THE PRODUCT, BEYOND THE PITCH
Editorially reviewed · Sources checked Sep 10, 2026
A good fit for
- Teams requiring guaranteed latency and dedicated resources with private fine-tunes and SLA.
Know the limitations
- Developer plan concurrency can be exhausted by agents that fan out aggressively, causing errors.
- This model may produce sensitive or inappropriate content due to reduced safety filtering and is recommended only for research or controlled environments.
What you can do
- Roleplay, stories, and long conversations via chat interface.
- Coding agents and API traffic for production applications.
- Ideal for complex reasoning tasks requiring deep logical analysis and problem-solving.
- Suitable for agentic workflows involving planning and multi-step execution.
- Effective for coding tasks, achieving high scores in benchmarks like LiveCodeBench and Codeforces.
Features
- Support for large context windows up to 256K tokens for advanced reasoning and agentic workflows.
- Hybrid Attention Architecture combining Compressed Sparse Attention and Heavily Compressed Attention to improve long-context efficiency and reduce inference costs.
- Three reasoning effort modes: Non-think for fast responses, Think High for logical analysis, and Think Max for maximum reasoning.
Integrations

A practical workflow
- Subscribe to a plan to receive an API key that works with OpenAI-compatible frontends like SillyTavern, RisuAI, or Wyvern.
- If a model is temporarily at capacity (HTTP 503), switch to a sibling model or retry; no charges occur for failed requests.
