Deep Cogito: Cogito v2.1 671B

Cogito v2.1 671B is a text-only model from Deep Cogito with a 128,000-token context window and built-in reasoning support. It does not support tool use, and structured output availability is unconfirmed, so workflows that depend on either should look elsewhere. The model accepts only text input, which limits its fit for multimodal tasks. On the comparison side, pricing is symmetric at $1.25 per million tokens for both input and output, which is competitive for a large-scale reasoning model. The significant caveat is that there is no independent benchmark coverage yet, so performance claims are unverified. Buyers who want reasoning at a moderate price point may find it worth testing, but anyone making a data-driven model selection should wait for third-party evaluation results before committing to it in production.
