Its pricing page now says $100 paid unlocks 50 concurrent sessions; it said $200 when ColdTally captured the baseline earlier on 2026-10-17. The other tiers listed are $1,000 for 250, $5,000 for 500 and $25,000 for 1,000. The free starting point is still 10 concurrent sessions, and per-hour and per-minute rates are unchanged.

Blaxel says the platform keeps running and existing API keys and credits remain valid, and that Baseten will add new products based on Blaxel's primitives over time. ColdTally rechecked Blaxel's pricing page and Terms and Conditions on 2026-10-17: no price, tier or free-credit changes, and the terms are still the December 10, 2025 version, including restriction (f) on publishing benchmarks, so Blaxel stays pricing-only here.
