Starting today, you can use Anthropic's latest SoTA model, Claude Opus 4.6, in CometAPI's API and Claude Code (you can also use CometAPI's key to access Claude).

Claude Opus 4.6 is Anthropic’s newest “Opus”-class large language model, released February 2026. It is positioned as a workhorse for knowledge-work and research workflows — improving long-context reasoning, multi-step planning, tool use (including agentic software workflows), and computer-use tasks such as automated slide and spreadsheet generation. The release emphasizes enterprise readiness (security and safety testing), a beta 1-million token context window for very long documents, and higher “thinking budgets” via expanded output length.

Key advantages of Claude Opus 4.6

  • Much larger working memory (beta 1-million-token context): enables coherent work across many documents or very long files without frequent context juggling.
  • Stronger coding and agentic performance: improved planning, debugging, and “agent teams” that can split complex engineering workflows across specialized sub-agents. This makes Opus 4.6 particularly useful for sustained software tasks and automated pipelines.
  • Better tool and computer use: improved reliability when calling tools, composing spreadsheets or slides, and integrating search or external tools — reducing the number of manual revisions.
  • Enterprise readiness: Anthropic emphasizes safety, testing, and API controls that help teams deploy Opus 4.6 in production workflows.

Claude Opus 4.6 of Availability via CometAPI.

Claude Opus 4.6 is now offered through CometAPI’s unified model marketplace and playground, so developers can access Opus 4.6 through CometAPI’s single API (consistent authentication, pricing tiers, and SDKs). This makes it straightforward to swap Opus 4.6 into existing apps that already use CometAPI’s multi-model interface.

Furthermore, the price of Claude Opus 4.6 on Cometapi is 20% of Anthropic.

If your project needs long-context reasoning, robust code generation/maintenance, or multi-agent automation, Opus 4.6 is a step up — and with CometAPI support you can trial or integrate it without changing your overall API stack.
