Model Architecture

Buddhi-128K-Chat-7B is fine-tuned from the Mistral-7B Instruct v0.2 base model, selected for its superior reasoning capabilities. The Mistral-7B architecture incorporates features such as Grouped-Query Attention and a Byte-fallback BPE tokenizer, originally supporting a maximum of 32,768 position embeddings. To extend this to 128K, the Yet another Rope Extension (YaRN) technique was employed, modifying positional embeddings to accommodate the increased context length.

The London Whale trading scandal was one of the largest trading losses in financial history, involving JPMorgan Chase & Co. It was caused by high-risk trading activities within the bank’s Chief Investment Office (CIO), resulting in $6.2 billion in losses. The scandal led to regulatory fines, reputational damage, and increased scrutiny of JPMorgan’s risk management practices.

The Trading Strategy

The CIO was originally responsible for investing excess deposits in relatively safe assets. However, it began engaging in riskier trades using synthetic credit derivatives, specifically credit default swaps (CDS), which are financial instruments used to hedge credit risk.

How the Trades Went Wrong

1. Massive CDS Positions: The CIO built an enormous position in a specific CDS index (CDX.NA.IG.9), betting that credit markets would remain stable.
2. Market Distortion: The sheer size of these trades (up to $157 billion in notional value) distorted the market, drawing attention from hedge funds and traders.
3. Mounting Losses: As market conditions changed, the position moved against JPMorgan, leading to billions in paper losses.
4. Attempts to Hide Losses: Internal emails and messages suggest that traders attempted to delay recognizing losses, allegedly misrepresenting valuations to minimize reported losses.
