Iceman Contributor Free Is Unlimited on OpenCode Go

OpenCode Go has added Iceman Contributor Free, a mystery reasoning model with unlimited usage for a limited time. It supports tool calling and has a reported 262K-token context window, but its creator is undisclosed and there’s no reliable public benchmark proving it beats other coding models.

It isn’t free without conditions. You need an OpenCode Go subscription, starting at $10/month. OpenCode’s listing says the offer is temporary, and prompts and completions may be used to improve the model. Check current terms before sending private code.

Compared with Beam 1.0 (opens in a new tab), another limited-time free option, Iceman has a smaller reported context window and less transparency about its origin. Early community feedback is mixed, and users have reported tool-call failures. Community report (opens in a new tab) · Tool-call issue (opens in a new tab)

Verdict: worth a cautious test if you already pay for Go. Not a reason to subscribe on its own. Verify diffs and test results; don’t assume unlimited means dependable.
