New Service For Embedded Engineering

Fixstars Vega

A secure AI appliance for embedded software development teams

Accelerate development with open-weight LLMs while keeping your code confidential — with Fixstars engineers alongside you from secure setup through team-wide adoption.

Foundation

What it takes to run AI
inside an embedded team

Cloud AI is tempting. But your source code, designs, and customer specs can't leave the building.
You need an AI environment built around three pillars — security, performance, and team adoption.

Security

Protect what is yours

Source code, design documents, specifications, customer data — none of it touches an external AI service.

Quality

Performance you can ship

Running in development isn't enough for production. We optimize AI-generated code to the performance your embedded devices demand.

Productivity

AI for the whole team

Not just power users. Policies, training, and operations make AI part of how the team works.

Get Started

We'll design a configuration
that fits your environment and security requirements.

Use Case

Where AI fits
in the embedded workflow

Combine AI chat, coding agents, and internal knowledge — and AI shows up across investigation, implementation, review, testing, and maintenance.

Understand legacy code

Map control logic, drivers, and middleware structures fast.

Reference specs and design docs

Surface related specs and past design decisions from your internal documents.

Generate and refactor code

Write and revise C/C++, Python, test code, and build scripts.

Review with rules in mind

Reviews shaped by your coding conventions, design rules, and past bug patterns.

Author tests and debug

Unit tests, edge cases, log analysis, root-cause investigation.

Improve performance

Bottleneck analysis and improvement proposals for models and code.

Security

Multiple deployment modes,
one secure stack

We combine open-weight LLM execution environments with closed-model access — sized to your data sensitivity and internal policies.

Open-weight LLMs — execution

On-premises

On-premises

We build dedicated hardware inside your facility. Code never leaves the premises.

Hosted private cloud

Hosted private cloud

We build and operate dedicated hardware in a partner data center. Less ops on your side.

Cloud-based VPC

Cloud-based VPC

We build a dedicated VPC environment on a cloud vendor's infrastructure. Lower upfront investment. Start in weeks, not months.

Closed models — access

Cloud AI services like Amazon Bedrock

Cloud AI services like Amazon Bedrock

Run the latest closed models — Claude, GPT-5.x, Nova, and others — in your own virtual private cloud. Your data is never used to train someone else's model.

Access Control

Model selection based on code sensitivity

The Model Orchestrator securely routes requests to the appropriate model based on your security policy.
Available AI models can be controlled based on code sensitivity. For example, customer code that cannot be sent to the cloud can be restricted to Internal Local AI only.

Available AI environments, managed by security level

  • Level 0

    External Cloud AI

    Training may be used

  • Level 1

    External Cloud AI

    Not used for training

  • Level 2

    Internally Managed Cloud AI

    (Closed AI via Amazon Bedrock)

  • Level 3

    Internal Local AI

Tell us your environment and operational policy,
and we'll propose the right configuration.

Quality / Models

Production-ready models,
matched to the task

We raise AI development quality across three dimensions — model selection, output code performance, and organizational knowledge. Starting with model selection: the right model depends on the task, security envelope, and quality bar. We continuously evaluate models and deliver a catalog matched to your work.

Open-weight models are a real option now

Open-weight models have advanced enough to be a practical choice — even on-prem or in closed networks. For work where code can't leave the company, they often perform well enough.

Open/closed-weight LLM benchmark performance

Response times, engineered

Running an open-weight model as-is may not deliver production-ready performance. Fixstars Vega ships models with performance engineering applied by default.

Time to first token (TTFT P90)

Before optimization long queues
~59 sec
After optimization virtually no queueing
~3.8 sec (low response times even at 90 concurrent users)

Measured by Fixstars on GLM-5.1 (results on GLM-5.2 forthcoming), 8x NVIDIA H200 GPUs. See the service brief for detailed results.

Validated models we provide

You don't have to evaluate models from scratch. Our engineers validate each one on real embedded development projects and hand it over with use cases, performance, and licensing already mapped out.

Models we provide

GLM-5.2

  • A top-performing open-weight model for coding tasks
  • Long-context support, well suited to large codebases
  • Best for text-based work such as code generation and analysis

Qwen3.6-27B

  • A relatively lightweight 27B model with practical coding performance
  • Multimodal input, including images and video
  • Useful for document analysis and work involving screens and diagrams

As of July 2026. Available models are updated continuously. GLM-5.2 availability may depend on your hardware configuration.

The right model for each task type

Different tasks suit different models — spec writing from text alone, E2E testing that needs image input, and so on. You can configure the assignment per agent.

Example model assignment per task

AI model assignment by task type
Quality / Code Optimization

High-performance output code,
powered by a performance-engineering harness

Fixstars Vega's performance-engineering harness packages more than 20 years of know-how from embedded development projects into a form AI agents can apply. The code it produces matches — and in some projects exceeds — the optimization work of veteran engineers.

Capabilities

tune

General performance optimization — automatic rewriting for CPU-GPU sync reduction, memory layout, torch.compile, and more.

convert

TensorRT acceleration for PyTorch inference — automatic, functionally equivalent rewrites that avoid graph breaks.

tune-discover

Discover new optimization patterns — the LLM autonomously finds and accumulates novel optimizations not in the existing playbook.

* More capabilities are added on an ongoing basis.

Quality / Knowledge

Bring your team's knowledge
into the AI

We apply our knowledge-loop methodology to your organization, raising development quality across the team. Throughout the engagement, we build the mechanisms for AI to reference your veterans' know-how and internal standards.

Know-how and rules AI will reference

01

Coding conventions & design policies

Naming rules, design judgments, quality criteria — the team-wide ground rules.

02

Operating procedures

How routine work — reviews, code analysis, documentation — gets done.

03

Project-specific rules

Role assignments, decision criteria, the reasoning behind past decisions.

* At launch, we support the setup. Through the project, your knowledge base grows.
