TL;DR Sakana AI dropped Fugu Ultra on June 22, a 7B orchestrator that beats Claude Opus 4.8 and GPT-5.5 on SWE-Bench Pro by routing tasks across frontier models; GPT-5.6 launch window opened this week with June 25 flagged as the likely date.

Models & research

  • model-releases Sakana AI launched Fugu and Fugu Ultra on June 22: a 7B RL conductor model that routes sub-tasks to a pool of Claude Opus 4.8, GPT-5.5, and Gemini 3.1 Pro, then synthesizes the results. Fugu Ultra scores 73.7 on SWE-Bench Pro (vs. Opus 4.8 at 69.2 and GPT-5.5 at 58.6), 95.5 on GPQA-D, through an OpenAI-compatible endpoint at $5/M input / $30/M output. Not available in EU/EEA. Fable 5 and Mythos are not in the pool because the US killed their access on June 12. The Decoder · MarkTechPost

  • model-releases GPT-5.6 launch window opened Monday June 22 per OpenAI’s internal timeline; a separate leak pegs June 25 as the drop date. Claimed features: 1.5M-token context (up from 1M in GPT-5.5), reasoning effort budget raised from 768 to 960, December 2025 knowledge cutoff. Still no official announcement or API string as of tonight. TechTimes June 21 · Geeky Gadgets
