OpenCode says LongCat 2.5 is free on its platform for two weeks, with a 1M-token context, multimodal input and zero data retention, according to @opencode. It drops the word "Preview" from the name, and an earlier OpenCode post announced LongCat-2.5-Preview as free for two weeks, so this may be a repeat of that offer.

What the model is

Daily.dev reports that LongCat-2.5-Preview was released on September 25, following the open-sourced LongCat-2.0 from late June. The model is a mixture-of-experts design with about 1.6 trillion total parameters and about 48 billion activated, and it adds image understanding and support for long-horizon, multi-app workflows, according to Daily.dev. The same write-up says it supports a 1-million-token context window with a 128K max output and is API-compatible with Claude Code, OpenCode, OpenClaw, Hermes and Kilo Code.

Meituan's LongCat team posted separately that the preview is free to try on OpenCode for two weeks. The September launch came with no benchmarks, according to Zavino, and our earlier report on the 1.6T agentic launch covers the model itself.

Price and access

The Pi model page lists the model with text and image input, reasoning support, a 1,000,000-token context window and a 131,072-token max token limit. Its input, output and cache prices are $0 under the OpenCode Go provider.

LiteLLM's model page lists it as free to use on OpenCode Go under the name opencode_go/longcat-2.5-preview-free, as of November 9, 2026. LiteLLM added the model to its price file on October 24.

A third-party blog quotes OpenCode's free-model notes as saying the model is free for a limited time. A separate write-up says OpenCode did not state a calendar end date, usage cap or eligibility limit. Daily.dev reports Meituan's own offer as a 5-million-token free quota for existing users.

What to watch

Whether the current window is new, when it ends and what the model will cost after it are the points readers should check on OpenCode's own pages before building on it.

Our read: the draw for coding-agent users is the combination of a 1M-token context and zero data retention at no charge, but the end date is the detail to confirm first.
