Mistral AI

Mistral AI develops a wide spectrum of AI models and services, enabling developers, researchers, and businesses to build, deploy, and fine-tune large language and multimodal models.
The company focuses on open weights, reasoning capability, multimodality, and enterprise-grade features such as long context windows, domain-specific deployments, and fine-tuning options.

Mistral Models

Mistral divides its lineup into open models (weights freely available) and premier models (API-first, enterprise-grade).
Here are the most important families:

  • Mistral 7B – Compact, open-weight dense model for efficient deployment.
  • Mixtral 8×7B / 8×22B – Sparse mixture-of-experts models balancing performance and cost.
  • Mistral NeMo 12B – Strong open-weight model for multilingual and reasoning tasks.
  • Codestral – Code-oriented models for software engineering and developer tools.
  • Pixtral – Multimodal family supporting text + image inputs (e.g. Pixtral-12B, Pixtral Large).
  • Magistral – Reasoning-focused models; Magistral Small (open-weight) and Magistral Medium (enterprise).
  • Mistral Medium 3 / 3.1 – Premier multimodal models with ~131K context length, enterprise-grade APIs.
  • Mistral Large / Large 2 (123B) – Very large dense models with long context, available via API.
  • Specialized Models – OCR models (e.g. mistral-ocr-2503), embeddings, moderation, and speech (Voxtral).

Video Captioning Agent

Video Captioning Agent

This project is a Dockerized AI agent that automatically generates stylistically diverse captions for video clips using a two-stage prompting pipeline. Built for the AMD Pervasive AI Developer Contest, the agent reads video captioning tasks from a JSON input file, processes each video through multimodal AI analysis, and produces captions in four distinct tones: formal, sarcastic, humorous-tech, and humorous-non-tech. The architecture follows a producer-consumer pattern with model pooling to maximize throughput while respecting free-tier API rate limits across multiple providers. Stage 1 (producers) uses two Gemini 2.5 Flash instances from separate Google Cloud projects to concurrently generate objective video descriptions. Each video is downloaded, keyframes are extracted locally via ffmpeg, and the frames are sent to Gemini's multimodal API for factual content analysis. Descriptions are pushed into an asyncio.Queue that bridges the two stages. Stage 2 (consumers) employs three text-to-text models — Groq Llama 3.3 70B, Mistral Small, and Gemini 3.1 Flash Lite — managed as a rotating pool. When a description arrives in the queue, an available caption model is popped from the pool, generates all four styled captions, then re-enters the pool after a 5-second cooldown to avoid rate limiting. This design distributes load across independent providers with separate quotas, eliminating single-point-of-failure rate limit issues. The system is fully config-driven through a JSON file specifying providers, models, API key references, and cooldown parameters. All provider implementations share abstract base classes (DescriptionProvider, CaptionProvider), making it trivial to add new models. The agent handles failures gracefully with retry logic (exponential backoff), keyframe fallback when video upload fails, and partial result writing if the 8-minute runtime threshold is reached. The Docker image targets linux/amd64 on python:3.11-slim with ffmpeg included.

ARIA - Automated Research Intelligence Agent

ARIA - Automated Research Intelligence Agent

ARIA (Autonomous Research Intelligence Agent) is a multi-agent pipeline that turns a clinical question into a rigorously synthesized, citation-backed answer, then interrogates its own sources for integrity issues most researchers never have time to check by hand. The core pipeline runs five stages: a Query Architect generates MeSH-optimized search strategies, a Literature Scout retrieves matching papers from PubMed and Europe PMC, a PRISMA Filter screens for relevance, an Evidence Synthesizer builds a structured, cited synthesis, and a Citation Builder formats references. The result is a clinical-grade literature review complete with a comparison table, PRISMA exclusion log, and predictive forecasting of where the evidence is heading. What sets ARIA apart is its Integrity Audit layer, five independent detection agents that stress-test the synthesis itself: a Citation Ghost Detector flags citations that don't actually support their attached claims, a Methodology Drift Tracker catches when a paper's results section doesn't match its stated methods, a Confidence Calibration Check flags language stronger or weaker than the underlying data supports, a Cross-Paper Contradiction Finder surfaces where cited studies genuinely conflict rather than just differ in topic, and a Reproducibility Score grades whether a study reports enough detail to be redone. Each runs in parallel against the same papers already retrieved, no extra fetching, and renders as color-coded, explainable flags across two views: internal consistency and external validity. Built on LangGraph for orchestration and Qwen2.5-72B served via vLLM on an AMD MI300X, ARIA treats research synthesis and research auditing as one system, not two separate tools.
