The first vehicle from Karma Eximius debuts today at the 2026 Concours at Wynn Las Vegas. A menacing four-seater purpose-built for the track, “Eximius 1” is in ongoing development with its commissioning client, who is not revealed at this time. Upon delivery in 2027, “Eximius 1” will be fitted with an extreme-performance Plug-in Series Hybrid utilizing a 6.2 Liter V8 producing nearly 1200hp (550hp ICE, 645hp battery), delivering acceleration from 0-60mph in 2.7 seconds and a top speed in excess of 200mph (estimated). As these parameters would demand, “Eximius 1” will be equipped with carbon-ceramic brakes and two-piece slotted brake rotors, and Ohlins semi-active suspension.

“‘Eximius 1’ began as a conversation with an elite client who loves their Karma Revero, but wanted something more extreme and unexpected, which was music to our ears,” says Marques McCammon, President and Chief Executive, Karma Automotive. “The Eximius program effectively deletes the word ‘no’ from conversations about what’s possible,” he continues, “and as a four-seat track weapon packing what’ll be the most powerful Plug-in Series Hybrid powertrain and vehicle ever developed, ‘Eximius 1’ shatters expectations and further establishes Karma as a manufacturer of exotic, uniquely American vehicles.” 

Exterior Design
“Eximius 1” is an imposing vehicle to behold, exhibiting the muscularity and eyepopping strength of a superhero. Every panel – excluding the body surface outer – is constructed of pre-impregnated carbon fiber, and the vehicle is 50mm wider due to its wheel arch extensions. The front doors and hood have a unique technical fade from glossy, exposed regular carbon fiber to signature Borealis Blue paint.

The front carbon splitter sets an aggressive tone and is flanked by massive side air intakes incorporating Karma’s Target Acquisition Lighting, rotated 45º to create a distinctive ‘><‘ DRL graphic identity. On the hood, the dramatic arc of the Comet Line – which is inspired by Halley’s Comet is it streaks across the evening sky – widens from its apex towards the base of the windshield; vents above the front fenders release air pressure from the wheel housings and add further visual intrigue. Moving to the side of the vehicle, the front fenders aft of the wheels feature Karma’s signature “Backslash” bearing the number “5,” which is of particular significance to the commissioning client. 21″ Magnesium wheels with center-locks reduce rotating and unsprung mass, and are finished in satin black. Aft of the driver’s side front wheel, twin exhaust tips announce the fearsome new powertrain.

The full-width rear GT wing maximizes stability and downforce at high speeds, and continues the distinctive ‘><‘ DRL graphic identity established at the front of “Eximius 1.” The rear fascia also boasts large side air intakes which are connected by a dominant diffuser to manage underbody airflow.

Interior Design
An aura of intensity continues to the interior of “Eximius 1.” In concert with the exterior, blue-tinted carbon-fiber adorns the seats, flat-bottom steering wheel and doors; for aesthetics and weight-savings, all four doors are manufactured in exposed carbon fiber with one purposeful arm pad on each door. The seats, which are Recaro carbon fiber buckets up front, are trimmed with blue Alcantara and blue Italian leather with Moondust Alcantara upper sections, creating an articulated, form-fitted feel. To support high-speed driving and intense braking force, the accelerator, brake pedal and dead pedal are billet machined aluminum.

The instrument panel is reimagined in glossy carbon fiber and incorporates anodized billet aluminum HVAC vents. The carbon fiber center console is simplified to include the essentials only: the PRND gear selector, window switches, key fob holder, and Emergency kill switch. This console extends through to the rear compartment, to which the client’s custom-fitted carbon fiber racing helmet is held in place by a center-latched strap matching the blue seat belts.

By

BEIJING, Oct. 31, 2026 /PRNewswire/ — ModelBest and OpenBMB jointly announced the release and open-source availability of the MiniCPM-OCR series, a family of models for efficient document parsing and parsing-quality assessment. The launch includes two models: MiniCPM-OCR 1.0 (1.3B) and MiniCPM-OCR Jev (2B).

As the first OCR-focused model in the MiniCPM family, MiniCPM-OCR 1.0 brings top-tier parsing accuracy to a compact 1.3-billion-parameter architecture optimized for edge deployment, pushing forward the balance between efficiency and performance for open-source OCR models. Built for real-world conditions, it accurately parses scanned, photographed, curved, tilted and screen-captured documents without cumbersome image pre-correction, lowering the barrier to large-scale document digitization.

The model handles dense bilingual Chinese-English content, complex mathematical formulas, and multi-level or borderless tables, consistently performing at a leading level across a broad range of mainstream industry evaluations. Beyond full-page reconstruction, it supports key information extraction (KIE), pulling specified fields from invoices, IDs and financial statements according to business instructions.

Powered by DSpark decoding acceleration, MiniCPM-OCR 1.0 significantly increases end-to-end throughput while lowering per-page latency. For enterprises processing millions of pages—such as financial contract archives, academic libraries and government records—this means processing far more documents with the same hardware and time budget, at a substantially lower computing cost.

To address the long-standing need for page-by-page manual review, ModelBest and OpenBMB also introduced MiniCPM-OCR Jev, the first OCR result decision model that acts as an “AI quality inspector.” Rather than performing OCR itself, Jev compares the source image with OCR output and rapidly assigns confidence scores to text, LaTeX formulas and tables, detecting missing characters, errors and formatting misalignments. Despite its compact 2B-parameter size, Jev delivers judgment accuracy typically associated with far larger models.

Jev supports cross-model deployment and can be integrated into existing OCR workflows without replacing the underlying OCR engine. It can automatically identify reliable results for direct processing, flag potentially inaccurate outputs for human review and select the best result from multiple OCR systems. This enables enterprises to move from full manual inspection toward risk-based, automated quality control.
