DeepSeek ships V4 and sets a hard Jul-24 retirement for the deepseek-chat / deepseek-reasoner model names
On April 24, 2026 DeepSeek launched V4 - deepseek-v4-flash and deepseek-v4-pro, with 1M-token context as the new default and open weights under MIT - and announced that the legacy deepseek-chat and deepseek-reasoner model names will be fully retired and inaccessible after July 24, 2026 15:59 UTC. After that cutoff, calls using the old names error with no grace period. Migration is a one-line model-name change and pricing actually improves for most callers, so this is an upgrade with a deprecation deadline rather than a downgrade - the watch item is anything still pinned to the old names.
Predicted impact: 15-30% of paid users · ~$2-$18 per user

DeepSeek V3 API output token price doubles after launch promotion ends
DeepSeek's V3 API launched with promotional pricing of $0.28/M output tokens. Two months later that doubled to $0.55/M with one week's notice. Still cheap relative to GPT/Claude, but doubled is doubled.
