Introducing Gloy Dev 0.5 Exp

The model has 800 billion parameters and was trained on code and technical documentation through early 2025. This makes it one of the largest and most current coding models available.

How it works

You integrate Gloy Dev 0.5 Exp into your workflow through our REST API. Send a request with your coding task, and the model returns the code. It's that simple.

The model can generate everything from small functions to complete applications with thousands of lines of code. It understands context, follows best practices, and writes code that actually works.

Performance

Gloy Dev 0.5 Exp performs at a level comparable to Claude Sonnet 4 and GPT-5 Codex, outperforming other leading models across key metrics.

What makes it different

800 billion parameters: This is the largest model we've ever built specifically for coding. The size enables it to understand complex codebases, maintain context across thousands of lines, and generate sophisticated implementations.

Trained through early 2025: The model knows the latest frameworks, libraries, and best practices. It understands React Server Components, Next.js 15, TypeScript 5.x, Python 3.13, and other modern technologies that emerged in 2024 and early 2025.

API-first access: We provide a simple API that you can integrate however you want—into your CI/CD pipeline, your code review process, your internal tools, or anywhere else. We're also planning to release a VS Code extension to make integration even easier.

Generates large amounts of code: Unlike models that generate small snippets, Gloy Dev 0.5 Exp can write thousands of lines of coherent, production-ready code in a single response. Describe a complete feature, and it will implement it.

No filler, just code: The model provides complete, detailed implementations without unnecessary explanations or placeholder comments. Every response is thorough and production-ready.

What you can build with it

Because it's API-based, you can integrate Gloy Dev 0.5 Exp into any workflow:

• Automated code review bots that analyze pull requests
• Custom coding assistants tailored to your team's needs
• CI/CD integrations that generate tests or documentation
• Internal tools for rapid prototyping
• Legacy code modernization pipelines

Teams are using it to modernize legacy codebases, generate test suites, build prototypes, and automate repetitive coding tasks.

Languages and frameworks

Gloy Dev 0.5 Exp works with all major programming languages and frameworks:

Languages: Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, and more.

Frameworks: React, Next.js, Vue, Angular, Django, FastAPI, Flask, Spring Boot, .NET, Express, and many others.

The model understands modern patterns and best practices for each language and framework. It writes idiomatic code that follows current conventions.

Real-world examples

Response style

Gloy Dev 0.5 Exp is designed to provide comprehensive, detailed responses without unnecessary filler. When you ask for code, you get complete implementations—not brief snippets with "add more code here" comments.

The model writes long, thorough responses that cover all aspects of your request. It doesn't cut corners or leave parts unfinished. Every response is detailed, clear, and actionable.

This means you get production-ready code that you can actually use, not incomplete examples that require significant additional work.

Technical details

Gloy Dev 0.5 Exp uses a transformer architecture with 800 billion parameters. We trained it using a mixture-of-experts approach, where different parameter groups specialize in different aspects of coding—frontend frameworks, backend systems, data engineering, etc.

The training data includes code from millions of open-source projects, technical documentation, code reviews, bug reports, and Stack Overflow discussions. This helps the model understand not just what code does, but why it was written that way.

The model can maintain context across extremely long sequences, allowing it to work with large codebases and generate thousands of lines of coherent code.

API access

Gloy Dev 0.5 Exp is available exclusively through our API. We provide SDKs for Python, JavaScript, Go, and Java.

Here's a simple example in Python:

The API supports streaming for real-time generation, batch processing for multiple requests, and fine-grained control over generation parameters.

Pricing

Gloy Dev 0.5 Exp is priced at:

• Input: $10.00 per 1 million tokens
• Output: $20.00 per 1 million tokens

While this is higher than our standard models, the increased accuracy and ability to generate large, complex implementations often results in lower overall costs. A single request can generate what would take hours of developer time.

Comparison to other models

Gloy Dev 0.5 Exp performs at a level comparable to Claude Sonnet 4, one of the best coding models available. In blind tests, developers rated the two models as essentially equivalent in code quality.

What makes Gloy Dev 0.5 Exp unique is that it's specialized for coding. All 800 billion parameters are focused on software development, not general tasks. This specialization means deeper expertise in programming languages, frameworks, and software engineering practices.

Security and privacy

We don't train on customer data. Code you send to the API is used only to generate the response and is not retained or used for training.

All API communications use TLS 1.3 encryption. We offer SOC 2 Type II certified infrastructure with 99.9% uptime SLA. For organizations with strict requirements, we provide private deployment options.

Limitations

Like all AI models, Gloy Dev 0.5 Exp has limitations:

• It can make mistakes. Always review generated code before using it in production.
• It works best with clear, detailed prompts. Vague requests may produce suboptimal results.
• While it knows frameworks through early 2025, it won't know about changes after its training cutoff.
• Complex architectural decisions still benefit from human judgment.

We recommend using Gloy Dev 0.5 Exp as a tool to augment developers, not replace them.

What's next

This is just the beginning. We're working on:

• Expanding language support and framework expertise
• Improving the model's ability to learn project-specific conventions
• Adding capabilities for autonomous testing and documentation
• Developing specialized variants for ML, Web3, and DevOps
• Enabling multi-modal understanding (code + diagrams + screenshots)

Our goal is to make AI a seamless partner throughout the entire software development lifecycle.

Why API-only?

We chose to make Gloy Dev 0.5 Exp API-only for several reasons:

Flexibility: You can integrate it into any tool, workflow, or environment. No need to wait for IDE-specific plugins.

Scalability: The API scales from individual developers to enterprise deployments handling thousands of requests.

Future-proof: As new tools emerge, you can integrate immediately without waiting for us to build support.

Custom workflows: Build exactly what you need—code review bots, testing pipelines, documentation generators, or entirely new tools.

The API gives you complete control over how you use the model.

The model architecture

At 800 billion parameters, Gloy Dev 0.5 Exp is one of the largest models ever built specifically for coding. But size alone doesn't make a good coding model—architecture matters.

We use sparse attention mechanisms that allow the model to focus on relevant parts of large codebases. We use mixture-of-experts routing so different parameter groups can specialize. We use hierarchical transformers to understand code at multiple levels—from individual tokens to entire system architectures.

This architecture enables the model to maintain context across thousands of lines of code, understand complex dependencies, and generate implementations that are coherent from start to finish.

Training approach

We trained Gloy Dev 0.5 Exp on a carefully curated dataset that includes:

• High-quality code from millions of open-source projects
• Technical documentation and API references
• Code review comments and discussions
• Bug reports and their fixes
• Stack Overflow questions and answers
• Architectural decision records

This diverse training data helps the model understand not just syntax, but the reasoning behind code decisions, common patterns, and best practices.

We also used reinforcement learning from human feedback, where expert developers rated code quality, correctness, and adherence to best practices. This helps the model generate code that's not just functional, but maintainable and well-structured.

Context window and memory

One of Gloy Dev 0.5 Exp's key capabilities is its extended context window. The model can maintain understanding across hundreds of files and thousands of lines of code.

This means you can provide large amounts of context—your existing codebase, multiple related files, extensive documentation—and the model will use all of it to generate code that fits seamlessly into your project.

The model remembers relevant classes, functions, and patterns from earlier in the conversation, ensuring consistency across all its suggestions.

Code quality and consistency

When generating large amounts of code, maintaining quality and consistency is crucial. Gloy Dev 0.5 Exp is designed to ensure that the 5,000th line of generated code is just as well-structured as the first.

The model maintains consistent naming conventions, follows the same architectural patterns throughout, and ensures all components integrate correctly. It handles error cases, adds appropriate logging, and includes documentation.

This consistency means you can actually use the generated code without extensive cleanup.

Framework expertise

Gloy Dev 0.5 Exp has deep knowledge of modern frameworks and their ecosystems:

React: Understands hooks, Server Components, Suspense, and modern state management patterns. Knows when to use useCallback, useMemo, and other optimization techniques.

Next.js: Familiar with the app router, server actions, streaming, and caching strategies in Next.js 14 and 15.

TypeScript: Leverages advanced type system features including conditional types, mapped types, and template literal types.

Python: Writes idiomatic Python 3.13 code with proper type hints, async/await patterns, and modern syntax features.

FastAPI: Understands dependency injection, automatic OpenAPI docs, and async request handling.

Django: Knows the ORM, middleware, signals, and Django best practices.

The model generates framework-specific code that follows current best practices and conventions.

Debugging capabilities

Gloy Dev 0.5 Exp excels at debugging. Give it a stack trace, error message, or description of unexpected behavior, and it will:

• Analyze the error and identify the root cause
• Explain why the error is occurring
• Suggest fixes with explanations
• Consider edge cases and potential side effects

The model can trace issues across multiple files and understand complex interactions between components.

Refactoring at scale

Large-scale refactoring is risky. Gloy Dev 0.5 Exp makes it safer by understanding the entire codebase and making coordinated changes across multiple files.

The model can:

• Rename variables and functions globally
• Extract interfaces and abstract classes
• Break down large classes into smaller ones
• Update all call sites automatically
• Maintain functionality while improving structure

Teams have used it to refactor codebases with hundreds of thousands of lines of code.
