This weekly recap covers major AI developments: OpenAI's public launch of GPT-5.6 family (Sol, Terra, Luna) and voice model GPT-Live-1, xAI's Grok 4.5, Google's Gemini 3.5 Pro delay, Microsoft's low Copilot conversion rate (4.5%), DeepSeek API retirement, Meta's Muse Image, and Ollama's funding.
Big week, so a consolidated rundown for anyone catching up. OpenAI released the GPT-5.6 family publicly on July 9 after a limited partner preview — Sol (frontier reasoning), Terra (previous-flagship performance at ~2x lower cost), Luna (fast/cheap). They also shipped GPT-Live-1, a full-duplex voice model that handles simultaneous listening/speaking, plus gpt-realtime-2.1 with ~25% lower p95 latency. xAI launched Grok 4.5 (trained alongside Cursor) at $2/M input and $6/M output, claiming Opus-class performance on coding/legal/finance tasks. Independent evals aren't in yet, so treat the claims accordingly. Google delayed Gemini 3.5 Pro to July 17 — full architectural rebuild, 2M context. Separately, four senior DeepMind researchers departed in one week (Shazeer to OpenAI; Jumper, Adler, Pritzel to Anthropic), and Alphabet dropped ~$225B in market cap. Microsoft is merging its Copilot apps into one by August. The notable disclosure: fewer than 4.5% of 450M M365 seats have converted to paid Copilot. Meta launched Muse Image, its first Superintelligence Labs model — agentic image gen that invokes search/code tools and self-refines. Trains on public Instagram photos by default (opt-out). Open source: Ollama raised $65M Series B (8.9M monthly devs). Gemma 4 got ~90% faster on Apple Silicon in Ollama via multi-token prediction. And a PSA — DeepSeek retires deepseek-chat and deepseek-reasoner on July 24. One-line migration, but note deepseek-reasoner maps to v4-flash thinking mode, not v4-pro, so heavy reasoning workloads should evaluate v4-pro explicitly rather than trusting the alias. My take as someone building on top of these APIs: the simultaneous price drops (Terra, Grok 4.5, Sonnet 5's intro pricing) matter more than any single benchmark. Near-frontier inference costs fell across four vendors in one week, which changes what's economically viable to automate. Meanwhile Microsoft's 4.5% suggests horizontal assistants aren't converting even with unlimited distribution — the demand seems to be for task-specific automation, which matches what I see with SMB clients. And the DeepSeek cutoff is a good reminder to abstract your model layer. Sources: OpenAI/xAI/Meta blogs, Euronews, Bloomberg, TechCrunch, CNBC, TechTimes coverage this week.
Multiple AI model releases are delayed: GPT-5.6 now expected mid-July, DeepMind's 3.5 Pro postponed, while OpenAI's Bidi voice model and Claude Sonnet 5 for enterprises see progress.
Openai is reportedly preparing GPT-5.6 for release next week, with three tiers (Sol, Terra, Luna) and a new reasoning-effort control slider in the Codex app, potentially challenging Anthropic's Fable 5.
OpenAI announces GPT-5.6 preview, a new family of models (Sol, Terra, Luna) with enhanced safety measures and capabilities, particularly in cybersecurity and biological risk, while maintaining a tiered access approach with government coordination.
OpenAI releases GPT-5.6 to the public after government greenlight, and introduces ChatGPT Work, an AI agent combining ChatGPT with Codex for non-coding tasks. The model suite includes Sol, Terra, and Luna.
