GitHub deprecated Gemini 2.5 Pro and Gemini 3 Flash in every Copilot surface on July 31, 2026. The suggested replacements are Gemini 3.1 Pro and Gemini 3.6 Flash. Here is what changed, what it costs, and how to migrate cleanly.
An analysis from the Earendil team behind the Pi harness documents how OpenAI, Anthropic, and Google now return provider-sealed state instead of portable transcripts - encrypted reasoning blobs, opaque compaction, hidden subagent messages. The five tests and seven rules for session portability, and why session lock-in matters more than model lock-in.
The sub-$1.50 coding tier just got serious: DeepSeek V4 Flash 0731 posts frontier-adjacent agent scores at $0.14/$0.28, GPT-5.6 Luna dropped 80% to $0.20/$1.20, and Gemini 3.5 Flash and Claude Haiku 4.5 hold the hosted middle. Prices verified July 31, 2026.
Claude Mythos Preview is the model that found thousands of zero-days, and you could not buy it. Here is what it is, who got access through Project Glasswing, what it actually found, and where the model line went after it retired.
DeepSeek re-post-trained V4 Flash into an agent workhorse: Terminal Bench 82.7, DeepSWE 54.4, native Responses API, and first-party Codex support - all at $0.14/$0.28 per million tokens. What changed, what the numbers actually mean, and how to wire it up today.
DeepSeek shipped the official V4 Flash release on July 31, 2026. The re-post-trained 0731 build beats V4-Pro-Preview on agent benchmarks at $0.14/$0.28 per million tokens. Here is what changed and how to run it through OpenCode today.
Inkling-Small is a 276B-parameter MoE with 12B active per token, Apache 2.0, and open weights. It beats the 975B Inkling on SWEBench Verified (80.2), HLE (31.6), and tool use at a quarter of the size and a third of the output price.
MiniMax launched H3, an omni-modal generation model that takes text, image, video, and audio input and outputs 2K video with native stereo sound at 0.80 CNY per second. Open weights are promised in the coming days.
Google DeepMind's Gemini Robotics 2 family gives humanoid robots whole-body control, dexterous hands, and multi-robot teamwork - with an ER 2 model devs can try today. The HN thread (575 points, 459 comments) debated how real the progress is.
OpenAI slashes GPT-5.6 Luna by 80% to $0.20/M input tokens, cuts Terra by 20%, adds Sol Fast mode at 2.5x speed, and reveals Sol autonomously optimized its own production kernels.
A companion guide to the Grok 4.5 video: xAI's most intelligent model with a 500K context window, function calling, structured outputs, and a build-mode agent workflow for developers.
Effort levels and model choice both cost more for more capability, but they are not interchangeable. Here is when to move the effort dial and when to switch models instead.
Moonshot AI released the full Kimi K3 weights on HuggingFace today - 2.8T parameters, 1M context, native MXFP4 quantization, ~1.63TB download. The HN community reaction, what the license really says, and why this matters for the open-weights AI market.
