Anthropic releases Opus 5.5 with improved performance and lower pricing

Anthropic announced Opus 5.5, a faster and cheaper follow-up to Opus 5 that the company says outperforms the larger Fable model on many coding and knowledge-work benchmarks. Output token pricing has been reduced (now $20 per mTok vs $25 for Opus 5), the model communicates with less jargon and front-loads key information, and Sonnet 5.5 and Haiku 5.5 are slated to follow soon; the release is subject to the same safety safeguards as Fable and underwent external evaluation.

SpaceXAI releases Grok 4.7 — faster, cheaper model for coding and knowledge work

SpaceXAI released Grok 4.7, a new base-model upgrade positioned as its most capable model for coding and knowledge work; it reportedly uses a larger base model, longer RL training focused on long-running tasks, and an entirely new safeguard stack. The company says Grok 4.7 matches the price and speed of Grok 4.6 while improving verification, longer-context handling, document/presentation generation, benchmark performance (CursorBench 4.0, GDPval, AA Briefcase), and safety metrics (LatchBio biosafety 62.4%, HackerBench v0.3 allowing 3.3% risky prompts); it is available in Cursor, Grok Build, the Grok API, third-party harnesses and cloud platforms, priced from $2 per million input tokens and $6 per million output tokens, with an optional faster (2x) variant at double the price.
