   OpenAI doubles flagship API token prices with GPT-5.5: $2.50/$15 to $5.00/$30 per 1M tokens

   OpenAI launched GPT-5.5 on April 23, 2026 (in the API from April 24) as its new flagship model, priced at $5.00 per 1M input tokens and $30.00 per 1M output tokens on OpenAI's official pricing page. That is a 2x increase over the prior flagship GPT-5.4, which sold at $2.50/1M input and $15.00/1M output. GPT-5.5 also resets the high end: GPT-5.5 Pro lists at $30.00/1M input and $180.00/1M output. Per-token efficiency gains do not offset the headline doubling; independent real-world cost analyses put the effective increase at roughly 49-92% versus GPT-5.4 depending on prompt length.

   Anthropic tested removing Claude Code from $20 Pro - reversed within 48h

   On Apr 21 2026 Anthropic ran a test removing Claude Code from the $20 Pro plan for ~2% of new signups; existing subscribers were not affected. The public docs and landing page were mistakenly updated site-wide, making it look universal. After backlash, Anthropic reversed it within ~48h and responded publicly.

   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.
