Athina AI
What is Athina AI?
Athina AI is a collaborative development platform where teams build, test, and monitor production AI features in one workspace. It is built for mixed technical teams that need a shared place to iterate on prompts, datasets, evaluations, and live application behavior without handing every step to engineering.
The platform covers the loop from prototyping to production. Teams manage and version prompts, run experiments across models, evaluate outputs with preset or custom metrics, annotate datasets for human review, and monitor inference traces for cost, latency, and quality regressions.
Athina also offers Flows, a visual pipeline builder for chaining prompts, API calls, document retrieval, and custom code into deployable workflows. Enterprise options include self-hosted deployment in your own VPC, SOC-2 Type 2 compliance, and support for custom model providers such as Azure OpenAI and AWS Bedrock.
Teams at companies including Perplexity, You.com, Vetted, and PhysicsWallah use Athina to move AI features from experiment to production faster.
Stellaris AI
What is Stellaris AI?
Stellaris AI builds large language models marketed around native safety and human-like reasoning for real-world tasks. Its flagship SGPT line targets text and code generation, knowledge Q&A, logical reasoning, and analytics at a scale the company describes as hundreds of billions of parameters. The public site centers on a waitlist for SGPT-4.5 rather than a self-serve chat product you can open today.
Where many LLM labs bolt safety filters on after training, Stellaris AI frames safety as part of the model stack through strict source referencing and harm minimization in the architecture. It also highlights Real-time Context Learning (RCL) for adapting answers with live knowledge, a combination aimed at teams that want cited outputs instead of unchecked generation.
Researchers, enterprise AI teams, and early adopters join the SGPT-4.5 waitlist for first access. The company cites 10+ years of research and three core product pillars: Stellaris GPT, Native Safety, and RCL.
