OpenCode opens DeepSeek V4.1 Flash for free, capped at 200K context

KEY FACTS

OpenCode announced on October 15 that DeepSeek V4.1 Flash is available for free.
The free tier's measured context window is 200K, below the 1M version.
After the free rollout, calls to this model no longer count against OpenCode plan quota consumption.
Previously, the quota was raised from $15 to $60 in September, then adjusted to $80 on October 12.
The model launched on September 10 and is a 552B-parameter native multimodal MoE model.

PHYSIX OBSERVATION

Opening it for free can quickly pull in new users, but the 200K context cap exposes the pressure of inference costs. User feedback points to large TPS fluctuations and clear slowdowns on long contexts, which shows that if the free strategy cannot stabilize the experience, it will instead burn developer trust. Beyond model capability, service stability is becoming a key variable in platform competition.
