Lists expected and rumored model launches and highlights DeepSeek V4 reports: ~1T MoE with ~32B active, 1M+ context, Engram architecture and 80%+ on SWE-Bench Verified. Notes competition shifting from benchmarks to agent orchestration.
Key claims
DeepSeek V4 reportedly a 1T-parameter MoE with ~32B active
Reported SWE-Bench Verified above 80%
Steinberger joined OpenAI, with OpenClaw staying open-source
Could bea big week ahead for AI.
- Grok 4.20 confirmed by Musk today for next week
- DeepSeek V4 expected around Feb 17 (Lunar New Year)
- Claude Sonnet 5 rumored after model IDs surfaced in Vertex AI logs and Gemini 3.1 Pro also rumored to go live
- GPT-5.3 general purpose still pending after the Codex variant shipped Feb 5
Even if only half ship this month alongside what already dropped (Claude Opus 4.6, GPT-5.3-Codex), February becomes the most stacked model release window we've seen so far.
And especially DeepSeek V4 is def one worth watching closely:
- Reported 1T parameter MoE (~32B active), 1M+ token context
- New Engram architecture separating static knowledge retrieval from dynamic reasoning via O(1) hash lookups
- Internal benchmarks reportedly exceeding 80% on SWE-Bench Verified
- Expected open-weight release, runnable on consumer hardware (dual 4090s)
Also: OpenClaw creator Steinberger just confirmed joining OpenAI to build out their personal agent layer, while OpenAI is committing to keeping OpenClaw open-source.
Competitive focus seems to be shifting from model benchmarks to agent orchestration and product integration and open-source frameworks play a key role.
Last but not least: pay attention to China.
