DeepSeek-V4-Flash is now officially available for limited-time free and unrestricted use on B.AI! Web Chat and API are both synchronously open, allowing you to fully experience everything from running code, scheduling Agent agents, long text processing, to high-concurrency workflows.
đ Experience Path
đ Web users: select DeepSeek-V4-Flash from the model list after logging in, chat freely
đ§ Developers: choose "Full Access" under "Official" mode in the API management panel, create an API Key, copy the model ID for integration
đ§ Breaking Down "Reverse Free Access" as a Specific Claim
This is the actual launch confirming what was previously announced as a countdown, DeepSeek raised its own prices dramatically, up to 1,100% depending on model and timing, and B.AI is now officially reversing that in the opposite direction, from a real price increase back to zero cost. "Reverse" is doing precise work here, this isn't just a discount off an already-stable price, it's a full offset against a confirmed, dated hike from the model's own provider.
đ My Take
The two access paths described here are worth reading as genuinely equal in capability, not a limited web trial paired with a more restricted API tier. "Full Access" under Official mode specifically, plus Web Chat opening synchronously, means developers building real integrations get the same zero-cost access as someone just chatting casually. That's a meaningfully stronger commitment than platforms that typically reserve their most generous free tiers for the lower-stakes web interface while metering API usage more tightly.
"Unrestricted" paired with "limited-time" is worth holding as two separate claims, capability isn't limited during this window, but the window itself is. Worth treating this as a genuine, time-sensitive opportunity to build and test against this specific model at zero marginal cost, not a permanent pricing structure.
đŻ What I'd Actually Check
How long "limited-time" actually extends, and whether B.AI provides advance notice before reverting to standard pricing, that timeline matters for anyone planning to build a production integration during this specific free window versus someone just testing casually.
