July 2026

  • Meta Muse Spark 1.1 — Released July 9, 2026 in public preview through Meta Model API. Meta positions Spark as a 1M-token multimodal model for long-context creative workflows; no public API price was posted in the announcement, so benchr tracks it in model-figures.json but keeps it out of the ranked pricing tool for now. Source: Meta.
  • Grok 4.5 — Released to the xAI API July 8, 2026. xAI lists grok-4.5 with a 500K context window at $2 input, $6 output, and $0.50 cached input per 1M tokens. xAI does not publish official benchmark tables or a max-output limit for this model yet. Source: xAI. benchr pricing.
  • GPT-5.6 — generally available — July 9, 2026. OpenAI's API changelog now lists GPT-5.6 Sol, Terra, and Luna as released to the API. Official prices are unchanged from the June preview: Sol $5/$30, Terra $2.50/$15, Luna $1/$6 per 1M; OpenAI's models page lists all three with 1.05M context and 128K max output.

  • Claude Sonnet 5 — Released July 1, 2026. Anthropic's second Mythos-class-architecture model after Claude Fable 5, priced at an introductory $2/$10 per million tokens through August 31, then $3/$15 from September 1, with a 1M context window and a 128K max output — double Sonnet 4.6's 64K. SWE-bench Verified 89.4% edges out Claude Opus 4.8's 88.6%, though Opus 4.8 still leads on GPQA Diamond (93.6% vs. 92.0%). Same safety-classifier fallback behavior as Fable 5.

  • Claude Fable 5 restored to all customers — July 1, 2026. The U.S. Commerce Department export-control review that suspended Fable 5 on June 12 concluded, and Anthropic restored access for every customer, with AWS restoring Bedrock access the same day; Claude Mythos 5 remains limited to Project Glasswing.

  • Claude Fable 5 and Claude Mythos 5 — Released June 9, 2026. Fable 5 is the first Mythos-class model anyone can use: $10/$50 per million tokens, 1M context, 128K max output, with safety classifiers that fall back to Opus 4.8 on offensive-cyber, most bio/chem, and distillation requests. Mythos 5 stays restricted to Project Glasswing. Source: Anthropic. benchr coverage. Update June 13: both models were suspended for all customers on June 12 under a U.S. Commerce Department export-control directive (no use by any foreign national); Anthropic said it was working to restore access. Update June 26: Mythos 5 was cleared for limited redeployment to vetted US critical-infrastructure organizations; Fable 5 remains suspended for all customers.

What to watch

Claude Fable 5's return — resolved. The export-control review Commerce opened in June concluded on July 1, 2026, and Anthropic restored Fable 5 to all customers, with AWS restoring Bedrock access the same day. Claude Mythos 5 remains limited to Project Glasswing.

Next up. GPT-5.6 is now GA. Gemini 3.5 Pro has not been released, and benchr is watching whether Project Glasswing widens beyond its current vetted-partner list for Claude Mythos 5.

The open-weight tier (DeepSeek V4, Qwen 3.5/3.6, Mistral Medium 3.5) has closed the gap with closed labs to single-digit benchmark points on most evaluations. Coding and reasoning leaders are now distributed across both camps.
