OpenCode’s free DeepSeek V4.1 Flash option gives developers a way to use the model without spending OpenCode Go credits. The trade-off is a smaller context window: 200,000 tokens for the free version, compared with 1 million for the full version. 2

What changes for OpenCode users
OpenCode announced the free option on October 15, 2026. Calls to the free model no longer count against Go plan credits, and OpenCode lists it as a separate model, deepseek-v4.1-flash-free. 2
28
That removes the credit cost within OpenCode, but it does not make the free and full-context versions identical. The model listing gives the free version a 200K-token context and the full version a 1M-token context. A shorter window leaves less room for source code, conversation history, and tool output in a single task. 23
From a larger allowance to free access
The change follows OpenCode’s “Operation Cheepseek” promotions. In September, the DeepSeek V4.1 Flash allowance in OpenCode Go was temporarily raised from $15 to $60, then increased to $80 on October 12. The free variant subsequently made calls no longer count against the plan allowance. 4
The offer is for use inside OpenCode, not a general free DeepSeek API tier. Reporting as of October 16 says DeepSeek’s own API remains paid. 10 DeepSeek announced V4.1 Flash on September 10 and listed API support for the model.

What to know about limits, duration, and speed
The offer has been described as limited-time, but the available reports do not give an end date or a specific usage cap. Treat access as subject to change rather than assuming it will remain free indefinitely. 3
17
Speed reports are anecdotal, not a controlled comparison. One report relays user feedback about variable generation speeds, including roughly 50 tokens per second at 200K context. That does not establish typical performance, prove slowdowns as context grows, or show that a paid route is consistently faster. 9
When the free version makes sense
The 200K option is a reasonable place to start when avoiding Go credit use matters and the task fits within the smaller context window. For a large repository or a long agent session that needs more context, the full 1M-token version offers more room—but the available evidence does not guarantee that paying will deliver more predictable speed. 17
23
Bottom line: OpenCode’s free variant is a credit-saving option with a material context trade-off. Check the current model listing and terms before relying on it for long-running or large-codebase work.
