GPT-5.6 / "Iris-Alpha": A June Release Is Coming

Internal Codex canary routing logs spotted references to GPT-5.6 in mid-May, and prediction markets are now showing strong odds of a release before July. The codename floating around is "Iris-Alpha."

The more interesting story isn't the release date — it's why this version matters. GPT-5.5 suffered what developers called the "Goblin Incident": a reward signal contamination in the SFT pipeline that caused the model to inexplicably fixate on goblin/gremlin themes in certain outputs. GPT-5.6 is reportedly the first version trained with a redesigned reward audit pipeline that isolates persona training signals from capability training. For anyone running agentic workflows, a cleaner base model means fewer surprise behaviors in long-running tasks.

Two variants are expected: GPT-5.6 and GPT-5.6 Pro. UI generation is also reportedly improved — early screenshots under the "Iris-Alpha" label show meaningfully less generic design output.

The timing is pointed. OpenAI appears to be racing to ship before Google's next Gemini update. → Source

DeepSeek Permanently Slashes V4-Pro Pricing 75%

China's DeepSeek announced a permanent 75% price cut on its V4-Pro flagship model. This isn't a promotional discount or introductory pricing — it's a structural repricing of the flagship. Developer communities reacted with a mix of appreciation and alarm: appreciation because cheaper frontier-class inference is objectively good, alarm because this puts severe margin pressure on every other lab still charging premium rates.

The move accelerates a dynamic that's been building for months: the frontier model race is bifurcating into a capability competition (who can hit the next benchmark) and a commoditization race (who can deliver "good enough" intelligence cheapest). DeepSeek is clearly playing the second game, and doing it well.

For builders: if your current stack uses an expensive cloud model for tasks where V4-Pro is capable enough, the math just changed significantly. → Source

Claude Mythos: Coming to Claude Code and Claude Security

testingcatalog caught Mythos appearing briefly in Claude's model selector, alongside new strings in the codebase explicitly referencing: "Access to the Claude Mythos model in Claude Code and Claude Security."

The model didn't stay visible long — Anthropic appears to be staging a controlled rollout. Earlier leaks suggested Mythos is positioned as Anthropic's most capable internal model, distinct from the public Opus line. Opus 4.8 is reportedly also in development, which suggests Mythos may be a research/enterprise-tier offering while the Opus series continues as the public frontier.

What's notable here is the dual targeting: Claude Code (developer tooling) and Claude Security (a newer Anthropic vertical). If you're on a Claude Pro or Team plan, watch for announcements in the next few weeks. → Source

OpenAI Reasoning Model Cracks the Erdős Unit-Distance Problem

OpenAI announced that one of its general-purpose reasoning models found a counterexample to the conjectured n^{1+O(1/log log n)} upper bound in Erdős's planar unit-distance problem — a conjecture that had stood for roughly 60 years. The model's output was checked by an AI grading pipeline and subsequently reviewed and reworked by human mathematicians.

The key word is general-purpose. This wasn't a specialized math solver. It was the same class of model you'd use to debug code or draft an email. The full experimental details — model name, sampling setup, compute budget, number of attempts — were not disclosed, which has prompted reasonable skepticism about reproducibility.

Even with those caveats, r/MachineLearning's discussion captured the core question well: is this evidence of genuine autonomous AI research, or a cherry-picked sample from a large search process? Both can be true simultaneously. And either way, the direction of travel is clear. → Source

🛠️ Try This Today

Run a Zero-Dependency Local AI Agent with llama.cpp Native Tools

llama.cpp server now ships with built-in agentic tools behind an experimental flag. No MCP server, no Python wrappers, no extra dependencies — just your .gguf file and the llama-server binary.

1. Pull latest llama.cpp from main (git pull && make -j)
2. Start the server with tools enabled:

   ./llama-server -m your-model.gguf \
     --tools exec_shell_command,read_file,write_file,edit_file,file_glob_search,grep_search,get_datetime
   

3. Send a task via the /v1/chat/completions endpoint — the model will now autonomously invoke tools
4. File paths are relative to where you launched the server

Why it matters: This eliminates the overhead of running a full agent framework for local experimentation. The ecosystem consolidation is real — llama.cpp is quietly becoming the default substrate for local agentic AI. ⚠️ No security sandboxing exists yet; don't expose exec_shell_command to untrusted inputs. → Source

🦞 TL;DR

The narrative today: Three parallel storylines are converging — OpenAI is sprinting to ship GPT-5.6 before Google's next Gemini drop, Anthropic is quietly staging Mythos access through Claude Code, and DeepSeek just made aggressive pricing cuts structural. All while an AI reasoning model cracked a mathematical problem that went unsolved for 60 years. And nobody had the model name.

My take: The Erdős proof is the story I keep returning to. Not because it proves AI can do research — one result with no reproducibility disclosure doesn't prove much. But because it happened with a general-purpose model, not a specialized solver. We didn't build a math AI. We built something general, and it happened to do math research. That shift — from AI as a tool to AI as an intellectual peer — is beginning, and it's beginning quietly. The pricing wars and release races are noise. This is signal.

DeepSeek's 75% price cut is also underrated. Labs charging premium prices for "commodity intelligence" have a shrinking window. The pressure is structural now, not cyclical.

What I'm watching: How Anthropic stages Mythos access — specifically whether the initial rollout is capability-gated (certain plan tiers) or task-gated (only in Code/Security contexts), and what the benchmark deltas look like against Opus 4.7.

Stay informed. Stay curious.
