The DeepMM product suite

From market intelligence
to desk-level action.

Price with AXOR, our production pricing engine. Shape quotes with Hayek. Put an algorithmic trader to work with Mises. Three focused ways to bring event-driven intelligence to your desk.

AXOR

Our production pricing engine

Production pricing.
Exact trade context.

Live pricing intelligence for US corporate bonds, powered by our Large Event Model. Get a probability distribution conditioned on the trade you actually want to price.

  • Price the specific trade. Condition each inference on bond, size, side and ATS indicator.
  • See the full distribution. Work with price, spread or yield outcomes—not just a generic mark.
  • Connect to your desk. Integrate via API alongside your existing pricing signals and systems.
AXOR is our production pricing engine. Hayek is customer-data-powered RFQ intelligence. Mises is an algorithmic trader.

Mises

Algorithmic trading for the sell side

Make smaller trades
worth your desk’s time.

Put an algorithmic trader to work on smaller flow—and free your traders for bigger tickets, complex risk and client relationships.

  • Monetize smaller flow. Compete for eligible trades that do not justify manual attention.
  • Give the engine a mandate. Rebalance the book, exit positions or acquire inventory within desk-defined objectives.
  • Keep the desk in control. Set limits, permissions and execution boundaries, with supervision and human override.
Built on our leading Large Event Model (LEM) technology: market events and exact transaction context inform decisions—not one generic mark.

Why Mises? Named for Ludwig von Mises, whose criticism of communism and socialist central planning placed market prices at the heart of economic calculation.

HAYEK

Predictive intelligence for RFQ quoting

Your flow. Your edge.
A better-informed quote.

Turn proprietary RFQ and client-flow data into a predictive layer for price and quote formation, informed by market context.

  • Learn from what your desk sees. Bring RFQs, quotes, covers and outcomes together with relevant market signals.
  • Evaluate candidate quote levels. Use calibrated fill probabilities and price uncertainty where supported by your data and validation.
  • Retain your quote engine. Your desk owns the objective function, quote optimization, constraints and final decision.

The Paradigm Shift
What Every Firm Has Been Asking

"How do we use AI to cut costs?"

Large Language Models transformed industries built on words. They automate, summarise, and generate text — cost reduction, fewer people doing the same work.

For trading businesses, this is valuable. But it does not grow your trading revenue by a single dollar.

The Real Question

"How do we use AI to grow revenue?"

Financial markets are not built on words. They are built on events. Every trade, every quote, every rate move, every signal firing simultaneously across thousands of instruments.

No language model was ever designed to understand that world. Deep MM built one that is.

Deep MM did not build a better pricing tool. We built the first intelligence ever designed to understand a market.

Every firm is using the same signals — incumbent pricing models built on legacy technology with fewer than 1,000 parameters. These are the industry benchmarks. They define what the market treats as correct.

AXOR runs on 80 million parameters. Legacy models run on fewer than 1,000.

AXOR is the first signal ever independently validated as meaningfully more accurate than those benchmarks. By +44% on investment grade. By +48% on high yield. Evaluated on 400,000+ out-of-sample trades. Already live at a top-5 global bank.

A New Class of AI

A new class of AI
has been invented.

Deep MM's AXOR is the world's first Large Event Model — a new class of AI trained on market events, not language. Not adapted from a language model. Not a better quant model. Built from the ground up to understand what actually moves credit markets.

Large Language Model

Trained on words.

Transforms industries built on text — automates tasks, cuts costs, reduces headcount.

The Old Thinking

Does not grow your trading revenue by a single dollar.

Large Event Model — Deep MM AXOR

Trained on market events.

Processing thousands of signals simultaneously. Every trade, every quote, every rate move. Updating every 15–30 seconds. Seeing patterns no legacy model has the capacity to detect.

80 million parameters. 2,000+ intraday features per inference. The model knows the difference between a $100K offer and a $5M offer — because it was trained to.

Not a tool. Not a data feed. The signal that makes every other model in your stack more accurate.

The Key Difference

Not a price. A probability distribution.

While some signals include a confidence score, AXOR delivers the full probability distribution — the 5th through 95th percentile of possible outcomes, conditioned on your specific trade size, side, and market conditions. The market doesn't trade at a single price. Your signal shouldn't either.

Legacy Pricing Signal

Output: 127 bps — A single point estimate. No uncertainty. No size conditioning. The same number whether you're trading $100K or $5M.

AXOR — Large Event Model

Output: Full distribution — The 5th through 95th percentile of spread outcomes, conditioned on your specific trade: $1M notional, offer side, US IG corporate bond. The market doesn't trade at a single price. • Your signal shouldn't either.

This is why AXOR outperforms on large trades. The model is conditioned on trade size and side — a $5M offer produces a materially different distribution than a $100K bid. A confidence score tells you how certain a model is about its single estimate. AXOR's distribution tells you the full range of probable outcomes. Your risk is not the same on every trade — your signal should reflect that.

Proven Accuracy

The numbers are unambiguous.

Validated against the industry's published accuracy benchmarks. $0.049 median price error on IG. $0.082 on HY. Evaluated on 400,000+ out-of-sample trades, Jul–Sep 2025. The first model to demonstrably outperform those benchmarks at scale.1

44
+44%
Pricing Accuracy — Investment Grade

Lower median pricing error across a large sample — more consistently closer to the true market price than any competing signal, across all market conditions including stress.

48
+48%
Pricing Accuracy — High Yield

Superior precision on riskier, lower-rated bonds — exactly where pricing errors are most costly to a trading P&L, and exactly where legacy models degrade most severely.

01
Lower median error

More consistently closer to the true market price across all instruments and market regimes.

02
Resilient in volatility

All models degrade under stress. AXOR degrades significantly less — widening the accuracy gap exactly when stakes are highest.

03
Better on large trades

Where the P&L impact of a wrong signal is greatest — AXOR's size-conditional inference means it was built for this.

04
Precise on risky bonds

Superior accuracy on lower-rated, less liquid bonds — exactly where pricing errors are most costly to a trading P&L.

05
Faster response to macro moves

When rates shift or macro conditions change, AXOR maintains its accuracy advantage. Legacy models degrade most severely under macro stress — exactly when you need your signal most.

AXOR's price model was evaluated out-of-sample on 400,000+ trades from July through early September, 2025 — entirely after the model's model training cutoff, ensuring no data leakage. Only trades of notional size $150k or above were included.

Deep MM's median price error of $0.049 on IG and $0.082 on HY represents a 44% and 48% improvement respectively over the industry's published accuracy benchmarks. The gap holds consistently across trade sizes and throughout the trading day — including under volatile market conditions where legacy models degrade most.1

How It Works

Built differently.
By design.

AXOR is fed a live stream of real-time data the deep neural network has learned to extract signal from: FINRA TRACE (every US corporate bond trade), real-time treasury prices at all benchmark tenors, and equity market signals including SPY, QQQ, HYG, JNK and LQD — plus S&P credit ratings. Every inference is then conditioned on your specific trade parameters — bond identifier, quantity, side, and ATS indicator — producing a probability distribution unique to your trade.

01

FINRA TRACE Feed

Direct connection to FINRA's TRACE — every US corporate bond trade as it occurs, alongside real-time treasury prices at all benchmark tenors and live ETF market signals.

02

2,000+ Feature Extraction

AXOR extracts over 2,000 features per inference from TRACE prints, treasury benchmarks, SPY, QQQ, HYG, JNK, LQD and S&P ratings — simultaneously, in real time.

03

80M Parameter Inference

The LEM processes all signals through 80 million parameters — conditioned on your trade size, side, and ATS indicator — producing a complete probability distribution.

04

WebSocket Delivery

Subscribe to any bond in your universe. Receive the full distribution — 5th through 95th percentile — via WebSocket, refreshing every 15–30 seconds.

Platform-agnostic. No lock-in.

AXOR is delivered via WebSocket connection — one of the most universal data protocols in modern software. Your quant team can integrate the signal into any existing system or data pipeline without migrating off the tools your desk already uses.

No proprietary platform required. No new terminal. Connect once, subscribe to any bond in your universe, route the signal wherever you need it.

Deep MM did not build a better pricing tool.

We built the first intelligence ever designed to understand a market.

Our mission is to build AI analysts that help all credit professionals gain insight, confidence, and empowerment. AXOR is purpose-built for US IG and HY corporate bonds — the market where pricing accuracy has the highest P&L impact, and where legacy models fall furthest short.

We are expending more resources concentrated on US corporate bond pricing than JPMorgan was when Nathaniel built their model. This is all we do. And it shows in the numbers.

The Moment You Are In Right Now

This is the window.
Move first.

Think back to 2021. Before ChatGPT. Before every board was asking about AI strategy. There was a brief window when a small number of firms understood what was coming and moved first. This is that window for trading. The Large Event Model is live. A top-5 competitor is already using it. The rest of the industry will know within 12 to 18 months.
