**Ana is live on the Anathema developer API** She is the second model in a small Anathema family. Lexi has convictions and sources. Ana builds your billion dollar CRUD app. She is a coding model built on one idea: **you should always be able to tell a checked answer from a plausible one.** After working with other foundation models, I realized they needed a lot more steering than standard harnesses and long AGENTS.md files could satisfy. Ana is steered to validate her work through test suites, research, and real execution. Rather than leaning on her priors, Ana RTFMs shit, so she isn't answering from stale docs in an ever-changing ecosystem. Ana has been calibrated to admit when she's wrong, check her work, flag unverified claims and admit when she doesn't know, rather than confabulate into a hole. She has: * A 900,000 token context window * Tool calling, including your own tool definitions * Vision, up to 8 images per request * Web research * A curated reference library * Code sandbox for running Python, JS, Bash, C, or Rust * strong capabilities for long-horizon workflows If you prefer to bring your own tools, as most harnesses have tools, that's fine. They'll thread in and replace hers. She runs on Kimi K3, with our persona, tool surface, and research stack on top. The API is OpenAI-compatible, so pointing an existing client at her is a base URL change. $5.50 /M input · $0.50 /M cached · $20 /M output anathema.ai/developers
