Intelligence, Your Choice.
Explore the AI models supported by CodeXa Studio IDE. Every model is accessible across Starter, Plus, Pro, and Max tiers.
NEXA Edge
Locally compiled quantized weights running on your CPU or GPU without transmitting code to external servers. Ideal for air-gapped security and offline travel.
- Single-file method autocompletion
- Local syntax transformations
- Zero-telemetry air-gapped development
CodeXa AST Models
Trained exclusively on AST symbol relationships and syntax trees for ultra-fast symbol renaming, reference lookups, and type checking across large repositories.
- Cross-file symbol indexing
- Monorepo reference graph caching
- Syntactic diff validation
Gemini 3.6 Flash
Exceptional speed-to-intelligence ratio with a massive 1-million-token context window. Highly efficient for broad file searches, multi-file reviews, and quick question answering.
- Rapid multi-file search
- Real-time chat queries
- Large context window documentation analysis
Gemini 3.8 Flash
Upgraded multimodal model delivering sharper architectural understanding and code diff accuracy with sub-second response times across large workspace contexts.
- Complex component generation
- Refactoring legacy code
- API contract harmonization
GPT-6 Astra
Official OpenAI GPT-6 Astra integration (model id: gpt-6-astra). Translates high-level feature specifications into atomic diff plans and multi-file orchestrations with verified semantic correctness.
- Architectural feature planning
- Multi-file refactoring runs
- Autonomous agent swarms
Fabel 5.1 Verification
Acts as the automated QA engineer in the dual-agent loop. Verifies that generated code hunks do not violate TypeScript invariants, break lint rules, or cause regression.
- Pre-commit diff validation
- Invariant checking
- Automated test generation
GPT 5.6 SOL
Specialized for kernel bindings, low-level concurrency, cryptographic implementations, and distributed systems logic requiring maximum reasoning depth.
- Distributed systems architecture
- Memory management & concurrency
- Mathematical algorithms
OPUS 5.5
World-class reasoning capabilities tailored for massive monorepo migrations, enterprise security boundaries, and complex domain-driven software design.
- Monorepo architectural overhauls
- Domain-driven design
- Security auditing
