Explore 16 more models by Anthropic →Claude Opus 5 is the flagship of Anthropic's Opus tier, released on July 23, 2026, and positioned as a generational upgrade for long-running agents, coding, and professional knowledge work over its predecessor, Claude Opus 4.8. It carries a one-million-token context window and 128K maximum output tokens, adds adaptive thinking for long-horizon reasoning, and retains strong multimodal vision and tool-use capabilities, including function calling and web search.
Anthropic frames Opus 5 as a step-change over Opus 4.8 rather than a raw-frontier leap, reporting improvements in agentic coding, professional knowledge work, and reasoning. A companion release, Claude Opus 5 Fast, targets latency-sensitive and cost-conscious workloads, giving deployers a lighter option within the same generation.
Opus 5 sits alongside recent siblings in the Claude 5 lineup, including Claude Sonnet 5 in the mid tier and Claude Fable 5, and it continues Anthropic's cadence of iterative Opus releases from Opus 4.5 through 4.8. For teams already building on earlier Opus models, it is a drop-in successor that keeps the same broad capability profile while extending context length and, per Anthropic, sharpening performance on demanding agentic and knowledge-work tasks.

"Best price" and the seller table are live AntSeed catalog data (advertised $/1M tokens — or $ per generated image for unit-billed image models — not settled amounts). Reputation = buyer trust score (0-100, the AntSeed SDK's own formula). "Routing" = the SDK's default buyer routing (what the VPR desktop app ships with): a trust ≥ 60 gate on the effective reputation, then cheapest-first among routable sellers; live failover state (per-peer cooldowns) is buyer-side runtime and not included. Model knowledge (TLDR, provider, About) via the VeniceStats enrichment layer. Advertised catalog, not the model used in any specific purchase. "Usage on AntSeed" counts only settlements whose buyers share the per-model split on-chain (metadata v2/v3, opt-in), so every usage figure is a lower bound.
