subscription, and based on preset target prices and investment durations, complete corresponding asset conversions according to the settlement price at maturity and receive corresponding interest income.In addition, Bitget also plans to launch structured products such as accumulation purchase and accumulation sale options (AQ) with VETA Finance based on the rToken ecosystem, expanding the product layout from standardized wealth management to customized solutions, further enriching multi-asset wealth management options under the panoramic exchange (UEX) ecosystem.
