NEAR AI Cloud has added three Anthropic models to its platform: Claude Sonnet 5.5, Claude Opus 5.5, and Fable 5.1, expanding the selection of frontier large language models available to developers and teams building on the NEAR ecosystem's cloud inference layer.

The additions were announced by the NEAR Protocol team in an official post on X, confirming that all three models are now accessible through NEAR AI Cloud. The announcement names the models exactly as Claude Sonnet 5.5, Claude Opus 5.5, and Fable 5.1 — the last being Anthropic's narrative and creative reasoning model within the Claude family.

NEAR AI Cloud Expands Its Model Lineup

NEAR AI Cloud is the protocol's hosted inference and AI services layer, positioned to give developers a unified access point for large language model inference without requiring API contracts with each provider. By adding Anthropic's latest Claude models, the platform now carries some of the most capable commercially available LLMs. That matters for ecosystem builders because hosted inference endpoints are the standard route through which applications embed LLM features — assistants, summarization, agentic workflows — so a platform's model lineup directly shapes what teams can ship without opening accounts with external providers.

The models added are:

• Claude Sonnet 5.5 — Anthropic's mid-tier reasoning and instruction-following model.
• Claude Opus 5.5 — Anthropic's highest-capability model in the 5.5 generation.
• Fable 5.1 — Anthropic's narrative and creative reasoning model.

Fable 5.1 is a notable addition given its orientation toward long-form reasoning and structured narrative output — workloads that differ meaningfully from standard code generation or retrieval tasks. Its presence on NEAR AI Cloud suggests the platform is targeting a broader range of inference use cases, not just developer tooling.

What the Update Changes for Platform Users

Having Sonnet 5.5, Opus 5.5, and Fable 5.1 available through a single cloud endpoint reduces the integration overhead for teams that need to route different task types to different model tiers. Developers can assign a lighter model to high-volume, low-complexity tasks and escalate to Opus 5.5 for deep reasoning without switching providers.

The announcement, however, does not specify pricing tiers, rate limits, or regional availability, nor does it clarify whether access is gated behind NEAR token staking or payment in NEAR. Those details have not been confirmed in available materials, and users should consult NEAR AI Cloud's official documentation for current access terms.

Broader Context

NEAR Protocol has been active on multiple fronts recently. The protocol's Intents layer previously demonstrated its capacity to intercept and block suspicious flows linked to the Bitget incident, signaling infrastructure maturity that extends beyond AI compute alone.

The integration of Anthropic models also reflects a wider pattern in the decentralized AI compute space, where blockchain-native cloud platforms compete to offer access to the same frontier models as centralized providers, differentiating on payment rails, data sovereignty, and on-chain programmability rather than model capability itself. Anthropic's Claude family is already reachable through several major centralized clouds, so listing a given model is increasingly a baseline expectation, and the differentiation shifts to how access is packaged and paid for. Whether NEAR AI Cloud exposes these models through smart contract-callable APIs or purely off-chain endpoints remains to be clarified by the team.
